u/WildPause · 2 pointsr/vancouver

Happy to help! Ask as many questions as you need. :)
I don't want to make it seem daunting - a good ulock will get you far - so don't let me worry you too much. But in the interest of arming you with the best info:

  • Definitely check with your work/office/school to see if they have any kind of bike cage or similar that you can get access to. You'll still want a u-lock there, but it helps to have that extra layer of security.

  • Of course, no lock is theft proof (enough time with a crow bar and saw or a short amount of time with a battery operated angle grinder, and you're hooped) but if yours is at least a little more inconvenient to wrestle free than others nearby, you stand a better chance. Just enough to make it a pain. I like to use a u-lock on my frame and rear wheel (worth more $$ than a front wheel as it has the gears involved) and a secondary cable lock on the front wheel looped through the frame & ulock.

  • A secondary lock (another ulock or cable depending on the circumstances) is especially important if you have quick-release wheels.



  • How you lock up and what you lock up to matters as much as what lock you use. A really nice u-lock isn't going to do you much good if you're locking just the frame (or forbid, just one wheel!) or locking to a wobbly pole (thieves will loosen the bolts that keep most signs and metal posts in the ground for easy pickings. Throw a hip against anything you plan to lock to to make sure it doesn't wiggle!) Smaller u-locks are safer (less of a gap for leverage with crowbars and the like) but make it harder to find something to lock to if they're too small.

    This is a good guide for how to lock up:https://sfbike.org/wp-content/uploads/2017/01/locking-graphic-01.png
    And a fun video from a classic series where a guy goes around grading cyclists' locking jobs: https://youtu.be/IR8jdnsP4Tc?t=68

    As to the ulock itself? I've been pretty happy with this Krytonite lock It's at the same level as this Abus lock: https://www.amazon.ca/Abus-Ultra-Cobra-U-Lock-cable/dp/B00PHVVKHO/ref=sr_1_4?dchild=1&keywords=abus&qid=1574406052&s=sports&sr=1-4
    If you have a more expensive bike, you can go for something in the $100 lock range, but otherwise this one has served me well.

    Good and relatively inexpensive bike repair shops? I've always been happy with the service I've had from Velo Star Cafe (formerly Tandem Bike Cafe) at Heather & 16th (rather near VGH). Fair prices and reliable friendly service. I've also had good experiences and really great deals from the "Bike Repair Centre" on Broadway just west of Main St. Not bargain basement but friendly and honest and you feel like you aren't going to have to bring your bike back to have someone fix something they messed up. For DIY options (with help!) and spare used parts bins galore, Our Community Bikes at Main & Broadway is a solid standby. It's a community space where you can learn to repair things with help. It can feel a bit chaotic in there and there can be a wait to ask questions or get a stand, but sometimes you can't beat learning a few basic things and coming out the other side with a better functioning bike.
u/Sepheriel · 9 pointsr/motorcycles

I ride to and from work in Atlanta, GA, up and down I-75, about 15-20 each way. Currently it is the middle of summer here and in the mornings its humid but pretty cool. In the afternoons though, if I'm not moving, I'm baking. I deal with it though. My jacket is pretty ventilated but it still gets pretty hot.
However, since this is only when I ride home in the afternoon at 4 PM-ish, its not a big deal cause I can just throw all my clothes off when I get there haha.

I pack all of my lunch and breakfast in this backpack and it all fit really well and the backpack is snug.

I leave my work polo and work appropriate shoes at work, as well as anything I don't want to carry in the backpack.

I ride almost ATGATT, I don't have any riding overpants or otherwise. Plan to get these though. My gloves, boots, backpack and I think my jacket all over some sort of high-viz material on them (silver reflective).

I don't have a bluetooth headset or a RAM mount for my phone. My commute to work is not complicated.

I park on the 2nd level of my parking garage and ALWAYS lock the forks and use a wheel lock on the rear wheel.

I will say you should give yourself more time in the morning to gear up and then to lock your bike and "gear down". I know it has added a good 5 min leaving and 5 min arriving in the morning.

I recommend if that you work up to highway speeds if you plan on doing so. Do not jump on the highway if you don't feel ready. I was pretty nervous and antsy but it wasn't that big a deal. You just have to make sure you're paying attention. And absolutely do not ride in you are "heavy-eyelids" sleepy. Hell, you should drive period. Got to be aware.

I've only started commuting the past two or so weeks and I'm already used to it. However, when the time changes, I might just use my car due to it being dark in the morning. We shall see.

Good luck and ride safe!

u/joshjoshjosh42 · 2 pointsr/ebikes

Oh hey fellow Kiwi! Yeah you shouldn't have any problems getting there and back on one charge assuming your Hills aren't too steep, you'll probably want to charge daily though!

> The main thing I was worried about is lighting, since it;ll be dark while I'm commuting they lights will be super helpful

The lights are super bright and obvious, you can always get a helmet/backpack light if you don't like high-vis but they're pretty bright by themselves.


> I do kinda worry about it being stolen, owning an expensive bike makes me worry, so I'm thinking about buying 2 U-locks. For when I need groceries and the like. I was wondering if you could recommend a few locks? I was looking into it and people say get 2 different kinds?

Not sure if Auckland and Wellington have similar crime rates, although bike wheels get stolen and stuff most people are still using cable locks and rarely get stolen (don't use them though). I've never seen someone go through the effort of cutting a U-lock but definitely get a good one. I would talk to a bike dealer and maybe see if you can get a frame lock fitted,
- I have one on my e-city (it comes with it fitted) and it immobilises the back wheel which is handy for quickly dipping in and out of cafes etc.

I have two Kryptonite U-locks but usually just carry around the Series 4 as it is super bulky and tough - it's the second toughest bike lock to the New York lock and incredibly tough to cut through, even with power tools. Sometimes I carry around the Series 2 for the front wheel and the Series 4 for the frame/back wheel but do keep in mind they are beefy (heavy!) locks. They will definitely protect your bike, I've had no issues parking mine anywhere.


> I like Smartmotion and one of the reasons I am looking at them is due to them being in NZ

They're designed for our conditions so you know they'll last - my dealer said that parts aren't too proprietary and easy to source, they're not too expensive either!

I would also highly recommend getting good pannier bags as they're very useful - Ortlieb bags seem to be the most reliable around but personally I like Linus bags, although slightly less practical because they look nicer - I have the Linus Sac.

u/saviorknights · 1 pointr/UCDavis

Yeah, basically always lock your back wheel and frame with a U-lock to a sturdy, stationary object (There are plenty of bike parking racks. NEVER lock your bike to just itself or another bike). That's bare minimum. That's usually sufficient if you're going to just be in class for an hour or two.

In Davis, cable locks are just a visual deterrent. They're essentially useless, especially if you have a nice bike.

If you have quick-release, either swap them out for regular wheels or be very vigilant about locking both wheels with U-locks.

If you have a nice bike, never park it outside at night on campus. Also, try not to leave your bike outside if you're going to be away (going home for the weekend, winter break, etc.). There are people who go hunting for bikes and bike parts at night and especially during breaks when nobody is around.

It's also a good idea to take a short chain/cable and thread it through your frame and bike seat, just so that's secure too.

Contrary to popular belief, bigger is not better when it comes to U-locks. You want the thickest, fattest, smallest U-lock possible that fits your bike. For example, this mini U-lock would probably do better than this standard U-lock. The idea is, the longer the U-lock, the more space it gives thieves to use for leverage to pry open your lock. I'm not sure if you buy into that, but mechanically it makes sense, and the smaller ones also happen to be cheaper too. Some of my friends with really nice bikes (think $500+) have two small, fat U-locks and they do their job well.

I've also heard that you do want two different types of locks (U-lock and a thick cable, for instance), because that means thieves have to carry two different tools to break the two different locks. This is up to you, and I still think two U-locks are fine.

You can call any bike shop and they'll help! It's worth a try at least. Good luck!

u/MOIST_MAN · 13 pointsr/bicycling

I've created a short list of everything I have, linked items are the ones that I recommend.

Things for the road

Frame/ Mini pump

Saddle Bag

Patch Kit

Tire Boot (You can make your own for cheap, but these are still good)

Tire levers (See Multi-Tool, Levers Included)

Multi Tool (Super-Recommend)

Bike Lights

Spare Tubes (Optional for the road)

Bottles of choice

Sunglasses of choice

Gloves of choice (Important! For preventing impossible-to-heal palm scrapes)

Cycling compter

U Lock (no cable locks! they're garbage) <<I Have 3 of these, but then again, I live in Oakland.

Things for home

Floor pump

Tools (Pretty much covered by Multi-Tool, but there's things you may need like cassette tool, chain whip, etc)

Wet and Dry chain lube

Clothing (Optional, I only have the shoes and windbreaker)

Hi-Vis Jacket

Clipless shoes, I recommend SPD for easier walking

Jersey

Padded Shorts, or Bib shorts

Windbreaker

Leg Warmers

Most importantly, you need knowledge of cycling. Look up videos on youtube about safe riding on the road, traffic laws, hand signals, how to repair your bike on the road and at home, how to take a fall, and as much theory that you can)

EDIT: Do not let me trick you into thinking that a multi-tool is a replacement for the big-boy tools that are available on the market. Some of those tools are actually worth the investment. However, be that as it may, do your research first, because there's some overpriced crap out there ^^^Park ^^^Tools.

u/lescannon · 3 pointsr/bikecommuting

At 3 miles, you could walk that in 45 minutes, so 15-30 minutes to ride each way depending on the hill. Good that you are planning it now, instead of waiting till later. I think the first thing you need is a feasible route. Perhaps you already do, but it is more pleasant to ride without a car behind one. So perhaps you can ride much of it on roads that are less busy and likely have a lower speed limit. Google Maps has a bicycle option so you could see what that suggests. When you get your bike (or if you can borrow one), ride the route early on a weekend morning. Check that there is someplace to lock the bike at/near the school, because you need to securely lock it. The lock deters a thief by making it more difficult, not impossible to take. The more expensive the bike looks, the more formidable the lock should look. If the front wheel has a quick-release skewer, you should secure it so something like or this

I strongly recommend a helmet. They all meet the same standards, so I buy less expensive.

There are lights that help make you visible and those that help you see the road as examples, but not recommendations.

You've thought about rain for your backpack, but you may want to consider for you too, because being soaking wet at school is no fun, rain jacket, rain pants and fenders. I have a pair of these which might be a good choice if you can carry other shoes to wear in school. Even without rain, it will seem colder when you are going downhill in the morning, so I use running gloves (full finger) some winter mornings. You can bundle up toasty warm for the mornings because you don't have to pedal that much, and then carry some of your clothes instead of wearing when you ride home, so I recommend a rack and a couple of bungee cords to help with that.

Since it is a walk-able distance, you should probably leave the water bottle, multi-tool, patch kit and pump at home on school days just to keep it simple and keep from losing those things. It probably makes sense to keep it minimal and cheap while starting out like this. If you get a floor pump with a gauge, you can use it to check the pressure once or twice a week and then learn how to feel the tires to see if they are firm enough. I've not found a mini-pump with a gauge that is universally regarded as reliable, so the pump I take with me has no gauge.

For your commute to school you shouldn't need to fuss with padded biking shorts or spandex shirts or even fingerless gloves. I rode quite a bit when I was your age without any of those. If you are looking at longer rides, then you might want to try some of those (no underwear under the biking shorts) to reduce chafing against the seat and wind resistance from floppy clothing.

u/TheManWithNoName · 2 pointsr/bicycling

I think where you live and where you leave the bike has an effect. I'm in Rochester and most of the other bikes I see around are locked up with cheap cables, especially at RIT. Those wouldn't last a second in NYC, but it makes me more comfortable with a reasonably strong U-lock (though not as tough as the Fahgettaboutit). I don't use locking skewers myself but I've heard good things over at bikeforums.net and I have considered picking some up. I tether my saddle and rear wheel with a cable when I leave my bike in less safe areas but it would be convenient to only have to worry about locking the frame.

I have the Trek-branded version of this lock:
http://www.amazon.com/Kryptonite-Kryptolok-Standard-Bicycle-U-Lock/dp/B000LPEXDO/ref=sr_1_6?ie=UTF8&s=sporting-goods&qid=1247973444&sr=8-6

You certainly wouldn't go wrong with the lock you suggested, I got this when I was riding a cheaper bike than I am now and as I said in generally low risk areas.

I think the most important things are to use a lock greater or equal to the typical lock for your area and have decent locking technique.

u/Meowface_McGee · 1 pointr/bikecommuting

Good choice on the single speed bike, very utilitarian. There's a little too much chain slack in this picture though, you'll want to tighten that a little so you don't drop your chain. If you've got hills and it gets too hard to pedal, consider getting some foot retention or consider lowering your gear ratio by getting a slightly smaller chainring. Like others have said, definitely ditch the cable lock and get a U-Lock. I carry mine in a belt holster for convenience, it makes the bike feel much lighter than when you mount it to the frame. Other than that leave a spare change of clothes (including shoes and everything!) at work for peace of mind and don't overthink it, do everything you can to make sure it stays fun!

u/WiseBeardy · 1 pointr/Eugene

I'm using a mid-level U-lock currently
https://www.amazon.com/gp/product/B00LOABKJA/ref=oh_aui_search_detailpage?ie=UTF8&psc=1

Maybe what I'll do is fix up the old bike (Giant OCR 2 road bike from 2003) with some non-high end wheels / tires / cogs. It's a decent looking road bike, but definitely not as good looking as the new black Breezer I'm getting. It could be my "beater" for when I need to lock up in less-than-ideal areas.

A friend showed me sites where I can order parts directly. Is that the best cheap option for getting that one operational again? Any places for getting used road wheels / etc?

u/[deleted] · 1 pointr/bicycling

For the best security I always prefer ulocks over chains. I have this ulock that the length makes it easy to catch the frame a wheel and the post. http://www.amazon.com/OnGuard-Pitbull-U-Lock-Black-9-06-Inch/dp/B008MZ0A3M/ref=sr_1_2?s=sporting-goods&ie=UTF8&qid=1380667120&sr=1-2&keywords=OnGuard+Brute+STD

But if you're not too concerned about security then you're linked chain lock seems like a fine choice.

u/pentium4borg · 1 pointr/Frugal

/r/bicycling and /r/whichbike should be able to help.

Don't buy a department store bike unless you want it to fall apart in 3 weeks.

Get a good bike lock for your next bike. Cable locks can all be cut with bolt cutters in 5 seconds. You need a U-lock; something like this at minimum, this is better, and I have this which is one of the best locks available. Learn how to use your bike lock properly.

u/OmgMacnCheese · 5 pointsr/UCSD

I would stay away from UCC. They pretty much only deal in Specialized bicycles which are usually over priced for the components that you deal with. I've been riding for a while and essentially, the different brands are simply stickers on the frame. What you want to look for are the components (frameset, derailleurs, forks, etc).

In terms of locks, buy a nice OnGuard lock that has a U-lock and a cable lock for the front wheel. Lock it like the Sheldon Brown technique.

u/dnorm00 · 2 pointsr/boostedscooters

I've used this one for my bike and it works well for the Rev:

https://www.amazon.com/gp/product/B001DWNK1A/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

It has a bit extra reach over some of the more standard length U locks allowing you to reach 'lock to' devices more easily.

This lock is a bit heavy, but with some velcro ties it straps around the stem and to the frame nicely. I saw the idea for this here:

https://www.reddit.com/r/boostedboards/comments/cqjugl/neat_way_to_carry_a_ulock_on_a_boosted_rev_scooter/?utm_source=share&utm_medium=web2x

hat tip to: u/kenzanboo for the \^ tip.

u/littlejohnnytables · 1 pointr/Locksmith

Here is an example of what a motorcycle u disc lock looks like.

https://www.amazon.com/Kryptonite-Premium-Packaging-Orange-Millimeter/dp/B0030M4DAI/ref=sr_1_4?ie=UTF8&qid=1481657678&sr=8-4&keywords=motorcycle+disc+lock

These are used to attach chains to the frame or disc rotor of motorcycles.

They don't have removable wafers, so they can't really be re-keyed (as far as I know, an I think I am using the right words.) so they have to be made with the same key from the factory.

Thanks for any help.

u/heyyyaaaa · 1 pointr/NYCbike

Thank you for the response. I'm looking at this combo:

u/HappyGreenGiraffe · 2 pointsr/ElectricScooters

Thank you for the detailed comment, I dont have the scooter yet. I wanted to ask if the 60$ kryptonite you recommended could be a tight fit over the frame bar that I highlighted in the picture, is locking from the rear wheel/disc brakes also a viable method for shorter periods or time eg.going to grocery store in city center?

Edit: what would you think of this? Could it have any use?

https://www.amazon.de/dp/B06XCPH1S4/ref=pd_aw_sbs_200_2/258-5096114-5324401?_encoding=UTF8&pd_rd_i=B06XCPH1S4&pd_rd_r=a8d50065-847c-4bf2-9106-10358856d0bc&pd_rd_w=OEBCD&pd_rd_wg=2eV0H&pf_rd_p=2dc4f796-cca2-422e-a5f2-34ec116afab8&pf_rd_r=1MRRH92HZB603GEJ9CXT&psc=1&refRID=1MRRH92HZB603GEJ9CXT

u/kbrosnan · 1 pointr/whichbike

Yeah. Spending $100 to lock up a $300 bicycle is not worth it. Get a solid $30 lock like this On Guard, do a recycled chain seat post retention and hose clamps on the quick release skewers like the first A graded bike at http://www.streetfilms.org/hal-and-kerri-grade-your-bike-locking/

Via Velo Bike U Lock with Cable... https://www.amazon.com/dp/B01KD9AQ92?ref=yo_pop_ma_swf
Works really well for me and I trust it more than my Kryptonite U lock, and it’s one of the cheapest on amazon

u/dylanholmes222 · 2 pointsr/Boise

I use this Kryptonite lock for $67, it's very solid and works great. It's not too heavy and you can mount it on standard cup holder inlets.

u/stilz · 1 pointr/bikecommuting

Thanks for the recommendation, I've heard of that lock. This is what I have: http://www.amazon.com/Guard-Bulldog-Mini-Lock-5015/dp/B004S55H7O and I'm aware of this locking method:
http://www.sheldonbrown.com/lock-strategy.html

My saddle is fairly basic, so not too worried. Are shifters and derailleurs fairly secure?

u/punth · 2 pointsr/bicycling412

$30

The theory of bike locking (per Sheldon Brown), is U-lock your frame and back wheel to the stationary object (which you have to make sure is stationary, some street sign posts have bolts that are easily removed; and wood like on your deck can be easily broken). This is why a larger/longer U-lock is often necessary. Then a cable can be run from the U-lock through the front wheel.

[Edit] Alternatively for more protection, a second U-lock can lock the front wheel to the frame at the down tube, then the cable can run from either lock through the stays on the saddle to prevent saddle theft.

Ultimately every lock can be broken, the goal is to deter and slow down potential thefts.

u/TheSiwentKiwwah · 2 pointsr/bicycling

I got a pretty solid u-lock at Marshalls for like $15...so if you have anything like that near you, you could check there.

u/tokenhoser · 2 pointsr/saskatoon

This one is what I bought for a balance of security and cost. You also want a cable to tie your wheels to the u-lock, especially if you have quick-release wheels. We swapped our quick-release for security bolts.
Nothing will work if they really want it and have the tools to take it, but I try to be less attractive than the next one over.

u/Kazyole · 3 pointsr/bicycling

How big of a lock would you need?

I'm a fan of the Kryptonite New York series personally. They're super heavy duty...I can't imagine cutting through one...There's a 4x8 and a 4x10.25

I use the 4x8 to lock my frame and back wheel, and one of these bad boys to lock my front wheel to the frame.

It's overkill...I know...but I'm in New York.

Amazon is actually very reasonably priced on all of those by the way...if you're looking to order online.

u/NeptuNeo · 1 pointr/BikeLA

some good options to consider are these:

Its pretty decent looking bike and it'll probably be locked up for a day at most so do you think it would worth upgrading to https://www.amazon.com/Kryptonite-York-Heavy-Duty-Bicycle/dp/B06XN5GV9K

As others have said keep it inside, these are not bad.

The idea of making it look cheaper too is a good one. Wrap tape around and cover it in kids stickers.

The Kryptonite I use is a U-lock. Pretty heavy duty and heavy.

https://www.amazon.com/gp/product/B001DWNK1A/ref=oh_aui_search_detailpage?ie=UTF8&psc=1

The cable is to lock the wheels and seat, not the bike itself. The bike is locked by the U-Lock.

Trackr is just Bluetooth based. I work too far away from my bike. I was thinking more along the lines of a TK102-2 (original) with an iOT Sim. There is also a satellite based one: Spot Trace. Costs $100/year in service in addition to the device and sends a ping every 5 minutes.

Currently I have ordered.

  1. Front light
  2. Multi Tool
  3. Phone Mount
  4. Bike Lock

    When I go the the LBS to pick up my bike, i'll bet getting a CO2 pump as well.

    EDIT: I only plan on bringing my lock if i'm going on longer rides not @ my local park. If i'm not on my bike it will be in my home.
u/drossen · 1 pointr/klr650

I have one of these

You can get just the lock or just the safety cable or get them separate without the bag for a bit less.

u/Spartan_Beard · 1 pointr/Super73

I recently bought a Kryptonite U lock when it was on sale. This version has an extra long 'U' and fits through the rear spokes and back of the frame (not the tire) and enough space to attach to a bike rack.

https://www.amazon.com/gp/product/B06XN5GV9K/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1

And I use a HipLok Lite chain as an extra to secure the front tire, if needed.

u/SwampOfDownvotes · 2 pointsr/boardgames

Then if you buy it at the higher price then you think its worth the money. You can also google and find the MSRP and wait for it to come down if you don't want to support higher prices.

It's only an issue if it's your only option for something important (i.e. Food or water) and not just something you want. Especially when it's not hard to find something that does the same thing for cheaper

This has a 4 and a half in loop. I'm sure if you kept looking you'd find one

u/Cik22 · 1 pointr/malelivingspace

It's a kryptonite u lock. They make a bunch of different ones. this one has the attachment that holds it to your frame.

u/mattgif · 1 pointr/frugalmalefashion

31" waist, fits my kryptonite evolution just fine. What sort of lock do you have?

u/hahncholo · 2 pointsr/Triumph

I use this one: https://www.amazon.com/Kryptonite-Premium-Packaging-Orange-Millimeter/dp/B0030M4DAI/ref=sr_1_22?ie=UTF8&qid=1501886853&sr=8-22&keywords=u+lock+kryptonite

on my back brake and run the reminder cable over my seat to the opposite side rear turn signal. Works great. No one's tried to take it yet, but I do live in a big city (San Francisco) and have parked many times in sketchy areas.

u/rozetto · 1 pointr/bicycling

Not sure about the other parts, but the first thing I usually check is Kryptonite locks. La Bicicletta has the standard 4x9 4 series for $89 and Amazon has the same for $70

u/jimbonics · 1 pointr/Austin

I use one of the longer OnGuard U-locks. Hasn't been a problem, yet!

u/pacmanwa · 2 pointsr/ebikes

I'm using a Kryptonite ulock with cable at work. Bike rack at work is a joke though, its not secured to the floor or wall. In the garage at home, auto door closer so it will never be open longer than 5 minutes unless the power is out.

u/showmethestudy · 1 pointr/videos

Any thoughts on the Cocoweb ArmBar Bike U-Lock, currently Amazon’s choice for bike locks? 14 mm heated alloy steel shackle. Disc cylinder system using flat keys. Looks solid to me. But fairly cheap.

u/NorthernLove1 · 3 pointsr/duluth

A cheap tool that fits in a pocket can cut a wire bike lock in seconds. Wire bike locks are invitations to thieves, unfortunately. Get a good U-lock. Good luck!

The one thing about Amazon is that they still put stuff from Amazon.com in Amazon.ca, but just adds the extra shipping and customs. If you change the URL to .ca, you may see the exact same product but it can be shipped from a Canadian warehouse, or you can find an alternative on Amazon.ca.

Depending on how long I'm leaving it out, I'll use another cheap chain lock on the front tire in addition to the u-lock on the frame.

u/MixMasterHusker · 1 pointr/lincoln

With enough time anyone can steal a bike regardless of the lock used. You want to make your bike harder to get compared to the bike next to yours.
There are many videos online discussing this topic but it comes down to quality U-lock or heavy-duty chain and proper lock technique.

Like you, I got an e-bike so I didn't get sweaty on my commute to work. I got 2 locks. A destination lock that I left on the bike rack at work. And a U-Lock I kept in my bag for when I ran errands. I extra-long U shape allowed some flexibility locking to various racks.

As for an e-bike I suggest getting one from a local store that has experience working on e-bikes. I don't know if Speedy Pete's repairs/maintenance but I would imagine they would. Many of the repair shops around are hesitant to work on my e-bike.

If you can, get a bike with a mid-drive motor. I had many problems with my hub-drive.

u/Spike69 · 5 pointsr/CalPoly

I am going on my 4th year here. I had my bike lock cut because I left it for about a month.

The way I see it, over time your bike will definitely be looked at by bike thieves. If you have a U-lock they will move on. If you have a nice bike and a cheap cable, then it may be cut and stolen. Keep it safe, invest in a U-lock and you will not need to worry. ^^^Hail ^^^Corporate.

u/bonesfordoorhandles · 1 pointr/ireland

Sorry dude but that lock is thief bait. They are only to be used to securing a quick release wheel. They can give a bit off added protection from people just yanking the bike off the stand but I've seen similar be taken off (legitimately) in about 10 seconds.

For the last few years I've been using a kryptonite evo with a cable for short term locking and then I had a kryptonite New York m18 that I would leave at college or bring if I was leaving it in town odder night. It's pretty heavy for just bringing to the shop.

I know it's a lot of investment but it beats the hell out of buying a new bike on a regular basis.

Davis native (lived outside city limits but whatever) and UCD graduate. Olive drive is one of the highest crime areas of Davis (according to the police crime statistics, down town and the frat area is FAR HIGHER). However this is Davis, so when I say high crime for Davis, that still means very low crime.

So the worst thing that happened to me on Olive Drive was being yelled at by a homeless man. I was walking on one of the bike trails (the one that connects campus to Murder Burger, and yes it is Murder Burger). The homeless man was camping in a drainage ditch and woke up because my friends and I were speaking loudly. He chased us for about a minute. It spooked us pretty bad but looking back I don't feel we were in any danger.

Downtown and any place on campus will have drunk students, which frankly are more dangerous than the Davis homeless most of the time.

There is a mobile home park south of olive drive, they used to generate a lot of crime that spilled into the olive drive area. The mobile park has been cleaned up however (rent prices jumped, funny how that works) so it isn't much of an issue now.

Here is a list of things I think you should know.

  • Olive drive is near the Murder Burger and In-N-Out, if you are not careful you will gain weight
  • The road connecting the I-80 off ramp to Olive drive is riddled with pot holes. Be very careful driving it.
  • Most party nights in Davis tend to end near Murder Burger, In-N-Out, I-HOP, or one of the bars in downtown near the toad hole (the bike under pass near Olive, I'm not sure what you kids are calling it these days), so if you live on Olive Drive drunk friends will crash at your place. I would suggest keeping bottled water, a few extra blankets and pillows, and some accessible condoms in the main room of your apartment.
  • For walking around late at night I would suggest one of these. They are very bright, the mag-light is also heavy duty enough to be used as a defensive weapon should you need it. However running is a far better option and the light should be plenty to get a head start.

    Edit Don't forget to lock your bike, they will take it if you don't**. Get a heavy duty U lock. Spend at least $50.** I would suggest something like this.
