Reddit mentions of Abus U Mini 40 Mini Round Shackle U Lock, 5.5"/15mm Heavy Duty Compact Bike Lock

Take a look at this: http://www.amazon.com/Abus-523137-U-Mini-40/dp/B004HXJRA0/ref=sr_1_5?s=sporting-goods&ie=UTF8&qid=1462161970&sr=1-5&keywords=abus+410

The weight of the kryptonite mini U but the shackle locks on each side so you have to cut through each side to open the lock, just like the $100 Kryptonite NY standard and fahgettaboutit.

Its a small shackle but I use the Sheldon method all over Chicago with this lock and never have to look for a place to lock up. Also don't just buy a lock based on the price of your bike, buy the lock based on how inconvenient/ badly you want the bike to be there when you get back. I have had to leave my bike out overnight way more times than is wise and it, and my bike have always been there when I get back.

The Kryptonite Standard 2 is not going to be cut easily with bolt cutters. Proper locking technique will go a much longer way to bike security than lock upgrades. Don't be this guy.

Bike thieves are largely opportunists. Good locking technique, securing both wheels, and using a decent u lock should prevent 99% of issues. You can't prevent 100%.

I found that the Standard 2 was sufficient for me, though I've switched to the Abus Mini 140, which is a bit tougher and only slightly more expensive.

In your situation, I would get the standard 2 + cable, or the Abus mini and a set of locking skewers if you wanted to upgrade.

Having a second u lock exclusively for home (double lock when at home, take one when out and about) is reasonable -- but probably not necessary. You could buy two Standards for less than one Faghettaboutit anyway.

Don't buy the Faghettaboutit without thinking about securing your wheels, too.

How much you willing to spend? The best money can buy is the Kryptonite Fahgettaboudit but it's pricey.

What I use is the ABUS one. Used it ever since freshman year and still have my bike.

I would suggest ABUS locks, I agree with the other guy ortlieb panniers are amazing! I would also take into consideration what clothes you need to bring to work, amount of clothes, food, etc. If you don't want to carry a backpack but need too carry a fair amount of stuff snag some ortlieb panniers.
Of course a nice pair of lights, i just got my lumos helmet (built in lights and turn signals!). Figuring out layers that you could wear, base layer, maybe wool long sleeve possibly a light jacket?

if you don't want to have to change clothes at work i also really like the betabrand bike to work britches and jeans! check em out on Valancia street.

I recently started using an Abus Mini 140 in conjunction with a cable for my wheels, after using cheap Kryptonites for years. It's small, thick, and has a double shackle. (Kryptonite's double shackle locks are the very heavy and expensive ones). Since its size is minimal, a potential thief can't fit a car jack inside it, and a pry bar won't have much leverage.

Been happy with it so far. Even though it's not big enough to lock a wheel and my frame simultaneously, it gave me a good excuse to carry a cable loop for the wheel I was always neglecting for years anyway. Frame to post with the U-lock, then loop the cable through both wheels and hook it on each end of the U-lock before putting the head back on.

Abus brand locks are almost always 20% lighter, 20% stronger, and 20% less expensive than Kryptonite or more.

This is their equivalent to the Mini.

A post I made about bicycle security practices is here.

you have the mini? (http://www.amazon.com/Abus-Mini-140-U-Lock-140mm/dp/B004HXJRA0)

do you still use the krypto with the mini?

This is the U-lock that I have, does its' job great, but really any will be a step up from the cable lock. Also in general the smaller the U-lock the safer it is.
