Reddit mentions of Vilano Aluminum Road Bike 21 Speed Shimano, Black, 54cm Medium

I've been looking at amazon for some, do any of these look like good ones? Giordano, Vilano, Merax, Schwinn

Also, here is my bike: https://www.amazon.com/gp/product/B005EFTPZC/ref=oh_aui_search_detailpage?ie=UTF8&psc=1

I didn't want to spend too much in case I hated it, but may get a better one in a couple of years. Need a new beach cruiser first.

I'm comfortable putting the bike togeth I'm just worried about getting a bike like the one I linked and not being able to use it in a race.

My seat is at the lowest it can go. Does that mean my bicycle is too big?

So, I recently bought a new bike, a Vilano Shimano to be specific. I used to ride my mountain bike quite a bit, but haven't ridden for a couple years because my bike kept breaking and I couldn't afford a new one. Well I got a new bike, but I am completely new to road bikes.

On the bike above, I bought a medium (54cm). The only problem is, I feel like it's too big, but I might just not be used to it. I am 5' 7" and my inseam is 30". According to adjustment guides, I put my leg nearly straight (but not quite) at 6' o clock. The very tips of my toes (and I mean very very tips) can touch the ground from my seat. I find the position very uncomfortable and hard to control, but I don't know if that's a sizing issue or if I'm just not used to road bikes. (I aligned my handlebars and seat to be level).

So my confusion is, my seat is at it's lowest. Does that mean I bought a size too big? If I did need to go down some, I am completely unable. For context I am a 22 year old female, so there is almost 0% chance that I will grow any taller.

>(I've been looking at Viliano bikes on Amazon

Yes, I looked at what OP said, they are BSO's

I've looked for a beginner thread but can't find one easily. I'm sure it is asked a lot but I'm looking for a bike around $500 CAD ($389.37 US) or maybe that in total with seat upgrades and locks and whatever else I need. I think I'm looking for a road bike but I'm not entirely sure the differences as I've only done light research. I've seen this recommended in those "best under $500" videos but I'm not sure what the best website/store is in Canada. Any links/tips would be appreciated!

Perfect, thanks!

As a follow up, which I maybe should do research on my own first more, is which brands do you recommend for the price point?

I can snag a Diamondback Steilacoom CCX for $630 shipped. Meanwhile I see some unknown brand CX bikes for cheaper on Amazon Vilano road bike 21 speed.

If I go with a CX do you recommend buying a second set of tires that have little to no tred on them for commuting to work purpose? Or just keep the default ones.

Price isn't a huge set back for me. I just want to end up with a quality product that I don't hate, and don't feel I grossly overpaid for said item.

What would you recommend then for something around $300 in a similar style to this. I'm probably only buying a used one then.
