If you know nothing about bikes, please don’t even consider buying this bike. Go to your LBS (local bike shop) and get some help. You’ll end up with a bike you want, a bike that fits, a bike that works well, a guarantee, and a place to bring it if it needs work.
FWIW, this bike is a fashion statement. It’s a cheap fixie. Nothing wrong with fixies at all, but the person that would want a fixie would want something better.
I was wondering if the bike is supposed to come with the decals. I just received and assembled my bike today but it did not come with the decals
