The only reason i didn't put 10 is because i live in a really hilly area and the brakes seem very weak/squeaky for going down steep hills and it's also really hard to pedal up the hills. I really should have considered this more when purchasing a single/fixed speed bike. I think they are much more suited for riders who live in flatter areas. I'm still happy with the bike though, i'll just need to build up my leg muscles a lot to get up the hills around here! I also think I'm going to buy a back brake as well. I already recommended you to a friend though!
