I'm an experienced road cyclist but know virtually nothing about single speed/Fixies. While in SoCal last week looking for apartments for my son we bought him a 6KU entry level bike. It's very stylish with a bright orange steel frame and Very deep wheels and that's what he wanted. After only a few rides, a number of issues have come up. At this point I'm thinking he should take it back to the shop where we bought it and ask for a full credit towards purchasing a higher end bike. What do you guys think?
