Great bike!
Nicely made bike and well set-up in the store. All parts seem to be high quality. My daughter hasn't put a whole lot of miles on it yet, but it's her first multi-gear/hand brake bike and she was very nervous. One little ride down the street and she was loving it. The finish on the frame seems very even and quite thick/durable. The grip shift mechanism for the front gears does seem to be a little tight but that might be able to be adjusted. The gears don't slip out at all. Great bike!
Worse than previous Co-Op bikes
Other co-op bikes have been great but this bike has been real trouble. Badly designed rims with little tube protection led to a popped air tube. The tube used is an uncommon size making changing it harder. The derailleur has had continual issues. It popped the derailleur wire loose. The front derailleur has had trouble shifting into the highest gear as well. Too many problems to reccommand
