How long has he had the bike any problems with it yet?I have a friend who commutes about 10 miles each way on his and he loves it...he has one biggish hill to contend with otherwise it's pretty flat...he found it a little under geared and changed the rear for a smaller top gear and was still thinking of adding a larger crank gear....I have a Burisch Synergy which is very similar I don't commute but would be more than happy to use it as a commuter bike..it's similarly under geared, but will happily cruise at 21 mph on pedelec....
