I was looking for a full-sized (700c) commuter bicycle that I can easily lug around on my daily commute into NYC. Need to ride over 10 miles one way, be compact so would be allowed on transit systems, and easy to move around when in buildings. I looked long and hard for about 2 years, with only one company out there offering something close to what I needed. But their bike can't be rolled so that wasn't good.Then I happened upon the Change bike. It fitted my needs; everything checked off. Was able to see it and test ride it, so ordered the bike in late May. I'm 5'7" & the medium fits me just fine. The bike came about 10 days later and everything was in order. Wheels were true, nothing needed adjustment. Just had to attach the front wheel, saddle, then go! So far, after a month of testing and 360 miles, I am very satisfied with the purchase. Frame is solid, no flex at all. I did a 57 miles ride with it already, and am looking forward to do a century later this month on the Change. Only thing I would "change" for that ride is a more comfortable saddle and clipless pedals. So I would give it 4.5 out of 5 stars. The U.S. distributor extends the warranty from 3 years from the manufacturer to lifetime, so you can't beat that. He's very quick to respond any questions and requests that I had, so I would give the reseller 5 out of 5 stars for outstanding service. I would recommand others to compare this bike versus that other full-sized commuter bike.
