I bought my Pedego Comfort Cruiser at a local "green technology" show here in San Diego back in June 2009. Its now July 2011, and the only issue I've had with the bike is a flat tire. Almost 1500 miles showing on the aftermarket odometer now. I use the bike for weekend exercising and enjoyment. My only critique is that it is geared too high for such a heavy rig ! I addressed that issue by changing-over to a smaller front sprocket ( 50 bucks at my local bike shop ). Battery performance has remained constant even after more than 100 charge / discharge cycles. Am very happy with the rig! Dave M in San Diego, CA.
