Im a 100% disabled Veteran and have bad knees that prevented me from riding bikes. This bike has made it possible to do that again! The pedal assist modes are fantastic, I can pedal and exercise, but when my knees start hurting I can go pure electric mode and rest them. It climbs hills with ease and the ride is very smooth. I've put 12 miles on the bike so far and Im loving it more with every ride. I highly recommend this bike to everyone!
