Hello all, Atlanta GA here i bought one of their bikes and i love it ! it does just about everything they said it would do. Battery last about right of course it depends on the road conditions, weight as i carry all my groceries and garden supplies in the bike cart that i pull with the bike. i did have a problem with bike running odd battery going in and out i called and got hold of someone rightaway not sure what others are talking about i NEVER had ANY trouble getting a hold of anyone there, worked with chase to figure out what was wrong, we first replaced the controller he sent me a new one 2 day shipping i replaced it with his step by step help on the phone as i did it !! But that was not the Problem ;( , so they found a bike shop here in Atlanta i took it there and 2 days later it was fixed it had a loose connection were the battery connects to the motor. worked Great ever since. Not sure what else i could ask from these guys that they have not done. Great Service great bike, I am Happy !!
