Got mine on amazon for a tad bit cheaper so far i got 430 miles on it, ride it 19 miles a day to work and back, really fun and pretty quick with 28psi i can get up to 33mph to 35mph i weigh about 145lbs an probably have about a 30 lbs in my backpack an i still get up to 35mph on the way home, i only get up to abput 30 to 33mph on the way to work because its slightly uphill but its extreamly reliable rain, wind, sun, cold nothing seems to stop me id really like to get another backwheel with the motor and another battery but i dont see a way to get one unfortinatly. If anyone knows please comment !
