Visit or google Papamotor and order their 1000 watt 48 volt system with 15 amp battery. Top speeds at 32 MPH distance at 18 MPH at 29 miles per charge. Get the optional 5 amp charger and charge is cut in half or more to about 3 1/2 hours. For mainly road unless u do steep hill climbs, get the front hub motor kit. You won't regret your decision and forget pedal assist. Eventually u won't be happy and kick yourself with what you paid versus what you could have had. This is the best advice you'll get.
