E-Bike frames

This is the best e-bike frame I have ever seen. Most frames are not made to hold all the batterys and electronics. This would be a very good job for a custom frame builder.

This would make a very strong cargo bike, but the motor still needs to be in the center because hub-motors are worthless for hauling hundreds of pounds up steep hills.

Geared hub motors are not available in more than a 5:1 reduction ratio. And direct drive hub-motors are set in such a high gear that you would need much more energy to climb any hill.

Belt Drives are the Best
