E-BikeKit is offering a lower power, lighter weight, internal gear hub motor to their kit lineup. These kits are 350 watts and have slightly less top end speed than the higher power direct drive hubs unless run at 48V. Even though they’ll run at 48V, they are only warranted at 36V.
Because of the internal gears, they have good torque at lower power. Maybe not as much torque as the higher watt direct drives but they do have a significant weight advantage.
It’s a good balance between power, torque, and weight. This would make a great motor for a commuter bike. I’ll be installing one soon and will share all the details about it. More videos and photos on the way.
P.P.S. E-BikeKit is offering free shipping through December 2nd, 2010 for orders over $25.
