I’ve been following BH E-Motion’s e-bikes for several years. In the US, BH E-Motion is well known for their fitness equipment. In Europe they’re also known for their e-bikes, which have 4 types of technology.
- NEO RDS (Rear Drive System) Technology
- BOSCH IBS (Integrated Bottom Bracket System) Technology
- PANASONIC IBS (Integrated Bottom Bracket System) Technology
- EASY MOTION FDS (Front Drive System) Technology
This past September, while at InterBike (the national bicycle convention), I had the opportunity to test ride all of these systems.
The revolutionary Neo RDS technology uses a 350W motor (1 on the diagram). This was a nice powerful motor in the rear of the bike with the torque sensor (2) located in the rear drop out of the frame. This registers the force exerted by the rider and sends a signal to the controller (4). This action is fast.
