How it Works.
Get More out of your bicycle
BionX proportional assistance technology is unique in the e-bike world. Rider input on the chain line (green) provides a proportional response from the motor (blue). Pedal a little and you get a little bit of electric assistance. Pedal hard and you get a whole lot of assistance! And with four levels of assist to choose from, BionX always lets you ride the way you want.
