BionX electric bike conversion kits can transform almost any bike into an electric-assist bike. The main criteria is that the bike have a derailleur shifting system. BionX makes several kits to suit your needs for power, speed, range, and weight.
Your Bionx powered bike feels familiar, because it's the same bike you had before, but with a natural boost to your own pedal power. You determine how much of a boost the system will give you.
They are the lightest weight, and most power-efficient kits that are commercially available.
The BionX system can recharge the batteries while you are riding the bike with regenerative braking and a generation mode. These modes can help extend the range of a battery charge, or to give you a better cardio workout -- if you're into that sort of thing.
