The Dyname 4.0 drive system is powerful, delivers high torque, and is long-lasting. That means faster climbs, punchier acceleration, and a larger, removable battery helping to ensure that you get more out of every ride. Designed in Canada, we’ve kept the same massive power as our previous generation drive system, but fit it into a smaller and lighter package. The Dyname 4.0 drive system delivers power in a responsive and natural way, giving our bikes the best e-bike ride feel on the market.
