Default Re: Regenerative Braking

In the eCycle, the electric motor/generator and the Yanmar diesel engine are geared together and turn a common output shaft. An electronic control unit switches the motor/generator from motor mode (accelerating the bike) to generating mode (charging the batteries) depending on the load required by the throttle-by-wire. If the bike is moving faster than 12 mph and not accelerating the engine applies enough torque to the output shaft to both maintain speed and charge the batteries. If the throttle is closed, the momentum of the bike supplies the regeneration power.

Because regeneration requires power, both the motor/generator and the engine supply engine braking. The brakes themself have nothing to do with regeneration.

Default Wrong and right

If all the weigh is on the front wheel, locking the rear wheel will have no effect whatsoever. Until you release the front brake, at which point you are toast.



The eCycle approach would have to be combined with a slipper clutch to work for racing.
