    2-wheel drive?

    Attempts to drive both wheels on a bicycle have always been a mechanical nightmare, but on an ebike it should be easy. Is anyone doing it?

    I'm thinking of this for hauling loads and tractor-like applications.

    With a front hub motor? And a regular one for the back wheel. How would you work the power?

    I rode an Easy Motion (BH Industries, the Spanish conglomerate) with 2WD. Lots of fun, but, even with a sensor that adjusted the power when one wheel started to slip, didn't notice any advantage over 1WD. The real fun was when the torque sensor (apparently) got stuck and the bike flew up a fairly lone, relatively steep fire road. Also, I had a front hub motor with rear 8-speed derailleur; fun, but nothing special.

    Power through the front wheels undoes the self correcting nature of your front steering. It becomes unstable and requires a firm grip on the bars.

    So you can do front wheel assist. But it needs to be linked to the torque and speed applied to the back wheel.

    You would have to have both motors run off the same controller and both motors would have to be the same as well so the power output is identical on both. It could successfully be done but the need just isn't there. I've put my rear wheel moto bikes places only goats go. The actual need for the front wheel to be turning would be far less than 1% of the time.
