Electric bicycles and other EV's

Here's an interesting concept, a 2wd gas-electric hybrid bicycle assembled from existing components, notably a small gas powered generator on the rear rack.

Three subjects that regularly crop up are these:

Using twin motors on an e-bike.

Having a generator on board.

It's actually a fully working Lafree Twist with an added Heinzmann hub motor in the front forks. Both motors separately and individually use the battery built in to the Twist's Panasonic power unit, but with the generator that's mounted on the carrier, both motors can run together at the same time giving two wheel drive.

Together with pedalling only, that's a four way choice of travel mode.

Petrol consumption with all on is roughly 450 mpg with 240 watts generation. The weight with petrol is 36 kilos, still much less than a typical SLA battery single motor model like the Powabyke.

Hmmm...
