Recumbent Hand Bike with Electric assist
I want to build a recumbent Hand Bike with a 180deg crank. 2 wheel version,not a trike. I have 2 artifical legs, so it will be good for my fitness
I am thinking I can use an electric motor on the rear to get the bike up to balance speed. As the pedals will be driving the front wheel.
Keep in mind I need to keep it as light a possible.
Question is what is the lightest setup for me to use, running 5-600w motor as I will have to pedal the mass with my hands?
I loved the bike built by Recumpence (Matt)

I think the answer is that any electric system will be powerful enough to use as a pedal assisted electric bike, but the weight and friction of an electric system makes it less desirable as a pedal bike with occasional electric assist.
Hubmotors are an easy way to buy a kit and have a bike going in a few hours.
There are other ways, but there is a learning curve.

A brushless, geared hubmotor will freewheel, removing any cogging drag when you are not using the assist. The low down torque will also be a significant benefit if you need to climb any sort of serious hill.
