I have a spare alternator kicking around as well as an inverter. The bike itself will be a ground up build, frame and everything... ATM I'm not too concerned about weight, as much as I am about the possibility of it working at all..
Thanks for the reply

If you can generate 300w of power (or any amount for that matter), it's better to apply it straight to the wheel. You'll lose energy when you go through the alternator, the inverter, the battery, and the electric motor. Not to mention, you'll be carrying the extra weight of the alternator and inverter. If you just want to charge your e-bike batteries when you don't need to move at the moment, then finding a e-bike with regen is better since you don't have to carry extra components.
