Hybrid electric conversion of vintage Honda Hobbit PA50II moped
 

I have a an awesome 1978 Honda Hobbit PA50II moped that gets about 100 mpg , goes 30 mph and takes me about 100 miles between fillups:

I want to convert it into a gas/electric hybrid in the simplest way possible. Feedback on my idea, please:

Add a front hub brushless motor wheel with built-in internal controller like the MagPie series.

Then slap a Lithium Polymer battery (which already have from my folding electric bike)) on the back rack, a throttle speed controller and a power switch on the handlebar.

Then I can use the Hobbit's gas engine when I want, or switch to electric power when I want.

Comments? Flaws? Tips? Thanks!

If you could dampen it, you could hook a vacuum diaphragm up so that any time the engine was under low vacuum (open throttle) the electric motor would kick in allowing you to use less throttle, of course dampening the pulses would require a small reservoir but it should work just fine, then assuming that your throttle is just a 0-5k ohm throttle you can have dual throttle inputs and even have a switch to switch between them.

I like the original concept with separate controls- completely up to the operator to decide what blend of what power source to use. Do it! And let us know how it goes.

Yeah the idea is to be able to use electric power when travelling at low speeds, and to get to a gas station if I happen to run out of gas. And also to get more miles out of each tank of gas.

I've been thinking of doing the same thing only different: putting a gas engine on my electric bicycle...

Hey! You got peanut butter on my chocolate!

Well you got chocolate in my peanut butter!

I think both, automatic assist & manual throttles would be brilliant. TBH I'm grateful for the vacuum diaphragm actuator idea, thx!

Something like this, maybe............http://www.youtube.com/watch?v=ZRjWA...eature=related
