As with cars, electricity is playing an increasingly large part in two-wheeled transport. (telegraph.co.uk/motoring/motorbikes/4398827/Electric-motorcycles-current-production.html)

Europe’s Piaggio -- MP3 Hybrid Motorcycle is due to go on sale this summer.

Oh how fun this could be :) -- Ed.

The incentive for motorcycle and scooter manufacturers to produce electric and hybrid two-wheelers is less obvious than with cars. Already they're making many small capacity machines with an everyday economy of more than 100 mpg. The emissions regulations are easier too, with no imminent requirements to sell a certain percentage of low-emission vehicles across a product range, and less strict exhaust emission rules for individual machines than is the case with cars, although these are converging.

Perhaps the biggest problem is the packaging, particularly with regard to battery storage.

Then there's cost: $14,250 of batteries in a $85,500 car might sting a bit, but with $2,130 scooters there's little financial scope for pioneering, and therefore expensive, technology.

Even so, progress is being made and we've highlighted the state of play of alternative fuels for bikes and scooters with four examples: one on sale now, two about to go on sale and one still at the prototype stage… http://www.telegraph.co.uk/motoring/motorbikes/4398827/Electric-motorcycles-current-production.html

That U+S model is intriguing!

Interesting stuff, but kinda' expensive for now. I would like to hunt up a DIY kit. The owner would supply the rolling chassis and would somehow strap the motor in by welding on brackets, and the kit would be the motor, batteries, charging setup/converter to charge from 120 volt household current, controls and some sort of connection to the bikes lights, signals etc.
Anyone know of any DIY kits out there for motorcycles, not light bicycles.

phoebeisis did you google the DIY bikes? I thought the instructables was interesting:

http://www.instructables.com/id/How-to-build-a-72Volt-electric-motorcycle/

Claimed $3000 with lead acid batteries, 10 mile range. I'd like to see this done with lithium and maybe for $5k.

Tochatihu-impressive, thanks. I've been tempted to see how well a bicycle electric kit would work on a much heavier motorcycle chassis. Quick answer is that it would probably barely move even with some regearing.

I have 2 SR500 rolling chassis in my backyard, sure would like to find some use for them.
I noticed the bike he started with had a fairly small "diameter" square tubing ,so it had plenty of room in the engine/battery compartment.
Thanks,
Charlie

The metricmind web site shows a variety of electric motors, but are they all AC and need inverters? It seems that the one-to-few horsepower bikes all seem to use DC motors.
