" You guys are missin' the point... if you drive the side wheel, the rig will want to go straight. If you wire in some kind of microswitch to the tripleclamps that will cut the side wheel power off when a turn is initiated, that might work. Otherwise, the rig will be difficult if not impossible to turn. That's my experience racing mx sidehacks talkin. Just sayin "

The theory follows that you spec this "assist motor" to:
A - motor only, no regen
B - set cut in from standing
C - have a fairly low cut out speed
D - be readily overpowered by the main drive wheel so that low speed maneuvers don't suffer from 'solid rear axle' behaviours.

You'll need to have and RPM sensor on the main wheel and control the assist wheel to match rotation.
Not necessarily true. If the controller is in torque mode, it shouldn't matter. You'd just need to mechanically tie in another throttle so you can control the motor controller. If you push the accelerator, both engine and Controller will increase speed. The controller will not care about RPM, only the torque commanded to it. The more you push, the more torque it puts out. The less you push, the less torque. "

How complicated is this? I like the idea of a lowish speed motor as an assist. I don't know much about induction engines. Mostly what I read about is PM engines. Will have to research.

On the other hand, a hybrid with range extending ice may be possible? If I were to use the pm as primary drive motor while free wheeling the ICE (not sure I can fo that), drain battery, then run off ICE and while freewheel regen charge batteries.

What did you mean by 'cog'?

" Hi
after checking chain clearence yesturday its finally time to make some chips..
started with first piece - the motor-mount.
Snug fit as it should be.
Guess i will ad some lighting holes tomorrow- easy as perfect position is not critical...

" Finally made it to our second test session of the motorcycle. Made significant gains and we are now
knocking on the door of the 8 Second range in the Eighth Mile. Perfect for a bracket racing bike!
The motorcycle ran flawlessly with turn around times of 20 minutes. Still need gear change or two
( maxed at 4500 rpm) and still only running 67 volts. So I expect even more speed over the next month or two.

" Hi, thank you for your reply. Iím sorry for the confusion, but I have no intention of using any hub mounted setup for the motor. It will be mounted in the same location as the engine with the sprocket in the same place.

The hub motor which was mentioned was for a completely different project, a low cost electric three wheeler for mass production. "

" The Agni's are great motors, but I wouldn't even consider using one in a hub config if you're after 100MPH and race spec performance.
Suggest doing some reading up on 'unsprung mass' and its effect on the handling characteristics of a vehicle.

Long story short - *really* bad idea!

If you want that sort of performance, with any respectable measure of handling, you're going to have to keep the motor inboard.
The Agni's will do this, and that frame will fit it (high up in the rear is the usual location), but you'll need a transfer box to the bring the chain inline with the action of the swing arm. "
