Thanks... I'm very excited. I am doing the first field test this Saturday evening. I'm going to do it in the dark to maintain secrecy.

I'm a little concerned about the batteries though. I'm not sure that the battery fluid won't spill out on the 24% grade hill climb I am going to test on.

The 2 watts of extra power though should have the same effect as spending an extra $1000 on super light wheels. I should also be able to stay in the big chainring as a result of the power boost.

Well, I've got a design for a conversion kit to plant a Hayabusa motor to your bike for the same purpose of aiding hill climbs. Its amazing how a 160hp motor aids in those steep hills, There have been a couple of drawbacks, it adds 432lbs to the bike, the crank has to be widdened to clear the motor, for some reason the bikes stock chain won't hold up, gas mileage is only in the upper 30mpg range, BUT it will do 194mph.....of course finding 700C tires that are speed rated has proven to be a challenge.

Rather than carry those heavy batteries, use a front hub generator to power the motor.

OMG that's brilliant. I hadn't considered the weight of the batteries as having much effect. I think it will be a negligible negative drag on the climbs compared to the 2W power boost though.

The front hub dynamo is a great idea however. In fact I will probably add that to the set-up in any case to recharge the batteries while riding. It could be a perpetual motion system, requiring little, if any pedalling on the flats...

Forget it. Just ride Cheng Shins, they will hold up fine at those speeds. May I suggest that you use wheels with at least 32 spokes?

Cool, I didn't realize they were rated for 200+mph and I hope the 32 spokers handle the 170hp, of course the NOS will kick it up to 240hp.

If you're gonna use NOS, then you're gonna have to have the 32-spokers re-laced radially. Roadmaster spokes are perfect for this.
