Honestly for $8K, I'd rather fabricate something and get better performance. I don't count my labor when it comes to stuff like this.What about ems's GPR-S? I think you could get Empulse performance for much less. There is a 09 left over stock in the "opportunity buys" section for $3500 that only needs batteries. Even if you go with their 72v 100ah lithium battery kit you are only adding ~$4500. Should be close to Empulse performance at a fraction of the cost, and better yet, you don't have to wait to buy it.
At what speeds? Exponential wind resistance is a bitch.energy consumption per mile..
Agni motored Aprilia sportsbike, 130kg. best 70wh/m worst 145 wh/m
Dual Agni motored TTX02 175kg. Best 100 wh/m worst 300wh/m (well, it is a race bike)

I've been looking for info on the consumption of an aerodynamic electric bike at highway speeds for a while.
The E-Tracer (electric Ecomobile / Monotracer) electric cabin bike got 123 watt hours per mile from LA to Vegas - http://peraves.wordpress.com/2010/11/01/e-tracer-at-sema-show-in-las-vegas/
Quite possibly not what patracy is looking for, though.
Oh, yeah, the ICE Monotracer is crazy expensive, something like $77,000. I'm sure the E-Tracer with all the lithium ion, and A/C motor and controller, will be even more so. And I believe that's with kevlar, not carbon fiber. Uses a BMW K1200S engine.It certainly would be interesting. But seeing the design and all that CF makes me think $$$$$$
That's not very useful. For all I know, what "real world" means to you is wondering around at 20mph with no stops.They were min and max figures obtained from real world experience with a number of bikes, not hyperthetical figures of power draw cruising at a fixed speed.
Since it hasn't been said yet: Regen doesn't seem to be very helpful.I'm kicking around the notion of either a EV car or bike. I need a bike to be able to do 60mph and 50 miles. What would it take to build something like this in a bike? I assume regen would certainly be needed.
Jozzer has had a big hand in building and maintaining the TTXGP bikes. He may have been limited to 20 mph in the pits, but the rest of the time the average speeds were a little faster than that.That's not very useful.
