Congrats my friend! You made it!

Interest is growing in the possibilities of streamlining and fuel economy. The Hall of Fame tent was filled. I invited electric pioneers Kraig Schultz, Matthew Childress, Randy Reisinger, Bryan Wilcox and Wolfgang Moeschei of Germany (fresh from X Prize prelims) to interact with traditional motorcyclists. We learned... they learned. The AMA provided display room for their machines. Additionally, they were able to take a lap around the Mid Ohio Raceway. It was a great weekend for all.
Note Craigs comment below:
My goal is to allow real streamlining on the race tracks so that less energy will be required. Azhar Hussain, rt, founder of the TTXGP, Jeremy Burnes and I discuss ways to incorporate real streamlining into the new electric motorcycle racing. With real streamlining, electric bikes will go farther on a charge

If you bring a 1000 watt bike to the death race, you'll be slow like I was last year. But still plenty fast enough to have a huge fun time on that kart track. Not having a curb or a parked car looming around that corner is really great! And you will still be faster than the more or less stock chinese motor kit bikes.
John in CR said:Did we ever get a distance for these races? Here's my bike at 49lbs along with my rider soon to start training, who probably won't be ready till the 2012 racing at Luke's place. The bike is missing some small parts in the pic, as well as the controller and battery pack, but there's some weight loss to come that will more than offset the missing odds and ends, like getting rid of the solid steel seatpost required for me to ride and cutting off the drum brake (regen braking on the rear). I just need to know range required to determine a pack.
I realize the little guy will be low on race experience, but that hubby pushes me to 60mph on 74V nominal, so even with a 50% weight gain by race day he'll still weigh considerably less than the bike. That will give him a tremendous power to weight ratio advantage over the rest of the field, and much lower total energy requirement. That means the race instructions can be just follow the leader and blow by him on the last straight away for the win. Max learns quick, so that will only be needed in the first heat, and he'll know his limits and can just say bye-bye from the start in subsequent races.
edit- Not only will this be the quickest bike in the field, it will probably be the cheapest too at less than $250 all up plus battery with the only used part being the bike frame.
I can't wait to get another bike together for this. I just got another bmx given to me. I have a 7kw rc kit coming from marko and If needed I will uses my 12kw motor! I will have a killer rig come hell or hi water! And I can ride! I am super stoked I lost 10 lbs aready for this my self and I will do what ever it takes to loose more weight to KICK SOME ASS!John in CR said:Dogman,
I wouldn't want to race it myself either, but for Max it would be like a 650cc gas dirtbike would be for me. I wish I only weighed 50lbs and could take it for a spin off road on the hill near the house where the dirtbikes go play.
Dozentrio,
I doubt I'd let my son race that young, the speeds would be too high. I just wanted to make a point regarding anyone actually taking the 70lb ebike racing seriously. I understand having the weight limit to keep costs and power limited, but if that's the only rule, then it's more about the size of the rider than anything else, because of the ability to manipulate the power to weight ratio via the rider. Same weight bikes and similar weight rider and bike combos, and then you'd have something to prove a better rig and/or rider.

The race should be long enough to make a good race, but not so long to require massive amounts of batteries. Say 12.5 miles / 20 km.

this is about the distance of the death race also.
