RE: Large packs... Check this out!!!
Ya, Killacycle is the only official electric motorcycle sponsored by A123. They wouldn't even talk to us about sponsor ship because we were still in the designing phase. Kent is hoping that breaking the speed record with his upright bike might pull enough weight to get him a second set of batteries for his streamliner project. For the streamliner he will basically double the system he has in the upright bike and shoot for nearly double the speed.
The Killacycle is a drag bike, all muscle, not really meant for high speed other than 1/4 mile runs. Kent's bike is shooting for records in the 2 mile runs... for the streamliner I believe it's about 5 miles they have to go.
