75lbs or less, 8-10kw with the current drivetrain, 20ah @48v, 8+ inches of travel at both ends, fat tires, on the fly adjustable geometry and seat height, all belt drives, nuvinci in frame, hammerschmidt. PM me if you want give me a bunch of money.
Back to your regularly scheduled programming.
I'm sorry things did not go your way, but maybe some day you will have a high quality product that people will pay premium for. I hope that day will come when batteries and controllers are solid and cheap.
For now I just play around with whats available.
I just want to ask how you would make it that lightweight with todays technology?
I've played around with some numbers, and thats a hard weight to beat.
Lets take a high end Specialized Demo 8, it weighs 17-18kg.
12s 20Ah lipo, Turnigy nanotech 6s 5Ah, 800g per brick. Eight needed, 6,4kg http://www.hobbyking.com/hobbyking/stor ... _Pack.html
The lightest controller would be a hv 160, thats 210g
I don't know about a suitable motor for 8-10Kw, but lets say a 80-100. Thats 1,5kg, you wont find any lighter motor capable of 8-10Kw(This one is not, so I would guess that you will need a bigger heavier motor. Copper and steel weighs a lot)
Misc hardware as chains, sprockets etc: 4kg.
Total: 29-30kg or 66lbs
But then you don't have any mounts, just a bare frame. I don't know if it is feasible or not. If I had the money I would like to give them to you so I could see what you could create.
