The best the bike has done was 62 mph. Realistically it does 40 mph without completely destroying battery life. The 900 watt bulk charger works great and I am balancing using a RC charger. The $230 Turnigy battery pack has last 1,500 miles which is absolutely astonishing to me.
NEXT BIKE! This is an early design concept teaser pic. The frame will be possible thanks to Cartesian CNC profiling and bending http://www.cartesiantube.com/

Wheel with Spokes! This is the first wheel I've ever laced, fun job! I recommend everyone do their own wheels.

Going to make a swing arm from 5"x2" 0.125" wall aluminum.
I am approaching my design freeze within the next 2 weeks. Unfortunately I had to wait until the nuvinci dev kit got here to make measurements for the custom dropouts/NV servo mount.
The batteries will be 12s Turnigy li-po mounted in the swing arm tubes. Balancing/monitoring will be done by 2 resistor modded cell medics. The controller is a Kelly kbl48201 100/200amp I will be running Burtie's linear optical sensors.
There will be no pedals. In Georgia mopeds/scooters don't require pedals or registration
but are completely street legal any where except highways.
