Hi,
I just recently read about this (A123) lithium battery powered electric motorcycle, and it looks freakin' awesome!

Voltage: Nominal 53 V, fully charged 60 V
Weight battery pack: 48 kg (106 lbs)
Capacity: nominal about 4.8 kWh
Total weight: about 165 kg (363 lbs)
Top speed: The bike is geared for 100 km/h (60 mph) at the moment. Because it has a PMDC (permanent magnet direct current) motor, max RPM is decided by the voltage (this is characteristic for PMDC motors). With a PMDC motor, you therefore have to choose acceleration or top speed. There is enough power for higher top speed, but because it bike is slightly under-motorized, gearing for a higher top speed would cost too much acceleration and also give lower efficiency. 100 km/h is an acceptable compromise at the moment.
A new battery pack with higher voltage is waiting to be installed. The new battery pack will hopefully give a top speed of 100 mph.
Range: About 80 km (50 miles) per charge at 70 km/h (44 mph).
