Was browsing craigslist just now and came across a posting from Thunderstruck referencing:
a new all electric off-road motorcycle custom built by ThunderStruck Motors. The 'Road Runner' has an all aluminum frame with front and rear disc brakes. It is available in three power configurations : 24 volt; 36 volt; and 48 volt. A powerful Etek motor, Alltrax controller, Magura twist throttle, and your choice of knobby or road tires are standard. An aluminum battery box is positioned for maximum performance and an ultra-slim profile. Advanced engineering makes chain tensioners a thing of the past. Sealed lead batteries are included, however, lightweight, high performance LiFep04 (lithium) batteries are available for $1,000,(48 volt. 36 & 24 volt systems are less). Estimated range is about 15 miles at 30mph. Top speeds: 48volt= 42mph; 36volt= 30mph; 24volt=20mph, with flexibility in range and speed through custom gearing. These enviromentally friendly dirt bikes are quick and they can really climb! Great for camping, out on the ranch, and off-road fun without scaring the animals away.
Range: 15 - 40 miles
Top Speed: 20-45 mph
Charge Time: 3 - 4 hours
Controller: Alltrax 4834

Seems like a pretty good deal considering the 48v version will do 40 mph. I like that small frame.
