Benchmark: Biggar’s e-fighter

Text from his site are as follows:

In this video I build a custom electric streetfighter motorcycle. Plans for this project are available at the following link: https://www.resystech.com/electric-st…

Though equivalent to most 300cc street bikes in overall power, this little monster boasts a massive 250 ft-lb of max starting torque and over 100 ft-lb of mid-range torque, and only weighs 300 lbs. Top speed is limited to 115-150 kph depending on the system voltage, but it boasts more torque than most 1000cc bikes to produce white knuckle acceleration at legal speeds, so you can still have fun without the risk of getting a speeding ticket, or worse. In fact, unless you’re a pro rider with great throttle control on one wheel then you’ll probably want to use the controller program to lower the torque to 25-50% for the first few rides.
