Electric assist motorized bicycle using an old 1990’s vintage Huffy and an ElectricRider (www.electricrider.com) Crystalyte Phoenix Cruiser 7240 – 5304 front hub motor with 7240 controller, 72 volts from 6 12 volt SLA batteries. The kit had everything to turn my clunker bicycle into a scary fast (42 – 44MPH) and powerful bike. It does some cool burnouts too. What a fun bike!
