A complete electric conversion pack built around a 72V 5000W gearless rear hub motor, a 72V 100A Sabvoton sine-wave controller and a 72V 30Ah hard-case battery using Samsung 50S cells. It is aimed at experienced builders who want very high power and speed from a custom bike, with a claimed top speed near 60 mph and 50-65 miles of range. The rear dropout is 150mm, so it fits only frames with that spacing and vertical dropouts. Compared with typical 48V or 1000-1500W kits, it delivers far more torque and speed but is heavier, more demanding to install and not a beginner setup.

The high torque and power suit experienced riders who are comfortable with fast acceleration and powerful electric assistance.
