Lightning Pie by TorqueX — 3000W Rear Hub Motor Conversion Kit (72V)

Skip the bottom bracket teardown. The Lightning Pie by TorqueX rear hub kit turns your bike into a dirt-bike-quick ride in an afternoon — pull the wheel, drop this one in, and go. We've built and ridden one ourselves — it delivers Sur-Ron-level torque without the mid-drive install or the price tag. Why buy a Sur-Ron when you can build this much power for a fraction of the cost? 3000 watts is serious output — this isn't a "fits a bike lane" kit, it's a genuine high-speed conversion for riders who want real acceleration and top end. No chainring swaps, no bottom bracket compatibility puzzle, no chain wear from cranking watts through your pedals. Just a beefed-up rear wheel, a real controller, and a throttle that means business. Fitment: Compatible with tire widths from 2" to 3" — fits standard 135mm dropout frames. What's in the box: 3000W gearless hub motor, 135mm dropout 72V 60A aluminum controller SW900 display Twist throttle AND thumb throttle (use whichever you like) 12-magnet pedal assist sensor Single-speed freewheel Controller storage bag Battery (sold separately): Runs on 72V only.
