3000w E-Bike Conversion Kit + 72v 20ah Battery

The number that matters is 80A, not 3000W. The motor is badged 3000W, which is about 42A at 72 volts. But the controller and the battery will both pass 80A — near enough 5760W in a burst. That headroom is where the 60mph comes from, and why this kit feels nothing like a 2000W build with a bigger battery bolted on.

Off the line it is violent in a way the 2000W kits are not. The shove arrives instantly, so the front wheel gets light if you are not deliberate with the throttle.

On hills nothing we sell touches it. There is no sag, no cut-out, no hunting for power on a long climb, because nothing in the chain is running near its limit.

Why 72V rather than a bigger 52V pack. Higher voltage means less current for the same power. 3000W at 72V draws 42A where the same output at 52V would need 58A — less heat in the controller, connectors and wiring. It is why serious builds go up in voltage rather than up in amps.

Range honestly. 20 to 30 miles on throttle alone. Ride it the way it wants to be ridden and it will be nearer 15. This is a power kit, not a distance kit.

Why people pick this one. A different animal entirely. 3000W on 72 volts, an 80A sinewave controller and an 80A BMS behind 80 Samsung cells — so nothing in the system chokes the motor.

• 3000W motor wheel — laced into a double-wall rim, built and trued
• 72V 20Ah Smart battery — 80 Samsung cells, 80A BMS, Bluetooth
• 80A sinewave controller with its bag
• M8 colour display — speed, battery, assist, trip
• Pedal assist sensor — magnet disc and pickup
• 2 x NFC cards
• Heavy duty torque arms — essential at this power
• Sur-Ron throttle + Pro Taper grips
• 84V charger — UK plug
• Rim tape
• Mounting hardware for the frame triangle

Tools you will need: two adjustable spanners, an Allen key set, scissors, and tyre levers if you have them.

The pack pairs with a free app on Android or iPhone and reports every cell voltage across all 20 groups plus the spread between them, charge level in volts and amp-hours, battery and MOSFET temperature, cycle count, remote charge and discharge cut-off, and live current draw.

Why it matters more on this kit. There is more energy in this pack and more going on inside it — 20 cell groups rather than 14. Being able to watch the spread between them, and see what the motor is actually pulling in amps, is worth having when you are running 80A.
