2000W Rear Hub Motor E-Bike Conversion Kit MTX

At 2000W, torque and speed move up to another level. The motor delivers up to 80 N·m straight into the wheel hub and reaches 72 km/h with the right battery, while the 45A controller accepts any voltage between 48V and 72V. The gearless direct-drive construction has no gears and no brushes, so it sustains this level of load without mechanical wear.

2000W technical specifications

Torque and speed at 2000W

The 2000W kit gives you 80 N·m of torque, 60% more than the 1500W, and speeds of up to 72 km/h at 72V. The 45A controller sustains that torque for long periods, not just in acceleration peaks.

It feels best when pulling away under a heavy load, on long steep climbs and at sustained speed. For less power, 1000W and 1500W are the intermediate steps in the range.

Why the torque arm is mandatory at 2000W

At 80 N·m, the torque transmitted through the wheel axle far exceeds what a bicycle dropout can carry, whether steel or aluminium. Without extra fixing, the axle starts turning in its seat – the phenomenon known as a spun axle – widening the dropout and destroying the frame, often within a few weeks of high-load use.

That is why both torque arms come included in the kit, not sold separately, and they must be fitted on both sides of the axle. Fitting takes 10–15 minutes per side and needs no special tools. At this power it is not a recommendation but a condition of operation.

45A controller, with the voltage of your choice

The controller accepts 48V, 52V, 60V and 72V with no modification, which means you can start with a 48V battery and move up to 72V later for maximum speed and torque, keeping the same kit. It normally works with the motor's Hall sensors, and if a sensor fails it switches automatically to non-Hall mode. The brake levers cut power to the motor instantly.

What the 2000W kit does best

Choosing the battery

The kit ships without a battery. When ordering you can add one of the batteries below, chosen for this kit, all with a key lock and charger included. You can see more in the e-bike batteries category.

2000W or 3000W? When it is worth going up

2000W covers almost any need for torque and speed. If you want even more torque, a 60A controller and better efficiency on sustained climbs, the 3000W kit is the top step in the range. Bear in mind that at that level the battery becomes the most expensive component of the project.

Warranty and spare parts

The motor carries a 24-month warranty and the electronic components 12 months. Spare parts and accessories are available in the eBike parts section. Compare every power option in the conversion kits category, from 250W up to 3000W.
