The CYC X1 Pro Gen 4 is one of the most powerful mid-drive conversion motors on the planet. 5000W continuous, 6500W peak, 280 N.m of torque — this kit turns virtually any bike into a machine that can handle extreme trails, heavy cargo, or full-power commuting domination. If you want the most capable eBike conversion system available, this is it.
What Makes the X1 Pro Gen 4 a Beast
5000W Continuous / 6500W Peak Power
Most mid-drives tap out at 250-750W. The X1 Pro Gen 4 starts there. With 5000W continuous and up to 6500W burst through the X12 controller, this motor outperforms almost every other mid-drive on the market — full stop.
280 N.m Peak Torque
That is not a typo. 280 Newton-metres of torque at the crank means you are climbing grades that stop other eBikes cold, hauling cargo loads that would smoke a lesser motor, and accelerating off the line faster than most people expect from a bicycle.
Gen 4 ISIS Torque Sensor
The new ISIS-splined torque sensing system reads your pedal input in real time for natural, responsive assist that scales with how hard you push. No lag, no guessing — just smooth power on demand.
25% Longer Motor Core
The Gen 4 redesign added a 25% longer motor core with improved thermal efficiency — translating to better sustained power output and longer motor life under hard use. At 1.5 kW per kilogram, the power-to-weight ratio is exceptional.
X12 Controller — 84V / 120A
The included X12 controller handles 84V and 120A continuous, supporting peak outputs up to 6kW. Street-legal PAS mode or full unrestricted power — switchable via the display or CYC Ride Control app.
Fits 95% of Frames
Multiple bottom bracket standards supported (BSA 68-83mm, BB92, BSA 100mm, BSA 120mm) and multiple chainring sizes (32T, 38T, 40T) mean the X1 Pro Gen 4 fits almost every bike on the market.

Frequently Asked Questions
Is this the motor only or a full kit?
This listing includes the complete conversion kit — motor, controller, display, torque sensor, cranks, chainring, harness, throttle, sensors, and all hardware. Battery is sold separately.
Which battery do you recommend for the X1 Pro Gen 4?
We recommend the A-65 for maximum performance and range. The A-52L is a solid choice for builds where weight or frame space is a concern. Reach out and we will help you match the right battery to your build.
Will it fit my frame?
The X1 Pro Gen 4 is compatible with 95%+ of frames across multiple bottom bracket standards. Not sure about yours? Reach out before ordering and we will confirm fitment.
Can it run in street-legal mode?
Yes. The X12 controller and display support switchable power modes from street-legal PAS to full unrestricted power via the CYC Ride Control app.
Is this available in Canada?
Yes — Power in Motion is Canada's premier authorized CYC distributor. You are buying from a dedicated CYC specialist with full warranty support.
Building something specific — cargo bike, fat bike, trail ripper? We are here to help — reach out before you order and we will make sure you get exactly the right setup.
