E-bike retrofit motor CYC X1 PRO EXTREME!
Discover the ultimate in e-bike power with the new 4th generation CYC X1 PRO. This powerful motor with an impressive 5000W output was specially developed for very demanding bikers. Experience the freedom of riding off the beaten track through the terrain.

Features:
- 5000W power
- 280 Nm max. Torque
- New X12 controller
- Compatible with 36-72V batteries
- 32T, 38T and 40T chainring options
- Fits bottom bracket widths from 68-120mm
The biggest innovation compared to the previous Gen3 version is the new and powerful X12 controller. The following improvements have also been made:
- Robust Gen4 torque sensor
- New rotor for higher speed
- 25% longer motor for increased efficiency and better heat dissipation
- Simplified chain tensioner
In this blog, we have taken a closer look at the upgrades.

The CYC X1 Pro Gen4 motor is available for the following bottom brackets (select above):
- BSA 68-83 mm
- BB92 mm (incl. adapter)
- BSA 100 mm
- BSA 120 mm
Included in addition to the motor:
- X12 Controller
- Fastening set
- Axle sleeve and axle
- Speed sensor
- Main wiring harness
- Spacer
The X12 controller is connected to the smartphone via Bluetooth. After installing the new CYC Motor App, you can adjust the motor parameters conveniently and without cables. The download area contains numerous useful links and downloads (installation, operating instructions, printouts, etc.).
Controller:
The new X12 controller is much more powerful than the X6 controller. It also allows the use of 20S batteries (72V nominal voltage). We have compared the two controllers in the following table:
| X6 Controller | X12 Controller | |
|---|---|---|
| Nominale Spannung | 36-52V | 36-72V |
| Peak Phase Current | 110A | 180A |
| Peak Battery Current | 65A | 100A |
| IP Schutzklasse | IP66 | IP66 |
| Display Kompatibiliät | SW102, DS103 | SW102 (bis 52V), DS103 |
| CYC Kompatibilität | X1 Pro Gen2 & 3, X1 Stealth Gen1 & 3 | X1 Pro Gen4 |

Smartphone App:
With the new X-Controllers, you can unleash the full potential of the CYC motor: instant torque and power, stable off-road performance, responsive throttle response and refined pedal assistance. With the CYC Ride Control smartphone app (available in the App and Playstore), you have all the options at your fingertips. Simply pair your smartphone with the controller via Bluetooth and you have the freedom to ride the way you want.
A 72V (20S) battery should be used in order to utilize the maximum power. It is essential to ensure that the battery is sufficiently designed. The CYC X1 Pro Gen4 can also be operated with the 14S batteries available from us and thus with 58.8V – the maximum output here is approx. 2000W. We recommend that you use batteries with a high discharge current rate for the individual cells (e.g. Samsung 30Q or Sony VTC) so that the required amperes can be drawn from the battery. You are welcome to contact us – we can also manufacture a battery according to your specifications (up to 52V/14S). If you need a 20S/72V battery, simply contact a battery manufacturer directly.

Unglaublich kraftvoller Motor, hab mir dafür extra ein neues Cube-Bike gekauft. Nutze aber nicht die volle Power, das hält doch kein Bike aus. *lol*

It´s a really powerful motor – throttle needs to be used with finesse. Love it *smile*

The app is just awesome. Where else can you adjust your e-bike via smartphone – from power to motor responsiveness? Even though many won’t believe it, I actually use Street Mode to ride legally on the road. And off-road, I switch to Race Mode for full power. Amazing development, guys.
