CYC X1 STEALTH Gen3 E-Bike Conversion Motor!

As with the big brother X1 PRO, the BAC 855 controller has been replaced by the CYC X6 controller. In addition, the torque sensor has been improved and the installation simplified. The new CYC smartphone app is also very nice: the setting options have been reduced to the essential components, visually better prepared and also equipped with movable bars (instead of lots of editable values).

This product includes only motor, controller, wiring harness, speedsensor, mounting parts and ISIS axle.

Features of new Gen3:

  • New X6 controller
  • Torque sensor renewed, ISIS axle
  • New smartphone app
  • New displays DS 103 and SW102
  • New speed sensor and magnet
  • Simple, improved motor mounting

The manufacturer recommends running the system with max. 14S (52V) batteries. Even tough it is the same controller as for X1 PRO motor and thus you could use it also with 72V batteries, the efficiency is better at lower voltages ensuring that pre-mature-wear cannot occur. The motor was designed to run best at 36V to 52V. If the motor ist operated with more than 52V (14S) batteries, the warranty claim is void!

CYC X1 Stealth Gen3 Motor is available for these bottom brackets:

  • BSA 68-83 mm
  • BB92 (BSA 100 mm version with incl. adapter)

The following items are included:

  • X6 Controller (up to 52V)
  • ISIS axle
  • Fixing parts
  • Speed sensor and magnet
  • Wiring harness
  • Spacers

The new X6 Controller can be connected to your smartphone by using bluetooth. After installing the new CYC App the motor settings can be changed to your preference without using a cable. In our DOWNLOAD area you can find lots of useful links and downloads (installation, user manuals, printout, ...).


The new controller is one of the most significant updates for the new generation. The X-Controller Series is designed for you with in-house firmware giving way to optimized pedal assist and throttle experience.

Torque Sensor:

The CYC PAS runs with both the torque and cadence signal collected and is processed by the new controller to provide you with a pedal assist feeling like never before.


Smartphone App:

Instant torque and power, stable off road performance, responsive throttle, refined pedal assist experience - the x-series controllers are the key components to power all CYC motor systems. Introducing the CYC Ride Control mobile app, aimed to unleash all the possibilities at your fingertips. Experience an advanced settings selection and an on-the-go mode on the horizon.

Customer evaluation for "1500W E-Bike Motor CYC X1 STEALTH Gen3"

Too much parts, only problems, not reliable

I definitely don´t recommend this motor. because you will only have problems. The whole system isn´t reliable. I didn´t buy from fasterbikes, but they still tried to help me with this s****. On their recommendation, I have now purchased the new photon motor. This one is really good and reliable.

Powerful but some problems

Nice quality, really powerful, easy installation - but I had only a few rides without errors shown on display. Some of them appear only briefly and seem to have no effect. But I hate error 30. This should be fixed by manufacturer. Thank you fasterbikes for your patient help.

Klein und fein

schöne optik, saubere kettenlinie, einfache montage und ausreichend bodenfreiheit - so würde ich diesen motor beschreiben. 1 stern abzug da er noch ein wenig leiser sein könnte, aber ansonsten top.
