The CYC X1 Stealth is a compact and lightweight mid-drive motor and controller kit for converting your convensional bicycle into a powerful and capable eBike. It builds on the success of the third generation CYC X1 Pro with tuned control using a torque sensing bottom bracket to deliver pedal assistance that feels like a natural extention of your own effort.
The CYC X1 Stealth is a more compact and quieter package than the X1 Pro while still delivering up to 1500W of power and 150NM torque. Like the Pro, the motor/controller mounting hardware is the most adaptive platform on the market for attachment to modern conventional bike frame designs.
The CYC X1 Stealth is available with two display options. The SW102 Display is a small B&W screen with integrated controls and can be mounted on the right or left side. The DW103 display has a larger color screen which is typically mounted in the center and includes a seperate button control module that can be mounted to either right or left sides of the bars.
The CYC X1 Stealth eBike conversion kit comes complete with everything needed to convert your convensional bike to an eBike with the exception of a battery pack. The Stealth is compatible with battery packs between 36V to 52V using a XT90 female connector.
The CYC Motor X1 Stealth Gen 3 conversion kits come standard with adjustable 67-83mm Bottom Bracket, a B&W SW102 display, 38T/63T chainring freewheel assembly, 175mm crank arms, and universal (right/leflt side) thumb throttle.

3RD GENERATION UPDATES
X1 Pro and X1 Stealth Gen 3 had a design overhaul with the intention to provide not only the best power and torque, but also to provide a convenient solution. The redesign of CYC conversion kits also made it possible to solve previous weaknesses thanks to rider feedback.
ROTOR CORE & MOTOR
With mechanically retained magnets inside the CYC motors, they are designed to reach high RPMs without failing under heat stress.
CONTROLLER RELIABILITY AND PERFORMANCE UPDATES
The PAS and throttle experience are refined. The following list of issues are addressed with the X-series controller.
- High Initial torque
- Peak power
- Maximum reliability
- No cut-out with full power in bumpy terrainInstant throttle response
- Refined torque sensor tuning
- Simplified app
- Fully programmable via display, so using the app is not mandatory
TORQUE SENSOR TECHNOLOGY
New CYC motors are equipped with the Gen 3 torque sensing technology exclusively developed in-house by their team of engineers and riders. Together they achieve an unparalelled pedal assist riding experience.
NATURAL, SMOOTH RIDING
CYC's patent pending torque sensor includes both a high sensitivity strain gauge module and a cadence sensing module. The high number of poles of the cadence sensor ensures a hight degree of control and sensitivity and provides fine-tuning of the firmware by riders.
SEALED, INTEGRATED, & BUILT TO LAST
The new Gen 3 PAS (pedal assist system) is integrated with the robust sprag clutch module so there's no external wiring that can get caught, bent, or accidentally snapped. The CYC PAS operates with both the torque and cadence signal.
ISIS SPLINED CRANKSET
Ensuring you have a durable crankset is crucial to any ebike. The new integrated torque sensing module has made it possible for us to give you back the ISIS splined crankset so you can rest at ease knowing that no matter how hard you pedal, your crankset will stay secure. The bottom bracket bearings are now fully sealed to ensure maximum reliability with outdoor use.
All the previous water ingress point has been sealed properly with the upgrades. All the exposed bearings are also sealed so the systems are now safe to wash and use under heavy rain condition.
2-year warranty starts on day of delivery. Man made failures and use of this product with a system not supplied by CYCMotor Ltd will not be supported or warrantied.
