CYC X1 Pro Gen 4 eBike Motor Conversion Kit


CYC's most powerful motor just got an upgrade. Introducing the X1 Pro Gen 4.


The CYC X1 Pro is a powerhouse. New for 2024, it now includes the all new X12 controller, capable of producing up to 5000W of power and 280 N.m. torque. With double the capacity of the Gen 3's X6, the X12 controller can operate at up to 84V and 120A, delivering as much as 6kW of peak power. The motor has been redesigned for better thermal performance with a 25% larger core. The X1 Pro kit features the highest power to weight ratio in the eBIke market at 1.5kW per kg.


The X1 Pro builds on the success of the Gen 3, equipped with advanced torque sensing, responsive throttle capabilities, & customizable assistance tuning - on the fly and in the App. Feel one of the best pedal assist sensations in the ebike world with the integrated flywheel/torque sensor, providing pedal assistance that feels like a natural extension of your own effort.


The CYC X1 Pro eBike conversion kit comes complete with everything needed to convert your conventional bike to an eBike with the exception of a battery pack or required adapters. It 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 with a seperate button control module and has been upgraded to support battery packs operating at up to 72V. You can also choose between a universal thumb throttle, half-twist or a full twist grip throttle control.


The CYC X1 Pro offers the widest range of compatibility with mounting hardware and the most adaptive platform on the market for attachment to modern conventional bike frame designs. Bottom bracket options include BSA 67-83mm, 100mm, 120mm, and Press Fit BB92 (with threaded adapter). Most other bottom bracket types can be used with a BSA threaded adapter. Chainring options include 32T/53T, 38T/63T (standard), or 40T/72T. 175mm crankarms are included as standard with 165mm available by special order. 


The CYC X1 Pro eBike conversion kit comes complete with everything needed to convert your conventional bike to an eBike with the exception of a battery pack. The Pro is compatible with battery packs between 36V to 72V using a (battery side) XT90 female connector.


To reach maximum power output with the X1 Pro, match this motor kit with a high discharge battery pack such as the CYC B52L with Samsung 40T cells and 70A BMS. Using the X1 Pro at lower power outputs also has advantages, such as better range while operating at lower tempuratures. 


The CYCRide Control mobile App allows you to customize your CYC system with the mobile app (via Bluetooth) and the programmable controller with display menu integration.
