The CYC Photon Gen 2 is the mid-drive motor for riders who want serious performance without the full-send power of the X1 Pro. With 2000W peak output, 135 N.m of torque, and a revolutionary inrunner motor design that runs 60% cooler than the competition, the Photon Gen 2 delivers smooth, natural, trail-proven power in a compact, serviceable package. Trail riding, climbing, commuting — it handles all of it.
Why the Photon Gen 2 Stands Apart
Inrunner Motor Core — 60% Less Heat
The Photon Gen 2 uses a revolutionary inrunner motor design that generates up to 60% less heat than conventional mid-drives. Less heat means better sustained performance, longer motor life, and no thermal throttling when you push hard on a climb.
2000W Peak / 135 N.m Torque
The Photon Gen 2 hits 2000W peak in unrestricted mode with 135 N.m of torque at the crank. That is more than enough for steep technical climbs, loaded commuting, or spirited trail riding — while staying manageable and natural-feeling for everyday use.
Patented Torque Sensing
CYC's torque sensing technology reads your pedal input and scales assist seamlessly — no on/off surge, no dead spots. It feels like a natural extension of your riding, not a motor switching on and off.
Helical Gear Drive
Helical gears run quieter and smoother than straight-cut alternatives. The Photon Gen 2 is noticeably quieter on the trail than most mid-drives — you hear the ride, not the motor.
Sprag Clutch — 3x the Load Rating
The upgraded internal sprag clutch is rated for 3 times the load of the Gen 1 Photon. Instant engagement, zero drag when you are just pedalling, and built to last under serious use.
Modular and Serviceable
The Photon Gen 2 is designed to be serviced and maintained — not thrown away. Modular construction means individual components can be replaced without sourcing a whole new motor.
Fits 95% of Frames
Multiple bottom bracket standards and a wide chainring selection mean the Photon Gen 2 installs on almost any bike you own.

Frequently Asked Questions
Is this the motor only or a full kit?
This listing includes the complete conversion kit — motor, controller, display, cranks, chainring, harness, sensors, and all hardware. Battery is sold separately.
How does it compare to the X1 Pro Gen 4?
The Photon Gen 2 is the more versatile, natural-feeling motor — better suited for trail riding, commuting, and builds where efficiency and ride feel matter. The X1 Pro Gen 4 is for riders who need maximum raw power. Both are exceptional motors for very different purposes.
Will it fit my frame?
The Photon Gen 2 supports multiple bottom bracket standards and fits 95%+ of frames. Not sure? Reach out before ordering and we will confirm fitment for your specific bike.
What battery should I pair with it?
The A-52L is the most popular pairing for Photon Gen 2 builds — great balance of range and weight. For maximum range, the A-65 is the top pick. Reach out and we will help match the right battery to your riding style.
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.
