CYC Photon

The CYC Photon mid-drive motor is a high-end/high-performance ebike conversion system that is the creation of CYC Motors in Hong Kong. The CYC Photon represents cutting-edge, state-of-the-art DIY mid-drive motors.  The Photon sets the bar higher than it has ever been for DIY and factory mid-drive motors.  It has a finely tuned response to meet the demands of the most discriminating cyclist or MTBer. On top of that, it sets a new precedent for power and quietness in a lightweight motor kit. 

This motor preserves a perfect chain line on any bike and great ground clearance With its torque sensing and cadence sensing bottom bracket, it delivers power at the cadence you choose and senses when you crank up your effort and delivers more power on demand.

This versatile motor fits most frame types, including fat bikes and some carbon frames. It can be set up as a class 1, class 2, or class 3 ebike from 250 to 750 watts. Off-road modes go from 750 to over 1,000 watts.

It comes with everything you need except the battery, and we have those in 52v and 72v at 50 amps and from 300-watt hours to over 1000-watt-hours.

For a great 1x drivetrain, the ebike-rated Box Two and Box Three drivetrains are durable and affordable. With all the power this motor can deliver, you will still wear out the higher (smaller) gears on the rear sprocket. Fortunately, Electrify Bike Co. has arranged with Box to sell these as a set of 4 sprockets for just $20, so you can change them out when they start to slip.
