CYC X1 Stealth Gen3
The CYC X1 Stealth Gen 3 mid-drive motor is a high-end/high-performance ebike conversion system that is the creation of CYC Motors in Hong Kong. These guys know what they are doing. They created this bad boy as the stealthy baby brother of the X1 Pro, but it is still one of the most powerful motors available.
This motor preserves a perfect chain line on any bike and tucks up high off the ground, even on modern mountain bikes with a curved downtube. 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 motor is versatile, fitting 95% of frame types, including carbon frames. It can be set up as a class 1, class 2, or class 3 ebike from 350 to 750 watts. Off-road modes go from 750-2,000 watts (depending on battery).
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 lights powered from the main battery, you may want to consider the CYC or EBC high-power light sets. They both have a handlebar mounted switch to turn the headlight on and off. The CYC headlights have two separate lights that each mount directly on the handlebars. The EBC Headlight includes low-beam with horizon cutoff, high-beam, and running lights and mounts on the front stem bolts freeing up handlebar space and not interfering with the ebike display. Both lights are brighter than most car headlights.
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 just change them out when they start to slip.
NOTE: Electrify Bike Co. does the final assembly of CYC motor kits in the USA and we ship to all locations in North America. We do not ship to China and Hong Kong.
