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. These guys know what they are doing. They created this Torque monster 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.
