Build Quality & Upgrades Explained

Things keep changing? Yes! CYC Motor Ltd was hard at work in 2020 to improve the X1 PRO thanks to the support from our customers and the CYC Owners Group. We take pride in continuous development as we reach closer to our goal of bringing you the most powerful mid-drive motor with the smallest form-factor available in the market.
We understand it’s hard to keep track, so we decided to simplify things with a walk through all things new and all things fixed since the very first release of the X1 PRO mid-drive motor in 2019.
Let’s take it to the start of the Gen2. What’s different from the Gen1?
A New Motor Core & Rotor
From 6.5k RPM and 3k Watts, the Gen2 motor core and rotor were redesigned to give you even more BANG for your buck and is now capable of reaching up to 5,4k Watts at peak power with 12k motor RPM. This means that you can harness the power output much quicker.
Not only is the Gen2 more powerful, but it upgraded to waterproof Julet connectors and waterproof cable shielding. At last, you can take the X1 PRO out for a muddy spin without the worry of water damage. It’s still important to keep in mind that the motor is not made to be submerged, but it can handle a good, rainy day mission.
Without adding more weight to the kit, CYC kept the kit at an astonishing 5kg. The Gen2 is still light weight but it’s not just the small form factor that makes this motor stand out. The maximum power capabilities of X1 PRO are measured at 5,4kW and 264N.m of maximum rated torque with a 72V battery! To make this even more exciting, the motor system is highly efficient. With an efficiency rate of up to 93%, you are able to get much more range and carry smaller batteries.
At 5kW and throttle mode you are to ride your e-bike like a strong electric dirt bike. The lightweight system still enables extreme power and torque output. The Gen1 had a rated torque of up to 4 N.m. and the Gen2, up to 5 N.m. If you use a strong downhill bike with the X1 PRO, it will be a very capable of handling off-road missions.
All this with the added benefit of your e-bike still looking like a typical e-MTB after conversion, allowing you to enter most of the trails without a hassle.
Upgraded Components
Aside from the motor core and rotor, the gearbox, electronics, sensors, freewheel and sprocket all got an upgrade. Let’s start with the gearbox. With a more refined machining profile, the gearbox noise was reduced by 50%. Even though the new noise level is highly acceptable, we are still doing tests to improve this as much as possible.
On the Gen1, some electronics and sensors were located externally on the builds which led to easy damage. This concern was completely cancelled out with the Gen2 where all the parts are built in and internalized for a more reliable parts system. But the upgrades don’t end here…

The freewheel and sprocket was redesigned as well. The freewheel’s revamp included an increase in the number of teeth ensuring that the pedaling engagement is more direct and much faster. The sprocket got more reliable as well, changing from hardened steel to stainless steel which was more capable of handling extreme power and increases reliability. A 12T sprocket option was also added in the 72T chainring option whereas previously, all chainring options only had 11T at the sprocket.
When it comes to looks, the Gen2 comes with a stylish steel bash guard for the BAC855 controller as well as an Aluminium chainguard as opposed to the older carbon cover. The crank arms were upgraded with lightweight CNC Aluminium, not only making it look better but also shedding some weight. The new bash guard, chain guard and crank arms gives the rider an even sleeker e-bike look with a motor that will catch the eye of any en
