CYC X1 Pro Gen 4 Mid Drive E-Bike Conversion Kit

CYC X1 PRO GEN 4 DIY MIDDRIVE E-BIKE KIT

The CYC X1 Pro Gen 4 5000W Mid-Drive E-Bike Conversion Kit is one of the most powerful on the market, ideal for off-road and recreational riders tackling steep hills and rugged terrain. It fits most standard bicycles, including modern (e.g. BB92), old-school, and fat-tyre bikes.

Unlike in-wheel or hub motors, the mid-drive design uses your bike’s gears for massive torque while keeping weight low and centred for better handling. Its high-clearance design is perfect for rugged terrain and downhill riding. The kit pairs with any 36V–72V battery capable of delivering 80A continuous power, with peak performance at 72V. A Battery is not included and must be purchased separately.

• 1 x Crank Set - Left and Right

DESCRIPTION

Mid-drive kits offer a major advantage with reduced unsprung mass, making rugged terrain, off-road riding, and jumps easier and more enjoyable without risking damage to your bike or wheels. The CYC X1 Pro Gen 4 is one of the best kits available, offering a level of refinement rarely seen in the market. Designed in Hong Kong, it features torque sensing for a seamless riding experience, while still allowing full power access anytime with a twist of the throttle. It can be supplied with either a full-twist (motorbike style) or thumb throttle for ease of use.

Once installed, the X1 Pro tucks neatly behind your cranks at the bottom bracket, creating a clean, discreet, yet incredibly powerful setup. It pairs with any 36V–72V E-bike battery, though 72V is recommended for maximum fun. Battery is sold separately and must support 80A continuous output (not just peak). Please ask us if you're unsure about the difference between a battery’s 'A' (amperage output) and 'Ah' (amp-hour capacity).

WARRANTY

• General Wear and Tear is not covered by warranty.
• A common topic with mid-drive kits is the need for regular maintenance of your chain and drivetrain. Ensure your chain is properly aligned during installation, and regularly check, lubricate, and replace it as needed. Also, inspect your rear cogs to ensure they’re intact and free from shark-fin wear. Wear and tear, such as chain drops, chain stretching, and worn gears, is not covered by warranty and should be maintained by the customer. We recommend carrying a spare chain and quick link on every ride to avoid being stranded.
• Damages occurring due to incorrect fitment are not covered by warranty. Please contact us in case of being unsure of the correct installation or operation of the kit beforehand.
• Please take care to properly fit and protect the wiring coming out from the motor/controller assembly as this can be damaged if left exposed near the chain or bottom of the bike during off-road riding. This type of wiring damage is not covered by warranty.
• If using the bike in full power mode, it is highly recommended to be familiar with your local State laws and regulations. The use of the kit is your responsibility.
• The kit is not waterproof and therefore should not be immersed in water.
• Although this kit is renowned for being well designed and long-lasting, damages occurring from incorrect use of the kit is not covered by warranty. The kit is not suitable for impacts with logs, rocks or other objects or exceeding the recommended weight limit.

NOTES

• Australian regulations require that the kit does not exceed 250W continuous power and 25 km/h on public roads and paths. Please ensure the display settings are adjusted to 25 km/h in these circumstances. Settings can be accessed via the CYC phone app. Feel free to contact us if you are unsure.
