Cyplore has created what it says is the world’s lightest electric conversion system for road and gravel bikes with thru-axle frames. The system was created for cyclists who want the benefits of pedal assist without compromising the character of the bike they already own. Designed for clean integration into performance-oriented setups, it supports climbs, longer distances, and demanding riding conditions while maintaining the feel of the original ride.

The Hong Kong-based startup, led by Founder and CEO Yuyang Nie, is dedicated to advancing lightweight sports technology through the development of next-generation cycling systems. Its founding team brings experience from companies including Samsung Electronics, Xiaomi, Li Auto, Alibaba, and leading e-bike system makers.

At the core of the system is a compact hub motor paired with a bottle-style battery that visually echoes standard bike components. A built-in torque sensor measures pedaling effort in real time and delivers smooth, proportional assistance, while an internal clutch disengages when the motor is not in use to preserve a natural, resistance-free ride.

By combining retrofit capability, real-time torque sensing, and a built-in zero-drag clutch in one system, the company says it has introduced a new approach to electric assistance for performance road and gravel bikes. For riders seeking either simplicity or greater customization, the system comes in two versions.

Cyplore One is a ready-to-ride wheel kit developed for straightforward installation and is compatible with disc brake setups, 700c wheels, and tubeless/clinchers. It can be installed in about 3-5 min.

Cyplore Flex is a modular version, allowing greater flexibility in custom wheel builds, offering rim brake and disc brake compatibility. It typically requires around 25 min in a bike shop, depending on the build.

The system adds electric assistance with minimal added weight. It claims to be the lightest in the market, making it particularly suited to performance-oriented road and gravel bikes. The One’s pre-built carbon motor wheel and battery weigh about 2.5 kg (5.5 lb), the Flex motor and battery come in at about 1.7 kg (3.7 lb).

Both are rated at 250 W and 23 N·m (17 lb·ft), with 25 km/h (EU) and 32 km/h (U.S.) top speeds. Its 36-V, 111-Wh battery gives more than 50 km (31 mi) of range. It can be USB-C charged in 1 h.

The system is built to deliver targeted support for climbs, distance, and demanding riding conditions.

Riders can choose between Smooth, Agile, Auto, and Training modes, each tuned for different riding scenarios, from endurance efforts to climbs, changing terrain, and structured workouts. The system connects to cycling computers via ANT+ and supports ride syncing through the Cyplore app and uploads to the Strava app for access to real-time ride and battery data.

The Cyplore system will be available on Kickstarter. Early backers will have access to a Super Early Bird price before full retail availability. Campaign details and launch updates are available on the official campaign page.
