At Eurobike 2025 today, Kamingo is launching a revolutionary lightweight e-bike converter that transforms any standard bicycle into a high-performance 750-W e-bike in just 3 min on first setup and a mere 10 s for subsequent daily rides using a “tool-free” kit with one “screwer.”

“We created Kamingo because we believe people shouldn’t have to choose between the joy of their favorite bike and the convenience of electric power,” said Julian Lee, CEO of Kamingo. “This isn’t just an upgrade—it’s a way to make cycling more accessible, flexible, and fun for anyone, whether it’s a daily commute or a weekend ride.”

Lee previously worked at Huawei, and the structural engineer brings experience from BYD. He leads a team with deep expertise in mobility and consumer technology.

Designed for a broad audience of commuters, weekend riders, and cycling enthusiasts, the e-bike converter includes three modular components: a handlebar-mounted controller, a battery that fits into a standard bottle cage, and a rear hub motor that mounts via a quick-lock base.

The controller raises or lowers the assist motor, adjusts assist levels, and supports both wired and 2.4-GHz Bluetooth connections. It displays speed, range, and controller battery level, with an auto-alignment warning system for added safety.

Mounted on the seat stay with a quick-lock base, the 0.9-kg (2.0-lb) motor delivers power of 250 W (rated) and 750 W (peak) for quiet and efficient response on demand. The advanced PMSM (permanent magnet synchronous motor) features an FOC (field-oriented control) algorithm and a torque-boosting gear-reduction system, delivering up to 40 N·m (30 lb·ft) for what’s said to be smooth, powerful acceleration just like a full e-bike. Assisted speeds can reach up to 25 km/h (15 mph) in most EU regions, and up to 32 km/h (20 mph) where local regulations allow like in the U.S.

Installed in the bottle cage mount, the battery connects to the motor via wire and features magnetic fast charging at about 3 h. The 1.4-kg (3.0-lb) pack, made up of 16 automotive-grade high-density 21700 battery cells (266 W·h), is easily removable for off-bike charging. Depending on riding conditions, assist mode, and terrain, the system delivers a range of up to 30-90 km (19-60 mi) per charge.

Riders can switch among three dynamic modes without stopping the ride. Assist mode is for pressure-sensitive electric support that adapts to pedaling effort. Cruise mode supports throttle-powered riding without pedaling (in supported regions). Standby mode is for traditional cycling with zero resistance for natural bike pedaling.

The company’s pressure-adaptive technology (PAT) and its innovative motor lift system enable real-time switching between ride modes without compromising safety or ride experience. It automatically adjusts contact pressure between the assist wheel and tire, ensuring smooth, consistent performance across varied terrain types and rider input. The motor adjusts slowly and intelligently, ensuring smooth transitions, and it prevents slipping and detects obstacles like stone jams. Regenerative braking captures energy during braking/downhill to recharge the battery.

The system operates at about 56 dB for near-silent riding. It features an IP66-rated waterproof and dustproof system, plus a drainage tire design for added stability on wet roads. An onboard IMU cuts motor power instantly if the bike tips over 45°.

A Bluetooth-enabled lock secures the motor remotely via the iOS/Android-compatible app to prevent theft. An integrated mini mudguard system is included, with an optional fender available. A built-in power bank via USB-C keeps phones and devices charged.

The kit works best with standard or semi-slick tires for the broad range of city, MTB, trekking, folding, and select gravel bikes. It is suitable for urban streets, paved paths, and light gravel roads, but it is not recommended for bikes with deep-tread mountain tires.

Kamingo is available via Kickstarter. Early backers can reserve the device at a special Super Early Bird price of $349 vs. the normal $589.
