The Skarper ebike conversion kit offers an innovative way to transform almost any bicycle with disc brakes into an electric bike. Unlike traditional ebike conversion kits, the Skarper doesn’t require major modifications like changing the wheels or installing a hub motor. Instead, it uses a clip-on system that attaches to the bike’s rear disc brake. This compact unit, weighing about 4 kg (8.8 lbs), houses the motor, battery, and electronics, providing a simple and non-invasive solution for cyclists.
The heart of the system is the Skarper’s custom disc rotor, called the DiskDrive. To install it, riders replace their bike’s standard rear disc brake rotor with this special rotor. Once attached, the motor inside the Skarper unit engages the rotor, driving the rear wheel through internal gearing. This setup allows for assisted cycling without changing the bike’s core components, and the motor can be quickly removed when not needed, turning the bike back into a regular pedal-powered machine.
With a 250-watt motor and 45 Nm of torque, the Skarper provides a helpful boost, particularly on hills or during long commutes. The kit offers a top assisted speed of 15.5 mph (25 km/h) to comply with European ebike regulations. There’s no throttle, so riders need to pedal to activate the motor’s assistance. This system is ideal for those who want a more natural cycling experience with the added benefit of electric power.
The Skarper’s battery offers a range of 18 to 31 miles (30-50 km), depending on the selected power mode. Charging the battery takes about 2.5 hours, but a quick 30-minute charge can provide up to 9 miles (15 km) of range, making it a practical option for daily commuting. When riders reach their destination, the entire unit can be unclipped and stowed in a bag, further adding to its convenience.
One of the Skarper’s key selling points is its simplicity. Unlike other ebike conversion kits that can add significant weight and drag to a bike, the Skarper leaves the bike nearly unchanged when the unit is detached. This makes it an appealing option for cyclists who want the flexibility of an ebike without the permanent changes or added bulk of a traditional electric bike.
However, the Skarper’s price tag may be a concern for some buyers. At £1,395 (about $1,650), the kit is more expensive than many entry-level electric bikes. While the cost includes the convenience of being able to clip the motor on and off, it still represents a significant investment, especially for casual cyclists. Pre-orders are open now (though currently sold out), with the first units expected to ship sometime in 2024.
