Telefunken Kompakt F810 - 374.4 Wh Battery and 20-Inch Wheels

Telefunken Kompakt F810 is a folding electric bicycle with 20-inch wheels, an aluminum folding frame, and a front-mounted motor. Its compact format places the model between a full-size commuter bike and a transport-focused folding e-bike.

Motor And Battery

The F810 uses a 250 W, 36 V front motor with a listed torque figure of 41 Nm. The lithium-ion battery is mounted at the rear luggage carrier and provides 374.4 Wh from 36 V and 10.4 Ah.

The listed assisted top speed is 25 km/h, while the battery range is stated at up to 60 km. Actual range depends on assistance level, rider and cargo weight, terrain, gearing, tire pressure, temperature, and wind.

Folding Bike Equipment

Power reaches the rear wheel through a 7-speed Shimano Tourney drivetrain. The equipment list also includes an LCD display, mechanical Promax V-brakes, a Selle Royal Alpine city saddle, a kickstand, and a luggage carrier.

The bicycle weighs 22.5 kg and uses a 33 cm frame height. Its 20-inch wheel size, 50 mm tires, adjustable stem, and 600 mm handlebar define the fit and handling envelope.

Brand And Market Position

Telefunken's bicycle range is produced under a licensing arrangement rather than by the trademark owner itself. Karcher AG identifies itself as the Telefunken e-mobility license partner and manufacturer, while Telefunken Licenses GmbH holds the license rights.

The F810 is listed for Germany and Austria through Karcher's e-mobility operation, not as a US-market bicycle. A US reader should therefore treat the cited euro-market specifications as a reference for the named model, not as confirmation of US distribution.

Use Case And Limits

The F810 fits riders who need a folding bicycle with electric assistance, a 7-speed drivetrain, and a rear-carrier battery. Its 22.5 kg weight is substantial for carrying up stairs, although the folding frame supports storage in smaller spaces than a conventional city e-bike.

Compared with a non-electric folding bicycle, the F810 adds a 250 W motor and 374.4 Wh battery but also adds battery weight and charging requirements. The model is best understood as a short-trip and transport-oriented pedelec, with range claims tied to controlled riding conditions rather than a fixed travel distance.
