Motor Bosch Active Line Plus
An available variant of a branded central electric motor with a smoother and less aggressive characteristic will help. With a nominal power of 250 W and a maximum torque of up to 50 Nm, you will always have enough power in stock to overcome all terrain, road and city obstacles without distinction. The design of the engine without internal gears allows the use of cranks with a classic size converter.
Battery BOSCH Power Pack 400 Wh
Bosch Power Pack 400 Wh - high-capacity battery that brings new energy to e-bikes. Thanks to its placement on the frame, it does not affect the center of gravity, and the electric bike has ideal balance. The battery is equipped with a BMS board (Battery Management System), which protects the battery from overheating, short circuits, or overcharging.
- the batteries do not have a memory effect—they can be charged even after a short ride or while riding.
- battery life is 600 - 1000 full charging cycles
- battery life in km is around 15.000 – 25.000 or 5–9 years
- charging time to 80% capacity is approximately 2 hours (4A charger)
- the battery weighs approximately 2.5 kg
Display BOSCH Intuvia
The Intuvia display can be read under all lighting conditions and the eBike can be controlled easily and intuitively. Thanks to the separate control unit, your hands remain securely on the handlebar at all times, while the shift recommendation means you always pedal in the correct gear. This preserves the battery and increases your range. Intuvia means you always have all riding data clearly in sight.
