Electric touring bike – the key equipment on an e-bike includes an electric motor, a battery and an LCD display with control functions for pedalling assist power. The motors are centrally mounted, in the front or in the rear wheel, and support the cyclist up to a speed of 25 km/h. Aluminium frame, shock absorber, trekking saddle, rack, mudguards, lighting and 28″ wheels are all features of the trekking bike. The traditional transmission system includes external derailleurs, which offer the option of supporting between eight and nine gears.
