SDuro Hardseven Life 2.5 400Wh Women's Electric Hybrid Bike (2019)


Regular price £1,949.00


The Haibike SDuro HardSeven Life 2.5 Street 27.5” Women's Electric Bike is designed specifically for women. It is ideal for cycling on mixed terrain and is suitable for roads, paths and mild off-road use.

It features a 400Wh Yamaha PW-SE motor, Yamaha Side Switch Display and control switch, 10-speed gearing and Suntour's XCM 100 mm travel Suspension fork to smooth out rougher riding surfaces.

Tektro hydraulic disc brakes front and rear with larger 180mm rotors will ensure you have more than enough stopping power while the Rodi Black Rock alloy double wall 27.5" rims wrapped in Schwalbe tyres are both lightweight & strong.

The Yamaha PW system uses a 400Wh battery and a 250Wh drive unit, which delivers up to 70 Nm of torque to assist you whatever the terrain. It also features Bluetooth connectivity and the Yamaha Sideswitch display gives all the information you need including speed and battery level indication. The different assistance modes are also controlled by this unit.

This particular model also features two full-sized mudguards, a kickstand and built-in front and rear lights which are powered by the built-in main battery ensuring you are able to ride in a range of weathers and both day and night.
