Haibike designed the Life Line especially for women without compromising on power or performance. The hardtails and full-suspension models also offer comfort and safety, providing a perfectly adjusted geometry engineered for women.
Shorter stems, adapted specifications, special saddles and extra small frame sizes characterise the Life Line. In the development of the new models, Haibike further optimised the Ladies geometries.
For improved control and an ergonomic sitting posture the head tube was lengthened; for more comfort and safety Haibike reduced the stand-over height of the top tube.
Crank length, handlebar width and brakes were adjusted as well in order to be able to react even more intuitively and efficiently. The motorisation via drive units of Bosch or Yamaha is as powerful as with the other eMountainbikes of the SDURO family.
The SDURO HardSeven Life models are equipped with suspension forks with a travel of 120mm as standard.
Highlights:
Haibike SkidPlate: Made of shock-resistant plastic, the light component protects effectively from scratches or motor damage.
New Yamaha PW-SE drive unit: The PW-SE engines provide all the popular features of the first PW generation together with improved cadence support up to 110 rpm and Bluetooth connectivity.
Yamaha side-switch LCD display: 1.7“ LCD display for a wide range of use with easy-to-handle screen featuring speed and battery level indication.

* Mountain bikes are sized differently to road bikes. Typically, they are sized in inches as the first MTBs were produced in the USA. European brands like Lapierre and Haibike like to use centimeters for all their bikes. The measurements of their mountain bikes doesn’t match their road bikes but is like a simple conversion from the inches measurement. This is why we have included cm measurements in brackets for the e mountain bike column.
