With 100mm of travel, this hard tail electric bike for 2017 is the entry level model within the Haibike sDuro range.

As a keen e-bike rider I have been waiting a long time for a ladies mountain e-bike. I feel this bike was built for me, the handle bars are in the perfect position, the seat is reasonably comfortable. Wow FINALLY a ladies e-bike that looks and feels awesome.

New Features

The new Haibike sDuro HardLife 4.0 ladies eBike is based on the popular HardSeven but with women's specific electric bike geometry and styling for 2017. 

Offered with a Shimano Altus 9 speed gear system, with fast acting trigger shifter's and front chain guide. 

Featuring the Yamaha eBike system and 400Wh battery, this bike is great for getting out and exploring the great outdoors.

The 100mm travel Suntour front forks are both lightweight and comfortable. With air adjustment depending on the riders weight and a full lockout function it can be fast and nimble where require or opened up for superior comfort. 

Shimano Altus on Haibike sDuro HardLife 4.0 2017

The 27.5" wheels are made up of XLC disc hubs which are quick release front and rear, these are laced onto Rodi disc specific alloy double wall rims and Sapim double butted spokes. A strong but lightweight wheel set, perfect for your everyday biker in 2017!

Tektro Brakes on sDuro HardLife 4.0 2017

On the 2017 sDuro HardLife Ladies 4.0 we see the Tektro hydraulic disc brakes front and rear with larger 180mm rotors for increased stopping power. 

Although the entry level model sDuro, Haibike have also managed to squeeze a decent set of Schwalbe Smart Sam tyres into the equation. 

These tyres offer decent off road grip but don't pick up too much resistance on tarmac or hard pack terrain. 

Finished with lightweight alloy stem and wide 720mm flat bars, the 2017 HardLife 4.0 comes in at just 21kg! 

Couple this with a Selle Royal Voga saddle and XLC sport lock-on grips it's comfortable too. 

The Haibike sDuro HardLife 7.0 offers Ladies a great way into electric mountain biking without breaking the bank, a popular model, we expect it to be popular again for 2017. It bridges the gap between the cheaper hub powered bikes and offers a good quality bike with the same tech as some it's bigger brothers at a fraction of the cost. Now in an all new women's specific format.
