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.

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!

On the 2017 sDuro HardSeven 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 bars, the 2017 HardSeven 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 HardSeven 7.0 offers 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. Want 27.5+ tyres? Check out the sDuro HardSeven 7.0 2017.
