This year Haibike have moved their SDURO HardSeven 1.0 machine onto the Yamaha PW-SE drive system from the Bosch motor. A high quality entry-level cross country e-mountain bike, this is just the job if you’re wondering what all the fuss is about riding up hills without breaking a sweat on an e-MTB!

    Haibike SD HardSeven 1.0 2020 Electric Mountain Bike

    New for 2020, the SDURO HardSeven 1.0 uses the Yamaha PW-SE electric motor with its gentler performance curve to help you get up to speed. If you’re new to e-MTB this will show you just how flat those beast hills can be!

    1.0, 1.5, 5.0, 8.0?

    The difference between these machines is more than just price. The HardSeven range is a quality hardtail 27.5” wheel MTB that ranges from the entry-level 1.0 for those who want to get into e-MTB for the first time, while the 8.0 is a high spec machine that will hit your wallet as hard as you hit the trails!

    Yamaha PW-SE motor and 400Wh battery

    The 250W Yamaha PW-SE motor has seen millions of miles of use on e-bikes around the world. It is reliable and solid, offering up to 70Nm of torque to get you up and running at speed. The performance curve allows for a smooth start, and it will get you to the 15.5mph speed limit of the motor nice and quick.

    A 400Wh battery is mounted on the lower frame for good weight distribution, and offers a comfortable range of around 40 miles. If you’re a traditional MTB rider this is a giant leap from your usual distances, taking you farther and harder than you usually ride.

    The control system is simple and should have you focusing on the trail ahead rather than worrying about too many parameters as you ride.

    Tell me more?

    Built around the same geometry as the other three HardSeven eMTBs we stock, the HardSeven 1.0 has a quality Shimano Altus M2000, 9-speed drivetrain that will get you about at speed without relying too much on the motor for support.

    Stopping power is with Tektro M275, 180mm rotor disc brakes, supported up-front with 120mm SR Suntour XCM DS, steel spring forks for those moments you need to jam on the brakes in a hurry.

    Control is with wide, 720mm handlebars and on the track, XLC MountainX tyres.

    New for 2020 is the Yamaha PW-SE motor and 400Wh battery that should give a good 40 miles of riding if you’re conservative on motor power.
