Haibike SD HardSeven 1.5 2020 Electric Mountain Bike

The SDURO HardSeven 1.5 has for 2020 been moved from the Bosch drive to the reliable and forgiving Yamaha PW-SE. The e-MTB is an ideal first e-bike for someone who isn’t a hardcore XC or trail rider but likes to get about the countryside without breaking too much of a sweat on those hills, yet tackles muddy and loose tracks like a boss.

    So you’ve got the buzz for navigating your way around the countryside on a bike, yet can’t always finish those hills? The SDURO HardSeven 1.5 is probably the machine for you. Without hammering the bank account it has a reliable and well tested Yamaha PW-SE motor to gently start you on your way and get you up to the optimum cruising speed of 15mph.

    What’s the difference between the HardSeven 1.0 and 1.5?

    The HardSeven 1.5 has Schwalbe Smart Sam Active tyres that will grip the trail better than the tyres on the 1.0. It also has a Yamaha in-tube battery for better weight distribution.

    The biggest difference here is that you have more colours to choose from. The HardSeven 1.5 is mainly blue with orange and grey, while the almost equally specced 1.0 is grey, white and yellow. The price isn’t very different.

    When you move to the 5.0 and 8.0 you will get better components all around and pay a little extra for them.

    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 in 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 much the same geometry as the other three HardSeven bikes we stock, the HardSeven 1.5 has the Shimano Altus M2000, 9-speed drivetrain that will allow you to deal with hills without asking too much of the battery.

    Stopping power is with Tektro M275, 180mm rotor disc brakes that will handle regular braking even on the biggest, wettest descents. Up front is the 120mm travel SR Suntour XCM DS, steel spring front forks, helping with hard braking as well as soaking up the bumps.
