    Haibike SD HardNine 5.0 2020 Electric Mountain Bike

    Fast yet comfortable, this SD HardNine 5.0 is definitely a machine for those who like to do miles and miles away from the road. 29ers make for great XC machines as they aren’t too bothered by the little lumps and bumps - with its 500Wh battery you can chew up many a mile indeed!

    HardNine vs HardSeven

    The SDURO HardNine series is for those who like to travel distances and won’t hit too many sharp turns/dodge too many tree limbs as you go along. As far as e-bikes go, the HardNine definitely prefers the hills to the trails!

    The HardSeven with its all-rounder 27.5 inch wheels, while built for XC will handle the sharper turns of forest tracks a little better.

    Yamaha PW-ST - new for 2020

    100 grammes lighter than its 2019 brother, the Yamaha PW-ST is a country mile better. With four cadence sensors in the case, it can deliver power at speeds of more than 100RPM, a limitation of its predecessors.

    In addition there is the new ‘auto-mode’ that allows you to leave the bike to decide as to the power setting it needs for different terrains. The unit can also detect how much power to deliver when starting so you don’t have wheel spin or pull a wheelie when you pull away.

    This is all controlled with the Yamaha SideSwitch controller that is discreet and doesn’t show you so many parameters that you’re distracted from the job at hand - having a blast on the hills!

    Tell me more detail!

    The 10-speed Shimano Deore M6000 drivetrain passes over an 11-42t set of ratios and allows you to be economical on the battery should you choose. Stopping power is amply delivered with the Shimano MT200 disc brakes on 180mm front and 160mm rear rotors, allowing for decent speed control in most conditions.

    A 100mm travel, SR Suntour XCM34 LOR steel spring fork will smooth out the bumps, and grabbing the track or road well are Schwalbe Smart Sam Active tyres that will forgive you on road but grip well on the loose/wet stuff.
