    With a 20 speed, single rear cog drivetrain, the Haibike SDURO HardSeven 4.0 is a machine that flattens hills - even if you aren’t asking too much from the powerful battery. A great mid-range eMTB, it is as happy off-road as it is on. Let’s face it, in the UK on a typical XC ride you’re as often on hard surfaces as you are on tracks and fields even on a longer ride…

    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-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 you’re distracted from the job at hand - having a blast on the hills!
