Haibike SD Hardfour 1.0 2020 Electric Mountain Bike

Could your fast growing offspring need a little more freedom without always resorting to the ‘Dad Taxi’? Do you as a family like to go riding but want to do bigger distances, possibly over tougher terrain than the standard fare of railway/canal paths? Have they just done well at exams and need high praise in the form of a machine like the SDURO HardFour 1.0? These and many other reasons may lead you to invest in a decent machine that will last at least until their legs grow too long for it!

    Haibike SD Hardfour 1.0 2020 Electric Mountain Bike

    If you want to take your child on a longer ride - even 20 or so miles - and not find yourself slowing down to manage their stamina, then the SDURO HardFour 1.0 could be the very machine for them. A smaller frame for shorter legs is complemented with excellent components, enabling your little one to keep going - possibly long after you yourself need to stop!

    Yamaha PW-TE motor

    The Yamaha PW-TE motor is new for 2020 and is designed with gentle acceleration and ease of use in mind. Its four cadence sensors in the crank shaft enable the controller to make fast adjustments according to what it perceives is going on, be it a hill, start or descent.

    The controller also has an ‘auto’ setting where the computer decides how much power to offer the rider according to the terrain and conditions, giving the rider a lot less to think about as they go about their business/fun!

    Tell me more?

    In a lairy yellow colour scheme, this 34cm frame hardtail SDURO HardFour eMTB is a bike that no one will miss in a crowd. A 9-speed Shimano Altus M2000 drivetrain runs over an 11-36 tooth rear sprocket to give a great set of ratios that will help them blast over most of those inclines without even a teenage whimper. 

    Stopping power is with Tektro M282 disc brakes on 160mm rotors - a serious bit of kit for a little bike. The Schwalbe Table Top Performance tyres will help them on road and off, and should last quite a few power slides should that be the sort of thing that floats their boat!

    For a typical adult a 400 Watt hour battery can get you a good 40-50 miles. With a lot less lard on the saddle, a kid can get as much as 70 miles per ride. As such on a machine like this, the battery could wear you down too!
