Shimano Altus on sDuro HardFour 2.0





The 2018 sDuro HardFour 2.0 features a 9 speed Shimano Altus gear system with simple to use trigger shifters to give the kids full versatility across varied climbs and descents. Remember with crank drive you can use the gears with the assistance.

The smaller 24" wheels on the HardFour offer kids full control and stability. Small enough to manoeuvre around, but big enough to take on a full day's ride and follow the parents through varied terrain.





Tektro Brakes on sDuro HardFour 2.0 Kids eBike


Although kids sized wheels, Haibike have built them with decent disc hubs and Rodi alloy, double wall, rims.

On the 2018 sDuro HardFour 2.0 we see the Tektro hydraulic disc brakes. Simple to use and fairly maintenance free, it's a good option on this 24" kid's bike. With the electric assistance we want to ensure braking power remains solid.

The 24" Schwalbe Table Top tyres are both lightweight & durable in their construction, they allow a faster rolling resistance while maintaining grip at the same time. 

A good choice for a mixture of surfaces.

We are excited about this children's electric bike. A proper German crank drive Yamaha eBike. Finally you can take the kids on a full ride out without the stresses and strains of them getting worn out after a short distance. 


Yamaha Kids eBike System

Yamaha PW eBike System

The new Haibike sDuro HardFour 2.0 is powered by the latest Yamaha electric bike system. This 250w motor offers up to 280% assistance and peaks at 60Nm of restricted torque (on this kids version).

The assistance is set in 3 levels on the kids version - 'Eco', 'Standard' & 'High'. This allows the child to fine tune the amount of assistance required. We also see a new set of controls that loose the LCD screen in replace of simple on / off power and assistance, easy to use buttons.

The Haibike sDuro Hard Four 2.0 2018 kids eBike is offered with the 400Wh Yamaha battery to give a full day's ride time. Now your son / daughter can join you for the longer rides too!

On the Kids version the assistance speed is lowered down to 12.5mph. We want children to have fun whilst maintaining a safe pace. We also remove the walk assist and simplify the levels to make it as user friendly as possible.

You can learn more / read reviews of the Yamaha eBike system on our blog pages.
