With a smaller frame height of 34cm, a lightweight 6061 aluminium alloy frame and a high-performance Yamaha PW motor, the Haibike SDURO HardFour 2.0 2018 is perfect for shorter riders looking to hit the trails.
Although kids sized wheels, Haibike has built them with decent disc hubs and Rodi alloy, double wall, rims.
Powered by the Yamaha PW system, the HardFour 2.0 runs a 250W motor providing up to 280% assistance, but limited at 60Nm of torque and to 12.5mph. With a 400Wh battery as standard, family rides across all surfaces won't be cut short because of a lack of charge.
Three modes of assistance are available on the HardFour 2.0; Eco, Standard and High. To maximise concentration on the trails, Yamaha have fitted the bike with a simple LED display, providing information such as assistance mode, battery life and speed.
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.
