The SDURO HardFour 4.0 was designed to inspire a new generation of riders and is the first e-bike designed specifically for kids. Built around 24-inch wheels, it features all the technology and innovation of Haibike’s award-winning SDURO HardSeven. The 500W Yamaha mid-drive motor is powered by a 400 Wh battery that can be charged directly on the frame or off. This electric performance bike also features hydraulic disc brakes, a Shimano 9-speed gear system, and Schwalbe Table Top tires. To ensure a safe yet thrilling ride, the Yamaha motor is governed to a top speed of 12 mph.

Conventional eBike motors sit low in the frame and run the risk of being damaged by strikes to the underside of your bike. in 2012 Haibike introduced the SkidPlate, a simple protective element that effectively protects the motor.

The centerpiece of the frame: the motor interface. At this connection point many important functions come together: the engine mount, swing arm, and shock mounts, and the battery and downtube connection. The more stable the interface is, the more stable the entire frame is.

The motor is the technological core and defining characteristic of an eBike. Thanks to Haibike's Gravity Casting motor interfaces, they can integrate the motor in a compact manner without separate mounting plates. This concept reduces the space required to mount the motor and decreases the visual volume of the engine.

The Yamaha PW unit is proven to be a powerful and reliable motor. Thanks to its Zero-Cadence system, it supports the rider from the first revolution of the crank. As one of the few motors available allowing a dual chainring, the Yamaha system is able to offer a broad range of gears providing more gear options out on the trails. Given its high maximum torque of up to 80Nm, its compact size, and its low noise, the Yamaha PW is one of the best eBike systems for sporty use.

The Yamaha LED display is a compact yet robust display and remote unit. Despite its small size, it provides the rider with all essential information. Positioned on the left of the handlebars, the remote is easily accessible. Information available includes: the selection and display of the support levels (Off, Eco+, Eco, Standard, High), the current speed, the battery charge level, and the remaining range. The display also allows you to switch on and off of the main light.
