The Sduro Nine / Seven eBikes are the optimal choice for those looking for an eMTB for easy terrain or tours. The wide variety of bikes and the attractive price-performance ratio make this series one of the most successful worldwide.
Yamaha PW Drive Unit
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.
Yamaha Multifunction LCD display
The Yamaha multifunction display provides a quick overview of all the Yamaha system features. The removable display can be mounted in different positions and is operated by the remote on the handlebar. Information available includes: the selection and display of the support levels (Off, Eco +, Eco, Standard, High), battery charging level, remaining range, current, average and maximum speed, daily and total distance traveled, time, and the current support level. Via the remote the light on the eBike can be switched on and off, and walk-assist can be activated.
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 from below. Similar to a helmet, the SkidPlate protects the motor from damage and is strong enough to absorb even the hardest of strikes that would otherwise damage the motor. HAIBIKE uses a special, impact-resistant plastic that is able to perfectly distribute force and withstand deformation of its shape. Unlike metal, which would bend permanently, plastic springs back to its original state. The paint color conceals scratches and damages, and if necessary the SkidPlate can be replaced easily and inexpensively.
Gravity Casting Interface
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. HAIBIKE started using a casting process from the motorcycle industry, gravity casting, in 2010. Negative molds are created from compressed sand, filled with aluminum-zinc alloy, and then rotated along precisely calculated axes. Thanks to gravity, there is uniform thickness throughout the casting. The raw cast aluminum parts are controlled by X-ray analysis and then reworked in a computerized process that ensures a consistently high level of precision, and a finished interface that is low weight and high-strength.
Integrated Motor Concept
The motor is the technological core and defining characteristic of an eBike. Thanks to the Gravity Casting motor interfaces HAIBIKE 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 SkidPlate is a useful protective device from a technical perspective, but also allows HAIBIKE to optically integrate the motor to make it part of the frame. Unlike other integration concepts, the motor looks like a natural part of the eBike.
