  • Rolling on 20" wheels while still fitting full sized riders means the Radius Tour fits the bill for those needing a compact but powerful bike.



When space is at a premium the Radius Tour delivers in spades with its compact design,  telescoping stem and folding pedals. Utilizing a Yamaha PW-System drive system means you'll have plenty of assist to tackle the city streets.


    Made of shock-resistant plastic, the light component protects effectively from scratches or motor damage.
    The Haibike SkidPlate

    Especially eMTBs often suffer from impacts or stone chipping which damage the low-situated motor severely. Therefore, we were the first manufacturer to introduce the SkidPlate back in 2013, a protection element which protects the bottom side of the motor.

    Bottom side protection

    Here the concept of a 'sacrifice part' applies: Similar to a helmet, the SkidPlate absorbs impact forces by deformation or destruction which would otherwise damage the significantly more expensive motor.

    Powerful, reliable and proven: The PW engine from eBike drive pioneer Yamaha provides dynamic support up to 20mph and allows a dual chainring.
    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 70Nm, its compact size, and its low noise, the Yamaha PW is one of the best eBike systems for sporty use.
    The original Yamaha display offers a range of features and information. It is conveniently controlled via a remote on the left of the handlebars.
    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.
    The first lighting which was especially developed for sportive eBikes. Optically, it suits the bike very well. Luminous and retrofittable on all XDUROs and SDUROs with Bosch drive unit.
    The Haibike eLight System

    Lighting on a bike is an important safety feature and allows you to ride your bike beyond daylight hours. However, standard lights stand in contrast with the character of sportive bikes. Plug-on lights also remain foreign items, both technically and optically, on the bike which is why we developed the eLight system which combines functionality and optical integration.

    Bright but invisible

    The front and rear light are designed to be positioned extremely close to the frame so they visually become part of it. The rear light is visually almost completely integrated due to its rod shape.

    Retrofit any bike with Bosch system

    Headlight and rear light are conform with STVZ. You can retrofit both indivudually or as set on any XDURO and SDURO with Bosch drive unit. Switching on and off takes place via a light button on the Bosch display. The result is a naturally appearing light system which integrates perfectly in sportive bikes.
