SDURO opens up the world of sporty innovative ePerformance bikes to a wider range of riders than ever before. Comfort, quality and class leading performance has never been so accessible.

New for 2019 across all Yamaha equipped models is the introduction of Yamaha PW-SE motors – with improved response to higher cadence and a higher torque output.

Across HardSeven, FullSeven and even Cross & Trekking models we’ve introduced intube batteries, not only for a sleeker look, but so that Yamaha models can benefit from our Modular Rail System line of accessories. Our Bosch equipped Trekking and Cross models have been improved too making them more accessible with rider focussed Bosch Active plus systems.

The HardSeven comes with agile 27.5" wheels available in wide or comfortable plus tyres, for tours in easy terrain. You also have the choice between high-quality, light aluminium frames and different drives.


Haibike Intube battery concept (IBC): The new InTube battery enables a high integration, a beautiful shape and functionality. It is available in many of our models.

Haibike Modular Rail System (MRS): The ModularRailSystem allows simple and fast mounting of different equipment on the bike.

New Yamaha PW-SE drive unit: The PW-SE engines provide all the popular features of the first PW generation together with improved cadence support up to 110 rpm and Bluetooth connectivity.

I find this bike fantastic round the Derbyshire peak district . Run with the power off when not needed and full power to flatten out the hills gives you a massive battery range.and love the colours
