Dutch company Drymer developed a 'three wheels' with electric support with TechnologieCentrum Noord-Nederland, of Groningen, and the support of many national and European institutions.
The two front wheels of the Drymer ensure a stable driving experience and lean in the windings to be able to take them quickly. Cycling is supported by an electric motor of 250 Watts which offers an assistance up to 25 km/h. It is not possible to do better unless transforming the Drymer into a motor bike and therefore obliging to wear a helmet. Drymer exists in open or covered version. The only problem is the cost: 6.000 euros. Perhaps because it still at an experimental stage.
