Emission-free passenger transport is not only a question of environmental protection but also of economic sense. In addition to cleaner air and less noise, an electric bus also ensures flexibility regarding fossil fuels.

The most sustainable way towards electromobility is undoubtedly repowering. Our etrofit kit gives buses with retired diesel engines a second life. We can either supply you with fully converted vehicles or repower your existing diesel vehicles for you.

Repowering – for a better future.
