The Speed-Bull is developed and manufactured in Bavaria, near Neuschwanstein Castle.

Short distances and regional suppliers are just as important as high quality.

We attach great importance to sustainability and reject planned obsolescence.

We don’t know what challenges will be faced in the future for e-bikes or the Speed-Bull.

That is why this system has a modular structure. The components can easily be replaced or modernized.

The connection cable to the PC is very often damaged.

The Speed-Bull is of high industrial quality and designed for a long life.

We can prolong this life indefinitely.
