The Speed-Bull is a small, lightweight roller dynamometer for bicycles and e-bikes.
The possibilities are so diverse that they are described on a separate website www.Speed-Bull.de.
This test bench is also one of the static test benches, because it is the driver who has to pedal and not a machine, not nearly as precisely. For workshops or importers, however, this is completely sufficient.
This test bench can be used very universally for this purpose. Even new brake pads can be braked with it.
