Function

With its powerful 3 kW, the Speed-Bull can drive, brake and keep the desired speed constant. Measurements can be carried out or brake pads can be broken in. The road is simulated and everything that is bothersome on the road (cracking noises, etc.) can be eliminated in the workshop. (Because of the human assistance, a range test only works on our large test benches).

Here is a short overview video:

The introduction

If you step on the pedals on an e-bike with constant power (pedal power), a certain amount of power is transferred to the ground on the rear wheel. On the road, the e-bike gets faster or slower, depending on its performance. The Speed-Bull measures this performance. As soon as the support of the e-bike is activated or deactivated, a big difference is immediately visible. That difference is vehicle performance.

However, if a performance diagram or the maximum speed is to be measured, this procedure must take place over a certain speed range. This can be chosen freely.

So that the driver can read his own pedaling power on the display, the Speed-Bull must first determine the power loss due to rolling resistance. This depends on the tire pressure, total weight, tire profile and a number of other factors.

The Speed-Bull can actively drive and carry out all necessary measurements automatically.

Here is a short overview video:

If you pedal on an e-bike with constant power (pedal power), a certain power is transmitted to the ground at the rear wheel. On the road, the e-bike becomes faster or slower, depending on its performance. This performance is only measured on a Speed-Bull.

A big difference is immediately visible as soon as the support of the e-bike is activated or deactivated. This difference is vehicle performance.

However, if a performance diagram or the maximum speed is to be measured, this procedure must take place over a specific speed range. This can be chosen freely.

In order for the driver to be able to read his own pedaling power on the display, the Speed-Bull must first determine the power loss due to rolling resistance. This depends on the tire inflation pressure, total weight, tire profile and a number of other factors. We call this calculation of power losses balancing.

The Speed-Bull can drive actively and carry out all necessary measurements automatically.
What sounds so complicated here is in reality done in a short time.

There are endless possibilities to work with the Speed-Bull.


The exact process is explained in the tutorial 3 Ramps.
