The Pinion MGU motor presented at Eurobike 2023 has greatly impressed us. The concept of a low-wear automatic gearshift combined with a powerful motor sounded promising.
Therefore, we made efforts to obtain a Pedelec equipped with it promptly. And our expectations were not disappointed. Our touring bike with the new Pinion MGU E1.12 is a lot of fun to ride and at the same time very comfortable. The configuration options for the gearbox leave nothing to be desired, and we find the integration into the FIT system very successful. The operating comfort achieved thereby is unparalleled. The gears are changed very quickly and effortlessly compared to a conventional chain or hub gear, even under load or at a standstill, and the noise comfort provided by the low-wear belt drive also brings a pleasant riding experience.
In this scenario, of course, the 25 km/h limit is a limitation. Therefore, we have examined the possibility of tuning for this combination and are already riding a prototype that significantly increases the fun of riding.
This is actually one of the most frequently asked questions we receive when it comes to tuning Pedelecs with the Pinion MGU motor. With the motor software version V 1.1.3, which was installed in the first bikes that were delivered, this was indeed not necessary. However, since the motor software update to V 1.2.0, this has changed.
With the previously known Pedelecs with mid-drive motors on the market, the speed at which you rode didn’t matter to the motor. A higher speed could simply be achieved by using a higher gear. Since the gear shifting was outside the motor, this could easily be done. For the motor, this was like riding up a small hill.
This changes with the Pinion MGU motors. Because the gearbox is integrated into the motor and electronically monitored, these motors can only be tricked into reaching a higher speed if a different transmission outside the motor is installed on the bike. For this reason, modifying the pulleys is absolutely necessary.
You can calculate the necessary values for the new achievable top speed with motor assistance using our online tool: Pinion MGU bikespeed Calculation-Tool
We usually receive this question immediately after explaining the reason for modifying the pulleys. The electronics of the Pinion MGU motors not only monitor the integrated gearbox but also check whether the rear wheel speed reported by the speed sensor matches the expected value. Additionally, the bikespeed-RS ensures that all values are displayed correctly on your FIT display or app.
The bikespeed-RS tuning requires the value of the gear ratio of the pulleys in their original state when the bike was delivered. You can also calculate this value using our Pinion MGU bikespeed Calculation-Tool.
The calculated value must be entered into your bikespeed-RS tuning. The procedure for doing this is explained in the included Manual.
