45 km/h on an e-bike frame

With the M25GTS motor generation, Tranz X designed a drivetrain solution for modern s-pedelecs. It can be integrated into e-bike frames.

The motor generates a maximum torque of 70 Nm with its 400 W. This output gives a maximum speed of 45 km/h before the electronic speed limit unit is automatically engaged. The drivetrain solution has a noise emission of about 70 dB, even with the higher power output. The motor can be integrated into the frame design of modern s-pedelecs with center motors.

The city e-bike Radar Speed, manufactured by Winora, is an example for the impact of a smaller motor on the overall e-bike design: the motor is nearly invisible and with 4,08 kg weight the M25GTS turns the Radar Speed into one of the lighter e-bikes in its category.

The center motor comes with Tranz X’s Logi X-technology. Tranz X first introduced its digital communications system Logi X in 2014 and has constantly developed it ever since. Based on the CAN technology, the manufacturers’ own product communication system offers a diagnostic software that checks the motor performance. The company will show its products at the Eurobike fair in Friedrichshafen, Germany from August 31 to September 4, 2016 (hall A6 booth 406).

Diagnostic software for e-bikes

With the diagnostic software Logi X for e-bikes, bicycle dealers are able to diagnose the exact error of the individual components on their own PCs. Connected through a single USB cable, the software can perform self-tests to read all relevant data and specifications of the e-bike.

The software is currently available in four languages: German, English, Dutch, and French. Dealers can download and install the necessary software from the company’s website straight to their own PC. Registration in the dealer area of the website is required.
