The Gruber Assist Motor Drive
On display at ExpoBici in Padova was a Kuota road frame equipped with a Gruber Assist motor. The interviewee is Production Manager Dido Kopp.
The battery for the motor is under the saddle and you can see someone starting the motor by pushing a red button underneath the saddle.
The current implementation of the Gruber Assist motor requires a straight seat tube in aluminum or steel (carbon not possible) of 30.6 or 31.6 mm. Development of a motor for carbon bikes is underway. Bikes can be retrofitted by a Gruber certified dealer.
The interviewer asks Kopp "If you are doing 30 km/h what kind of an improvement will you see?" The response: "10 km/h increase." You can find all the technical specifications at Gruber Assist, www.gruberassist.com
