Hello everyone! I have a Bergamont e revox edition eq. It is a very good bike and I use it to go everywhere. The 25km/h speed limit, however, is a bit slow and I want to be able to speed it up just a tad. I've read that Bosch makes US firmware that caps the bike to 32kmh.

Is there a way to change my bike's firmware without taking it to a shop? I don't want to unlock it via speedbox or any other mod that might piss off the software and make it go limp, furthermore I really want the motor to last as long as possible and I don't think these mods positively impact the motor's lifespan.

Thank you!!!
