Important Legal Reminder

Like any e-bike tuning solution, using the EBT Unlock Key disables the legal classification of your e-bike as a Pedelec. In most countries, this means you may no longer use the bike on public roads unless it is registered, insured, and fulfills all legal requirements.

Looking Ahead

At MountainTuning, we are constantly pushing the limits of what’s technically possible. Our team is already researching future unlock solutions for the latest Bosch Smart System (BES3) – aiming for software-based tuning without any chip or physical device.

We're also keeping a close eye on systems from Yamaha and Shimano – evaluating whether similar web-based solutions could be feasible in the near future.

It's too early to promise anything, but one thing is clear: The future of e-bike tuning is digital – and MountainTuning is leading the way.
