Browser-based tuning for modern e-bikes and e-scooters

Bosch e-bike tuning

Bosch E-Bike Tuning – Unlock More Speed

Bosch e-bikes are known for reliability, smooth motor support and strong everyday performance. But many riders want more than the factory-set 25 km/h speed limit. That is exactly where our browser-based Bosch tuning solutions come in.

With the EBT Unlock Key, you can unlock many compatible Bosch Gen1 to Gen4 e-bikes on BES1 / BES2 – completely without a chip, without motor disassembly and without software installation. Simply connect your bike via USB data cable, open the browser-based platform and activate your personal licence key.

NEW: Bosch Smart System / BES3 For compatible Bosch Smart System / BES3 e-bikes, we now offer the EBTsmart Unlock Key. This browser-based solution works with many Smart System bikes with or without rim magnet. In Stage 1, assistance can be increased to 32 km/h while keeping speed, distance and mileage values correct.

Whether you ride a classic Bosch system or a modern Smart System bike, MountainTuning offers a hardware-free unlocking solution designed for riders who want more freedom, more comfort and a cleaner alternative to traditional tuning modules.

Ninebot e-scooter tuning

Ninebot Tuning – Wireless Unlocking for Compatible E-Scooters

Many Ninebot e-scooters, including GT3D, ZT3D, G3D, G2D, G30D, G30D2, F3D and F2D models, come with factory speed limits that restrict their full potential.

With the NBT Unlock Key, you can unlock compatible scooters directly in your smartphone browser via Bluetooth – no app, no cable, no installation and no hardware.

Important compatibility note Ninebot compatibility depends on the exact scooter model and product variant. Before buying, always check whether your model is supported by the correct NBT Unlock Key version.

Designed for private use only, NBT provides a modern alternative to classic scooter tuning methods: browser-based, wireless and without opening the scooter.
