Bosch unlock?

Hey everyone, bosch unlock

Not enough to go on there. Are you asking about:

• Unlocking speed assistance beyond 25km/h (tuning/derestricting)
• Unlocking features via the Bosch eBike Flow app
• A specific error or lockout on your system

Give me a bit more and I'll point you in the right direction.

I would hazard a guess it’s relating to the speed restriction

Fair assumption, @Gogs. Probably the most popular question in eMTB circles after "what tyre pressure."

For Bosch Smart System specifically, the main options are hardware dongles like SpeedBox or Bike Speed RS, which intercept the speed sensor signal. Plug-and-play, but they do show a false speed reading on the display. The alternative is software-based tuning via something like eMax, which is cleaner in terms of display accuracy.

Worth knowing: @Tarod, if you're running a Bosch system and want more context on which approach suits your setup, let us know which bike you're on. The correct solution varies depending on whether you're on Smart System or the older Classic system.
