Hi everyone,

I'm a newbie here but also to the e-MTB scene so thanks for having me!

I recently got a Bulls E-Core Evo MTB in Europe which I am loving so far. I have seen some apps that offer to unlock the 25kph speed restriction, however, apparently my firmware version (4.9.5) is not compatible. Is there any way to downgrade the firmware from 4.9.5, from what I've ready some guides say yes and others no. Alternatively, are there any online apps or solutions to raise the limit - I'd really like to keep the speedo reading accurate though.

Many thanks for your help!
