Mahle x35 derestriction


Finding my (electric) wheels
Nov 10, 2023
Hello. I own a 2019 Ribble fitted with the Mahle x35 system. I have two issues with the bike. 1. I find the available torque isn’t sufficient for hill climbing and 2. I want to add another 5 mph onto the speed available before the motor cuts out.
i’m aware that the X20 system may solve the torque issue but that means I have to invest some 3 to 4 £k into a new bike. Are there any dongles or derestriction devices out there that would add 5mph onto the speed? Yes, I’m aware that this is illegal in the UK. Many thanks.

Hardly a case of 'may' be illegal, at least on UK roads.

Same applies in most of Europe I believe.
