Try a new motor and run Turbo Studio if you leave it installed
Connect all the components without fitting the new motor in the frame. Test with ‘walk assist’ from the handlebar remote. A newmotor should only be fully fitted if the issue is solved with a new unit. This will save a lot of time should a replacement motor not be the solution.
Note: Whilst testing another motor Turbo Studio will prompt a Component Change. After completion, carry out any recommended updates to all components to fully check the system.
