The Yamaha motor of the wife's 2019-model Batavus E-go is well past its best-before so it's time to see about getting it fettled. What sort of a job is it likely to be to remove it? Having spent a large part of my life rebuilding motorbikes it's not the mechanical aspect that concerns me but the electrics. Is it likely to be a simple matter of uncoupling connectors, or am I in for something less straightforward?
