Don't understand this love of chains vs a belt. A belt is much more tolerant of all the road dirt that collects around the back of our cars .... chains wear out ... with the steel rather than aluminium spocket, we have a reliable low maintenance solution. The only possible benefit is that one can take the chain out to change it without dismantling the rear end ... but chains need changing more often anyway! Besides the belt on our M3W, we love the belts on our eBikes that are far less hassle than a chain with no obvious wear after 10,000+km.
