other than market #enshitification or bias toward absence of real hills and cargo, why are there no #eBikes with both crank+hub drive motors combined?
Hub motors give smooth power and regen braking but can't gear down for steep slopes. Getting started with the crank drive gets the hub up to an effective speed without putting so much force through the chain (and human-scaled cassette) while the hub bridges the shifting gaps. Regen braking greatly reduces brake pad maintenance & extends range.
@jef that was my original plan for the bakfiets, but I like keeping the rear light so I can lift it and wheelbarrow around obstacles. The longtail has a similar ability to lift the front wheel and pivot. Spreading the traction to both wheels might be worth the added front weight for some applications but I think you need a fairly large geared hub motor to get good regen braking.
