I agree Tillson, the use of electric transmission just means considerable inefficiency to me. Great on paper though!
The increase in rear hub drives is a good thing, it might stimulate a far better choice of freewheels in both sprocket range and quality. They've been the poor relations of cassettes for far too long.
As SportRider says though, exciting times and the range of consumer choice is ever expanding. If this carries on and the UK market doesn't expand, we'll end up with each of us able to have a unique model!
