Hi Understand about the tension requirement, however tensioners are available already for chain drive and so the principle should work for belts.
also the birdy has suspension and is therefore a ltttle different as iirc on the brompton from the geometry the pressure when one is riding should hold the tension into the belt ?
Just thought it would add to the weight clenliness and agility of the package....
