Excellent for bicycles. The name "energy return wheel" suggests it offers less rolling friction than conventional tyres.
We should never underestimate inventiveness nor material technological advances, but I still think m/c tyres present extra challenges that will take a while longer to solve.
One downside for manufacturers is they will sell fewer tyres because quite a lot of tyres don't make their full wear life due to punctures or wall/case failure.
Also, if they last longer, we'll all be buying fewer. I'll be like the (urban legends?) that razorblade manufacturers can make blades that virtually never lose their edge, or petrol companies put the brakes on fuel efficient vehicle development.
