Misplaced concerns over Quantyaparx, an off-road electric dirt bike park in rural England
Quantya UK has a plan to build QuantyaparX - which would be dirt bike tracks featuring only electric dirt bikes. Of course it would be one brand, Quantya, rather than offering multiple brands (Zero, etc). Still it's an interesting idea.
Unfortunately they ran into opposition from locals who didn't understand that electric=quiet. They must have heard "dirt bike track" and with memories of a motocross race last year spewing noise pollution for miles around, they rose up en masse and shouted NO. Sorta.
