I thought that a legal ebike was looked upon as a bicycle, subjected to exactly the same rules and regulations as an unpowered machine. So, if BHF are banning legal ebikes, aren't they effectively banning all bicycles from their cycling event?
As I understand matters, nowhere in UK legislation is their a provision to ban legal ebikes from public places where ordinary unpowered bikes are allowed to go. I understand that the BHF's ban is probably a condition of entry, but it might not stand up to a legal challenge, especially if the event is run on roads.
We should all turn up on ebikes and join in, accompanying all the entrants. There is nothing that they can do to stop that from happening.
Private sites, such as FC owned trail centres are another matter, but it would seem wrong of them to ban legal bikes for the reasons stated above.
