I know I may have to defend it, but I'm thinking Mahindra's plan may be a great idea. In fact, I don't see why they need to make internal combustion bikes at all. There are plenty. Would any of us really enjoy a modern internal combustion machine just because it has the name "BSA," but bears no real heritage with BSA nor has the caché? May as well get a new Ducati or Triumph. If they do it right, and in the Midlands, this could be a new BSA that is unique and has meaning. As for RD's argument, I suppose he/you has/have a giant stash of dinosaurs and primordial vegetation in the final stages of transformation just before becoming oil. As for electric bikes in general, if you get a chance, try to take a look at "Long Way Up" with Ewan McGregor and his friend riding HD Livewires from Tierra del Fuego to Los Angeles. Here, it's on Disney+.
