Are they planning to design and produce their own drivetrains including the motor and batteries and suspension systems as well?Sticking to bikes if the (UK) pessimists are worried about supply chains the answer is buy British......with no import tariffs. Already one of the best emtbs on the market are Whyte Bikes, or Orange if you are a bike breaker, one of the best for clothing is Endura, some of the best engineered components are from Hope and Burgtec.
( speaking as a Whyte e 180 RS owner and user of a range of Endura clothing I am obviously way ahead of the game)
