Hi I'm being using the Brompton Pro since the beginning in 2020. Everything went well have good support but recently I request for a new pedal sensor for the Brompton back in May 2023 and already paid the product replacement but nothing arrived and even contacting customer service and been promised many times. Yet its nothing. I know the launch the new pack now and for us that been using the old big battery still dont get enough support. Really disappointed. The thing is I love the product and the best conversion for a brompton but please dont ignore your loyal customer thaat are with you since the beginning.
