The bike has already been returned to Raleigh (after 4 failed repairs by the dealer) and was returned on Saturday - a week without the bike - but after just over 2 miles on Sunday (first day of trying it after return from Raleigh) 4th and 5th gears started slipping again on a very moderate incline that even I can take in top gear with ease on a non-electric bike. I've had it with this Raleigh bike, so I've been in touch with the dealer to ask for a replacement bike or refund so I can purchase a different Ebike. Not had a response from him as yet. But I do have it in writing from a Raleigh Manager, in more than one email, that they expect chain replacement every approximately 300 miles. That's perhaps a good reason for not buying Raleigh in future. I have to say that the tone of Raleigh in their Emails is not what I would expect towards a customer who paid £2000 for an ebike and who has had nothing but trouble since purchase........................................
