I took delivery of Kett Allaround April 2012. I have ridden it 6 times for no more than 35 miles. The fabric on the seat is fraying along the vertical support on the left side of the trike. Not what I expected from a machine this expensive. Is the seat replacement covered under warranty? The trike has been babied, stored inside, and never been ridden anywhere except on level paved trails in local parks.
