Hello, just joined the forum so only just navigating about. Quick query, having purchased an ebike Carrera Crossfire, its taken me a year to stump up the will to commute (Plymouth area which is very hilly for Southern softies) I now need to invest in a rear (or front) rack to hold by commuting back pack. I notice that the rear mount are much wider apart on the bike, so a standard (affordable) rack doesnt fit. Any suggestions on economical options? Thank you in advance for reading and even more gratitude for any replies.
