Delivery of my Swytch kit was within the window - though only just, by one day! The A frame mount I'd ordered wasn't available, so I was offered a seat post mount instead, which works well, though the cable runs are long. (the A frame mount has very recently now arrived, but I'm thinking twice about fitting it as all the previous work will need to be redone). So far no problems with the kit, which seems pretty robust and was generally easy to fit. Customer service was great though, quick responses, extra cables provided free of charge - very good indeed. The riding experience is good - smooth power delivery and good response to the brake sensors etc. Changing power levels on the standard handlebar mounted LED display can be a bit tricky on the move though. The lowest power setting is enough to overcome the drag of the motor and provide gentle assistance, giveing just over an hour's riding, depending on the terrain. On higher settings the battery drain is noticeably greater. So for local rides it's perfect, but I've bought another conventional bike for longer trips!
