I have a Universal kit on my Orange E4 (which is probably sacrilege but at 84 who cares) and I love it. It flies! I can do all the recreational routes again that I used to do when I was 65. I highly recommend it. Bit of irritation over delivery. I ordered it in September 22 and was told it would arrive in March 23. It eventually arrived in mid June. A couple of thing to comment on. I found one other point that mentioned in the manual, regarding the magnetic ring alignment and its sensor. It's advised where there is limited fitting space, the bracket and lugs should be removed from the sensor before securing with plastic ties. I found, on the painted surface of the bike's frame this method did not secure the sensor tight enough. I had to re-enforce with plastic tape. The Mount comes with 3 extra leads that are intended for accessories. In my experience electronics and British wet weather don't go well together. Perhaps some protective caps could be added to the kit Finally, I'd like to buy an OLED display or a second battery but it appears I have buy a full kit to achieve this. So far no reply to my query with Customer Service Apart from these minor niggles, the kit is brilliant. Highly recommended
