The delivery: obviously it was slightly longer than hoped, but they kept me up to date and I didn't plan to start cycling to work until May anyway so this was fine. The email communication was clear and regular. It described each step of the process from manufacturing to shipping etc. so I had a good idea when to expect it as it went along. I took delivery of the kit a few weeks ago, the packaging was totally recyclable. Then, installation was fairly easy and I didn't even need the manual. All in all it took me about hour and a half, but I think if I did it a second time it would be faster. I got a MAX kit and was converting a hybrid 7 gear speed bike. I was able to ride straight after charging as it just worked right away. The ride is really enjoyable with strong power, and it is very enjoyable. The weight on the handlebars did not really change the handling at all, the battery is very small but nevertheless I wondered about this aspect. It's helped me already up many climbs in north Sheffield, what a difference it makes! There are 5 power levels but only level 3 is required even on the steeper hills, 4 and 5 are really strong and I guess drain the battery quite quickly.
