I've had my kit for a year now so I thought it was the best time to give a good review.

The customer service was great, very knowledgeable and answered all my questions, this is reflected in most reviews and is what attracted me to the company.

I got the bottle kit and it works, you won't get as much oomph as a fully integrated electric bike on hills but that's fine with me as I am now tackling some Welsh hills that I simply would never have been able to without the kit. I have a small frame MTB and getting the bottle into the frame is a little tight, it requires some careful manoeuvring to get it in and out of the holder, especially when trying to get the key in to unlock it but overall, the faff is absolutely worth it!
