    Seem all good up to now, website answered all the questions I had before I made my purchase. I then went on to buy the kit, it arrived within the time stated and fitting was relatively easy and am overall very pleased with it.

    Brought a kit for my wife’s bike and I was so impressed that I ordered one for myself. So far I am very pleased with both kits.

    I use this on my trike and I actually pull a trailer for deliveries. I’m sure I get less mileage doing so, but still have no complaints. I go a full 8 hour shift before I have to charge.

    Hi all. Further to my earlier review I thought I’d give an update. I’ve had this kit on my bike for almost six months. I find the battery holds it’s charge very very well. My bike is a 10 year hybrid and it is a joy to ride and was my main reason going with a kit. My rides are between 50 – 70 miles long. I prefer to use my thumb throttle on hills etc as well as peddling. Great for cardiovascular workout.

    Fab! I now enjoy going out on my bike whenever I can. I like to pretend I ride all the time and this battery may be overkill for me, but the security of knowing I have the extra juice was worth it!
