After a longer-than-expected wait (COVID) between my Indiegogo support and delivery of my Pro kit, I am very happy with how it transformed my daily and trusted bicycle. My main motivation was to upgrade my now 5 yr old bicycle which I specced with a single gear hub. It's now ready for more years of carrying kids, groceries and myself around. Installing the kit was a couple hour job, changing the tyre was the most challenging part (that says a lot about the ease of the rest of the steps). And I love the fact that I hardly notice the kit is there when I choose not to use it (and leave the chunky battery home). Owned it for 2 months, used it for about 100 miles.
