I like my Swytch bike wheel for number of reasons. It came well packaged and was relatively easy to assemble. It works well and is fun to ride. Perhaps more than anything though it got me interested in old mountain bikes again, which has been a source of great enjoyment this year just gone. I fitted the wheel to a 1991 Kuwahara Tiger.. I think it looks cool. I have two negatives. Firstly, I ordered (and paid for) an alternative mounting kit, which didn't arrive. I was told a replacement part was being designed as the original wasn't considered good enough, which is OK, but I would like to get the battery off of the bars. I haven't heard anything since. Secondly, and this is minor. It simply isn't that fast. I know there are regulations to abide by, perhaps I just ride my unassisted bikes too fast! :-)
