I am very pleased with my swytch bike. I am a 56 year old non 'bikey' grandmother and I must admit I was a tad daunted when starting my conversion - however I followed the instructions and got the conversion done (it did take me a couple of hours). I was however blown away when I did my first test ride and found that it did actually work. I have used my bike about 10 times - the longest trip being a return 14 mile trip to visit a friend on a train strike day. It is great. I probably should also read the manual as I'm not sure what I should be doing re gears and powered assistance however I seem to be getting by ok. I generally have the lowest power level until I have a hill and then increase assistance. My bike is quite old so I have felt ok leaving it at a train station as it doesn't look like an electric bike. I do carry my battery with me when I leave it.
