Ordered a Swytch Go with the middle-sized battery pack. Delivery should have been June, but it was a month late. The kit was fairly easy to install. Only 5 rides with it so far, but it is easily giving 20+ miles, moslty on 1 or 2 out of the 5 power levels, and the battery still shows 2-3 bars out of 5. I'm quite a fit rider so I do notice the drag when trying to get past the top speed. It would be nice if there was a clutch to help remove this. I suspect in reality the battery will probably give the quoted 30 miles range, but I'm sure the last 2-3 bars will drop off at a faster rate. The wheel seems well-made, but I wouldn't want to use it on anything more off-road than a gravel path. It would have been nice to have the option of a black rim/spokes, and I would have paid an extra £20 for such an option. I hope the kit will give me 2 years service (2-4 20mile rides a week). If it lasts less than that, then I'll try a full e-bike next time.
