My partner wanted to smooth out the hills where we are on the edge of the Peak District, but didn't want to change her bike. Then we came across Swytch Bike online. I'll cut to the chase, this is an excellent e-bike conversion solution. Simple to install, easy to operate, and put quite simply, it does the job brilliantly. We ordered the Swytch kit through one of the 'pre-order' campaigns in April 2021. Delivery took a couple of weeks longer than expected, arriving mid-July 2021. Understandable given the current global disruption, and comms were great, so we always knew where things were up to. Once the kit had arrived it took 90 mins at most to fit, including mounting the new tyre, fitting the disc rotor, and sorting the wire routing. This was mainly due to the excellent instructions, both included with the kit and available online. With the battery charged up we headed out for a first spin. The style of my partners bike means the battery is quite high up, raising the centre of gravity. This felt a little odd for all of 60 seconds, but nothing after that. Riding the bike, even on the lowest power setting was a joy. The motor kicks in just enough to give that gentle assist. On the higher settings the assistance is far more noticeable, and certainly makes short work of hills, even the 10%-15% gradients we have tried so far. And on the flat with no motor assistance riding is just as easy. Yes, the bike is little heavier, but not noticeably so, and it doesn't cause a problem. We also opted for the 'black' version of the motor and wheel (as an extra), and pleased we did as it matches the bike perfectly, and if it wasn't for the battery you wouldn't really notice any difference I was slightly worried about how easy it would be to change a tube roadside if the wheel needed to be removed, but having had to deal with that now I can safely say there is no issue. Just have a 17mm spanner in your tool kit. In the end, If I could I'd give more than 5 stars, for both product and service.
