Faced withy the dilemma of making a decision between a new e-bike or converting my nearly new hybrid with an e-bike kit, I opted for the Swytch method. Swytch offer a discount to those pre-ordering and as such I was expecting a fairly long wait for delivery. I was pleased and not a little surprised to receive delivery by the promised time, three months - well done Swytch (although some report long waiting times) The fitting is straightforward and well within the capabilities of someone who can do basic bike maintenance. Clear instructions are supported by a number of videos and underpinning this is the offer of assistance by Customer Support. The process went well for me and in a short time my Genesis Tour de Fer was transformed into an e-bike. Riding the bike is great. It really is like a permanent tailwind, or a helping hand. The assistance is controlled and powerful. It works on pedal assistance and can be detected after about half a revolution of the pedals. The level of assistance is controlled via easily accessible buttons on top of the battery pack (in my case fastened to the handlebars and looking like a small bar bag) I live at the top of a significant hill and this has always been an issue when planning rides. No more, the Swytch kit gets me up the hill and no longer is it a leg breaking struggle. I still have to work a little but I now climb the hill more quickly, more easily and in a higher gear. All in all I'm delighted with my decision to go down the Swytch route. I can continue to ride my bike which I love and which is only two years old but which now has the benefit of assistance. I have saved many hundreds of pounds when compared tot he cost of buying a ready made e-bike. A technical problem with my kit was very quickly diagnosed by Swytch Customer Support and a replacement handlebar bracket sent to me within two days. Excellent after sales service I'm happy and would recommend Swytch
