Having tried out two e-bikes several years ago, we'd entertained the idea of a possible purchase sometime in the future. However, the biggest stumbling block to our plans were that we both owned bikes that we were loathe to abandon so the idea of a conversion kit grew more appealing as the years ticked by. Having discovered Swyche, and having read the various reviews, we duly put orders in, and the two boxes arrived in early October. I purchased two install kits, the PRO versions. The installs were fairly straight forward although I did find the website a bit confusing to navigate, what I wanted was a comprehensive set of instructions at the front of the web pages. Also, the 'quick install paper instruction' seemed unnecessary, let's have a full set of paper comprehensive instructions supplied with each kit. Unfortunately I received the wrong sized wheel for my wife's bike, 700c, not 27". They initially agreed that I could use the 700c wheel providing I could fit it and they would order the correct size asap. I had to buy a new tyre to fit the 700c wheel and by minimal adjustments to the brake, my wife was able enjoy her bike. Swyche then contacted me and offered a refund instead of the correct wheel which I accepted as I decided to upgrade the back wheel also. This would mean I could obtain new tyres if necessary when cycling abroad. The only other problems were the pedal sensors, the ones supplied are too big and are apt to move out of alignment. I have managed a slight temporary modification, but am awaiting two new alternative sensors. In terms of how they work, we are both thoroughly enjoying the benefits of a Swyche conversion and have racked up 500 Kms between us. We are very pleased we took the decision to convert our much loved steel framed classic touring bikes. Both bikes, a 30+ year old Carlton Courette and a similar age Raleigh Royal, with the kit fitted weigh an almost identical 19kgs so still competitive weight wise with much more expensive modern offerings and still offer a very decent riding experience when cycling without e bike power.
