I’ve been using bike all Summer and I’m really pleased with the conversion, a great help as I live on a steep hill and setting off with cold muscles was getting difficult for me. Customer service advised me on the Shimano PAS which is a very neat and tidy fitting, but I did need to buy the correct crank remover from a local bike shop at £18.. The kit turned up ahead of the forecast date, Conversion was easy, the front end of bike is a little heavier but not detrimental to the bike handling and means that my lovely bike has a new lease of life. 5 stars for Swytch!!
