It took a while coming due to local lockdowns and results of delays with regards to Brexit but it was worth the wait. The kit arrived really well packed, first impressions were good (I am fussy!) packaging was great, included info and links to web help was also great. The installation was very quick and easy on my Specialized Crosstrail Hybrid. The tyre went on without issues and the wheel installed without having to modify anything or file the forks. After some trial and error I got the PAS fitted, I opted to use the one that has an attachment to fit on to the pedal arm, this was held solidly by some zip ties which were in the kit. My PAS sensor would not fit, after researching on the internet and on the Swytch site I decided to take the mount off and cut the bracket which allowed a perfect fit using the double-sided pad included. I also used two small zip ties for increased security. On to the handlebar mount, the first hurdle - with the inserts, it would not fit, and without it was to slack. I managed to cobble it with some spacers I had printed as a stop-gap, a quick email to Swytch and some smaller ones were sent very quickly. The next job was to tidy up the cables using zip ties and then attach the battery pack for a test. Before I did this I noticed the stitching on the contact cover/hood had come apart, this is not an issue but I was concerned that the contacts were not protected when not in use, again a quick email to Swytch and they are looking into a replacement. The first test was a quick ride around the block, everything went really well, the whole system is very quiet. Just come back from a longer test. I had a full charge and cycled 21.1 km power setting was mostly set to 1 with occasional bosts to 5 for the hills including one very steep one. It's great as it makes you feel like you have still had some exercise and a bot of assistance on hills mean my knees aren't causing issues. I am a real pedal-assist convert. I would recommend it to anybody and to be honest, I am thinking of converting my other bike. Yes there were teething problems but Sytch sorted them quickly ( and to be fair they were only minor ones)
