I ordered a Swytch kit Air about a year ago. Took about 4 weeks to get delivered to Australia. I asked a few clarification questions before finalising the order and they were answered promptly. Install was straightforward enough but getting the pedal sensor mounted was the most difficult and cable ties and double sided tape was never going to be a reliable solution. Removing the pedal arm and securing to the crank was a much better and more permanent solution. It’s been working trouble free since mounted this way. Riding experience is very good although the Air battery will only last over 10kms if used on the lowest assist and you don’t encounter too many hills. Hills and higher assist levels will chew up battery a lot faster. Turning on/off the power as required conserves power for when you need it. Overall it suits my style and capabilities 100%.
