Delivery was in the expected time frame. The bike this was added to has a lot of stuff already, so the fit was a little difficult. The main issues I had were fitting the thumb throttle around my CI Deck shifter and getting the disc brake to fit. The instructions aren't clear on either but the trouble wasn't difficult to work out. Part of the issue was inside the shifter itself. A couple more things I noticed: on some freewheels the bike pedals spin backwards if you push the bike backwards. Be CERTAIN you have or can obtain a cassette if you get the Max. Also the Swytch hubs do, IMO, have quite a bit of rolling resistance to them. It's similar to that of the electric wheel on an e scooter. That resistance is constant and the kit itself can overcome this on the lowest setting, but be aware of it if you're used to absolute zero resistance on the rim you're replacing. As for the ride, it honestly feels like I'm constantly on the brakes. Above level 2 it takes all the resistance out of the pedals until I hit 25 MPH or so. At that point I can start to feel my quads and glutes pulling along with the kit. I'm good for 29 MPH unassisted on flat ground with a standard rim and no wind. I also noticed if I go through a number of gears, as you should when increasing speed on aulti gear bike, the power assist drops slightly after each gear change, even through the rated speed range of the kit. It seems that the kit likes to seee start out in a much higher gear than usual. Overall those are just observations and I would highly recommend the Swytch kit with two caveats: One, get the best battery pack at the outset. Two, you *will* still be pedaling a bike with a Swytch kit, but isn't exercise part of the reason why we ride anyway?
