I love the Swytch kit, not so much the delivery time. It took about 9 months to get my kit (in Canada). I chose this product because I am 72, an upper limb amputee with a 25 year old Raleigh Legend bike that I really don’t want to give up. After finally getting my kit this spring, I got my wife & son to help me with putting it together. That turned out to be easier than expected. The hardest part was adjusting the brakes (nothing to do with the kit). Now that I have my newly renewed bike working, I love it! I can face hills without flinching, never have to worry about being too tired to make it back home from the pickleball court. If they could find a way to shorten the delivery delay, this would be a near-perfect solution. As with another reviewer, I find that the high mount of the battery impedes balance somewhat so I will be working on a way to mount it lower.
