I LOVE my Swytch kit and it has made a world of difference to my biking adventures. At age 75, I am very fit but when you have only a 7 speed lady's cruiser, having the electric assist is like magic. AND, while the rear wheel is a bit heavy for me to hoist my bike up on my car rack, I back up to raised curbs when available (at my residence) and use stepping stools to rest the bike on as a halfway measure and then I can get it up and over the arms of the rack. (my rack is portable and fits over the back window and tail gait of my Subaru Outback Wagon.) I have not found the battery on the handle bars to be too heavy to balance and in fact it seems to even out the weight on the bike overall. Some electric bikes have everything in the rear of the bike, making it impossible to lift. Everywhere I go, I get comments and inquiries. Of course the price is right as well. Thanks Swytch, I love clever designs and thinkers and you are certainly that!
