You'll both love them.Fantastic. Let us know how the install goes.
I fitted a pair of the oxford heated grips and they just make riding so much more enjoyable at teped temperatures. I have always commuted to work and ridden through British winters and the biggest problem was always keeping the extremities warm and fighting off chilblains. Now it's not problem and toasty palms mean i can ride further in greater comfort.
I'll even use them in the summer time if I get caught in the rain. Sodden gloves and wind chill are no longer a problem. I wish I had changed over to them years ago.
Electric gloves are supposed to be the ultimate solution but at the moment I can use my summer gloves at almost any time of year and it's a really effective cheap alternative which allows me to change my gloves at any time without losing my comfort.
