It isn't the weight - it is the different geometry with trying to get a 3-wheeled bike up my stairs, and then trying to transport it. A trike won't fit my expensive bike rack, and I've enough of a problem getting my Gunnar into the back. I've not yet decided, but we will see. I want to give the Gunnar another chance this spring, and I DO have a lot of other fitness activities that I can do with relatively little repercussions if I am smart about it.
