Whishlist - tell us what you miss or how you'd like to improve the Halfbike.
I've been thinking about this for a little bit. I'd like to see a stiffer upper frame (or an option/upgrade to make it stiffer). As I've improved and push myself, I find that if the upper frame were stiffer, my hill climbing would improve, too, resulting in a better workout. I put a lot of pressure on the frame as I'm working hard uphill and I can feel it flexing more as I work the bike.
