Guys, I appreciate the comments and advice but I'm not giving up just yet. My reasoning is:
- I really want to keep the bike, and now I'm exercising again I'm hoping to regain some strength (and I'm going to plan a long walk into my days in future, too).
- I had exactly the same bike-drop with my R9T - there are some tight maneuvers on my patio. Frankly, it doesn't matter if a bike is 500lb or 700lb... if it's going to go, it's going to go.
- It's too early to give up this particular fight, although I'll review the position in a couple of months. As it stands, though, my April trip is still on.
