Bodymedia and biking

Options
I have a link armband which I adore. I know recording biking is a weakness of all the activity trackers, but I'm wondering if anyone with a bodymedia armband has found a way to record biking.

I've had a few rides where it seemed to record properly (wearing on my arm like normal). I've had many more rides where it records almost no activity (3-4 METS) while wearing on my arm. I've worn it on my calf where it also has recorded minimal activity (but did record lots of steps). I've resorted to taking it off and editing off body time to accurately (I'm assuming based on multiple calculators) record calorie burns. That's fine for calories, but I know riding isn't a constant level of effort (up/down hills, traffic lights, etc.) and I do like being able to see what my actual activity level is. Has anyone found something that worked reasonably well?
