Tuckervill: My feet bounced a bit on my cage style pedals, but have never come all the way off. While I don't ride off road, I'm not a particularly aggressive rider and platforms will likely meet most of my needs.
Yes, I imagine on a recumbent you're not putting your weight on your pedals like we do on mountain bikes.

I pretty much believe that if I hit something hard enough to bounce my foot off the pedal, something bad is already happening and I'm doomed anyway. lol.
