I did ride just a bit longer after I fell over and it seems that I might put the cleats on the back mounts and give them a try there. Also going to practice getting out of the pedal on the up side (leg bent rather than extended like I did when I was riding my DF). Seems to be harder to unclip with my leg extended.

The wife could not believe that I fell over riding the recumbent.

Have put together a kit with large bandaids, gauze pads, tape and ointment. Going to make up another one so that I have one for each bike.

Edit - went out this morning to check on the spring tension. Found out that the left pedal was set quite a bit higher than the right. Corrected same.
