OUCH! Best of luck to you on your recovery.

I've been through the pevlis-broken-in-3-places thing, so I have an idea about what pain you have. Recovery (including walking again) was a long, hard road. Listen to your body and you'll be fine.

I was really worried about biking being too painful for me after the pelvis breaks, but it turned out to be painless! (ok, so I am riding full suspension mountain). So hopefully biking again is something you can look forward to.

As for the wheelchair - I used a wheeled desk chair for getting around the house. WAY easier. Just push with your feet (this means you will be traveling backwards). But this meant I could fit in a bathroom with my desk chair and use the toilet instead of the chair potty. (I was allowed to stand and pivot on one foot since all of my breaks were on one side).

Heal well.
