Hi Avi,
Wishes for a highly successful surgery this Thursday, and a good recovery. I was bilateral as well - also 1 month between surgeries. I'm now a year and a few months post op, and everything is fine. Post op recovery goes pretty quickly in many ways, but it is a major surgery with cutting and stitching of muscles, and some things take a long time to get all better. But for that reason, I'm very happy with my decision to have the near-proximity bilateral. It would be a bummer to get to the point I'm at now, and then go back under the knife to get the other side done.
Re cycling: I used the equipment I had: my roadbike and training stand. My surgeon advised easy spinning as soon as possible, so I was on my bike 7 and 10 days after my respective surgeries (if memory stands).
Mounting the beast was a challenge, but I got help from my wife or kids for the first month or so. At the very beginning, I'd pre-clip shoes into pedals, use a stool, and have a helper to steady me and help swing my leg behind the seat and velcro my shoes shut. I started with no resistance for a couple weeks and gradually worked in resistance. I've forgotten the timeline, but I remember the accomplishment of getting on and off all by myself. The good news is that after a while, you'll be able to get your leg over the top tube with much ease with your shiny new resurfaced hip.
