It will be in the single digits but I got to try. My normal cut off is usually 20 degrees or less but he can do it so can I.
I've been in that same position. It has helped me have very few reasons to drive to the office*; it got to the point where the only reason I would not bike to the office was for off-site meeting or a commitment right after work.
Another motivating factor, I use Strava and many of my local bike-commuter friends use Strava too. When your eating breakfast, see the temps is below 0F but your Strava feed is already full of people's morning commute, it makes me say "OK, I can do that too!" Peer-pressure.
* I moved to a home office last year. It will sound odd to many, but I miss this cold morning commutes. I still get out and ride daily, but my schedule keeps me at the desk until mid-morning (gotta make all my social media posts, y'know).
edit - afterthought: just check my Strava feed, at 8:15 AM and 1F, I have 5 friends that have biked to work so far today. Distances range for 3 to 18 miles.
