I honestly don't know if I've ever ridden in 110F temps. But I'm pretty sure I've never said no, I can't ride because it's too hot. When you're on the bike, that air moving around you feels really good, even when it's hot air. Coming down off the Queensborough Bridge the other day, I believe the air temperature, with the sun beating down on the asphalt, must have been well over 100F (but what do I know). It felt like I was riding into an electric hair dryer. And it felt good. When I got the my train station and stood on the platform, there was no air moving and I was dripping with sweat, and that did not feel good. When I got on my air conditioned LIRR train a few minutes later, the cool air felt wonderful for a few minutes, and then I put on my fleece jacket. Summer is weird.

I'll agree at 50 below I would find other options, but 100+ can be a real problem for those not acclimated to it.

to me, bike commuting in 10 F - 20 F is a little hard but not impossible. 20F - 30F is easier, nice and cold. 30F - 40F is perfect. 40F - 50F also perfect. 50F - 60F also perfect. 60F - 70F is nice and perfect. 70F - 80F is OK. 80F+ is hot, but do-able in that i have to slow down. i haven't cycled in weather below 5 F and also not above 95 F but if the weather goes there, i will go bike anyway and just be more mindful of myself and my body's tolerance i guess.

Warmest I've ridden was a couple summers ago at 108 F. Put on about 40 miles that day. My normal commute is about 16 miles round trip, but I was trying to set some mileage goals so I did a 10 mile leisure ride over lunch and then took the long way home from work.

Coldest I've ever ridden is -14 F. That puts my total riding range at 122 degrees.

Normal high for a summer day here is in the upper 80s to lower 90s. We'll break 100 a handful of times every year but thankfully we don't have to deal with those temps day after day. Now sub-zero temps in the winter are a completely different story...

I was in Sioux City, IA one winter (maybe 1995) when the temps hit -40F with a wind chill of -70F. Now that's friggin' cold!

Sioux City is about 90 miles south of Sioux Falls. They're warmer than we are.

And the people up in Thief River Falls, MN would consider Sioux Falls balmy.

What really stops me more than the air temp is the wind. Living in the great plains region, a calm day is truly a rarity. 30 mph winds are fairly typical and we really don't raise our eyebrows too much until wind speeds break the 50 mph mark. Combine those kinds of winds with sub-zero temps and that's when things get dangerous. At that point I throw in the towel and drive to work.

40s is long sleeve weather, and probably leg warmers, that's about it.

My clothing doesn't start to get really serious until about 5*F. At -5*F I have to have a neoprene face mask and start being very careful about sealing all cracks in clothing on my face to avoid frost nip.

I rode when it was 98F once (7 miles one way). Not fun at all, especially stopping every mile or so to douse myself with water. Bear in mind, this was with high humidity too. We don't get "dry heat" here in PA. I have no problem riding down to around 10F, but I don't think I'll do 98+ again.

Warmest I've done is 105*F. In Michigan, it was pretty damp as well. I guess I just like warm weather because I've been sad it hasn't gotten that warm again lately.

Definitely! I had 25 years in Michigan and was fine with the cold. After 10 years in Phoenix, when the temp drops to below 50, I stay inside but have no problem with the higher temps. It's all about what you're used to.

Been doing it all week with heat advisories here in FL. I am actually sweating enough that when I look down I can see sweat falling off me onto the road.
