Dress warm, studded tires. People are so averse to any non ideal weather for cycling. Texas, Arizona and Nevada people say it's too hot, West coasters say too much rain, other places say snow and ice. All excuses that can be solved by better personal preparation mixed with safer better maintained cycling infrastructure. https://m.youtube.com/watch?v=Uhx-26GfCBU

Infrastructure and prep can do a lot for cold and ice. But unless we're installing locker rooms everywhere, it's less helpful for rain and not at all helpful for sweating in the heat.

You do you, I personally would never bike on roads I would hesitate to drive on, which is what we have here in the winter, especially not an ebike that is going as fast as a car but without any of the protections, in traffic with cars and trucks that will run right over me if I wipe out on some ice.

Exactly, which is why we advocate for safe, separated, regularly shoveled bike lanes.

I’ve biked to work in -15C. Get studded tires.

The vast majority of the population is simply not going to do that if they bike at all.

See what happens in other countries. Are they just tougher?
