How many days would you like to ride? Based on a formula that includes selected ambient temperature ranges when riding with Aerostich gear, this colorful map portrays a fascinating representation of the annual number of rideable days achievable in cities throughout the United States. Riding everywhere is fun, comfortable, safe, easy and...practical. Do you ride more? or less? Keep track of your riding days to see. 38"x26"
Rideable Days Map Background
The formula for calculating the number of rideable days is based on some simple assumptions about how much time and trouble one might reasonably take to dress for a typical urban-distance ride of about 15 miles. Commuting and errands, mainly. I made those decisions subjectively, based only on my personal experiences riding. The assumptions were then applied to statistics for the average daily and seasonal temperatures in each location, which are all available from US Department of Agriculture to help farmers know what kinds of crops to plant and when to harvest.
The different sizes of the numbers on the map correspond to the populations of the cities listed. In other words, a large number like Los Angeles has a lot of people, and the average low and high temps I arbitrarily used are seldom exceeded there, so this city has lots of rideable days. In contrast, cities like Phoenix AZ and Duluth MN each have different size numbers based on their differing populations, but similarly fewer rideable days because in those places so many days are on average either too hot or too cold.
The specific high and low temperatures (95°f and 25°f / 35°c and -3.8°c) were based on the temperatures I’ve personally found it easy to dress for with my own Aerostich gear. Occasionally I’ve commuted and ridden in colder and hotter temperatures than these, especially when I was younger, those experiences were not particularly comfortable or easy. It’s always been comparatively easy to ride thru temperatures between 95°f and 25°f over my urban distances, which is how those temperatures were arrived at.
Since I subjectively chose the high and low temperatures used to create this map, here's a bit about some related, personal particulars: For many years I've mostly ridden either an unfaired BMW boxer (R80gs, R100 and R1200R), or a Honda 650L or a Suzuki DRZ 400. The BMW's mostly for longer rides and the singles mostly for in-town riding. All have been equipped with electric grips and none have had electric saddles (still planning to add that someday). So if you ride a generously-faired bike with a heated saddle, grips and hand guards, your comfortable temperature range may be a slightly lower, maybe from 90ºf to 15ºf. Also, my regular commute distance is only 3 miles. I motorcycle commute about 100 days a year, walk commute about 90 days a year, bicycle commute bout 100 days a year, and drive a car about 70 days a year.
