witnessed a bike crash

Decided today to go to the Drexel Museum of Natural History. But Avi was interested too, yet couldn't go today. Decided on the Weitzman National Museum of American Jewish History. Close enough to walk to, if I wanted a brisk 20 minute walk in dew point 20 C weather. Easy bike, but taking my bike raises concerns about leaving it locked for hours in Center City. So went to Indego bikeshare, and an ebike, partly because that's all the station had. ( Read more... )
The pricing of Philadelphia's bikeshare program is pretty weird.
One ride? A whopping $4.50 for 30 minutes; extra $0.30/min if you go over or use electric. Bus fare here is $2.50 and gets you free transfers.( Read more... )
I previously mentioned seeing the lowest recumbent trike I'd ever seen. A day or two later, I passed the highest recumbent bike I'd ever seen. Definitely a bike, 2 wheels, which looked about as big as the 20" wheels of my folding bike. Obviously they're usable, but I have no idea how you mount or stop such a bike, at best it looks like you'd have your leg at a very awkward ankle.
I've been indulging in hot chocolate recently, and realizing it actually costs money. Like I just got some peppermint hot chocolate form Trader Joe's, and it's $6.50 for 8 servings (not counting any milk added), something like 80 cents a serving. An earlier variety was maybe $5.50 for 10, still 55 cents each. On Amazon I see other expensive ones, even over a dollar per.
I also see Swiss Mix, "milk chocolate flavored", for 10 cents a serving. I guess the difference is whether the ingredients list goes "sugar, cocoa..." or "sugar, corn syrup, whey, cocoa..."
Chocolate can counteract the bitter flavor of Bitrex in mask fit testing. I plan to see if sipping hot chocolate works as well, or better.
I now have a new Tdap shot. I'd accidentally gotten a Td shot 2 years ago in Canada; I hadn't known there were different blends, so went in asking for "tetanus" or maybe even "Td", in all ignorance until afterwards that I wasn't getting a pertussis booster. Finally fixed that lack.
Not very deep, but a short video on the virtues of garbage/beater bikes. I'm in the category of people who have only owned a fairly cheap bike, though not garbage. I am reminded of advice I saw once on how to get bikes while moving around between cities: just buy a really cheap one, and sell or abandon it when you leave... Though safety, or having luggage baskets, are another matter.
Place vs. non-place in urban design.
OSP history videos on Cyprus and Sicily. Apparently Cyprus stayed literate through and after the Bronze Age Collapse, and Norman Sicily was a great ferment of multiculturalism, with Muslim scholar in court and coins with Arabic as well as Greek or Latin text.
Certain people on Twitter and Bluesky, along with my own observations (like crossing Ashby or University, or the Hopkins bike lane fiasco) have given me a low opinion of bicycling in Berkeley. But for the first time today, I tried biking toward campus beyond Ohlone Park, first to check the Downtown Farmer's Market, and I have somewhat more nuanced opinions now. Somewhat.

Some people have worried that using an e-bike means getting less exercise, since the motor assists your pedaling. Apparently multiple studies have found that yes, there's less effort per time, but people with e-bikes spend more time biking, for a larger total amount of (moderate) exercise.
I suspect there's something similar with my (acoustic) bike. I generally use it as "better walking" without really exerting myself often (except where slopes and gravity force me to), and with all the gentle slopes around here, a fair fraction of the time I don't have to pedal at all. But it's getting easy to be out for a few hours, with only my tailbone complaining (and maybe it's finally giving in?) whereas between 90-120 minutes of walking in a day tends to make some joints and muscles complain.
I'm also finding that I've gotten used to the speed, and walking can seem painfully slow...
Revisiting yesterday's post in American units, since I mostly want to persuade Americans.
Thesis: low-density living, with single family houses and sizable yards, is compatible with low-car if not car-free living, if you go in heavily on bicycles.

I've touched on this issue before, not all that long ago even, but I feel it deserves multiple angles. ( Read more... )
For the first time in 7 years, I own a bike. For the second time in 7 years, I've ridden a bike. (First time was a rental in Vancouver.) I'd thought about it for a while now, but with my constantly hazy future, I never wanted to commit -- certainly not to the $660 new bikes down the street that I might have to abandon when going nomadic again, or commit my life to really cheap Target bikes, and I never got around to seeing what was on Craigslist.

I thought of a new angle on just how badly most modern cities have let people down by not enabling safe biking.
Most cities have at least some bus service, whether as a semi-credible public transit system or as a sop to the poor and elderly. How fast are these buses? Pretty slow. NYC buses rarely break 9 MPH / 14 KPH though they're especially slow. City Observatory has easily-graphable data for multiple US cities, 2000-2013; the mean and median are 13 MPH / 21 KPH, big dense cities I'm familiar with are more like 11 MPH / 18 KPH, and very few cities break 15 MPH / 24 KPH. Absolute peak in the US was Salt Lake, almost hitting 19 MPH / 30 KPH for a few years. Even BRT systems around the world rarely break 30 KPH.
Bike speeds vary a lot, but en masse, one source says Dutch riders average 17 KPH. From my experience, it feels hard to go under 15 KPH and stay upright, even on a thick and heavy bike. [Edit: this says 12.4 KPH for the Dutch, and now that I have a bike I see I overestimated my default speeds. I don't know if either Dutch figure is "speed of motion" or door to door "speed of travel".] So being able to bike is like having personal bus-speed service, without the car necessities of a driver's license, insurance, and thousands of dollars per year spent on a car. (Or social cost of the 40,000 lives a year lost to cars, pollution, noise, etc.) Even if buses go faster than you do on a bike, not having to walk and wait means bikes win up to some distance.
Let's do an extremely bus-friendly case. Bike 15 KPH, bus 30 KPH, average of 10 minutes walk and wait to get on a bus. They cover equal distances at
1) 15*t = 30*(t-1/6), t = 1/3 hour, distance = 5 km
. So for trips under 5 km or 3 miles, biking is faster.
If bus speed is 20 KPH and the time is 15 minutes to get on, we have
2) 15*t = 20*(t-1/4), t = 1 hour, distance = 15 km
.
And this has been assuming that your destination is right at your bus stop; in reality there's potentially more delay there. (Also assuming bike parking right by your destination.)
Note what this means for a city planner wanting to reduce car use. You could invest a lot in public transit, including the high capital costs of metro or the high labor costs of frequent bus service... or you could shape your infrastructure so that lots of people view biking as safe and convenient, providing their own bikes (at a few hundred dollars/year) and labor, with your main job doing sweeping and snow removal.
But of course that low financial cost comes at the high political cost of taking street space away from cars. Easier to drop some buses in and call it a day... easier, but not very effective.
This post owes a lot to this kchoze post, on why buses have low mode share in Japan, and arguing buses have little role in a well-designed city (one with good walkability and metro, not to mention attractive biking.) I'd urge you to read the kchoze as well.
