riding my bike yesterday and hit a top speed of 27mph. pure joy as I was moving through the wind at what felt like mach speed bikes contextualize speed. when you know what 25mph really feels like you understand that driving a car within city limits in excess of 25mph is pure madness yeah #fuckcars

For my non-cyclists friends, you get some sense of speed by standing close next to cars flying past you. It's not the same but this exercise does highlight the absurdity of speed in cities.

I’ve gotten close to / above 40mph downhill a couple times and let me tell you our brains did not evolve to process that kind of speed
Avatar
yeah 40mph would be a rush. I'll work up the courage to do it eventually and when I do it'll probably just make me more upset cities allow those speeds next to sidewalks.
Avatar
That’s exactly what it will do. I don’t go that fast anymore. Mostly wanted to see what it felt like. Also my wife was NOT happy.

I'll wear a mips helmet! And yeah, I bet she wasn't. 40 does seem like a lot. It's interesting because a 10 mph difference seems like nothing in a car, but 30-40 mph on a bike reveals just how much a leap that is. Again bikes contextualize speed.

Curious, what was the stopping distance like for a bike going 40mph? Asking as I definitely would not try myself lol
Avatar
I didn’t have to come to a hard stop, I started feathering as the hill leveled out well ahead of the light. But that bike is a cargo bike with Serious Disc Brakes too

200kph in a Blutec Mercedes on the Autobahn.

yeah having gone 40mph on a bike it _really_ means something a whole lot different when you’re not in a metal box (thanks 7-10% grades)

I haven't been brave enough to speed down a hill like that yet but I'm sure I'll be back with a whole new perspective when I do hit 40. Cities in the US do have 40mph speed limits next to sidewalks (with motorists going 45+) which is absurd but just how absurd I will just have to find out soon!
Avatar
Oh yeah, it's really freaking wild to experience. I only knew I was going that fast because the speed control sign clocked me at 37. Otherwise my brain was 100% focused on ensuring I didn't fall down and explode.
Avatar
Oh I bet. I only caught glimpses of my speed because I was more focused on riding. Another 10mph is going to be something.
Avatar
Totally. I was going 40km/h downhill today (speed limit 40) and I was reminded that it’s very fast - even though the driver behind me wanted to pass
Avatar
that's super irritating. passing at those speeds (especially when what they're wanting to do is speed) is wild. and I know that behind the wheel it's difficult to understand just how fast you're going, so it's not entirely on the motorist. this just shows how important good street design is.
Avatar
once got passed while going 10mph (45 in a 35) over the speed limit (steep downhill). some drivers are physically incapable of comprehending a bike going the speed limit or faster
Avatar
Avatar
they passed me with like 3ft room too... but flipping the driver off was a bad idea, i got brake checked. closest i've come to actually punching out a driver (chased them down the hill but the light at the bottom was green)
Avatar
yikes. motorists do dangerous stuff and sometimes it's because they don't know what it feels like to be a pedestrian/cyclist near that kind of action, but sometimes it's because they genuinely do not care about your life. both are scary. I'm dumb too sometimes and also reveal my discontent
Avatar
Maybe they were just offering a motorpace
Avatar
it’s totally not a competition but sunday… at a certain point you spin out (52x11) and just have to tuck in and let gravity do the work
Avatar
wow, impressive! This is on a nice aero road bike? I don't know where I'll top out at but I'm slowly working up my confidence to go faster downhill.
Avatar
yup an allez sprint w/ 50mm carbon wheels. i don't hit that much often - this particular hill is basically just straight & downhill (with a big turn at the bottom i've not tried hitting at that max speed, i brake pretty hard into it down to like 40 or so)

extremely nice bike. that sounds like a ton of fun. I have a relatively light ebike (36lbs) that I honestly use as an acoustic bike most of the time, but I'm considering getting a normal road bike too though doubtful it'll be as nice. one day I might reach this level. how long have you been riding?
Avatar
started (well, riding seriously) when i moved to boulder, 6 years ago? this one was a replacement for the 2010 madone (bought used) i crashed in 2020
Avatar
allez sprints are fancy race bikes, but they're aluminum so not horribly expensive! think the new ones are $2100 or so (vs the $1500 i paid for frame). i put di2 on this but honestly could put 11spd mech 105 + some fancy wheels for ~$4k all in? compared to like $7-8k for the tarmac
Avatar
It's insane that the maximum speed most ebikes are legally allowed to go is also the minimum speed 2 tons of steel operated by idiots are expected to move through residential neighborhoods
Avatar
Avatar
Knowing that falling off bike and slamming into the concrete/ground at even this speed would be painful and potentially harmful contextualizes everything. And yet hitting a pedestrian with a car at 30mph has 50% fatality rate, and you feel like you're barely moving. Cruelty baked into infra
Avatar
5mph increments in a car feel like nothing, but as we know 5mph can change everything if you're outside a car. Cycling provides a good measure of speed that is even hard to get a feel for as a pedestrian (though perhaps running provides insight? I dunno I don't run) But yeah the fear of falling 😱
Avatar
This reminds me of when I was a new motorcyclist, riding on the highway with the tarmac flying by under feet at 75mph...
Avatar
That sounds fun as hell but hard pass that ain't for me.
Avatar
I dunno about fun, I'm not much of a speed demon (I don't get the endorphin kick). But it highlit not-in-a-metal-box reality of the speed I was moving.
Avatar
oh I'm sure I don't even have an idea what that would feel like
Avatar
I think similar to your 27mph on a bicycle. Kinda scary, but you gotta keep your shit together or you might crash!

Same but a bit different for being in an open convertible or in a car with windows down
Avatar
low-key if I'm ever forced to buy another car I really want it to be a convertible.
Avatar
when i rent a car in brooklyn im always like shouting at other drivers for going over 25mph and i am always shocked at how bad the blindspots are even for small cars like priuses and sedans
Avatar
the blind spots are a huge deal too because while a car is less likely to not be seen given their size, pedestrians and cyclists are significantly smaller. we should really work on minimizing blind spots on cars
Avatar
even the small cars have such large blind spots. and american cars + american streets are so bad. why are our cars so large in urban settings? they should be tiny.
Avatar
it's one of many perplexing American mysteries

To further blow your mind learn about hydraulics and how pressurized fluid in tubes is what everyone is relying on to STOP their 2,000+ lbs of steel.
Avatar
do I really want to 😱 my bike has hydraulic disc brakes
Avatar
Yeah, but those are only stopping 200 lbs!

The thing that often really drives it home for me too is when I'll be going fast 25-30 mph and a car absolulely BLOWS by me on a narrow road.
Avatar
40 years ago I could run quite fast. 3:56.9 for a mile, so just over 15 mph. You would not want to run into an immovable object at that speed. You would be going to hospital to be put back together. & that’s 15 mph! Meanwhile, on the gravel bike… 😅
