everyone should realize that e-scooters are a physically risky form of transport, especially when driven above about 20km/h.

bicycles have always struck physicists (e.g. me!) as almost miraculous. they are simultaneously:
• dynamically elegant,
• mechanically simple,
• energetically near-optimal, and
• extraordinarily cheap, as a conveyance.YES I DO LOVE BICYCLES. so should everyone, tbh.
with the added proviso that not everyone can ride a bicycle and that's OK. humanity will always need other transportation options. we just aren't anywhere close to bikemaxxing yet and we should be.
@adub I love the hashtag!

@adub It may be that more people than you think can cycle, if you're not already aware of You Can Bike Too. https://www.miltoncountrypark.org/ycbt

@adub In our city riding a bicycle is like renting your lungs to all the air pollutants

@adub we should create save roads for bicycles and there would be many more people and kids who would use them - for most ppl I talked about cycling and everyday use it is not rain or snow that keeps them from using a bike.
It is the danger of other traffic, especially cars & trucks. This is also the most frequent cause of death of cyclists. -

this is so much fun
when the bicycle was invented, there were probably 10 other things people tried - skateboards, etc, and the bicylce survived cause it is the only form that hits all the benefits you mention

everyone should realize that e-scooters are a physically risky form of transport, especially when driven above about 20km/h. if you fall off, you're going to have facial trauma at a minimum. just ask my 50-something brother who got stuck with a big dental bill. ALWAYS wear a FULL FACE HELMET on these things - a bike helmet isn't enough. and NEVER EVER ride with MORE THAN ONE RIDER on board.

The speed and wheel size makes me really nervous.
-
@Wyatt_H_Knott yeah, it would be a mighty steep cognitive challenge for an 8yo to understand that risk correctly. i'll stick my neck out and call it a major parenting fail

@gbargoud your intuition is spot-on

Take it from a professional physicist. (Note: physics is the branch of knowledge involved in road accident reconstruction.)
E-scooters are generally much less inherently stable than bicycles, especially at low to moderate speeds. A bicycle possesses several passive self-stabilizing mechanisms that scooters either lack or possess only weakly. As a result, scooters demand more active balance control from the rider and are less forgiving of bumps, steering errors, and surface irregularities.
@adub But the rider must be part of the equation. I feel like 50 years on skateboards help my command of scooters.
-
@adub Mmm. My school bike, a reward for passing the 11+ and going to grammar school was a 'tourer' with Sturmey Archer 3 speed. It did improve in the VIth form when I got a recon 'racer' with 5 speed derailleur gear, but it was still too hard to be fun. I got a moped instead, then a mighty BSA Bantam.

@kawentzmann oh for sure, being secure on a skateboard helps a lot! i am not an experienced stakeboarder but i can ride a longboard and even that helps

@adub Yes in fact, I count in longboards. I switched to longer decks myself in the 90s and currently have boards of various lengths.

@pthane my first bike had a Sturmey Archer 3-gear too! it was not built for the hill my parents lived on but was great on the more-or-less flat. my next bike was a 12-gear and i could get up that hill in first if i stood on the pedals and (ahem) tacked up the very steepest bit
-
@adub @pthane I see a number of people around my area who don't seem to use gears very well. I sometimes see people pedalling super fast in an easy gear or really slowly in a way harder than necessary gear on flats.
There is of course, a but of preference when choosing a gear and getting a cadence you feel comfortable with, but I've seen what seemed like extremes.
Oh, and grown adults on tiny bmx bikes, which I can't imagine is comfortable to commute with.

@adub How good are e-scooters at doing emergency stops? - just offhand I can't see how they could work at all.

#Cambridge@TimWardCam @adub Thanks for that, Tim. What an amazing selection of vehicles! I'll pass it on to a few pettishly interested people
