"It's a cute 3D print, but it'd be hard to use - micro-sd cards are definitely a pain to keep track of, I'd say some kind of at least business-card-sized sleeves in a cardfile would be ideal, if you really had to manage a lot of them."

"I have another small-single-wheel trailer, a BOB, it is true that the odd tire/tube size is a little annoying, I would say for limiting the choice of tire more than anything else, so 700c would be a win there. I do think handling would suffer, already having your rig be 50% longer takes some getting used to (esp. in urban settings...) but it might be the tradeoff would still be worth it."

"Looks like the link to their site 404s now, but after poking around a little I see they say coins and other odds and ends are all on the Etsy shop now: https://www.etsy.com/shop/MetonBoss"

"Hmm, aside from the problem of littering the landscape with balloon bits (even if they're relatively biodegradable) is wasting a lot of helium, which we have a finite supply of (and I'd rather have living people get their MRIs cooled by helium than fly ashes around with it...)"

"Came to say the same, there are dozens of BT cassette adapters on Amazon, though none are groovy and transparent."

"Yes, these seem to be a 'solution' for not liking platform pedals, they might work in dry weather, I guess... otherwise most commuters who don't just ride short distances in nice weather tend to settle on clipless (if they can change shoes at their destination), or clips and straps/powertap etc. to keep their feet on the pedals."

"True, though it's not hard to come by scrap or re-used pieces at least (I don't think I've ever seen green before...)"

"I have one, but I find it somehow to be extremely tricky to aim. With a normal surgical-tubing slingshot, after a couple of shots to warm up, it's pretty easy to at least get close to your target. But the Pocket Shot is squirelly - maybe it has some rubbery equivalent to the archer's paradox going on (haven't tried the arrow-shooting version, but under the circumstances I find it scary...)"

"In the night-time shot we can see that the steering is cable-actuated. I tend to agree that this seems like a fairly baroque approach to something that you could do with a cargo bike designed for unfolding over load-carrying (like a flatbed boxbike). I guess it does manage to be quite narrow?"

"It's an interesting array of bags that all look significantly less practical than panniers (I see they do make one or two of those, at least). I have used a frame pack, it was like a sail in windy conditions and didn't hold much without bulging out and clipping my knees, I will stick with the rack and panniers."

"It has potential, but having pulled some heavy trailers, I would say that braking is much harder than moving a big load. If you remove the physical connection to the bike, you'll need some very good stopping power to avoid plowing into the rider if they stop quickly. I can also imagine some gotchas where the lidar spots a possible collision and stops the trailer while the rider dodges around it and doesn't even know the trailer isn't still following (though a the trailer could honk, or ping your phone, etc.)"

"Hmm, it's nice looking, but 2A usb-a is as retro as the cloth jacket on the cord. There are plenty of single gang usb-c pd outlets they could have riffed off instead, which would have actually been useful for charging something."
