Removing roads decreases congestion: Braess' paradox

Roads for private cars are generally overbuilt and run directly into Braess' paradox. E.g. Five years after Sepulveda Pass widening, travel times on the 405 keep getting worse.

That's great to know. I'll keep that in mind when I need a new set of tires.

Not taking advantage of free street parking is crazy. Think of all that extra storage and space in your garage when you don't have to park in it!

Only 500Wh with two tanks? That's, at most, parity with a single lithium-ion battery e-bike; for the same weight too.

The 38 tires should really help on the rougher paths. Maybe I'll pick them up when I wear out my current set.

I haven't tried the front rack yet. Not out of dislike but because I usually pack nothing or way too much. 🤣

Same goes with fenders. I haven't installed them, and probably won't. It's too sunny where I'm from.

The frame is made in Vietnam. The quality is alright, not amazing but certainly appropriate for the price point. No issues with it so far and better than some frames I've seen from the PRC.

It can roll without a rolling rack, but not easily. Good enough for a few feet here and there. I suggest going for the rolling rack if you want to push it around train platforms and such. The saddle is padded on the underside though. It's nice when going up stairs.

One more thing: the drive train is exposed when folded. Watch out for dirty chains and be careful when loading it into a car. It's easy to damage the derailleur hanger or disk brake if it tips over. Support the bike with a box or tie it down when transporting it.

FYI, these are speed cameras, not red light cameras. They're set such that you'd need to be doing 36+ mph in a 25 mph zone.

I own a Tern Verge D9. It's a functional and sporty folder.

The Verge is a snappy feeling ride. Think road-bike handing. The tires are also good, but at 30mm it won't like anything rougher than hard-pack dirt. They're also ISO 451, not the more common 406. This size has fewer tires to choose from for a slightly nicer roll. It's up to you to not if that's a worthy hassle.

FYI, the magnetic latch is terrible. You will have chipped paint on the fork. I don't mind but you may.

Careful folding and unfolding. The stem fold likes to bite the brake and shifting lines. That will screw up shifting.

The matching rack they sell uses oversized tubes. You may need to replace the hooks on existing panniers. Also the racks sits closely to the pedals, so large things may have some foot overlap.

I'm sure I have other thoughts floating around about the Verge D9. Ask anything you'd like to know about it and I'll try answering.

The southwest of the US gets really hot for long periods of time. For example, Pheonix Arizona has four months of the year with a daily mean temperature above 30 C and highs around 45 C. Pheonix is also part of the Sonoran Desert, meaning water itself is hard to get. Running a water tap for minutes to fill a cup of mildly cool water is deeply frowned upon.

It's unpleasant to say the least. Although the heat is not as bad as the rumors I hear about Finnish mosquitoes.

I'm bad at following instructions. Here's several tips. :)

  • A washing bag (e.g. Scrubba). The bag and a dry bio-compatible laundry soap weighs the same as one pair of wool socks. Using it means you can cut out underwear/shirts/socks bulk for a slightly higher camp chore load. Very useful for weight/space sensitive camping and doubles as a dry bag!
  • Prefer good clothing over sunscreen (big hat, long-sleeved shirts, buff, sun gloves, etc). It's lower weight, less greasy, and doesn't run out. When using sunscreen, stick form tends to be light and easy to pack.
  • Camp shoes. Always bring them. Crocks, thin flip-flops, anything but a tight shoe that you spent the last 12 hours in.
  • Avoid cotton in general, but also look for quick-dry clothing. Being wet sucks. Being wet for long periods of time can be dangerous.
  • Umbrellas are amazing. Shade when there is none and amazing at avoiding wet-out. Very useful for short trips and car camping, though I sometimes bring it backpacking even with the added weight.
  • Light (1lb / 0.5 kg) camping chair. If you're young enough you could skip this, but my god is it worth the weight after a long day.
  • Wear warm clothing in your sleeping bag/quilt. Bag ratings are inconsistent, often assume you're wearing clothes, and are labeled for "won't kill you" rather than "you'll sleep like a baby."
  • A good sleeping pad with a solid R value. It's as important as your top sleeping layer.
  • Dry electrolytes, especially in warmer areas, like SaltStick or Gatorlytes. Hypotonic dehydration can sneak up on you and you cannot escape it by drinking more water. This is particularly dangerous with aerobic camping, like backpacking or bikepacking. Hypotonic dehydration can be mitigated with the food you pack, but it's a lot to plan ahead on and complicates re-hydration with caloric intake. Do not avoid high-sodium foods unless your doctor has you on a low-sodium diet (in which you should also discuss with your doctor about your outdoor activities).
  • Sleep with your electronics. Cold weather will kill your phone's battery.
  • A portable bidet (e.g. CuloClean). There are many places where you must pack out TP (sometimes everything). Less TP means less to carry in and out. It's also very clean feeling.
  • Similarly, WAG bags are nice. Zero trace and you don't even need to dig a cat hole.
  • Ear plugs. Nature is loud sometimes. People in campgrounds are even louder.
  • A small towel or sponge to wash with. It's nice to wipe off sweat and dust, even if it's not as good as a full shower. It's multi-purpose too. Moisture on your single-walled tent? A quick wipe and no indoor rain for you.

Come to the southwest during summer where taking a shower doesn't involve the hot water tap.
