I took a short ride for exercise this morning, covering 31 km in 54 minutes with the velomobile, including traffic lights, negotiating other road users etc.

The Mango is far from the quickest velomobile available nowadays, and mine is fitted with slower puncture proof "winter" tyres because I really don't like fixing punctures in the rain, but for the same expended effort it still consistently goes about 15-20% faster than my road/racing bike or my two wheeled recumbent, a touring model which is a little slower than the road bike.

Add in the low maintenance (leading to low running costs), the weather protection and three wheels making winter cycling much safer and there's so much to like. This is the most efficient transport mode in existence and it's also very practical. It's also fun, of course.

There's a calculator here which lets you work out approximately how fast you can cycle with a particular amount of effort on different types of bicycles, and how much energy is required to do that over distance:

I'm so bummed Recumbent Cycle-Con doesn't come to the West Coast anymore, but at least I can watch this video.

This is my first time seeing a tandem trike!

The centre of the largest telescope in the world* is conveniently situated within cycling distance so on Sunday's open day a group of us cycled there.

You can read more about it here:
https://en.wikipedia.org/wiki/Low-Frequency_Array_(LOFAR)

https://www.astron.nl/telescopes/lofar/

  • It's described as "the largest radiotelescope in the world which can operate at the lowest frequencies that can be observed from earth" and it's about a thousand km wide, which makes it a nice example of peaceful international scientific cooperation.

People crowding around to hear an explanation of how the telescope works. There were a lot of activities going on. This isn't the whole crowd.
One of the low frequency (10-80 MHz) antennas. The high frequency (120-240 MHz) antennas are much smaller and grouped together under the black plastic box on the left of the photo.

On Friday, I had one of the slowest rides on my usual loop this year. 2 hours. Today, the same loop took me 20 minutes less. What changed?

  1. Switched from greased chain to waxed chain
  2. Switched from 1 3/4 inch tires to 28mm One tires
  3. Switched from a (limited edition) pink bell to a (limited edition) pink bell
    Marginal improvements matter!

UCI really screwed things up for ergonomics when they outlawed recumbents in the 1930s.

"The press coverage kicked off a long-overdue conversation about women’s saddle issues and aired one of pro cycling’s open secrets: that some women suffer so much damage to their genital areas they resort to surgery—labiaplasty—to keep riding."

Před devátou a už 275W z panelů. Kafe umleto, uvařeno a vypito. Ponožky schnou. Ale na start závodu do Lyonu je to pořád štreka...

Včera mistr cyklomechanik @cobic odvzdušnil moji zadní brzdu, která už vůbec nebrzdila. A pak jsme trochu popojeli trajektem napříč zátokou.

Does anybody know of a better umbrella term than "non-standard bicycle" for all bikes that are not the "standard" shape? So including bikes/trikes, and other but also etc

Some ideas if nothing exists already:

  • altercycle
  • laterocycle
  • pretercycle
  • teratocycle
  • nothocycle

I want language to talk about how storage infrastructure doesn't include bents, cargobikes, trikes, etc.

Tomnaverie Stone Circle near Tarland in Aberdeenshire. One of 99 "recumbent" stone circles in north-east Scotland, it was built over 4,000 years ago on a hilltop that has since been cut into by a quarry that is very close to the circle. More pics and info: https://www.undiscoveredscotland.co.uk/tarland/tomnaveriecircle/index.html

This recumbent bike was abandoned near my house a few days ago, Victoria BC. Anyone able to reconnect it with it's owner?
Please boost!

Ihr kennt das: Felgenband und Schlauch kriechen mit der Zeit in die Speichenbohrungen, bis die Luft raus ist… Doch das sollte nun der Vergangenheit angehören.

Today's bike ride was the initial outing of the restored Kuifje's Raket (Tintin's Rocket) Quest.

Harry (@twilwel) has been working on this for some time and he's done a great job. It looked quite rough a few months back, but now it looks and works like a completely new velomobile.

Woo! Finally finished editing my video on my recumbent ebike build!

It'll go live tomorrow morning.

Photos from recent delivery runs.

To the greatest extent possible I do my work by human power, but there are limits to how much I can control.

This morning I made a delivery to someone who lives in a village in Drenthe so that delivery was made 100% by human power as I rode there and back in my velomobile.

Parts ordered by people who live thousands of km away are a different story. I can then only control the first few km. So I go as far by bike as I can and then those parcels continue their journeys by commercial shipping companies.

All shipping companies make green claims these days, and they make rather more grand claims than I do. But none of those claims amount to anything close to traveling by human power alone.

Cycle-path vs. "road". We have asphalt.
My bike a few days ago transporting several parcels including a large one in the bike trailer which weighed just under 20 kg. Quite a cumbersome package to carry.
