Spring meeting 2017

Eleven of us (plus two dogs) met on the week-end from the 14th to the 16th of April in Freiburg, Germany, to work on the preparation of the upcoming Biketour. The venue was the public café of the housing cooperative SUSI. SUSI is several former military barracks that were bought by a collective using the Mietshäusersyndikat, and association that makes it easier to get a loan for buying houses collectively, while at the same time making sure that these houses can never enter the capitalist real estate market again. The complex is huge, with space for 285 people to live and…

ACROBATICS

In this video the participants try the freakbikes of Radi Vidi Pats in Latvia. Different varieties of tallbikes or a tandem where you cycle face to face are pretty strange cycling-expieriences. Or other balance and body control challenges such as pushing another cyclist with the fully loaded trailer up a super steep hill. Or just turnig in circles.

Picking a circuit for the dynamo-powered USB port

On the Spring Meeting, we did some experiments with different types of dynamo-powered USB ports: Once with a high-dropout DC-DC convertor, once with a low-dropout DC-DC convertor, once with a Zener diode, once with a step-down convertor (an old one, I don’t know which model it is, it cost around 10 €) Once with a double 3300 µF capacitor for boost (as described here), once without Once with a silicon rectifier, once with one made of Schottky diodes We connected these regulators to a Shimano DH-3N30 hub dynamo, and connected a 10 Ω resistor that should simulate the charging device (500 mA at…

Things out of trash and DIY stuff on my bike

The light When I cycle with luggage, I usually have a box on my rack that I can use for stuff that needs to stay dry but easy to access. I particularly use it for electronic devices, there is a small solar panel on it and it is connected to the dynamo charger (more about that below). On the box, there is also an old high-vis that I cut up and wrapped around it for more visibility in the night or in tunnels. On my rack, I have a back light that is powered by the dynamo, but when I pull…

Charging electronic devices in a sustainable way

On the Biketour in 2015, one very noticeable change compared to the Biketours before was that suddenly many people came with a smartphone. In the years before there had been maybe one or two people among a group of up to 50 who had a GPS or smartphone with them, but now there were even some days where no one followed the route of the scouts, because in every small group of cyclists, there was at least one who was using GPS navigation on their phone. One side-effect was that people needed to charge their phones all the time, and whenever…

How to get a group of cyclists into Belarus

As you might have read in our belarus border chaos blog post, getting into Belarus wasn’t easy for us, and our visa application was rejected several times, and then we were rejected on the border several times. When we were preparing the tour, we were not finding a lot of information on how to do this, and the information that we found was often contradictory or simply wrong. Even the border police of Belarus themselves often gave us wrong information or didn’t know how things work. So here is the ultimate guide on how to get a group of cyclists into…
