Slack Randoms: Fixed Gear Skateboard Bikes, Jet Engine Go Karts, Dua Lipa's Shoes & More
We use Slack as our workplace communication tool at Pinkbike and we have a #randoms channel which we use to share an assortment of videos and stories from all corners of the cycling world and beyond... We thought a couple of the moments from the past week were too good not to share with a wider audience, so here are some of the highlights.
Fixed Gear Bike Made from Skateboards
We have seen high pivot bamboo bikes and wooden hardtails but now there is a fixed gear bike made from old skateboards. Not only is it a great use of old boards but it does suprisingly look quite good.

We sometimes call our quizzes 'Ultimate' but this one is pure sadism. Only the nerdiest of shop rats will have any hope of acing it. Let us know how you got on in the comments.

Dua Lipa's Custom Cycling Shoes
To mark the performance of British pop star Dua Lipa in Houston the management at the venue wanted to get her a keepsake. After being tipped off that Dua Lipa was a cyclist, they wanted to surprise her with some cycling shoes during her global stadium tour.
This began a continent-hopping, time-crunched story to create a custom pair of cycling shoes for a pop megastar.

The Science of Braking
 | The Science of Stopping is here to demystify the often misunderstood yet radically important world of mountain bike disc brakes and braking. We all have brakes, but do we know how to get the most out of them? By taking on topics such as the how and why of hydraulic disc brakes, while giving riders context to ride style, rotor size, fluid choice and much more. |

The Climate Spiral
| This visualization shows monthly global temperature anomalies (changes from an average) between the years 1880 and 2021. Whites and blues indicate cooler temperatures, while oranges and reds show warmer temperatures. As you can see, global temperatures have warmed from mainly human activities as time has progressed. These temperatures are based on data from NASA's Goddard Institute for Space Studies (GISS). Anomalies are defined relative to a base period of 1951 to 1980. The data file used to create this visualization can be accessed here: data.giss.nasa.gov/gistemp/tabledata_v4/GLB.Ts+dSST.csv. The "climate spiral" is a visualization designed by climate scientist Ed Hawkins from the National Centre for Atmospheric Science, University of Reading: https://www.climate-lab-book.ac.uk/sp.... Climate spiral visualizations have been widely distributed; a version was even part of the opening ceremony of the Rio de Janeiro Olympics. |

Thankfully Spotify means I can spend all day listening to Nirvana, Pearl Jam, Greenday and cheesy 80’s music that takes me back to school discos .
Ill get my youngster ears on and play a bit of Radio 1 rather than 4!
I wanna have a beer with Mr. Maddox and just listen to and watch this thing over and over. Looks like something built out of a Mechano set but makes real fire and melts steel and goes really fast. Only thing better than this is if Morgan Freeman did the voiceover...but only because Bob is driving.
Even though he technically stayed upright on the bike I don't know if I'd call that "riding", more like froggystyle.
