Avid followers of our Raspberry Pi Twitter account may be aware of just how bike-loving the residents of Pi Towers are. From the weekend cyclists to Cambridge-London-Cambridge racers, the flat land around our office calls us to jump on a bike and explore the fenlands.
In celebration of #CycleToWorkDay, we’ve brought together a collection of some of our favourite bike-themed Raspberry Pi projects, perfect for those of you who enjoy a bike ride — or a pint!
Bicycle-powered beer dispenser
The Glaswegian company Bright Signals was tasked with a tasty project: create something for Menabrea that ties in with the Giro d’Italia cycle race passing close to the beer brewery in Biella, Northern Italy.
The result? This pedal- and Pi-powered beer dispenser that went on a 4-week celebratory tour ending in Glasgow.

A rather dandy Pi-assisted Draisine
For a minute in the 1800s, before the introduction of pedal power, the balance bike, or Draisine, was the fun new way of getting from A to B.

A team at Saarland University, Germany, headed by Prof. Holger Hermanns modernised the Draisine, bringing this old vehicle up to date with power assistance thanks to the Raspberry Pi.

Raspberry Pi–powered cycle helmet
Jen Fox’s Raspberry Pi safety helmet prototype uses an accelerometer and a Raspberry Pi Zero to monitor impact force, notifying the cyclist whether or not the impact of their fall deserves medical attention.
Check out my latest Hacker in Residence project for SparkFun Electronics: the Helmet Guardian! It’s a Pi Zero powered impact force monitor that turns on an LED if your head/body experiences a potentially dangerous impact. Install in your sports helmets, bicycle, or car to keep track of impact and inform you when it’s time to visit the doctor.
While you should always seek medical attention if you have a bike accident, the notification LED on the helmet is a great way of reminding stubborn cyclists that their accident was more than just a tumble.

Matt’s smart bike light
This one comes up in conversation A LOT at Pi Towers. Matt Richardson’s smart bike light project uses a Raspberry Pi and hall effect sensor to determine the speed you’re cycling at; a project displays your speed in front of the bike.
Here’s the first prototype of the Dynamic Bike Headlight. I managed to get it out onto the street to try it out, too! My previous video about it: http://www.youtube.com/watch?v=UzRAcZq0imM View other videos on the vlog: http://www.youtube.com/playlist?list=PLOPvnSRDf2EuIYj18l7iBdgt-27ZnOAdP&feature=view_all Subscribe here: http://www.youtube.com/subscription_center?add_user=mrichardson23 Visit my site: http://mattrichardson.com/
For those who know Matt Richardson, we hope you appreciated this blast-from-the-past, beardless Matt. In fact, we know you did.

The Bicrophonic Sonic Bike
British sound artist Kaffe Matthews has created a new type of cycling experience. The cyclist divides a virtual map into zones, and the Bicrophonic Sonic Bike plays back music to the rider based on which zone they are in, courtesy of an on-board Raspberry Pi with GPS dongle and speakers.
Bicrophonics is about the mobility of sound, experienced and shared within a moving space, free of headphones and free of the internet. Music made by the journey you take, played with the space that you move through. The Bicrophonic Research Institute (BRI) http://sonicbikes.net
As you can see from the video, the sound played can range from the calming peace of the countryside to the rather loud, disturbing buzz of the city.

Hacked Kindle bike computer
David Schneider’s bike computer displays speed, distance, time and more on a Kindle he hacked with the help of a Raspberry Pi.
A Raspberry Pi and Kindle make vital information about your bicycle journey readable. Read more: http://spectrum.ieee.org/video/geek-life/hands-on/video-build-a-better-bike-computer
The experimental browser on the Kindle displays a web page hosted on the Raspberry Pi. And the glare-free E Ink display makes the screen easy to view regardless of light conditions — perfect for sunny weekend bike rides.
