From Physorg.com:

‘Bicycle manufacturers have never been able to say precisely how a bicycle works’, explains Dr Arend Schwab of the Faculty of Mechanical, Maritime and Materials Engineering (3mE). ‘They have always had to refine their designs purely through experimentation. In our model, they can enter into the computer all of the various factors that influence the stability and handling of their bicycle. The model then calculates how the bicycle will react at specific speeds.’ The model has recently been published in the science magazine Proceedings of the Royal Society, Series A.

Because the model has the ability to indicate whether a design will deliver a jittery bicycle, or indeed a stable one for seniors, the bicycle industry is highly interested in the findings.

Milwaukee bicyclist shoots motorist after near collision

A bicyclist shot a motorist after the man’s car nearly hit the bike on Friday night, police said.

The 28-year-old driver of the car stopped to check on the bicyclist, who had fallen to the pavement around 10:45 p.m., police said.

The bicyclist got up, fired three shots and hit the driver once in the shoulder, police said.

The motorist drove to the house of a friend, who then took him to a hospital. He was treated and released.

Police said they were looking for the bicyclist on Saturday. No other details were released.

This real-life Spike Bike was mentioned in the Milwaukee Star Tribune. Reported also at WKBT and FOX 6.
