We have two questions today, that have me questioning whether we as a community should even be attempting to answer them.
One is a user attempting to resolve a problem with a fixie with no brakes - which is illegal in most parts of the world, and certainly a danger to themselves and to others around them. fixed gear bicycle chain tension
And another is looking for some sort of super loud bike based speaker system that is going to be a nuisance for all other road users around them, and probably lessen their own awareness of their surroundings. Soundsystem for bicycle
I feel that ethically we shouldn't be enabling this type of anti social behaviour, which will not only be potentially putting people in danger, but also possibly negatively impacting the public's perception of cyclists in general.
