Spokes, the Lothian Cycle Campaign, has been at it since 1977. It has a membership (it’s free to join) of around 1000.
When it began, not many people cycled in Edinburgh. Its first campaign was for a cycle path through the Meadows. The council (then Edinburgh Corporation) was strikingly disinterested, even hostile. One councillor apparently said “over my dead body”.
Since then, constant campaigning to improve conditions for cyclist in Edinburgh. 3 Newsletters a year (available in bike shops and on-line), monthly Spokesworkers for activist members and countless, rallies, Bike Breakfasts and letters to council and Government departments.
