I've taken on the task of getting all the cycle forums into the Love Your Bike Cycling Events Calendar and there is quite a contrast between the different councils.
Manchester Cycle Forum runs every quarter, is chaired by a city councillor and usually packs out the room it is held in. Details of the meetings are posted on the council web site, but agendas and minutes of the meetings are not posted on the web site.
Salford Cycle Forum is also held quarterly, run by the cycling officer. Details of the meeting are available on the council web site along with agendas and "Action Sheets".
Trafford Cycle Forum is held quarterly. It is chaired by a cycle campaigner rather than an officer or councillor. Agendas and Minutes are both posted on the web site and the meetings are well attended.
Oldham Cycling Forum has restarted this past year and is an ad hoc affair. There is no information on the web site and meetings have come to my attention via twitter, so I have publicised them as best I can. Some details have also been posted on the TfGM web site.
Stockport Council’s Public Cycle User Group "meets once per month in the Town Hall, and is open to all cyclists and others who have an interest in cycling." There is a web page with the most recent draft minutes. In fact the general meetings are every other month with specialised meetings in the other months. Attendance is a bit smaller.
Bolton "At long last, the Bolton Cycle Forum is back! The next meeting will be on Wednesday, 12th November 2014, starting at 6pm." First meeting will be at the The Bolton Artillery Suite, Bolton Town Hall, Victoria Square, Bolton, BL1 1SA. So far this information hasn't reached the council's cycling web page I could find.
Bury Cycling Forum "was established in 1996 at the request of local cyclists. Until 2011 it met four times a year to discuss cycling issues and was attended by cyclists, Council officers and occasionally, Council Members. The Council doesn't currently have a cycling officer so meetings of the forum are not being convened." So this is a dead cycle forum.
Tameside is another dead cycle forum, it folded over four years ago.
Rochdale has no sign of a cycle forum, and very little info on their web pages.
Wigan also has no sign of any consultation on cycling, there are just the usual platitudes on cycling on their web site.
