I'd be willing to pay a small subscription fee for some kind of newsletter, club membership
Rather than a full glossy monthly magazine I think it would be far better to have a bi-annually or even quarterly magazine. Would be easier to fill up with features, could even get re-prints from iconic bikes magazine features of the past once you get round copyright. Would be cool to see bike reviews but even cooler to see some of the old adverts!!!
We do not even have to go down the hard copy route, magazines can be published on-line the software is out there!
We could try to get LBS, National Bike Stores, International Manufacturers on side by implementing a Retrobike Membership discount scheme similar to many Car Owner clubs. I'm sure that companies like BETD would jump at the chance to advertise directly to it's main customer group.
Tech support section and Parts Sourcing directory would be cool. Meet the Members could also be an idea, just think of it guys some of us could become International Superstars
I'm sure if such a magazine did get off the ground it would have an International following. Retrobike in my opinion is the best online Retro site, far better than the competition.
Just an idea
