I did a little searching and could find very little on CCM bikes here and perhaps this is because they are your ubiquitous Canadian bike and not well known in the south.
When I was a kid most folks rode CCM bikes and I would dearly love to find a Mustang which was my first real bike.
I presently have 2 vintage CCM bikes...
The first is a 1933 Coaster bike I found parked in the weeds at our shop and I was thrilled to find that all it's bits were intact and that it is in excellent mechanical shape with solid and true wheels. I'll be finsihing the restoration over the winter which will entail a repaint of the bike, re-spoking and painting the wheels and re-chroming of the stem and bars.
It's a fabulous bike to ride.
A also found a 1940 double bar frame and decided to build a retro club bike...the wheelset came off of a 1964 CCM and I'll update this pic as soon as I bring the bike back from the shop. It just got some new swoopier moustache like bars that are taped and a new fork (that white ishiwata was broken ) after a little mishap with a car.
