Is there a particular time of year when bicycle manufacturers,engine dealers, walmart, etc. run clearance to move last years merchandise.I am restoring a 1974 schwinn speedster but have decided not to motorize this one.
craigslist, e-bay...during the fall/ winter months.
people like to get rid of stuff cheap to get it out of their hair. the interest kind of dies off in the states that have cold winters and snow.
I have found MANY parts CHEAP on craigslist and e-bay between ocober and feb.
Gas Bike had a sale last winter that was pretty good. I got a Grubee angle plug 66cc engine for $99. I'd say get on several companies' email list. That way they can tell you when they're having a sale.
