Shriners parade bike? (original pocketbike)
From a great mini bike site:
Open up some of the old minibike links and see where some of us got our start in bikes............yes, lawn mower engined minibikes from the 60's and 70's.
Now look at this (supposed) original Shriners bike, used in parades, fundraisers etc. This thing is tiny and very unique. probably worth $$$$
One more engine photo, plus notice the single sided swing arm and front fork assembly in the above photo's......way ahead of it's time. (ha)
