The lever is a selection between high and low gearing, so it's essentially a 2 speed bike. The ring gear on the front differential was free wheeling due to damage so I welded it in place. Thank goodness they made these out of steel rather than plastic haha!
I wanted to post mostly because I thought it was cool and I can't find any information on them so maybe this will help people pop up with this really neat Trike.
kids rode one today.
used to push each other as kids on it, got it second-hand in the 70's, pedals never worked, linkages gone, been welded on many times... we used it on our dirt driveways.
my girls just discovered drifting on my paved driveway-wow what a blast!
