    Oh, check this 1920 Briggs-Stratton Cyclecar I spied in a friend's auto show guide today; anybody seen one o' these babies before? Anybody up for making a replica?

    Like you, I was intrigued when I discovered these cyclecars, so when I found a website (www.aosmith.com, I think) that had made available the original blueprints for the vehicle, I was determined to build a replica. I used the exact original dimensions, and used a bike motor to drive the 5th wheel. I did a lot of research and found that the original engine is the grandfather of all subsequent B&S small engines! If you google "Smith motorwheel" or "Briggs motorwheel" you will find a lot of information. I wrote two entries for Wikipedia on the motorwheel. I am attaching some photos of my replica.

    I'll tell you what, this settles the location of any "Autumn Leaves" Alabama MB.com meet, we're coming to Winston County and racing around on YOUR toys.

    The Natural Bridge to Looney's Tavern race !!

    Again, excellent detail !!

    Hey! That's my other project. I love those things- I have a rebuilt old Briggs engine (not that old) and the plans...and a pile of parts, but the retro-board track racer comes first.

    The Motorwheel used to show up at the Swap meets. I hadn't seen a cart with one till a few years ago, you don't see them any more. This is how thy mount on the bike. Have fun, Dave

    Ah nice, - I haven't seen a picture of a Smith Motorwheel fitted to a bike before. Thanks for posting the picture link :grin:

    It is cool to see one in motion. The bar going up to the seat is like a spring follower so that the wheel stays on the ground for turning, when you lean over it is compressed for a left turn and extends for a right turn. They are a beautiful thing to behold, but the last one I saw was expensive, I think 3,000. Have fun Dave

    PS: There was a cart made with a Maytag Washing Machine motor, it also fetches a pretty penny. Google (Maytag racer) at auction one sold for 13,000, it was a 1936 model. You could make a replica and use one of the Happy time motors.

    I love that cooling fan arrangement - can you say health and safety nightmare... I guess people were saner back then and wouldnt stick their hands in an engine bay with the motor running... I almost lost a finger that way once...

    That was the time I learned that the fan on 1960s engines spins with the engine. Luckily I just lost some skin...

    I agree, I think folk were just more plain sensible in those heroic days of motoring and kept their fingers away from moving parts. My one accident with a cooling fan was not intentional, my hand slipped while I was adjusting the idle speed on an aged Austin I owned at the time and I received a very smart wack on the back of my hand. No broken skin, but the bruise went all kinds of interesting colours before it faded away.
