klunk!

Finally riding a big boys bike
1960s Schwinn King Size Heavy Duti, built up with a NOS Whizzer Kit. I bought this probably 20-25 years ago from Cecil's Cyclery in Sedalia, MO. Mr. Cecil was a Schwinn Dealer since the mid 1930s. This was on his showroom floor. The Whizzer Kit was NOS when he installed it on a NOS Schwinn King Size Heavy Duti. The Whizzer Kit pre-dates the Heavy Duti, but still a cool set up. He had the crank arm bent to clear the motor, The rear fender was also cut to clear the belt. I do believe he ran gas thru it, and may have test ridden it. I have never attempted to fire it up. This is just as I found it. I do not believe the wiring to headlight and taillight are hooked up. There is some surface rust inside the tank. Other than that, there are some minor bumps from years of storage. I have not cleaned it up other than wiping the dust off. I currently do not know where the pedals are...I'll look for them. Pretty unique bike. Definitely one of a kind. Pick up in Columbia, MO, less than a mile off of I-70. It was brought to my attention that this is the harder to find King Size Heavy Duti with a 20" seat tube.

@sworley do you have this KS on the list? Really killer Whizzer.

It needs a much longer rear axle. It’s not even showing in the nut! It would be dangerous to ride in this configuration.
 
Not familiar with a wizzer but looks are deceiving. It looks like the nut is more like a rod coupling or bushing so the drop so the drop stand can rotate on it.

Exactly correct. The picture is very misleading, it's a special "shoulder nut" made specially to allow the Whizzer rear "drop down" stand to mount on the rear axle. I fully agree that nuts need to be on a bolt/axle where the threads extend past the nut by a distance equal to the diameter of the bolt/axle. However, this is a "special application" exception.

That nut could be hanging by 1/2 a thread !
Would be a heck of a wreck.
I’d have to take it apart, but, I’d bet underneath the drop stand there is a nut with an extension that acts as a pivot for the drop stand, and a surface for the outside nut to tighten down on, allowing the drop stand to move.

I’m not crazy about how the “drive” is supplied to the rear wheel, through the middle of the spokes, as it changes how the spokes are stressed, and how the wheel stays true, but, maybe they were low enough on torque that it isn’t an issue.

My Whizzer is a 1200cc Yamaha.

Ted, A Whizzer motor has all of 2 1/2 horsepower, the newer versions had a whopping 3 horsepower. The torque was so low they only needed a V-Belt to transfer the drive power, not a chain. That drive pulley is connected to "18", 105 gauge heavy duty spokes. The middle of the spoke is the strongest point of the spoke. Bicycle and motorcycle spokes always seem to break at the heads, never the middle. It's been a proven system for the past 75 years.

My last Whizzer was a Kawasaki Concours 14. Bikes are fun, "all kinds, and sizes of bikes".
