Trail Horse E Z Rider. The exhaust goes to the rear. It rests on the bar and clamps to it. The exhaust then turns up at the same angle as the sissy bar. There is a pic of mine in the media section. Can't remember the model numbers, but they made 3 versions: rigid fork, internal spring...
Wheels, tires and front suspension are Cushman, frame is not. There were a couple of manufacturers who bought Cushman parts and used them on their bikes. Since Cushman parts were plentiful and readily available they were popular for modifications by individual owners.
Actually, I think it's a Sensation. I have a Manufacturers Statement of Origin for one. Don't know for certain, but Fimco bikes may have been re-badged Sensations. Fimco is still in business. They make sprayers.
The Skat Kitty elbow is machined from a street ell. An off the shelf elbow will probably not be satisfactory. Originals are impossible to find. A zinc-plated, machined repro with special nut is available.
Wheelbase = 36"
frame height = 15.25"
Handlebar width = 21.5" from end of bar to end of bar.
Most parts are available as reproduction. I get parts from Jim's Scooter Parts in St Paul. He is the only full stocking dealer.
A friend recently made a couple Skat Kitty parts. Parts are located in Seville, Ohio.
Kickstand, zinc plated, $25 plus shipping.
Exhaust elbow and nut, chrome plated, $60 plus shipping.
High quality repro parts.
They are 12" Hawk wheels. Used on their Pony Cycle scooters, their Wards scooters, Simplex Compact Seniors, and some trail scooters. Prone to having the brake backing plates cracked. Looks like original blue paint from a Pony Cycle.
