Motorvation Sidecar History

What was to be Motorvation Engineering (Sidecars) Began in 1971.

Ed Millray began working on the first Royale Sidecar prototype in 1971 at his home in Colton, California. The first few sidecars were made of plywood. One was a two person sidecar and the other a single person sidecar. Pictured below is the two person Royale Sidecar made of plywood.

Work then began on making a plug and a fiberglass mold to build production sidecar bodies. Below is Ed Millray and his two children working on making the sidecar plug.

After the plywood form was made it was covered with mahogany skins, then covered with plaster and sanded smooth and covered with coats of fiberglass resin and sanded. As in picture # 11.

Ed & Joy Millray sold their sidecar company around 1976 to Tom Peterson and I believe this is where the company got the name of Motorvation Engineering. Tom Peterson purchased the Spyder T-1 Sidecar mold from the Simon Sidecar company, owned by Jerry Simon as he designed and built the Spyder Sidecar.

Cool fender design. Used the same Lucas taillight that the SOA Eagle Sidecar used.

The Jerry Simon Spyder Sidecar had the internal frame from the beginning as can be see by looking at the mounts in the above picture.

-----------------------------------------------------------------------------------------------------------------------------

In August 1979 Jim Sontag purchased the Motorvation Engineering Sidecar company from Tom Peterson. Jim lived in Los Angles California and was in the music business. Managed bands and promoted live music in his club he owned with a partner. The music business was slowing down and in 1979 Jim Sontag paid approximately $50,000 for the Motorvation Engineering sidecar company and moved it to Reseda, California. Jim had always been interested in Hot Rods and motorcycles so building sidecars fit in with his interests.

Durring the recession of the early 1980's Sidecar sales were very slow and Motorvation Engineering filed for bankruptcy protection. Jim then moved his sidecar company to a smaller shop in Montrose, California.

In 1980 Motorvation Engineering introduced the Roadster Royale convertible version of the sidecar. And in 1981 the Formula II Sidecar model was introduced. It would be the largest double wide sidecar they would produce. Pictured below.

Motorvation Engineering Formula II Sidecar

Motorvation Engineering Formula II with flip nose option

 The Formula II had the flip nose option to make it easier to get in and out of. The seat would fold down or could be remove if a person wanted to lay down and sleep in the sidecar for camping.

 In 1993 Jim Sontag moved Motorvation Engineering to Sibley, Iowa into a very large building that was formally a Car Dealership and later a strip mall. Many states were offing economic incentives to move to their small towns that were in economic bad times. This worked out well as Jim and his wife Mary grew up in nearby Minnesota and they wanted to be close to their relatives after having moved to California in the 1960's.

 Later on Motorvation Engineering would introduce motorcycle cargo trailers and offer motorcycle trailer hitches for many motorcycles.

-----------------------------------------------------------------------------------------------------------------------------

 Motorvation Engineering would build 3 sidecar models at the Sibley Iowa factory.

The Roadster Royale Double Wide Sidecar.

The Roadster Royale shared the same frame and suspension as the Formula II. The Roadster was a little shorter than the Formula and had a safety glass  windshield built in, instead of a bolt on Lexan windshield as on the Formula II. Both the Roadster Royale and the Formula II sidecar bodies were made from hand laid, marine quality fiberglass for durability and safety. The Roadster Royale offered fender and wheel options like the Spyder sidecar did. Many options were available like, electric lean motor, sidecar wheel brake and convertible top.

The Formula II Double Wide sidecar.

The Formula II sidecar is a two passenger sidecar. It was the first sidecar to have an independent sidecar brake and a lean control motor so the suspension can be easily adjusted so it will not pull left or right going down the road. Sidecar had a well built external square tube ladder frame platform with a trailing swing arm and adjustable torsion bar suspension. Trunk had almost 5 cubic feet of storage behind the seat and could be ordered with a  chrome luggage rack to carry even more stuff. The optional front hatch/lid  "Flip Nose" option made the Formula II the easiest sidecar to get into and out of that Motorvation made.

Spyder single person sidecar for smaller motorcycles.

The Spyder Sidecar was constructed with a fiberglass and steel plate laminate monocoque chassis. There was no external frame giving the sidecar a very clean look. The base weight of the Spyder was 190 pounds making the best Motorvation sidecar model for motorcycles as small as 500cc. The over all body length was 75" with 52" of leg room. The overall width of the Spyder was 35" including the fender and wheel. The cockpit opening was approximately 25" by 20". All the Spyder Sidecars came with a fully finished, upholstered interior and a contoured seat. The rear locking trunk had approximately 3.5 cu. ft of storage and could be fitted with the optional fuel tank.

The Spyder suspension was a trailing swing arm with a Progressive Suspension Magnumatic adjustable air/spring shock.

     Wheel and fender options were many. The standard on the Spyder T-1 were a chrome wire spoke wheel with a bolt on the body fender. The Spyder H-D comes with a Harley-Davidson style fender. Custom wheel options included factory Harley-Davidson mags and after market wheels. Fender options for the Spyder include a FLH, FX, Bob Tail and Duck Tail Harley-Davidson style fenders with five different tail light choices too. BMW owners could order the Stibe style fender option. 

   Other options were a small Brooklands Windshield or full size wrap around windshield, wheel brake and luggage rack.

Motorvation Engineering had their own paint department to color match a sidecar to the customers motorcycle. Motorvation made  many of the sidecar and trailer parts at their factory using a complete machine shop, welding shop and upholstery department and made the shipping crates too. They outsourced the fiberglass body manufacturing, chrome plating of mounts, etc.
Jim Sontag operated the sidecar company in Iowa till he died in a Train collision on a very snowy day on his way home from the factory. Jim Sontag R.I.P Janurday-11-1997. 
His wife Mary Sontag took over running Motorvation Engineering after the passing of Jim Sontag. Mary was working in a nursing home as an activities director at the time. Later on she had help from her son Chris in running the factory.
Motorvation Engineering filed for Bankruptcy for a second time in 2020 and it was a Chapter 7 Bankruptcy this time so the sidecar company was liquidated and is out of business, unfortunately!
Mary Sontag died March-11-2021 while staying with her daughter in California.

Below are the drawings for the sidecar mounts Motorvation Engineering used. They are a different style and size than other American made sidecar companies use. Meaning the lower slip tube mounts are 1-1/4" O.D., smaller than the 1-1/2" tubes other sidecar companies use and all 4 mounts use a clevis end as a connection to the motorcycle eye nut.

You can see the 4 U-clamp motorcycle mounts attached onto the ends of the sidecar mounts. This Spyder had its own separate brake system. The silver bar in the middle is a brake pedal. It is connected to the master cylinder right next to the rear strut.

Motorvation Engineering was able to do alot with their distinctive U-clamp motorcycle frame mounts. Here are some examples of their mounts on different motorcycle models.

Here is a simple way to make a sidecar mount with a square tube 1-1/8" with a .120 wall. Weld a 3/4"-16 tpi threaded insert into the end of tube and attach it to motorcycle frame with u-bolts. Pictured above is a Harley-Davidson Shovelhead upper front mount bolted to both down tubes.

This is the rear sidecar mount. Harley-Davidson Sidecars just uses one rear mount. Motorvation Engineering made a bracket that attaches to the passenger floorboard bracket and installed an eye nut mount in the bracket. A very clean and clever way to attach the mount.
