  1. A friend of a neighbor just stopped by on his long ride down the Pacific Coast. He had a two-wheeled
    recumbent that was pulling-------no, make that being pushed by a trailer. The trailer had a 3-hp B &
    S gas rototiller engine. It was belt-driven and had a centrifugal slip-clutch, that was taken off an
    old motor scooter. Both trailer wheels turned on a common axle with no differential function. It had
    throttle and turn-off controls on the bike. He said it gave him no control problems and the way he
    handled it, I believe this is true. You'd think the pusher would cause trouble unless the throttle
    was controled very carefully during stops and turns. He had handlebar and tailbags and a big bag on
    the trailer. He said that ordinarily he does no peddling, unless he runs out of gas or ditches the
    trailer temporarily for some local riding on a stopover. Mileage has been about 140 MPG.
    Surprisingly, he said that so far, no cops have given him any heat. Too bad we don't take binaries
    here or I could show a picture.

  3. Cool. I have always liked the idea of a fast racing bent coupled to a trailer. Aside from the push,
    you could run a killer light set, having the engine a few feet further behind makes it even quieter.
    Also it would be good to make the trailer impact absorbing for safety.

  4. I might add that this motor had a super muffler that was about 2 feet long and eliminated all but a
    small noise. It looked much like the extractor mufflers that are used on VWs and dune buggies. By
    using a 4-cycle rototiller engine, that is designed to lug down to low rpms and still keep running,
    the use of it without gears was made more feasible. Also, the drivewheel for the belt was on the
    end, on a horizontal driveshaft, turning in the correct vertical plane to match that of the axle
    below. The engine was turned sideways on the trailer, so the drivewheel turned parallel to the
    direction of travel. A lawnmower engine would have a drivewheel mounted on its vertical driveshaft,
    turning horizontally, on the bottom. If you tried to run these engines turned on their sides, there
    would be problems with gasoline feed and the oil in the pan.

    Certainly, this trailer would serve to provide a greater visual presence and if a car rearended
    it, the rider might have a better chance of survival than if the bike was struck directly.

    See also MotoBob electric powerassist trailers.
    I've been told the concern with Motobob is not stops and turns as much as bumps and low friction surface wheelspin.

    I'd bet large that a negative effect on safety would be more likely.

    have done some work on a suspension MotoBOB It is like having an extra set of legs pushing you down
    the road. Pull the trailer off and you get your bike back. Nicely done Steve "Speedy" Delaire
