What Is Your Craziest/Wildest Motorized Engine Idea?

[5-7HEAVEN]

Now that my wild GP460 engine/friction drive bike is almost done, I'm looking for another crazy high-powered bike project.

Any thoughts you'd like to share?

well.............with Zomby, Graucho, Houghmade, Easyrider and others of exceptional design abilities all we need is the engine and a style to persue.

i still really want to get a LWB recumbent with belt drive going as my commuter.

PS, i though you felt you'd need a second 460 on the "iron dragon"

Hi 5-7
Yes funny you should mention it. We have a honda 350 motorcycle from the 70's.
My brother (ex member LuccianoPezziano) had it up to 85mph. It still runs like
a top and I have since inherited it. I had my brother in law (ex member terrence) do a quick
photoshop job to give me an idea how it may fit into a bike. Id have to fabricate a 11.5"
functional crank, but I don't think I would be doing to much pedaling.

I think I would set the engine on the "bench" and then build the bike around it. Chopped out of
course, with DOT tires. I truly think I could set a new standard. "The 100 mph club"

I have a 20" mongoose chopped up in pieces on the bench im stretching to 7 ft that I have
to finish. Then a schwinn OCC getting stretched to 7.5 ft after that. The 350 bicycle would be
a good winter project?

If I built every bike I dreamt of Id have hundreds of bikes though. :

Wow Graucho, that is truly insane!

Any more, guys?

I have in mind a full suspension tadpole trike with the 45hp Wankel and 2-speed tranny (with reverse) that I have sitting on the workbench. Some day.

I still like the pulse jet engine!! TJ

Pocketbike Engine On Friction Drive!

I have a modified pocketbike engine I bought on ebay a year ago. The owner sent documents that it dynoed at 10hp. This remains to be seen and tested.

I will probably remove the twin Mitsubishi engines on "The Dragon Lady". Then I'll install this pb engine on rear friction drive with 1.25" roller.

I have this insane notion that keeps bugging me. Most bikes tou see nowadays have rim brakes, right?

Why not a rim drive? What I envision is a wheel rim with machined in radial grooves that in effect turn each side of it into a REALLY tall gear, and a pair of smaller spur gears (one to each side) that fit into those gear teeth snugly. Drive their shafts in counter-rotating directions, and the wheel rim between them rotates. Reserve your hub for spokes and disc (preferably) brake.

I realize there are issues with this idea, but I wonder if it could be made workable?

Alternatively, think about a vertical shaft engine rack mounted driving a wheel with a bevel gear system, an opposite side idler wheel to hold the rim firmly engaged (and possibly to serve as the actual brake pad as well).

not good if your rim warps like they usually do over time.

I believe a member named Retromachinist is running a lawnmower-type vertical-shaft engine on his bike. It runs off the sidewalls using a socket as a friction roller(as in socket wrench).
