Yes, I assumed conventional gears, my bad for not considering your magical frictionless fairy gears. My only excuse is I'm stuck in the real world.

You have it backwards as usual, horsepower is the product of torque times speed over constant. The 30 cylinder engine was designed to produce the torque they needed at the speed they wanted. Yes the hp rating could be increased by increasing the RPMs, but that would be stupid. All that would be accomplished is more wear on the engine and the need to gear it back down to a usable speed. They already had the torque they needed and Torque Does the Work.

Your 2 liter 4 won't get far in a tank or a semi.

The basic bicycle is a pretty simple design, but it took a long time and lots of dead ends to get there. I have a feeling clothing had a lot to do with it.

Innovations were necessary because the human output too much torque. That large front wheel converted high torque - low speed into low torque high speed. With gears and chains, then smaller wheels could accomplish the same conversion. And provide the many different torque - speed ratios that a bike needs for changing terrains.

But again, it all about that simple concept taught in school science - the product of torque and speed. So that a much less than 1 horsepower engine (the human) could adapt to changing loads.

It was designed with sufficient horsepower so that gears could select a torque necessary to maintain a speed. Horsepower (not torque) is always the relevant parameter.

As usual, due to too much emotion and insufficient knowledge, you again got it wrong.

4 cylinder engine can produce that same torque. But insufficient speed - due to insufficient horsepower. You also got that wrong.

Anyone not educated by hearsay (who can do simple multiplication) would know that. Only motors with sufficient horsepower can produce a torque at required speeds. Somehow that multiplication is just too hard - the routine expression from another lesser educated man called George Jr.

Meanwhile, that engine apparently had a very short life span due to its low performance numbers.

Ass backward as usual, the engine is designed for torque, they sure as hell don't add a bunch of extra pistons to make more rpm. Gear selection dictates the speed the work gets done, torque does the work.

So, I was rolling along rattlesnake trail a really sweet single track with a lot of turns climbs and descents when suddenly I see ...
