comment QUIET Exercise Bike Under $300?
(I'm trying to remember what bike are at my gym. There are a half-dozen different brands, most of which do pretty well in a fairly challenging environment.) (But most would be over $300.)

That Sunny unit appears to be an old-fashioned friction unit, not magnetic resistance.

One thing you should do is get a rubber mat to put the bike on. You want a heavy-duty one about a half-inch thick, such as is used in weight rooms. And it wouldn't hurt to put a piece of plywood under that (though not directly on another hard surface) so as to spread out the vibration a bit.

In many ways a crosswind is the worst.

Part of the problem is that a cyclist's performance is generally optimized when he's right "on the edge" between fully aerobic muscle action and at least partially anaerobic action. When you go over a certain point in effort the muscles begin burning fuel without oxygen (which is less efficient) and, more importantly, begin burning glycogen stored in the muscles rather than sugar from the bloodstream. This depletes your body's limited store of glycogen and also produces large amounts of ketones that can build up to toxic levels (resulting in "bonk").

When you slow down on a hill there are two problems: 1) if your speed drops below about 5mph you have trouble remaining upright, and begin expending more energy balancing the bike. 2) Muscles expend energy based on force x time, not kinetic energy delivered. If you are, say, riding a trike and slow to zero mph on a hill you're still burning energy, just to maintain that fixed position.

It's also important to consider whether you're riding a relatively short fixed distance, something you can complete in maybe a couple of hours, or doing a day-long tour, where "saving some for later" is important.

Yep, theory can give you some clues, but eventually it boils down to individual strengths and weaknesses.

Before you even worry, ride on it for a week and re-true it.

comment Different Gear Type when there's no Front Derailleur?
Yep, 300 miles is no big deal. Somewhere between 2000 and 5000 miles is where wear would begin to be a problem. But the rear derailer should be cleaned and checked to be sure it's not bent, and the "freehub" should be checked to be sure it's not binding.

comment Convert Recumbent to Handcycle?
I'm sure it's been done, by homebuilders. You might see if you can find a homebuilt bike site for more info.
