comment How do I wrap a road bike handlebar?
Use hockey tape. Standard bar tape works so poorly I've never figured out why anyone uses it.

comment Why is a steady cadence so important? Or is it?
(That said, a 6.5 mile ride is not any sort of "challenge" to anyone who's in halfway decent shape. You're welcome to ride that distance using any style that suits you.)

comment Why is a steady cadence so important? Or is it?
Certainly every rider (moreso as you get older) needs occasional "breaks", but these should involve getting off the bike, walking around a bit, having something to drink and maybe eat, and taking a pee. Simply coasting for the 30 seconds you might get away with it on flat ground with no tailwind is not a "break".

comment front wheel takes more impact than rear?
That's known as a "snake bite", often the result of running tire pressure too low. But definitely the front wheel takes more abuse than the rear.

Human muscle efficiency is less if you pedal intermittently vs pedaling continuously at a reasonably constant pace. And, given that wind resistance is proportional to the square of relative velocity, riding fast then slow is less efficient in that regard as well.

comment Why don't we see this special progressive 3x5 gear setup being offered?
It is relatively easy for a professional biker to get any (physically possible) gear arrangement that he wants. If they aren't being made, they aren't useful. In fact, you could likely make your proposed setup yourself, aside from the problem of finding derailers capable of handling the ranges. It's easy enough to remove cogs from the rear and replace them with spacers. And a guy with an NC machine could craft your front sprockets, if you can't find them on the market. Have at it!!

comment Gear cables replacement - inline barrel adjusters
I prefer to have them near the top of the down tube, if geometries permit. But many modern bikes have "haywire" cable patterns and they have to go where they fit.

comment how to increace the friction between tyre and road
You have made the question even more nonsensical. Tire traction (within normal bounds) has virtually nothing to do with bike efficiency & necessary power.

comment Worries about a gear ratio of 1:1?
There is a slight theoretical issue, in terms of the repeated stress on the same point of the wheel. (Would also be present, to a degree, for 2:1, 3:2, etc ratios.) A bike that is designed to take mountain riding, however, should have wheels built to a level that it would not be a big concern, especially if only used intermittently.

comment Sensible shifting on a triple chainring?
The 3x7 arrangement gives you more options, especially when you must shift quickly. On a reasonably modern bike all 21 speeds are usable, even if one does tend to "prefer" combos such as you describe. And, on my bike, I will often, to slightly adjust gear ratio, shift up on the ring and down on the cluster or vice-versa, to reach ratios that are not available by just shifting the rear. But the 1x11 does have the advantage of simplicity, if that's your goal.

comment How do I remove the front axle from a sealed bearing hub?
Some early sealed bearings had an axle with no sort of inner cone, and the axles would slide out, leaving the bearings in place. But apparently that's not what you have.

comment Has anyone tried this “poor mans” homemade electric bike idea?
Getting a slower motor (of the same power) will do nothing different from what simply changing your external gear ratio would do.

comment Has anyone tried this “poor mans” homemade electric bike idea?
Unlikely to be sufficient, but maybe will work for testing.

comment Has anyone tried this “poor mans” homemade electric bike idea?
I'm a little skeptical as to whether the wiper motor is up to the challenge, but it sounds like a fun thing to try, if you have the time and resources. Don't forget that you will need some sort of speed controller.

comment how to design a shaft and gears for shaft driven bicycle
Without suspension the main decision is with regard to the right-angle shaft connections at crank and rear hub. These need to be non-bulky (not adding too much to the width of the crank shaft and rear axle), they need to provide the right gear ratio, and they need to be able to withstand considerable torque.
