Old, tired, crazy.

comment Axle to wheel bore ratio?
Yeah, you want the fit to be as close as possible without being tight. Sometimes you can use a bushing of copper pipe, sometimes you can find a suitable bushing in a hardware store.

comment What is neuromuscular endurance in the world of bicycling?
"Neuromuscular" simply denotes that part of human physiology that has to with how the motor neurons interact with the voluntary muscles. To the extent that cadence is controlled by the nerves, it has to do with cadence, but it has to do with many other things as well. Much of "muscle fatigue", et al, has as much to do with the nerves as with the muscles.

comment Stationary bike calories
Simple. Just construct an insulated room around the bike and measure the rate of temperature rise.

comment my chain is skipping on my single speed
From that angle the cog appears to be worn out, but a side view would be more convincing.

comment Where should I sell old bike parts?
I would try Craig's List. If you want to give some away, look for a local organization that rebuilds old bikes for charity.

comment can anyone convert RPM into km/h?
Most likely the RPM figure is for the motor, not the driving wheel. You need to figure out what the gear ratio is to calculate the RPM of the driving wheel, then multiply times diameter to get distance per minute.

comment How do I know what is the right bottom bracket for my old road bike?
Basically your "standard" square-shaft bottom bracket cartridges come in symmetrical and asymmetrical versions. The symmetrical version is OK for a double front, but you need the asymmetrical ("offset") version for a triple. The offset (when present) is typically 3-5mm. Unfortunately, the offset is hard to measure on your standard Shimano cartridge because the cartridge itself is built asymmetrically, due to having one integral cup.

comment First time commuter needs advice
In my view, one can never have too many lights. I would disagree. With ten lights you'll always have several that are not working, and you will spend more time keeping the lights working than you do riding the bike. I'd say have a main and backup for both front and rear. The main front should be a good rechargeable unit, the rest can be disposable batteries. The backup rear is one of those flashing LED reflectors running off of a AAA penlight cell. Or get a generator front hub.

comment Can I use a mountain bike to go bike touring?
And you certainly don't need a custom frame for touring. I would guess that maybe 5% of transcontinental tourists ride on a custom frame.

comment Can I use a mountain bike to go bike touring?
The main thing is that you probably do not want suspension for road touring. Beyond that, the posture needs to be comfortable for hours at a time. And you need to consider how your posture affects wind resistance.

comment I have a 2013 Diamondback Podium 3. Is it possible to use it as a touring bike?
Unsuitable, I'm afraid, for anything other than lightweight "supported" touring. Due to the AL frame you risk damage if you put substantial weight on a clamp-on rack. I recommend looking at the REI Randonee -- a relatively moderately priced tourer but decent quality and can handle anything.

@Kibbee - But added mounts don't look "lean and mean", and appearance is probably a big reason why he bought that bike in the first place.

Of course, your "two things" conflict. Lots of people don't "just do it" because they were warned to get a Dr's OK first and they never get around to seeing the doctor. Unless you know you have health problems it's likely healthier to "just do it" without the checkup first. You won't feel as guilty when you eventually do see the doc.

comment The make and year of my bike
That's not nearly enough to go on, unless you get really lucky. Pictures would help. And why do you want to know this info -- do you need exact info or will "educated guesses" do?

comment What type chain lube should you use in a sand and salt water enviroment?
It should be noted that most new chains are delivered with wax lube coating.

comment How does weight and strength of a person effects the riding of bicycle at higher speeds?
The main force being overcome when cycling on level ground is wind resistance. A larger body slightly increase wind resistance. Adding weight (without added muscle) serves on useful purpose -- it increases wind resistance and rolling resistance. Adding strength/power is the only way to increase speed. If you are standing all the time at max power then in theory adding weight will increase power, but probably not in proportion. But, eg. using a lower gear and pedaling faster might increase power even without added weight.

I would be a little worried that sand would get in the belt and jam it.

Good point about soreness. There will be generalized soreness the first few rides, and you need to give yourself a chance to recover, but not be totally motionless while doing so. And one needs to beware of more severe "focal" pain, especially if taking statins -- a pain that takes 18-24 hours to appear and is localized vs general muscle stiffness may be the beginnings of rhabdomyolysis and result in substantial permanent injury if you try to "work through it". Remember, pain is nature's way of saying "Don't do that!"

Remember, if need be you can walk the last 3/4 mile -- there is no shame in doing so. And definitely don't try to do it every day for starters -- maybe twice a week for a month or two, then increase frequency as you feel up to it.

(Probably your best bet is a semi-dry lube, then be fairly aggressive about cleaning & relubing the chains.)
