comment 2 questions: What bike is this? Also is this front wheel too big?
Age-identifying features: Lugged frame, cotterless crank, stem shifters. The brakes are a distinctive style that could be easily identified by someone into that sort of stuff. The rear derailer appears quite short -- almost certainly only a 5-speed rear (though of course this can be checked).

comment 2 questions: What bike is this? Also is this front wheel too big?
I would guess it's a bike from the early 80s. If so it's designed for 27" wheels and tires. 700C wheels and tires would be a hair on the small side.

comment Will slightly loose bearings result in damage?
This depends on several factors, mainly the nature of the axle. A solid axle does not get any tighter as nuts are tightened. A quick-release axle, on the other hand, is compressed slightly when the skewer is tightened.

comment How should the brakes on a child's bike be adjusted?
Also keep in mind that with a new or recently "recycled" bike the brake blocks are apt to wear rapidly at first (and cables are apt to stretch a fair amount), so the tension should be a little tighter than minimum requirements.

comment How should the brakes on a child's bike be adjusted?
More important than the braking power (so long as it's in a reasonable range) is the grip range of the brake levers. The cable tension should be adjusted so that a child's hand can grasp the lever and begin squeezing before the lever gets stiff, but not so loose that the lever can bottom out in a child's grasp.

comment How to fix precession in pedal axle?
If you have a single-piece "Z-shaped pedal assembly" then that's a one-piece crank, common less expensive bikes. It is fairly common for the bearings to work loose in these. The "cups" that retain the bearings likely need to be tightened. (But note that often they get so loose that the ball bearings fall out, meaning it must be disassembled and the missing pieces replaced.) However, the image you link to shows a 3-piece crank, which only rarely exhibits this problem.

comment Do skilled cyclists really “use the front brake alone probably 95% of the time”?
If you lock the front wheel (on dry pavement) you don't skid, you go head-over.

Note that, unless traction is compromised somehow, there is no such thing as a front wheel skid -- weight shifts to the front, traction increases, skidding is impossible ... but going head-over is quite easily accomplished.

I know a guy who went head-over in an off-road race. He's been in a wheelchair ever since.

comment 26er Rims for a 26x1.95 tire?
All 26" rims designed for tires with a decimal width designation (vs a fraction such as 1-7/8) are the same diameter. Within reason they will accept wider or narrower tires that also have a decimal width designation. (Ie, the "ISO" number on such a tire should be "XX/599", where XX is the tire width in millimeters.)

comment Converting from 7-speed to 10-speed rear wheel
Yes, you need to clarify. Are you talking about changing the sprocket cluster ("cassette") on the wheel? If so, what change precisely are you proposing?

comment How do I know what is wrong with my brakes?
@GordonCopestake - If the levers are bottoming out it likely would take at least two turns on the barrels to fix, and it may be time to tighten the cable where it's clamped by the brake.

comment How to commute to work on your bike and dress up
If you study it a bit you can learn how to pack your clothes such that they don't get exceptionally wrinkled in a pannier.

comment How to fix precession in pedal axle?
It should be noted that some pedals are quite loose on the spindles when they come from the factory. If the pedals are the all-plastic ones then this is probably "normal".

comment how do I fix my chain in this situation?
If you mean that when you pedal the bike, the chain moves, but no force is transmitted to the wheel, then most likely the "freehub" has failed. This would be something that a bike shop would need to fix. But note that there's a slight chance that your chain has simply fallen off the rear sprockets.

comment Always cycling in highest gear, why?
The gear is not your "cadence". "Cadence" is how rapidly (how many revolutions per minute) you turn the pedals. But cadence is related to gearing: for a given speed, the higher your cadence the lower (easier) the gear you'd use.

comment Front brake cable loose from barrel adjuster
The problem is that the cable is loose. If it were tight it would draw the ferrule into the barrel adjuster with little difficulty. Did the cable come loose somewhere else on the bike?
