comment What is my bottom bracket spindle length?
Even with both cranks off and the axle removed it's hard to measure, since there's really no defined point to measure from. You don't measure tip-to-tip, and the two ends are often asymmetric, not tapering down to the same point. I've never seen a description of how to measure accurately.

comment Is cycling with crystal sunglasses dangerous?
I don't know about non-prescription stuff, but all prescription eyewear sold in the US must employ some form of "safety glass" to minimize risk of injury.

comment Identify missing fender part
It's been about 30 years since I last saw a leather washer. If a washer is needed, rubber or plastic will work fine, and plain old steel in a pinch.

comment Replacing Shimano RS21 rims
Likely it will be just as economical to buy a new wheel.

comment Increasing stamina while in the office
Note that the higher the cadence the more important it is to get your seat height right.

You can always get a standing desk and put a treadmill under it.

comment Punctures on outer part on inner tube at valve on both front and rear tyres after 75miles . Signs of abrasion at puncture site.
Most likely the valve stem was being pushed against the tube due to a combo of (slightly) low tire pressure and not having the stem all the way through the rim hole. It's also possible that the tube got "bunched up" near the stem while installing. (Before installing a tube always inflate it enough that it's "filled out" but still quite limp.)

comment Minimum tire width to avoid snake bite
@Carel - Tire width certainly figures into the equation, no?

comment Minimum tire width to avoid snake bite
If you're getting snake bites either you're jumping too many curbs or your tire pressure is too low.

The exercises for stamina and cadence are kind of at odds with each other.

comment got a sears robuck three wheeler need axel
The problem is that there are about ten different ways this bike may have been built. Without pictures or a more detailed/accurate description we can't offer much advice.

Your description is inadequate for us to understand what the specific problem is. (Pictures would be very helpful.)

comment My cycle's gears don't change properly
You adjust the derailer. The symptoms you describe suggest that the cable tension needs adjustment -- something that every semi-serious cyclist should know how to adjust.

comment Electric bike rear wheel spokes breaking
Yeah, those spokes are so short that it's probably hard to find standard ones that length (and thickness) and if one did there would still be some problems lacing them. The scheme shown "should" work, but the devil is in the details -- making reliable spokes is a fine art.

comment Bicycle crank is wobbly
There are several options. You basically need to know you want one for a "square taper" bottom bracket. CCP-22 is one of several that Park sells that will do the job.

comment Replacement of sprocket
@zenbike -- 900-1000 miles for a cassette??? Maybe if you only ride on a sandy beach.

comment Replacement of sprocket
They should be replaced when they are worn out. Every serious cyclist should have a chain wear gauge. Your better bike shops have a wear gauge for sprockets, but a common test for the front is to see how far you can pull a relatively new chain off the sprocket. Generally chains are good for 2000-3000 miles, rear clusters about twice that, and front rings every 2-3 rear clusters. But a worn chain causes sprockets to wear much faster.
