the chain stay is the part of the frame thats nearest to your chain, and often gets big gashes in it from your chain hitting it. often people have something covering there chainstay to protect it from the chain hitting it.
Frame - the main structural part of the bicycle, commonly made of steel, aluminum, titanium, or carbon fiber. Composed of a top tube, head tube, down tube, bottom bracket shell, seat tube, seat stays, and chain stays (see image). A frame and fork sold as a combination are referred to as a frameset.
It wasn't that long ago that frames were made out of cast iron or even wood. Today bicycles are made out of exotic materials such as titanium, aluminum, and carbon fiber. Bicycle frames in the 1990s are lighter and stronger than ever before. A racing bicycle frame with parts of the frameset indicated.
Seat StaysThe seat stay connects the seat tube to the rear dropout. Most bike frames use two parallel tubes that connect above the rear wheel. This is also the spot on the frame where the rear brake caliper is attached.
Bicycles wheels often feature quick-release levers at the hubs that hold the wheel on. The quick release is a cam mechanism that holds the wheel tightly in place and makes it possible to remove the wheels without tools.
The round shield around the head of the crank arm is a friction/interference fit against the body of the chainguard. You should be able to pop it off with a screwdriver blade or similar. Opening should be large enough to remove crank arm with chainwheel.
These chains are lubricated using vaccum pressure and the oil stays inside chain for longer. Thus the cover is not required. Also the friction is less because of O and X rings within the chain teeths. Also these chains are used in performance bikes are way durable and rugged than non O ring chains.
Bash guards are used on gravity and trail bikes to prevent rocks, logs and other trail or racetrack obstacles from damaging chainrings. They usually consist of circular discs attached to the chainset in place of the large chainring, and are built of tough aluminium or polycarbonate that can absorb impacts.
"do i need the plastic spoke protector?" Yes, if you want to look like a complete noob. Lose it. If your rear derailleur upper set screw is properly adjusted, the chain isn't going past the large cog.
Chain guides are typically used in conjunction with a bash guard, an alloy or polycarbonate plate that is fitted to the chainset in place of the largest chainring and which prevents rocks, logs and other trail or racetrack obstacles from damaging chainrings.
Bicycles turn energy created by our bodies into kinetic energy. A bicycle can convert up to 90 percent of a person's energy and movement into kinetic energy. This energy is then used to move the bike. The rider's balance and momentum help keep the bike stable while traveling along a path.
Bike is shorthand for a bicycle or a motorbike. Bike is also a verb, so you could say: "I'll bike over to the movie theater — meet you there in fifteen minutes!" This word, as a nickname for bicycle, first appeared in American English in 1882. It came to mean "motorcycle" about 50 years later.

As others have said, the push in "push bike" refers to having to push on the pedals to make it move. It only came about to distinguish from motorized versions once they became a thing. Lots of things get named like this, and then the extra adjective gets dropped after (if) it they become the dominant form.
A bicycle is a physical system because there are several parts which work together to perform a function. Essentially, it is easier to think it as a system because it gives a better understand of the man-made object, the bicycle and how it works to perform certain tasks.
A cylinder with desmodromic valves may have three or even four camshafts. An OHC or DOHC cylinder head will have at least two valves per cylinder (1 inlet and 1 exhaust), but multi-valve engines may have three (2 inlet and 1 exhaust), or four (2 inlet and 2 exhaust), or even five (3 inlet and 2 exhaust).
If you'll stay on pavement and ride primarily for exercise, a road bike or fitness bike is a good choice. A comfort or cruiser bike is better for short, casual rides with family. If you'll bike mostly for commuting, a city bike might be best; think about electric pedal-assist models as well.
Biking is a top-notch cardio workout. You'll burn about 400 calories an hour. Plus it strengthens your lower body, including your legs, hips, and glutes. If you want a workout that's gentle on your back, hips, knees, and ankles, this is a great choice. You can cycle on the road, a bike path, or a mountain trail.
Requirements: Bike must be properly packed in a hard-sided bicycle box that fall within the dimensions and weight limits established for normal checked baggage. Pedals and handlebars must be removed and packaged in protective materials so as not to be damaged by or cause damage to other baggage.
Different airlines will treat bikes differently, with some accepting bike bags as part of your baggage allowance (albeit) outsized, while others will require you to pay a surcharge on top of your flight cost to be able to carry your bike with you.
The bike shop employees will help you package your bike. Go to FedEx's website (www.fedex.com) and choose the "Prepare Shipment" option found under the "Ship" menu tab. You will first be asked to sign into the site under your account or create a FedEx account if you do not already have one.
For checked-in luggage booked and prepaid online, they charge $15 for 15kg and $17.50 for 20kg. Our extra cost: $150 (10kg hand-held, 15kg checked-in, bike fee, $75 each way). Virgin Australia (Virgin Blue) used to be very bike-friendly, but it is not so much now.
Most cyclists prefer to ship a bicycle through a traditional carrier service, even if they're flying to the same destination. When you factor in baggage fees and the hassle of TSA inspections, it's hard to beat the cost and convenience of packing a bike in a cardboard box and shipping with FedEx or UPS.
