The forks are the parts of the bicycle frame to which the wheels are attached.
The fork of the bike is where the front tire is placed.
Depends on what's already on there, what's available, and how much clearance the bike has at the fork and frame.
It should be on the frame area where the fork connects.If you can't find it your bike may be stolen!
The fork Crown is the part where the two fork legs are joined to the steerer tube, the part that goes through the head tube of the frame.
Fork motorbike is a bike that connects a motorcycle's front wheel and axel to its frame, typically via a pair of triple clamps. It typically incorporates the front suspension and front brake, and allows the bike to be steered via handlebars attached to the upper triple tree.
Not w/o folding the rear seat, and even then it probably requires popping the wheels out of the frame/fork.
There are plenty of important parts on a bicycle. W/o any of these the bike wouldn't work. The main parts are wheels, frame and fork.
If My memory serves me right you will find it is usually found on the left side of the frame where your Tripple Tree (Handle Bar fork assembly) Bearing Tube, is welded to the frame of your Bike .
Theres' really no telling. If you are talking about taking the fork off a 21" frame size MTB and sticking it in a 16" frame size MTB, then the answer is - probably. But there are a couple of different steerer tube diameters, and they have to match. You also need to consider fork travel, or axle-to-crown measurement. Get the axle-to-crown wrong and you'll change the handling quite a lot, and you will put a bigger bending load on the fork.
That's a BMX, and there's not a lot of difference between forks for those. AS long as you get the correct steerer tube length, any BMx fork would give you a rideable bike.
That'd depend on where you're starting from. If you've got a finished frame, fork and wheels, then you can certainly put it together in one day.
