You need a a spoke wrench to get the spoke out of the spoke nipple by the rim. The nipple screws on and off just like a regular nut. Undo the nipple and bend the spke a little until it pops free. Unlace the spoke from where it's intertwined with the other spokes until it can be released from the hub. Bring the spoke with you to thebike store and buy a replacement, then repeat in reverse. Tension spoke until it gives of the same tone as the other spokes then plucked.
put my mum on the seat and grind
Change the wheels with specil ski wheels i think its called ski bike.
axle mounted, yes.
A 20 inch tire.
It´s the Stem, it holds the bars and match with the frame with the help of a headset.
Yes, pegs can be put on any BMX Bike. You will need a socket wrench to put pegs on certain bikes how ever.
Depends on what's already on there, what's available, and how much clearance the bike has at the fork and frame.

u could cut it up then make all the bits smaller and then put weld it back together again
Not a sprocket only, but you can buy a 23-tooth freewheel that should fit.
Depends on what you mean and what the different bikes are like.If you really mean hub:The hub is the center part of the wheel, that holds the wheel axle and the spokes, and in some cases the brake rotor.Most 26" MTBs these days use dic brakes, while BMXes mostly use rim brakes. And to be able to fit a brake rotor to the finished wheel, you need to start with a disc brake hub, which a BMX hub is unlikely to be.But using a rim brake BMX hub to build into a rim brake MTB wheel - no problemAlso, most MTBs use 32 spokes, while for BMX, 36 spoke is more common. You need to match hub spoke count to rim spoke count to avoid complicated builds.If you mean wheel:BMX regular size is 20" against MTB regular size 26". You'll get all sorts of troubles by dropping 6" from the wheel diameter. The bike will handle differently, and the pedals will drop a lot closer to the ground.
Probably. Today BMXes can have either a freewheel hub or a cassette hub, but as long as you stay within the hub type you can move parts from one bike to another.
