You didn't say what kind of bike, coaster brake maybe?
1. if it has hand brakes, check to see if they are rubbing on the rim
2. You may need to pull the wheel off, the axel bearings may be too tight or need to be greased
3. If coaster brake the brake may not be disengaging
If you are good with tools you can do this for each of the above:
1. center the brakes and tighten in place
2. disassemble the bearings clean, grease and adjust to spin smooth and freely
3. coaster brakes have quite a few pieces you may want to take in to a shop.
Finally the number 1 reason a kid's bike is slow - the tires are almost always very low on air. (this is not your problem here)

I'm not going to put you down for the bikes you like, so heres my thoughts so heres what you have the frame is a little small for you on both bike, as they are both 53cm frames but by raising the seat higher your legs should still extend, but it's not the best riding position here are the two main differences in the bikes the mongoose is an alloy frame and steel fork (i think) while the genesis is steel framed, the alloy frame mongoose may be lighter then the genesis but the genesis has curved bars over the the mongoose Straight bars.... if your just riding this around town i would go with the mongoose happy riding

Sounds like the pawls might be gummed up. You don't want to take that apart but might try squirting some brake cleaner in there, let it soak for a day or so then use a nice light oil - not wd40 - and let plenty of it drip in there.
It's not exactly what they say in the tech manual but without proper tools it might work.
Otherwise, it's a trip to the bike store, maybe a simple take apart and overhaul, maybe a new freewheel, maybe a new hub/wheel.

try getting a book about fixing the style of bike you need to fix.
Its alot easier to bring the bike into the shop so they can tune it right up and make sure everything is safe still. For instance, i tried truing a rim once, it took me over 2 hours and i made it worse, brought it into the shop and in 10-15 minutes for 10$ i had a perfectly straight wheel again. good thing i practiced on an old rim before diving into my good one. (and by the way i was reading a book on how to straighten a rim while trying to fix it)

go to a local bike shop and ask about the tools to loosen the rear chainwheel and get them, just happened to my dads bike, or you could even use a wrench in some cases. it's the thing in front of the sprocket if you take off the tire, loosen it a tiny bit and it should be fine.

Check if the brake pads are rubbing on the wheel. He could also have a bent rim.
