My new moongoose mischief keeps
My first thought about the chain continuuin to become loose, is that you need to loosen the nuts on the back wheel, and pull the wheel (while the chain is still attached to bot hsprockets) in order to remove any slack. If it's a continuous issue, chances are that back tire keeps migrating forward because those nuts aren't tight enough.
To the pedal issue-If the pedals are wobbling or vibrating because the aren't snug while on the pedal bar (the bar that the pedals revolve around) it is probably because the peddals are too large. Try buying a new set of pedals. If they are loose and trying to slip off of the pedal bar and if you have tightened the nuts that keep the pedal on the pedal bar and they are continuing to become loose, it could be that you need to use locking nuts.
A quick fix to solving loose pedals is to add washers to the end of the bar until the washers are flush up against the pedal and the nut.
Happy pedaling!

Adjust rear shock(soften) mongoose ledge 2.1
Understanding Sag
In order to let the suspension work properly, we allow some of the rear-wheel travel to be used when supporting the rider's weight, this is called 'sag'. The basic idea is to have around 10-20% of your bike's total travel as sag. This allows the rear wheel to drop into dips in the trail and maintain contact and traction.
Adjusting Sag on Rear Suspension
Changing the amount of sag in the rear suspension is done by increasing or decreasing the spring rate of the rear shock. The rear shock's body is threaded and you will notice there is a nut on one end of the spring. Turning the nut in the direction that compresses the spring will increase the spring rate and reduce the amount of sag. Turning the nut in the direction that expands the spring will decrease the spring rate and increase the amount of sag. Never turn the nut to the point where there is space between it and the spring, this may cause damage to the shock.
How old is this mongoose bike Serial number HYEB00689
Google "mongoose serial number". That is what anyone here would have to do to answer your question. You may or may not be able to determine the age from serial number, but bike condition is far more important than age..
