Check that your front wheel quick release or axle nuts are tight.
Squeeze the front brake lever and check that the brake pads align squarely on the rim. Lock the front brake and pull the bike back, the wheel should skid. Also check the brake cable for cuts or kinks.
Pick up the front of the bike and spin the front wheel. Check if the wheel wobbles from side to side. Check the tire wear and brake pad clearance from the rim. If you have fenders or a handlebar bag, make sure these do not rub on the tire.
Apply the front brake and try to rock the front wheel back and forth. If you feel any play, your headset might be loose and will need adjustment.
Repeat steps 1 through 3 for the rear of the bicycle.
Grab the crank arms and try to push them in and out to check the crank arms and bearings for looseness. There should be no lateral play in the crank axle. Also check that the pedals are screwed in all the way, flat against the crank arm.
With the rear wheel off the ground, turn the pedals and shift through the gears. Make sure the derailleur can reach all your chainring combinations and does not throw the chain off the front or back sprockets. You may need to make a cable adjustment or adjust the derailleur screws.
Try hard to twist the saddle up and down, and left and right. If it does not move, it is secure.
Do the same to your handlebars, bracing the front wheel between your knees. Put all your weight on the handlebars when twisting up and down to make certain they will not slip in an emergency stop.
Check other attachments, nuts and bolts to make sure nothing is loose or might rub against your tires.
Check your tire pressure with a gauge. Keep your tires pumped up to the recommended pressure marked on the tire.
