2nd Method

Take off your shoes and stand with your legs about 15-20 cm(6” – 8”) apart.Measure the height from the ground to your crotch.
Be sure of the type of bicycle you want: Mountain bike, city bike or road bike. You can read  about the different bike types from here.
Now you can take your calculator and calculate the right size:
[Leg Inseam method]

City bike – Leg inseam (cm) x 0,685 = Your frame size
Mountain bike –  Leg inseam (cm) x 0,66 = Your frame size
Road bike – Leg inseam (cm) x 0,70 = Your frame size

(If your leg inseam is 76cm, then your right mountain bike size is 50 cm (20”), road bike 53cm and city bike 52cm)


Frame-set: In aluminum frames, look for significant dents. These can act as failure points. Carefully check the lugs or welds where the frame is joined together. Welds should be even. Cracking of any kind is a show-stopper. So are bends at the dropouts (where the wheels attach to the frame). There should be no play in the front fork, in other words, no wiggling.

Saddle or Seat: There should be no play whatsoever. Verify that the seat post clamp is free of cracks or obvious distress.

Brakes: Check for worn or dried-out brake pads. Look for cracked or bent brake levers.

Drive-train: Wiggle the crank-set. Side-to-side play indicates worn bearings or an improperly adjusted bottom bracket. The same applies to pedals. If possible, spin the free-wheel or cassette and listen for the chatter of broken bearings. Lift the rear wheel and verify that shifting is crisp through all gears. You should be able to shift into the largest and smallest rear gear without the chain jamming or becoming un-shipped. On bicycles with rear derailleurs, inspect the rear brake hanger for bends or cracking.

Wheels: As with the crank-set, side-to-side play in a bicycle wheel indicates poorly maintained hubs. Squeeze the spokes with your fingers. The tension should feel equal across the entire wheel. Loose spokes indicate serious problems.

Tires:  Are they well inflated? Are they bald? Are the sidewalls cracked and perished? Tires should be inflated hard – they should barely give when you squeeze them.  Tires should hold the rated sidewall pressure.Chain:  If the chain is rusty, look for areas around the chain that may be cracked or worn down.
