Buying consideration for BMX crank

Several types of cranks:
It is key to remember that there have four main types of crankset from several brands. These are known as 3-pieces, 2-pieces, 1-pieces, and race cranks. In most cases, 2-piece and 3-piece cranks are similar if the spindle size is compatible with the crank's size. Also, these cranks are made of Chromoly.
On the other hand, the racing bike cranks are made from aluminum alloy. And there have lower bottom brackets with the racing cranks.

Racer cranks: These cranks are used for MTB bikes. Because MTB needs different cranks style with enough burden saving power. These cranks are made from aluminum material. And you will get these two pieces and a three-piece design.
Crank size: Crank size is depending on two main factors, one is the crank length, and another is the bottom bracket size. Here the bottom bracket refers to the distance from the center to the spindle center. Although there has crank size available from 140 to 190 mm, most of the BMX bike comes with 170 to 175 mm cranks. So, we recommend using a crank within this range. And consider 19 and 22 mm for the spindle radii.
Materials: The freestyle BMX cranks are made from Chromoly and steel. So, it can provide high strength from combined material. And, the racer cranks are mainly made from aluminum. However, you will get some carbon fiber racer crank.
Heat treatment: It is a function of crankset which comes from the manufacturing brand. Heat treatment refers to the power to stand against the height speed and forces.
Price: You have to pay 10$ for the basic 1-piece crankset. And the 3-piece crankset price starts from 35 $ to 400$. Don't worry about the 3-pieces price range. There has some best 3-piece crankset for BMX bike of 35 $ to 100 $.
