In this case, you’ll need to identify the type of crank for your bike. If the part is a single unit that’s one piece, it’s a single-piece crank. If it’s made up of three or more distinct sections, it’s a two-piece or three-piece.

Other considerations to consider when buying BMX pedals

Although getting the BMX size you want is essential, it’s not the only aspect to think about when shopping for BMX pedals. Also, it would be best if you considered the following elements:

(a) Pedal Type

Typically, BMX pedals come in two kinds: flat/platform and clip. In general, platform pedals are the most sought-after option because they provide a more excellent surface for feet to sit on and are typically more durable.

Their main issue is that they do not allow the user to control the foot’s pressure in a way that encourages acceleration. Therefore, they’re not the most suitable option for racing BMX bikes, but they are ideal for stunts.

If you’re looking to accelerate more and avoid doing more stunts, the right pedals you should consider are clips. Clip pedals are usually the simplest to set up and are more suited to beginners. However, they are less robust than platforms.

(b) Material Type

Most BMX pedals are steel, aluminum, plastic, and nylon. Nylon can withstand weather elements better and has more vibrant colors and vibrant, while plastic provides the lowest-cost alternatives.

However, pedals made of aluminum alloy are stronger and more lightweight (though they aren’t as durable as plastic), and steel pedals are more robust.

It’s up to you to determine what is most important to you. If you cannot choose, then you should go with aluminum. One pedal that is sure to please can be found in The SE Bear Trap BMCX pedal (View the item on Amazon).

This pedal set comes in a strong aluminum body and is light. It’s also available in various colors and works with 3-piece BMX cranks. The most significant thing is that its price is less than $50, which makes it much more affordable.

(c) Pedal Grip

While there aren’t every BMX pedal comes with textured surfaces, it’s recommended to think about alternatives. A pedal with a texture will provide more grip, which makes it easier to race and perform your stunts. If your pedals do not give adequate traction, you must wear shoes with high traction.

(d) Pedal Attachment

The attachment (the point that connects it to the bicycle) is a crucial aspect to consider when purchasing replacement BMX pedals. Typically, these pedals can be clipped or screwed in place. In general, a screw attachment gives a more substantial grip over clips.

Certain BMX pedals have higher-quality pedals than others. This is why you should consider the pedal manufacturer with good reviews.

Some notable names in the BMX sector are 25NINE, SE Racing, BEKEIN Pro, Rockbros, and Darer.

(f) Budget

The cost of the pedals can reveal whether you’re purchasing good high-end BMX pedals or a less expensive selection. You can expect decent high-quality BMX pedals to cost between $30-$50 or slightly higher. You may, however, get a few good choices averaging $16 – $25.

(g) Maintenance

Find BMX pedals that are easy to maintain easily. They ought to be easy to clean and less prone to corrosion. In this case, the options with curvy components or larger openings are a good choice since they let you remove the dirt.

Plastic, nylon, and aluminum alloy resist rust, which makes them excellent options.

Are BMX Pedals Universal?

There aren’t all bicycle pedals that fit on all bicycles. The pedals typically come in 1/2-inch and 9/16-inch alternatives that are expressed as 1/2′ 20 TPI (12.7 12.7 x 1.27mm) or 9/16″ 20 TPI (14.28 1.28 x 1.27 mm) in each case.

The distinction is that 9/16-inch pedals are only compatible with BMX bikes, children’s bikes, and older cruisers. 9/16-inch pedals, by contrast, are modern pedals that work with the majority of adult bikes, such as MTBs and road bikes, and BMX bikes.

This is why most people describe 9/16-inch pedals as universal or standard. Some examples of such pedals include the BIKEIN Pro 9/16″ Platform Pedals and the HYSENM flat Adult 9/16” Pedals (View the complete list on Amazon).
