When you're shopping for a BMX bike for a kid, the real question is whether you need a complete bike or the missing part that brings an existing bike back to life. The four options here sit on both sides of that decision: two complete 20-inch freestyle bikes and two smaller purchases that upgrade or refresh a ride. Before you compare specs, it helps to know which side of that line you're on.
Quick Take
- The Costway Freestyle BMX Bike is the complete 20-inch package for a rider who wants to start learning bike tricks.
- The Tracer 20-Inch Wheels BMX Bike is a complete bike built for street, dirt, and park.
- The Term Gyro + Upper & Lower Cables is the old-school freestyle upgrade for restoring gyro function.
- The Cult Vans Gum Flangeless Grips are the simplest purchase here: a direct grip replacement for a BMX bike or scooter.
Listed-Price Comparison
Listed prices here run from USD 10.25 to USD 309.99, and the two completes occupy the top of that spread.

Product Notes
Freestyle BMX Bike, 20" Trick Bicycle with 270 Degree Steering, Adjustable Seat
If the goal is a complete bike rather than a parts upgrade, this Costway at USD 159.99 has the full package. It's a black, new BMX with a metal frame, 270-degree handlebar rotation, four metal pegs, and an adjustable seat. The treaded tires with a thickened hub design are meant for sidewalks, park paths, and dirt surfaces, and front and rear reflectors plus a bell add visibility. Assembly is required, so the bike arrives as a project rather than ready to ride. For a kid stepping up to a trick-style bike, this is the mid-priced complete in the comparison.
20" inch Wheels BMX Bike For Elite or Beginner Steel Frame Freestyle BMX Bike
This Tracer is the top-priced option at USD 309.99. The Hi-Ten steel frame, aluminum U-brake with alloy levers, sealed ISO bottom bracket with CrMo square axle, 9T driver, and 20 x 2.3-inch tires point toward riding beyond the driveway. The design suits both elite and beginner riders on street, dirt, and park, and the color is matte black. It's a bigger commitment in price, and the spec list reads like a bike a growing rider can keep progressing on. If you're willing to spend at the high end of this range, this is the complete to consider.
BMX BIKE 1" Gyro + Upper &Lower Cables Oyrg Fit Oldschool FREESTYLE BMX Bike New
This Term set at USD 24.99 is the upgrade piece for an old-school freestyle project. The set includes a gyro unit, upper and lower plates, and cables made of steel, plastic, and aluminum, and it's designed for bikes with a 1-inch head tube. It's compatible with brands such as Odyssey and with old dirt jumpers, hardtails, and OS flatland BMX bikes. It will not fit new school or mid school 1-1/8-inch head tubes. That makes it a precise purchase rather than a universal part. If your kid's bike matches that 1-inch head tube spec and needs gyro functionality, this 12-ounce set is a focused add-on.
Cult Vans Gum Flangeless Grips BMX Bike / Scooter Waffle Pattern - Brown/Tan
At USD 10.25, the Cult Vans grips are the lowest-priced item in the group, and they solve a specific problem: worn or missing grips on a BMX or scooter. These flangeless grips have a waffle pattern in gum rubber with black end plugs, measure 150 mm long with a 31.5 mm diameter, weigh 97 g, and use a slip-on installation type. They're made by ODI in the USA and include Cult nylon end plugs. Compatibility spans bikes from BMX and kids' bikes to dirt jumpers, mountain bikes, and folding bikes, plus scooters. If the bike is fine and the only issue is the hand feel, this is the simplest purchase here.
Final Recommendation by Use Case
- Buy the Costway Freestyle BMX Bike if you want a full 20-inch bike ready to become the starting point for trick practice, and plan for the assembly step.
- Buy the Tracer 20-Inch Wheels BMX Bike if the rider is ready for a higher-priced complete with a spec list that suits riding beyond the driveway.
- Buy the Term Gyro + Upper & Lower Cables if the old-school frame in the garage has a 1-inch head tube and needs gyro function restored.
- Buy the Cult Vans Gum Flangeless Grips if the bike is fine and only the grips need replacing.
