A Throne bike is easy to fall for and surprisingly easy to set up wrong. The colors are loud, and the wheelie appeal is obvious, but small details like axle size and tube width decide whether the first month is smooth or full of return labels. Riders searching for throne bikes usually need help with three things: which model, which wheel size, and which parts go on first.
This guide from Billet BMX covers the current lineup, the 26 versus 29-inch decision, the 3/8 inch versus 14mm axle question, and the upgrades worth making early.
What Throne Cycles Offers at Billet BMX
Billet BMX carries a deep Throne catalog, with dozens of bikes and parts on the collection page. The headline model is the Goon, sold in 29 inch and 26 inch versions. A Goon Runner version sits at a higher price tier, and a 27.5 inch XL Runner fills the gap between the two wheel sizes. The Dime MTX line runs alongside as a separate model family. Riders who want the full story on the frame itself can read this Throne Goon guide, which stays focused on the bike's design.
Beyond complete bikes, the Throne bike parts collection holds 2 Wheel Gang inner tubes, four-piece handlebars, 33T chainwheels and Vee tires, plus Billet BMX hardware made for the same bikes. Collection copy describes the 29 inch Goon as built for wheelies, street riding, and big-wheel cruising, with hydraulic disc brakes. For background on why Throne bike parts keep gaining attention, this article adds context.
Throne Goon 26 vs 29 Inch: Choosing a Size
Wheel size shapes how a Throne bike feels more than any color or graphic does.
Where the 29 Inch Goon Fits
The 26 inch version spins up faster, turns tighter and feels more compact under shorter riders. It gives up some of the smooth roll that a 29 inch wheel delivers, but it rewards quick, playful riding.
| Model | Wheel Size | What to Know |
|---|---|---|
| The Goon | 29 inch | Core model, described for wheelies, street riding and cruising |
| The Goon | 26 inch | Smaller wheel, listed in colors like White Chill and Black Strike |
| The Goon XL Runner | 27.5 inch | Sits between the two main sizes |
| The Goon Runner | 29 inch | Higher price tier, so compare listing specs closely |
| The Dime MTX and MTX-RX | 29 inch | Separate model family, check each spec sheet |
Riders still deciding can browse the wheelie bikes collection to compare options side by side.
The Axle Question: 3/8 Inch or 14mm?
Axle size is the detail most likely to cause a wrong order. Billet BMX splits Throne Goon parts into a 3/8 inch rear axle and a 14mm rear axle, which shows how much the standard varies between builds. The rear axle should be checked on the bike itself, using a caliper or the markings on the nut, before anything goes into the cart.
Once the size is confirmed, the matching hardware is simple. The Billet BMX chain tensioner pair for 14mm axles is sold as a two pack and listed for GT, Throne, and ZOOZ bikes. Deez Nuts axle nuts in 14x1mm cover the thread side, also as a two-pack. Riders on 3/8 inch axles need the 3/8 inch versions instead, and mixing the two is the classic mistake.
First Upgrades Worth Making
Chain Control
A sagging or slipping chain ruins a wheelie session faster than anything else. Tensioners hold the rear wheel in position so chain tension stays consistent, and they add color at the same time. Billet BMX offers the 14mm kit in a long list of finishes, from red and blue to gold, oil slick and chrome, so matching the bike's graphics takes no effort.
Hardware and Cockpit
Axle nuts and stem caps are small purchases with a big visual payoff. Billet BMX lists a Deez Nuts compression stem cap in M24x1.50, a thread spec that has to match the bike's compression setup, so measurements still come before color.
Tires and Tubes
A tube has to match the tire it lives in. The 2 Wheel Gang tubes come in 29 inch sizes labeled 1.95/2.125 and a wider 2.5 version, while the Vee Speedster 29 inch tire is listed at a 2.3 inch width. Riders should compare tire width against each tube's stated range instead of guessing.
Buying Smart: Stock, Colors and Budget
Throne inventory shifts quickly. At the time of writing, several bikes on the collection page show as sold out, while others, including the Goon 26 inch White Chill and the Goon 29 inch C Shadow Black, show as in stock. Availability changes, so the live listing is the only reliable check.
Budget help exists too. Billet BMX promotes interest free installments through Shop Pay and Affirm, with details on its financing page, and riders near Southern California can visit the showroom in Whittier to see parts in person.

Conclusion
Choosing a Throne bike comes down to size, axle standard, and how the bike will be ridden. The 29-inch Goon favors rolling speed and cruising, the 26-inch favors quick handling, and the Runner and Dime models add other options for riders who want to compare. Checking the rear axle first, matching tube to tire, and confirming stock before checkout keeps the build clean and the returns pile empty. The Throne Cycles collection at Billet BMX is a practical place to start.
