8 Best BSD BMX Frames For Every Riding Style

BSD has one of the strongest BMX frame lineups if you like having real geometry choices instead of a bunch of frames that all feel almost the same.

Some are short, sharp, and built for technical street riding.

Others are longer, calmer, and better suited to speed, bigger gaps, trails, bowls, or riders who simply want more room on the bike.

That variety is what makes BSD frames so interesting.

Instead of choosing by colorway or rider name alone, I’d pay close attention to the head tube angle, chainstay length, standover, bottom bracket height, and top tube size.

Those numbers will tell you a lot about how the bike should feel before you even build it.

Below, I’ll break down the current BSD BMX frames for different riding styles and explain where each one stands out.

If you already know whether you want something quick, stable, roomy, or ultra-responsive, picking the right BSD frame gets a whole lot easier.

Best BSD BMX Frames

1. BSD ALVX AF+ Frame

Alex Donnachie’s ALVX frame has been a staple of the BSD frame lineup for years.

The latest iteration features an updated chainstay that integrates an investment cast yoke.

It allows for larger tire clearance even at the short as possible 12.5” slammed length and stiffens up the rear end of the bike.

This frame also has investment cast dropouts with built-in chain tensioners and external gussets on top and down tubes.

The ALVX frame is a BRAKELESS frame and is available in 4 different top tube lengths.

ALVX frame specs:

• Top Tube Length: 20.3”, 20.6”, 20.8”, 21”, 21.2″
• Head Tube: 75.5° / 117mm
• Seat Tube Angle: 71°
• Chainstay Length: 12.5”-13”
• Standover: 8.7”
• BB Height: 11.7”
• Weight: 5lbs
• Price: $459.99

2. BSD Freedom Frame

The Freedom Frame from BSD is Kriss Kyles’s signature frame. This frame is made to be well-rounded. Perfect for all types of riding just like Kriss does.

This one has a very low bottom bracket height at just 11.5” as well as a steeper head tube angle at 75 degrees and a shorter rear end.

All of these combine to give this frame a VERSATILE geometry.

The Freedom frame utilizes an investment cast wishbone which helps allow for better tire clearance as well as stiffness in the rear triangle of the frame.

In addition to its versatility in geometry, this one comes in 5 different top tube lengths ranging from 20.2” to 21.5”.

Freedom frame specs:

• Top Tube Length: 20.2”, 20.5”, 20.8”, 21.1”, 21.5”
• Head Tube: 75° / 117mm
• Seat Tube Angle: 69.5°
• Chainstay Length: 13.2”-13.625”
• Standover: 9”
• BB Height: 11.5”
• Weight: 5lbs
• Price: $499.99

3. BSD Focus Frame

Introducing Gaspar Guendulain’s signature BSD Focus frame – a fresh take on BMX frame geometry.

Designed for riders who want more room to move, it features a longer 13.5-14” rear end, a tall 10” standover (my fav feature!), and a unique 72° seat tube angle to make pinching the seat for barspins easier.

With top tube sizes up to 21.5” (Gaspar’s go-to), this frame is all about comfort and control.

Built with Sanko Japanese seamless 4130 CrMo tubing and heat-treated components, it’s strong, durable, and ready for serious riding.

Available in Wine Red and Flat Raw, the Focus frame is a perfect blend of style and performance!

Focus frame specs:

• Top Tube Length: 20.8”, 21”, 21.2”, 21.5”
• Head Tube: 75.2° / 123mm
• Seat Tube Angle: 72°
• Chainstay Length: 13.5”-14”
• Standover: 10”
• BB Height: 11.7”
• Weight: 5lbs
• Price: $439.99

4. BSD Tweeker Frame

Tweeker is Antonio Smallwood’s signature BSD frame, built for fast, technical street riding.

The geometry is properly aggressive: a 75.6° head tube, super-short 12.6–13.1″ rear end, 11.7″ BB, and 9.1″ standover. That should give the bike a very quick, reactive feel for spins, nose manuals, and tighter street lines.

One detail I really like is the 72° seat tube angle. BSD moved the seat slightly further forward compared to a more common 71° angle, specifically to make seat pinching easier for barspins.

That’s the kind of small geometry change that actually reflects how Antonio rides.

The frame is built from triple-butted Sanko Japanese seamless 4130 chromoly and uses an invest-cast chainstay yoke for extra tire clearance and stiffness.

You also get 7mm dropouts with integrated chain tensioners and a grind-friendly shape that avoids unnecessary overhang.

If you like a bike that reacts immediately and you spend most of your time on technical street, the Tweeker is one of the sharpest options in BSD’s lineup.

Tweeker frame specs:

• Top Tube Length: 20.6”, 20.9”, 21.2”
• Head Tube: 75.6° / 117mm
• Seat Tube Angle: 72°
• Chainstay Length: 12.6”-13.1”
• Standover: 9.1”
• BB Height: 11.7”
• Weight: 5lbs
• Price: $459.99

5. BSD Safari Frame

Reed Stark’s signature Safari frame from BSD saw a few upgrades over the previous version. The frame utilizes BSD’s new Superscoop chainstay tubing.

This tubing allows for additional tire clearance even when the wheel is slammed all the way forward. Reed is a tall guy so he needs a frame that fits him.

The Safari frame comes in 20.6”, 21”, 21.4”, and 21.8” to accommodate that for him as well as other taller riders around the world.

There aren’t a ton of other options in BMX for frames as large as 21.8.” If you need a longer frame that also has normal, modern geometry, BSD’s Safari frame could be the one for you!

Safari frame specs:

• Top Tube Length: 20.6”, 21”, 21.4”, 21.8”
• Head Tube: 75° / 123mm
• Seat Tube Angle: 71°
• Chainstay Length: 13”-13.5”
• Standover: 9.5”
• BB Height: 11.75”
• Weight: 5.3 lbs
• Price: $439.99

6. BSD Sureshot Frame

The Sureshot frame from BSD is their offering for ramp, park, and trails.

The frame has a mellower head tube angle and a medium length chainstay which both add to the stability of the frame for things like trails and transition riding.

Another element of stability associated with these types of riding is the bottom bracket height.

The Sureshot has a lower bottom bracket height which LOWERS the rider’s center of gravity; making a more stable feeling frame.

Bringing all of these together in one makes for a frame that is well rounded for just about anything you might want to do with it short of the extremely technical modern street riding.

Sureshot frame specs:

• Top Tube Length: 20.7”, 21”, 21.3”, 21.7”
• Head Tube: 74.75° / 117mm
• Seat Tube Angle: 71°
• Chainstay Length: 13.4”-13.9”
• Standover: 9”
• BB Height: 11.5”
• Weight: 5lbs
• Price: $439.99

7. BSD Jonesin’ Frame

Yes, BSD’s Jonesin’ is the very signature frame of tech wizard, Sam Jones. If you’re looking for a smaller frames that’s super responsive, well, this is the one.

It has a very steep front-end at 76-degrees for all the crazy nose stuff that Sam does. And you can, too!

And I guarantee your spins will be a lot simpler with the short chainstay. Plus, it’ll be a lot easier getting into a manual, too!

Jonesin’ frame specs:

• Top Tube Length: 20.4”, 20.6”, 20.8”, 21”
• Head Tube: 76° / 117mm
• Seat Tube Angle: 71°
• Chainstay Length: 12.7”-13.2”

8. BSD Grime Frame

The Grime Frame from BSD is Denim Cox’s signature frame which has some awesome decals that fit the name well.

Denim is a brakeless rider whose frame reflects WITH NO brake mounts or place for them in sight.

This frame also features external gussets on both the top tube/down tube and investment cast dropouts with integrated chain tensioners.

Speaking of investment cast, there is an investment cast seat post clamp and yoke on the chainstay which allows for clearance of B tires while also stiffening the rear end of the frame.

Grime frame specs:

• Top Tube Length: 20.6”, 20.8”, 21”, 21.2”
• Head Tube: 75.5° / 117mm
• Seat Tube Angle: 71°

How To Choose A BSD BMX Frame

The most important thing to look at is the top tube length (TT) measurement.

Check out my in-depth guide on picking the right BMX frame size, where you can find a convenient chart.

Next up is BMX frame geometry.

You basically need yourself to ask the following: Do I need a stable or a responsive frame?

And it all goes from there.

A stable frame will have a mellower head tube angle, lower bottom bracket height and longer chainstay length.

On the other hand, a more response frame will have a steeper head tube angle, usually higher bottom bracket height (for grind clearance) and shorter chainstay length.

Also, riders who prefer a stable frame also generally pick a longer TT compared to technical wizards.

Conclusion: Which BSD Frame Fits You Best?

If you want something super quick and technical, the ALVX AF+ is one of the sharpest options in the lineup.

The Tweeker also leans heavily toward technical street, but with its own Antonio Smallwood-inspired geometry and slightly different feel.

Want more balance? The Freedom is the easiest all-around pick and works well if you ride a bit of everything.

The Focus goes in the other direction with a much longer rear end and taller frame, making it a strong choice if you like technical street riding but still want extra stability.

For taller riders, the Safari is hard to ignore thanks to its longer top tube options and roomier setup.

The Sureshot is the one I’d look at for park, trails, and transition riding, while the Jonesin is a great choice if front-end tricks and quick handling are high on your list.

And if you want a proven street frame with aggressive geometry, the Grime still holds its own.

In short, look at the chainstay, head tube angle, standover, and top tube size, then choose the frame that matches the way you actually ride.
