United is a Hastings, UK-based BMX brand that Ian Morris started in 2006 alongside 4Down Distribution.

But we are not here today to study history.

But to check United’s CURRENT frame line.


  • Alex Valentino’s signature United Frame: Auto Portrait
  • Miki Fleck’s signature United Frame: ZUIN
  • Best United All-Around Street Frame: Incarnate

It’s a bit of a mix of responsiveness (snappy) and stability (mellow) to cover as many riders as possible.

Get cracking.

Best United BMX Frames

Note: Frames are listed in no particular order. (The 1st one is not necessarily better than the 3rd one – they’re all fantastic!)

1. Auto Portrait

Alex Valentino’s signature United Auto Portrait frame is a mixture of new and old. The frame comes in four different top tube lengths and three color options.

It has a steep head tube angle with a somewhat low stand over, at 8.6″ (to today’s standards).

Some other features of the frame are double wishbone design, invest cast drop outs and included seat clamp (not integrated).

The graphics are minimal but dope. If you want a French-inspired frame, this is it.

“By acquiring Autoportrait you’ve got yourself a piece of art.” – Alex

Auto Portrait specs:

  • Top Tube Length: 20.5″, 20.8″, 21″, 21.25″
  • Head Tube: 75.5°
  • Seat Tube Angle: 71°
  • ChainStay Length: 13″ Slammed
  • Standover: 8.6″
  • BB Height: 11.8″
  • Weight: 5lbs
  • Price: $359.99 (may vary)

I’m sure you’ve all been waiting for this one, the all-new Miki Fleck signature ZUIN frame. You know this frame is meant to last, knowing the style of Miki’s riding.

The frame is inspired by Incarnate but with a longer (thickened) chain stay and higher bottom bracket height.

Yup, Miki definitely needs thick chain stays, or he’d grind through them too quickly.

It also includes integrated chain tensioners, removable brake mounts and tapered tubing.

Go fast and go big with the ZUIN frame – comfortably!

ZUIN specs:

  • Top Tube Length: 20.5″, 20.75″, 21″, 21.25″
  • Head Tube: 75.3°
  • Seat Tube Angle: 70.25°
  • ChainStay Length: 13.25 – 13.5″
  • Standover: 9.3″
  • BB Height: 11.6″
  • Weight: 5lbs
  • Price: $349.99 (may vary)

3. Incarnate

According to United, the Incarnate V2 frame is the “Second rendition of the bomb-proof Incarnate.”

The V2 of the frame features a thicker tube set to add to that strength, investment cast dropouts that are updated and have built-in chain tensioners.

The Incarnate has removable brake mounts but no holes drilled for gyro tabs. It also comes with external gussets on the top/bottom tubes.

This frame also has a mellower seat tube angle, which brings the bottom bracket forward, giving the bike a SMALLER feel without affecting the top tube length.

Seat tube angle isn’t widely discussed or adjusted in BMX, so this is a welcome feature. It is great that United educates about this on their site!

Incarnate specs:

  • Top Tube Length: 20.8″, 21″, 21.2″
  • Head Tube: 75.5°
  • Seat Tube Angle: 70.25°
  • ChainStay Length: 13″ Slammed
  • Standover: 8.75″
  • BB Height: 11.75″
  • Weight: 5 lbs
  • Price: $309.99 (may vary)

How To Make Your BMX Frame Last Longer?

How can I prevent rust and corrosion on my BMX frame?

To prevent rust and corrosion, regularly clean your BMX frame, especially after riding in wet or muddy conditions. Dry it thoroughly and consider using a frame protectant or a light coat of oil on metal parts. Storing your bike in a dry, covered area also helps in reducing exposure to moisture.

Is it important to regularly check and tighten the bolts on my BMX frame?

Yes, regularly checking and tightening the bolts on your BMX frame is crucial. Loose bolts can lead to undue stress and damage to the frame.

Can customizing or modifying my BMX frame affect its longevity?

Customizing or modifying your BMX frame, such as drilling holes or welding on additional parts, can compromise its structural integrity and shorten its lifespan. In short, I don’t recommend doing any mods to your frame.

How can I reduce the impact on my BMX frame during rides?

Learn and practice proper landing techniques to distribute impact forces evenly. Also, ensure your tires are correctly inflated to absorb shocks. (See this guide to learn about the best BMX tire pressure.)
