Sunday EX BMX Bike (Erik Elstran) Review

1. Key Features Of The Sunday EX

What makes the Sunday EX bike pop is its strength, thoughtful spec list, and no-compromise construction.

You get amazing quality at a mid-range price, which makes it perfect for serious (progressing) beginners or seasoned riders looking for a dependable ride.

Here’s what makes it shine:

• 100% chromoly frame, fork, and bars: Built to take heavy hits without a problem.
• Sunday signature wave down tube: More dent-resistant and stiff – it’s a solid upgrade.
• Odyssey C5 cassette hub: Clean, responsive, and dependable – ready for street and park abuse.
• Odyssey Stage 2 rims: Super strong, double-wall rims that can take a beating.
• Odyssey Path Pro 2.4″ tires: Great grip and ideal width for modern riding.
• Sealed hubs (front & rear): Less maintenance and smoother rolling.
• Sunday Seeley grips and Freeze stem: Adds that dialed finishing touch.

Honestly, it’s a well-rounded complete that rocks for under $700.

3. Sunday EX Bike Geometry

Frame Geometry:

• Top tube length: 21″
• Head tube angle: 75°
• Seat tube angle: 71°
• Chainstay length: 13.2″ – 13.5″
• Bottom bracket height: 11.5″
• Standover height: 9″

Handlebar Geometry:

• Rise: 9″
• Width: 29″
• Backsweep: 12°
• Upsweep: 3°

The 21″ top tube is ideal for medium to taller riders.

The shorter rear end and steep-ish fork offset give you that responsive handling – but you still get the necessary control.

I also really like that Sunday went with a 9″ standover height because it just makes the overall bike look better.

4. How The Sunday EX Bike Rides

This bike rides like a full-on street destroyer.

It’s responsive but not too twitchy, which means you can tech around on rails, spin out of grinds, and still feel locked in during manuals.

Ride the chainstay at 13.5″ length for more stability or 13.2″ if you want it more responsive.

The shorter 165mm cranks keep things more comfortable, even just when it comes to bunnyhops. But I find shorter cranks overall better, especially for someone who’s into technical BMX riding.

The Path Pro tires hold their line well on street and park, and the sealed hubs give you that buttery, smooth roll.

Plus, the whole build just feels solid.

You can ride hard without second-guessing your setup.

And that’s what matters most, because all you want to think about is that next super-creative combo, not parts on your bike.

5. Real Rider Feedback

• Jeremy B.: “Super impressed with the feel and strength of the EX. Easily the best complete I’ve owned in years.”
• Leo S.: “Erik Elstran’s bike had to be unique – and this one doesn’t disappoint. The wave tube is a nice touch.”
• Sam M.: “Rode this straight out of the box at the park. Everything felt tight and responsive. Geometry is spot on.”
• Chris D.: “Love that this bike feels like a true street setup. The C5 hub has been buttery smooth so far.”

6. Potential Downsides Of The Sunday EX Bike

• No Pegs Included: You’ll need to grab a set if grinding is your thing.
• Only One TT Size: Riders shorter than 5’6” may want a shorter frame. (Luckily, you can check out Julian Arteaga’s signature EX bike, which comes at a 20.75″ top tube length.)
• It surprises me that Erik Elstran’s signature bike doesn’t come with a freecoaster – only because he rides a freecoaster.

Conclusion: Is The Sunday EX The Right Choice For You?

If you’re looking for a complete bike that’s truly ready to shred straight out of the box – the Sunday EX (Erik Elstran) is a no-brainer.

It has a pro-level frame, modern geometry, and dialed parts.

From the chromoly everything to the sealed hubs and aftermarket tires – this isn’t some cookie-cutter beginner bike.

It’s made for riders who push themselves and want gear that can keep up.

Whether you’re hitting ledges, manuals, rails, or mixing in some park, this bike can do it all.

And if you’re a fan of Erik Elstran, you’ll feel right at home riding his signature whip.

Sure, it might not have the exact parts that Erik rides, but for under $700, this bike truly delivers.

Ready to ride like Erik? The EX is waiting for you.
