Overview
With a 100% chromoly frame, fork, and bars, the 2021 EX is a bike that is difficult to match.
These bikes pushes the envelope with a tough, pro-level, Odyssey/Sunday parts package and frame design upgrades like the EX’s removable braking hardware mean business, even when your approach to riding is all about having fun.

Frame Geometry
A: Top Tube Length: 20.75″ & 21″ – Learn what size is right for you here.
This is a tall toptube.
Perfect for riders that are between 5’4″ to 6’4″
Getting a top tube that is taller than suggested will make the bike feel more controlled and less responsive
Getting a top tube size that is smaller than normal will make the bike feel a lot more snappy and responsive.
B: Chain Stay Length: 13.2” & 13.5″ – Learn About Chain Stays Here
This is a long chain stay.
This will make the bike feel controlled.
A short chain stay makes the bike feel twitchy. Spins will be easy, but airing and jumping might feel hard to control.
A long chain stay will make the bike feel really controlled. Spins will feel sluggish, but manuals and air tricks will feel nice because it will be more stable and controlled.
C: Head Tube Angle: 75° – Learn About Head Tube Angles Here
Steep head tube angles make the bike “snappy” meaning more responsive to fast turns.
A less steep head tube gives you more control.
D: Seat Tube Angle: 71°
E: Bottom Bracket Height: 11.5″
F: Stand over height: 9″
This is a tall standover.
A tall standover gives you more stability and will make bars, and t-bogs easier.
Price
For right around $500, the Sunday EX could be yours. I’m not sure how I feel about this though. Part of me says the aftermarket parts are killer and the bike is worth it. But another part of me is mad about the single-wall rims.
Quality
The 2021 Sunday EX is right in between a beginner bike and a mid-level bike. It has aftermarket parts and the full Chromoly parts. However, the single wall rims throw me off. Granted these Sunday lightning rims are better than most single-wall rims. Read more here

Conclusion
Before buying the 2021 Sunday EX, you need to ask yourself a few questions. Do you need 21″ or 20.75″? Do you want a freecoaster? Do you like raw, or trans red? Depending on how you answer these, you can figure out the best bike option for you.
This bike is perfect for someone who has a love for street riding. It has a handful of aftermarket parts that will keep it rolling for a lot longer than other stock bikes. The person who gets this bike should be riding at a mid-level.
Common Questions
- Where can I buy this bike? I am an affiliate of sourcebmx.com and always recommend them. Source is rider owned and they do so much for BMX by hosting events and sponsoring riders. Did I mention they ship ANYWHERE in the world? Buy the bike here
- Is this bike for park, dirt, or street? The Sunday EX is good for riding all 3. However, the freecoaster version has a bigger focus on street riding.
- How much does it weigh? 25.75 lbs
