2021 Sunday Ex Review

4.0 rating

The 2021 Sunday EX bike has two options. Choose between the matte trans red Erik Elstran Signature with a 20.75″ top tube. Or the 21″ Matte Raw Jullian Ortega signature. Both options have some aftermarket parts, but they aren’t the best bikes.

Highlights

  • ✅ – Full Chromoly
  • ⛔️ – Under $500
  • ⛔️ – Double Wall Rims (Rear is a double wall)
  • ⛔️ – Pegs
  • ✅ – Fully Sealed Bearings
  • ✅ – 3 pc. Cranks
  • ✅ – Freecoaster – (Erik Elstran Version has a cassette) – What is a freecoaster?
  • ✅ – Brakes
  • ✅ – Gyro tabs

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

Buy if you are learning:

  • 180
  • 360
  • bar spin
  • grinding rails
  • fakie tricks

Don’t buy if you are learning:

  • big drops
  • tail whips
  • 540

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
