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.

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

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.

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.
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

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.
