Frame Geometry

A: Top Tube Length: 20", 20.5, 20.75" and 21" - Learn what size is right for you here.

With multiple options, you can make sure that your bike is sized to fit you perfectly.

B: Chain Stay Length: 13.2” - 13.5" - Learn About Chain Stays Here

This is a longer chain stay, it will give you more balance when doing manuals and pulling up for higher bunny hops.

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: 8.75"

This is a medium/tall standover.

A medium stand over provides a good balance between responsiveness and control.

While a tall stand over allows you to pinch more of the seat for bars and t-bogs.

2021 Sunday Primer Price

I don't know man, this is kinda tough for me. I think that the primer is a little overpriced. Just due to the fact that it doesn't really have any outstanding qualities to justify the $369 price point. It's a good beginner bike, don't get me wrong, but $300-$340 would be a better price.

2021 Sunday Primer Quality

The 2021 Primer is a lower quality bike designed for brand new riders. This has hi-tensile steel. Some sealed (and some unsealed) bearings. If you ride at a mid-level this bike will not work good for you.


Multiple TT options

It is really good that the Primer comes in 4 different top tube options. A lot of completes only come in one size, and this makes people sacrifice comfort just to get a bike that they want. You should always get a bike that fits you and your style.


Hi-tensile steel/single wall rims

These are weak specs that tend to break or bend over time. If you start sending yourself down big stair sets or casing big ramps.. you will not be having fun on this bike.

Buy if you are learning:

  • 180
  • 360 taps
  • Manuals
  • pull up Barspin
  • no-handers
  • footjam

Don't buy if you are learning:

  • Freecoaster tricks
  • Grinding hand rails
  • Huge drops
  • 720
  • Flips
  • Whips
  • Big 360

2021 Sunday Primer Conclusion

For a beginner who just wants to get on a bike and test out the wonderful sport of bmx, this bike will work for you. The color options and toptube options are sick. However, it probably wont last a very long time if you decide to stick with the sport.
