Frame Geometry

A: Top Tube Length: 21″ – Learn what size is right for you here.

Check the size guide to see if its right for you..

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" – Learn About Chain Stays Here

This is a medium chainstay.

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.

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: 11.75″

F: Stand over height: 9.5"

This is a tall standover.

A tall standover makes your seat higher up and will allow you to pinch it easier when learning barspins.

G: Rise: 9.5"

Riding a tall rise, will give you more leverage on the bike. Making it easier to pull back and lift the front wheel up.

H: Width: N/A

This is a wide width.

Narrow bars make barspins easier.

Wide bars give you more control and stability when steering.

I: Backsweep: N/A

What does backsweep do?

As far as I know, there is a sweet spot for backsweep. Too much will make the bike feel weird, and too little will make the bike unstable. It seems like the sweet spot is around 11º to 12º. If you need something a little more aggressive and straight feeling, go for 10º, but only do this if 11º is uncomfortable.

J: Upsweep: N/A

This is a normal upsweep!

What does upsweep do?

There is a lot of discussion about 1º upsweep vs. 4º upsweep. Some people are running experiments and testing if the greater upsweep will make drops feel better. It seems like a lot of street riders run 4º to 5º upsweep. This helps for wrist pain and lessens the impact of big drops.


For $609 you're getting a pretty good mid-level bike. This is the same price as the 2021 Kink Cloud, the only thing missing is that it does not have any pegs. Other than that, everything on this bike is really solid and it's actually a fair price. Some companies will charge you way too much but not Stolen.


Now I really like the quality of this bike. It has full chromoly frame, forks, and bars, double-wall rims, and a handful of aftermarket Stolen and Fiction parts. These parts keep the bike riding stronger for longer so that you can progress and not have to worry about your bike breaking.

Buy if you are learning:

  • Manual
  • 180
  • Fakie tricks
  • tailwhip
  • Barspin
  • x-up
  • basic park jumps
  • 360
  • no handers

Don't buy if you are learning:

  • Good for any trick


The 2021 Stolen Sinner freecoaster version is one of stolen's most popular bikes. This is due to the price/quality ratio, which is very good. I love that you can choose between left-hand drive and right-hand drive, and the colors are pretty sick. This bike is for a mid-level rider who is trying to progress more in street riding, it can hold up to some pretty decent trick so you don't have to worry about it breaking.
