Frame Geometry

A: Top Tube Length:  20.5″ – Learn what size is right for you here.

This is a medium top tube.

Perfect for riders that are between 5’3″ to 6’

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: 13.11″ – Learn About Chain Stays Here

This is a longer chain stay. It gives you a more stable and controlled feel. It is longer than most and will feel really controlled but spins will feel sluggish

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: 75.5° – 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: 11.6″

F: Stand over height: 8.8″

This is a medium standover. 

A medium standover balances responsiveness and stability.

2021 Fit Series One (MD) Price

The 2021 Series One is priced right at $399. This is really close to the 2021 Kink gap, and is pretty close in quality. However, the 2021 Kink Whip is just a little more and is much better quality

2021 Fit Series One (MD) Quality

This is an entry-level bike with entry-level parts. I would not recommend this bike if you are an experienced rider.

Buy if you are learning:

  • Bunnyhops
  • pull up bars
  • 180
  • fakie
  • footjam
  • manual

Don’t buy if you are learning:

  • 360
  • drops
  • street tricks
  • tail whips
  • bar spins

2021 Fit Series One (MD) Conclusion

Last year, fit’s line was a little overpriced. However, it seems like they fixed that with the 2021 Series One. It is priced close to similar quality bikes. That makes me happy. Get the MD version if you are 5’3″ to 6′.

This bike is for a new rider who does not have very much experience, but want’s to try out the sport. The geometry will help a brand new rider feel confident and controlled, but the quality will not hold up to advanced riding.
