2019 Fly Proton Freecoaster Price
Fly made a really good bike for a little over $500. For $550 you can get a bike with everything that you need. This is a great price for the value.
2019 Fly Proton Freecoaster Quality
The proton is a high-quality BMX bike. There is not much on here that would be considered low quality. Here is what’s killer on the bike.
Double Wall Rims. Double wall rims hold up to bigger tricks in the park and the streets.
Good 3pc. Cranks. 48 spline 3pc cranks are the best option possible.
Highlights
Very good value
The price is right. For $550 you get great quality. Not many bikes are able to provide this level of value for this price. It’s great.
Lowlights
No Hub Guards
I think it is crazy that they include 4 pegs on this bike, but no hub guards. Buying a set of hub guards for the Proton would cost around $80 depending on which ones you get.
Buy if you are learning:
- Bars
- x-up rides
- 360
- Flowing trails
- Stair drops
- tailwhips
Don’t buy if you are learning:
- Solid for any kind of trick
