Overview
BRAKE INCLUDED (no pictured)
With the addition of the new Trebol Mini Lever, Trebol Mini Stem and the new fork design with an integrated cone shape design, the 18” Supernova is more dialed than we could have imagined!
This bike features a 100% chromoly frame, fork & bars, fully sealed hubs, Trebol Bueno 152mm cranks, Ruben 135mm grips, and Fuego 18” tires. This bike is scaled down to ride just like our 20” bikes.
The Supernova is designed for the little shredders out there that need a bike that can hold up to a higher level of riding but are not quite ready for a full-size bike
The 2021 Supernova is available in Gloss Orange with Flat Black parts, and Gloss Black with Flat Black parts and Polished hubs.

Frame Geometry
A: Top Tube Length: 17.5″ – Learn what size is right for you here.
Good for smaller riders who need a bike with amazing quality!
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: 11.6″ – Learn About Chain Stays Here
This is a short chainstay.
A short chainstay gives the bike a responsive feeling. This is important for smaller riders to learn tricks.
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: 10.5″
F: Stand over height: 8″
This is a medium standover.
A medium standover provides a good balance between control and responsivness.

G: Rise: 8″
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: 26″
This is a medium width.
Narrow bars make barspins easier.
Wide bars give you more control and stability when steering.
I: Backsweep: 10º
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: 2º
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.
Price
This bike is pretty expensive at $540. But it is one of the best 18″ bikes on the market. And all things considered, I think it is a really good deal.
Quality
Most 18″ bikes are made out of junk. With unsealed bearings, aluminum parts, and single wall rims. They provide no way for a new rider to actually progress.
The supernova is different though. It has FULL CHROMOLY, double side wall rims, and sealed bearings. Even including female axles and a gyro option. You wont find anything better than this.
Buy if you are learning:
- Bunny hops
- 180
- footjam
- pull up barspins
- t-bog
- 360
- barspin
- back flip
Don’t buy if you are learning:
- Good for any trick
Conclusion
I normally stay away from 18″ reviews, just because they are all pretty much the same. However last night I was helping someone find a bike for their kid and I stumbled across the 2021 Supernova. I was completely blown away by the quality. This is important for kids that are progressing but still small. We need more of these options, but for now, it looks like Fly is the only one doing it.
