That site I linked is the best (and only?) place to get a Scrambler. I don't think stores will carry it; EighthInch is the fixed gear brand of a Wisconsin bike store called Wheel & Sprocket.

And yes, you can add brakes. I will try to explain the parts to you...


Frame Color / Size: You need to figure out what size frame you should get.
Wheel Color / Style: You would get machined sidewalls cause you are getting brakes.
Bar Style / Color / Size: Do you know the difference between bullhorns/drops/risers? 40 or 42 cm refers to the bar width.
- Alloy Bar-End Upgrade: You don't need this.
Seatpost Color: Self-explanatory.
Crankset Color/Length: You also need to figure out crankset length... bah idk how to explain this...
Pedal Style/Color: "Track" pedals or plastic BMX style pedals I'm guessing.
Chain Color: Self-explanatory.
- Half-Link Chain Upgrade: You don't need this.
Saddle Color: Self-explanatory.
Tire Color: Self-explanatory.
Track/Bullhorn Bar Grip : What color tape do you want on your bars?
Straight/Riser Oury Grip: If you get riser bars, what color grips do you want?
Freewheel: Choose this if you want to ride single speed (you can coast).
Fixed Cog Size: Choose this if you want to ride fixed; would also need to figure out an ideal gear ratio.
- Julian Wheel Upgrade: Basically if you want really deep rims... to look cooler...?
- Fyxation Session Tire Upgrade: Intense colorful tires... not necessary either but if you want to look cool.
- Freestyle Bar Upgrade (must be paired with freestyle stem): For doing tricks, i.e. unnecessary.
- Freestyle Stem Upgrade (must be paired with freestyle bar): For doing tricks, i.e. unnecessary.
- Freestyle Cranks Upgrade: For doing tricks, i.e. unnecessary.
- Splined Chainring Choice for Crank Upgrade: Unnecessary.
- Double Toe Clips and Straps Upgrade: Only need these if you are riding fixed, and unnecessary for single speed.
- Headtube Extender Upgrade : Unnecessary.
- KNOG Beetle Lightset Upgrade: These are little blinky lights, might as well add them if you are going to buy them eventually anyway.
- Bolt-On Bash Guard $10 (must be paired with splined chainring): Unnecessary.
- Sealed Headset Upgrade $50: Unnecessary.
- 15mm Socket / Bottle Opener Tool $10: Unnecessary.

I don't even know if that will help. But anyway the most important things you need to figure out are...

1. Are you going to ride single speed or fixed?
2. Crank length?
3. If fixed, what sized cog?

I think everything else is just a matter of picking colors.
