how much does it weigh?
A shopper on Sep 19, 2017
BEST ANSWER: GT is known for not posting their official weights, that said it will be about 26.5 lbs. Great simple bike though.
Does the bike come with brakes?
A shopper on Aug 5, 2017
Yep... The GT Slammer 20 will come with a single rear brake. It is: Aluminum U-Brake w/ Soft Compound Pad
im planning on getting the gold colored gt slammer2018 but i dont like the wheel color black would be better is that possible chance that i can get a pair for free when i get the bike?
kaiden on Aug 1, 2017
BEST ANSWER: Good Day Kaiden,
I am thinking you mean tires. The bike unfortunately will come as is, however this is a standard 20" BMX bike... there are a ton of tire styles and colors out there. Thanks for the question.
I am 5'9" tall and weigh around 218 lbs. Will I be able to fit on this bike?
A shopper on Jul 13, 2017
You could ride this bike, but with a Hi-Ten frame you will be close to the user ceiling. I might suggest you look at a bike with a full Chromoly frame. That will be more robust.
What is Max rider weight?
Misfit on Jul 28, 2018
The maximum recommended rider weight on the GT Slammer is about 175lbs.
I’m 6’0 130 would I be able to fit on this bike?
Peyton on Jun 15, 2018
BEST ANSWER: IT could work but it'd be a tight fit with the 20" top tube. Check out these bikes, the'd be a better fit...
Any recommendations for the correct pegs to use?
TPlums9 on Mar 16, 2018
I apologize that no one answered you... this Slammer will use a 3/8" Front and 14mm Rear peg.... fairly standard.
Does the brakes already in the bike?
A shopper on Sep 2, 2017
This bike will come with a single rear Aluminum u-brake, and it will be connected when you get the bike. The rest of the bike will be about 3/4 assembled. There is a good chance the brake will need adjusting once you get it.

A shopper on Aug 12, 2017
The brakes on this Slammer work great. They are standard Aluminum U-Brake.
