One of the best builds yet!

This thing rides smooth, pulls a music trailer with ease. And the color choice…pure beauty.

Blue Quad

This is my 3rd SE I'm more than pleased with this bike, it has everything I was looking for. It's better than Big Ripper and here's why -Hydro brakes, proper fat cranks, fat tires. Most unique frame of all the SE bikes. Blue and chrome go well together, bike comes great stock, I've only upgraded to flangeless grips, polished bear trap pedals and polished pegs. Waiting for Profile Elite cassette hub. Perfect wheelie bike.


This is my first wheelie bike and it is so worth it hard to pop up when you first get it but you get used to it so far and you will be wheeling it with in 3 days


THIS BIKE IS CRAZY!!! I'm 5 foot, 13 years old and I can wheelie this perfectly. Anyone over 5 foot should look into this bike. I have the Blue 2021 model and I can say so myself it looks better in person than in pictures for sure.

Love The Bike

This bike is one of the best I've ridden in my entire life. For people comparing heights I'm about 5'10 and ride the bike comfortably with the seat slightly raised. I've seen people as tall as 6'4 ride this bike comfortably and people as short as 5'3-5'4 can ride it just fine. The fat tires and disk brakes make the bike perfect for wheelies. The brakes are okay in the beginning but as you use them they become noticeably better and I am very pleased with them. The color is beautiful in person. It is a deeper royal blue than what is shown in most pictures. The chrome is very high polished and makes the bike pop. The blue paint has a gloss finish and when polished looks phenomenal. The bike is great and I look forward to using it for a long time. 10/10 bike by SE!
