I’ve been riding the Cult Biggie frame for over a year, so I’m excited to share my review with you.
Before I continue, I want to say this: Biggie is the best street frame I’ve ridden so far.
Yes. Really.
It is Devon Smillie’s signature frame, built for precise control, technical riding, and clean style.
With its responsive frame geometry, short chainstay length, and taller standover height, the Biggie is ready for modern street riding at the highest level.
The frame pretty much ticks all the boxes for me – especially having it available in 21.5″ and 21.8″ because you know I like larger frames.
Sure, I had a little bit of a getting-used-to-it-phase, BUT it was SO worth it. (More below.)
If you love nose manuals, quick spins, and controlled grinds, whips, etc., this frame delivers the geometry and features to make your riding tighter, snappier, and more fun.
For. Reals!
Cult Biggie Frame Review
1. Build & Design
The Biggie frame is crafted from 100% 4130 chromoly tubing, known for being strong, light, and built to take a beating.
It features top and down tube gussets for added strength up front, and an investment cast seat stay bridge and dropouts, adding both stiffness and durability.
The S-bend chainstays provide ample tire clearance, so you can run up to 2.40″ tires without any rub. But really, you can go even wider, like 2.5″ tires, and the frame will easily handle the width.
Moreover, the Biggie frame also has integrated chain tensioners in the dropouts to keep your wheel perfectly aligned.
I didn’t use them with my previous frame, but I got so used to them with the Biggie frame that I cannot live without the chain tensioners anymore. So handy.
But you’ll need a super tinny, 3mm Allen key.
Removable brake mounts and gyro tabs give you flexibility depending on your setup, allowing you to take your rear and front brake tech game to the next level.
And my favorite feature?
Taller standover height (9.65″), which gives it a clean, traditional look that also adds to the frame’s strength.
- Full 4130 chromoly tubing
- Top and downtube gussets for added front-end strength
- Investment cast dropouts and bridge
- S-bend stays for big tire clearance
- Integrated seat clamp and tensioners
The short rear end and steep head tube angle make it feel snappy, especially if you ride tech and like front-end balance. I love this geo!
Plus, the taller standover height removes some of that seat post sticking out, keeping a cleaner look, especially if you ride your seat higher.

The Biggie frame feels fast, light, and in control.
The 12.9″ rear end gives it that whippy snap you want for spins and manuals.
However, I ride it at 13.2″, which I had to get used to, coming from a frame with a 13.5″ CS length.
But the only thing that bothered me was hitting my back peg.
To resolve this, I relearned my foot-on-pedal position. It surprised me how quickly I got used to this new stance. And it was so worth it!
Right now, I don’t even notice it anymore.
Furthermore, the Biggie’s steep head tube helps lock in nose manuals or quick bar rotations much easier.
The added standover gives the bike a more classic silhouette, which I personally really like.
Additionally, the taller bottom bracket height contributes to the frame’s responsiveness and grind clearance.
This is a frame for tech riders, but it’s not overly twitchy.
The geometry feels balanced enough for heavier setups, too, and the frame stiffness really helps when you’re going hard on the streets.
Still, if you like the responsiveness but would also like a bit more stability, just go up one size.
I’m 5’11”, and I ride the Cult Biggie frame in 21.5″.

- Jake R. (21″ TT): “Best frame I’ve had yet. Nose manuals feel natural and it’s crazy strong. Love the standover height.”
- Liam T. (21″ TT): “Wasn’t sure about the steep head tube at first, but now I’m hooked. Makes switch tricks way easier to control.”
- Tina K. (20.5″ TT): “Fits big tires and still feels light. Feels strong in all the right spots. And looks clean AF in raw.”
- Chris D. (21.25″ TT): “Frame’s tough as hell. I grind every day and this thing’s holding up like a tank. Rear end feels snappy, but not sketchy.”
