GMB100 Frame
No. This is a frame-only kit. You supply your own engine.
GMB100 Upgraded Frame, hydraulic brake system (pre-installed), universal engine mounting plate, tool kit, and user manual.
To complete your mini bike build you will typically need an engine, clutch, chain and sprocket, and basic tools for setup and adjustment. The exact parts may vary depending on the engine and drivetrain setup you choose.
Yes. The GMB100 frame is compatible with a Predator 212 engine, making it one of the most popular engine choices for this build.
Bolt-on compatible with horizontal-shaft engines from 79cc to 225cc, including the Predator 212, Honda GX160 / GX200, Tillotson 212, and most Honda GX-series clones with a standard 3/4" shaft.
No. The frame uses a universal engine mounting plate and is designed for bolt-on installation.
You can, but this is a general-purpose platform built around a 13-inch wheel. If the build is specifically straight-line drag, the RMB Rebel is the purpose-built option — a 90% complete roller with a 43.4 in stretched wheelbase, a narrow-front / wide-rear stance and a semi-slick rear already fitted. Not sure which format you need? See the roller frame build checklist.
Private property only. Custom-built mini bikes are not street legal and not intended for public roads or OHV parks without proper registration.
Yes. The frame contains no gas-related components, so it ships freely to California.
No, we currently only ship within the United States.
Ships within 1–2 business days. Delivery takes 3–7 business days within the continental US.

Just a really nice little machine. Better than expected. Still in the build process, but coming along nicely. No complaints so far! 🙂🙂

Already threw a 224 predator on this bad boy and it went together like a charm! I was ripping and riding in no time. Now time to start rebuilding the engine with performance parts and she what she can really do! Getting this roller frame has been a great purchase!

this frame is super sick right out of the box, if you’re looking for a mini bike definitely look into FRP they have everything you’ll need. mine is 212 swapped and it runs amazing threw a nibbi carb on it and this thing shreds.

Bike seems solid. The handlebars didn't loop through like the video shows you.. I had to unbolt the throttle and be brakes off handlebars and reinstall. I also snapped the metal piece holding down handle bars but the customer service quickly responded and are sending me a replacement so satisfied customer overall.

The chassis is well-built and supports my engine perfectly.
easy setup
Paint job is decent. Didn't show up scratched or chipped, which is rare
The throttle cable came with the ball end broke off and it took a while for the replacement to get shipped but otherwise solid bike frame.

The GMB 100 is the best Minibike in the whole world.. I currently have four of them and would like to build a fifth one with the frame kit and a 212 motor. I think it’s going to be my winter time project. !!

Really good frame and such but the mounting plate has bad instructions
FRP Moto GMB100 Mini Bike Frame | Predator 212 Compatible | 99cc–212cc Custom Build
Honestly way better than I expected. Frame feels solid and heavy, not flimsy at all
Bolted a Predator 212 straight on. No mods, no drama.
Welds look clean and strong
Brake setup is legit. Big step up from the cheap cable brakes I'm used to.
Paint job is decent. Didn't show up scratched or chipped, which is rare
Glad we went with the upgraded frame. Feels way more planted and handles better. Total game changer!
Frame feels sturdy. Minor setup needed out of the box but runs great now. Kids enjoy it a lot.
I'm about 210 lbs and it holds me just fine. Feels stable riding it.
good frame for adults
is the real deal. Tough, stable, and handles abuse like a champ. Highly recommend!
Rides smooth and feels planted, even when you open it up a bit.
Much better handling than standard mini bikes we've tried.
Feels like it'll last for years!
The difference from the standard frame is night and day.
The extra rigidity really shows when cornering.
The welds and construction look professional.
The stability improvement over our old bike is huge.
