The fun doesn't stop
They're going to dump it — every kid does. That's usually the moment the fun stops and something goes back in the garage. Not this time. They pick it up, dust off, and ride harder. The afternoon keeps going.
Make it yours
A year from now, yours won't look like anyone else's — new bars, new sprockets, a Predator 212 when you're ready. Same frame, plus a community that's already tried every mod you're thinking about. It grows up about as fast as they do.
Beats another screen-time fight
You've had that argument enough times. This one ends differently — nobody has to be talked into going outside. No battery to charge, no excuses, they're just out the door. And honestly? You'll want a turn too.
2026 Upgraded
Meet the New GMB100
We didn't chase a bigger number. We made the fun last longer — better tires, tougher rims, grips that don't quit.

GMB100 Frequently Asked Questions
How fast does the FRP GMB100 99cc mini bike go?
The stock GMB100 has a maximum speed of 24 mph. Actual speed varies with rider weight, terrain, weather, maintenance, and riding conditions. GMB100 99cc top speed guide.
GMB100 or GMB100P — which one should I get?
Pick by terrain, not by price. Both use the same 99cc 4-stroke engine; the GMB100 carries up to 220 lb, while the GMB100P's manual lists 165 lb. The GMB100 is the flat-ground bike: rigid frame, 24 mph, 79.5 lb — enough for a yard, a farm lane or packed dirt.

Is the GMB100 a 100cc mini bike?
Yes — the GMB100 runs a 99cc-class engine, the same size class most riders search as a 100cc mini bike. It delivers exactly what 100cc shoppers expect: 24 mph top speed, a 220 lb rider capacity, and a pull-start 4-stroke that runs on regular pump gas with no oil mixing.
What oil does the GMB100 take, and does it come with oil?
Use SAE 10W-40 4-stroke motor oil. The oil capacity is 0.35 L, and the bike ships without engine oil, so add oil before the first start. Gas and oil are added separately; do not premix them. GMB100 oil and first-start guide.
Is the FRP GMB100 street legal?
The stock GMB100 is sold for off-road recreational use and should not be assumed street legal. Registration and riding rules vary by state and locality, so check the rules where you live before riding anywhere other than permitted private property or off-road areas. mini bike street-legal guide.
Can adults ride the GMB100, and what is the weight limit?

Can I install a Predator 212 engine on a GMB100?
A Predator 212 swap is an aftermarket modification, not part of the stock GMB100 configuration. It can require changes to engine mounting, clutch and chain alignment, braking, and other safety components, and it may affect warranty or compliance. This is a project for experienced builders.

What is the GMB100 return window?
The GMB100 has a 75-day return window. FRP provides a free return shipping label for approved returns. FRP GMB100 75-day return policy.
