What makes the GMB100U different from the base GMB100?

The GMB100U features a vintage minimalist frame design with a large-letter fender, an optional LED headlight, and a built-in cargo rack system. It is designed for riders who want a functional, utility-oriented mini bike rather than the stripped-down sport look of the base GMB100. The GMB100U and base GMB100 are both rated at 24 mph; the GMB100U supports 185 lbs while the base GMB100 supports 220 lbs.

What is the top speed of the GMB100U?

24 mph on flat ground with a 150 lb rider. The GMB100U uses the same 99cc 4-stroke engine tuned for torque and utility use rather than top speed.

How much weight can the GMB100U support?

Up to 185 lbs rider weight. This is the rated capacity. Heavier riders should consider the base GMB100 or the GMB100P (both rated 220 lbs).

What are the cargo rack options for the GMB100U?

The GMB100U is available in three configurations: with Front Cargo Rack only ($399.99), with Rear Tow Bar only ($409.99), or with both Front Cargo Rack and Rear Tow Bar ($419.99). All configurations include the same 99cc engine and vintage frame.

Is the GMB100U street legal?

No. Like all FRP mini bikes, the GMB100U is EPA-certified for off-road use only: private property, backyard trails, campgrounds, and off-road parks. Not available in California.

Does the GMB100U support a Predator 212 engine swap?

The GMB100U frame is not optimized for the 212 swap in the same way as the base GMB100 frame. If a 212cc upgrade path is important to you, the base GMB100 or GMB100P is recommended.

What does 85% pre-assembled mean?

The bike arrives with most assembly done at the factory. You attach the handlebar, front fork, front wheel, and front fender, typically under 1 hour with basic tools.

What is the shipping cost?

Flat-rate $119.99 FedEx shipping to all 48 contiguous US states. Orders ship within 1-3 business days.

Customer video review of FRP Moto GMB100U 99cc Utility Gas Mini Bike with Cargo Rack & Tow Bar

We have other smaller FRP bikes. My son wanted an upgrade, so we got him this one and he loves it. I was really impressed with the customer service. I had just moved, and accidentally given them the wrong ZIP. Customer service was extremely tentative and made corrections with FedEx and got my order to me quicker than expected!
