The Maddog Gen IV 50cc (PMZ50-21) is the middle generation. It keeps the Ruckus-inspired tubular frame and the same 49.5cc air-cooled four-stroke engine that have powered every Maddog 50cc, then adds refreshed lighting and updated dash details over the Gen I. If you want a Maddog that looks newer than the original but costs less than the Gen V, this is the one.
Three reasons riders pick the Gen IV:
Middle of the lineup pricing. The Gen IV slots between the original Gen I and the current Gen V. You pay less than the Gen V while getting the lighting and dash refresh over the Gen I.
Same proven engine. The 49.5cc single-cylinder four-stroke and automatic CVT transmission carry over unchanged from Gen I. Same dependable powertrain, same moped classification benefits, same easy maintenance.
Same customization platform. Frame mounts and accessory points line up with both the Gen I and Gen V. Aftermarket exhausts, seats, mirrors, and bodywork made for the other generations fit the Gen IV.
Who it fits
Riders who want a refresh on the original Maddog without paying for the Gen V's full LED setup and digital dash. Commuters in moped-eligible states who want updated styling at a mid-tier price. Builders who plan to swap parts anyway and want a mid-generation base to start from.
Frequently Asked Questions
Do I need a motorcycle license to ride the Maddog Gen IV 50cc?
It depends on your state. Most states classify a 49.5cc moped as a vehicle that requires only a regular driver's license, not a motorcycle endorsement. A few states require a moped permit. Check your local DMV before you buy.
What kind of gas does it take?
Regular 87-octane unleaded pump gas.
What's the fuel economy?
Riders report around 90 to 110 mpg in normal use. Your number depends on how aggressive you ride.
Does it come fully assembled?
The Maddog Gen IV ships in a crate roughly 85% assembled. Final setup includes mirrors, fluid fills, and a pre-delivery inspection. Most authorized dealers handle setup for you. If you buy direct, plan on 2 to 3 hours of assembly.
Why pick the Gen IV over the Gen I or Gen V?
The Gen IV gives you the lighting and dash refresh over the original Gen I without the price step up to the Gen V's full LED lighting and digital dash. It's the middle option in the lineup.
What's the difference between Gen I, Gen IV, and Gen V?
The engine, frame, and CVT transmission are the same across all three generations in the 50cc class. Gen I has the original styling with a halogen headlight and analog speedometer. Gen IV added refreshed lighting and updated dash details. Gen V is the latest version with full LED lighting and a digital dash.
Can I customize it?
Yes. The Maddog frame supports a wide range of aftermarket parts including exhausts, mirrors, seats, lights, and body panels. Parts that fit Gen I and Gen V Maddogs in the same cc class generally fit Gen IV.
Where do I get service or replacement parts?
Visit our Parts page or contact an authorized Icebear dealer in your area. We publish service manuals on the Service Manuals page of this website.
Is it street legal?
The Maddog Gen IV is street legal in most US states under moped registration. A few states require motorcycle registration for any motorized two-wheeler. Check your state's rules before you ride on public roads.
Is it good for beginners?
Yes. The automatic CVT transmission removes the learning curve of clutch and gear control. New riders should still take a basic safety course before riding on public roads.
Will my bike look exactly like the photos?
Some parts may vary slightly from the photos depending on production batch. The engine, frame layout, and core specs stay the same.
