Fit

Who it fits, and what it's for

Fit is about use and body, not quality. A bike that fits can still be too much machine, so read the experience note before the spec table.

It's for

Ride public land where a 750 W motor keeps the argument simple.
Haul gear on the standard extra-large rear rack.
Own the cheapest mid-drive in the line with a real drivetrain.

Terrain: Forest roads, Backyard and private land.

750 W nominal and a 28 mph claim put it in Class 3 territory when pedaling, and the page also sells throttle-only range. A beginner can grow into it in a low mode; the top of its range is not beginner ground.

Not for

Riders who need a confirmed legal e-bike without checking modes. Read the legal section first.
Technical climbs: mid-drive torque is unstated, and 24-inch wheels roll over less than 26s.
Riders or cargo over the 300 lb capacity.

Experience: Beginner to Experienced.

What we still don't know.

Motor torque, seat height, wheelbase, ground clearance, and charge time: Rambo publishes none of them.
What the ACS switch selects per mode, and whether the throttle is capped at 20 mph in any of them.
We have not set a rider-height band. Sit on one before buying.

Specs

The numbers, and where each one comes from

Manufacturer figures are claims, not measurements. The source label on every row says which is which. An unknown value stays unknown.

Spec	Value	Source
Model number	Unknown	Unknown
Peak power	1.0 kW	Manufacturer
Rated power	0.75 kW	Manufacturer
Motor torque	Unknown	Unknown
Battery voltage	48 V	Manufacturer
Battery capacity	15 Ah	Manufacturer
Battery energy	0.72 kWh	Calculated

Seat height	Unknown	Unknown

Top speed	28 mph	Manufacturer
Range	48 mi	Manufacturer
Front wheel	24 in	Manufacturer
Rear wheel	24 in	Manufacturer
Ground clearance	Unknown	Unknown
Wheelbase	Unknown	Unknown
Charge time	Unknown	Unknown

All figures are manufacturer claims from the Rambo product page, checked November 7, 2026. We have not seen or ridden this bike. The Performance row reads "Total nominal output 750W. 1,000W peak rating." Weight is with the battery removed; the 15 Ah pack adds 9 lb and the 20 Ah adds 12. Range is 48 miles on the 15 Ah battery and 65 on the 20 Ah. The spec table says an 8-speed Box derailleur while the overview says Shimano 8-speed; we record neither as authoritative. Rambo publishes no torque figure, seat height, wheelbase, ground clearance, or charge time.

Utah

Is it an e-bike in Utah?

An e-bike needs no title or registration in Utah, but only if it meets the state's definition. What the manufacturer says, what the statute says, and what happens if it doesn't qualify.

Utah e-bike as sold Unclear

Classes offered 1, 2, or 3, switchable

Throttle Yes

Registration if it qualifies None

The manufacturer says

Rambo's Performance row reads "Total nominal output 750W. 1,000W peak rating," and the overview calls it a "public-land-friendly 750W Bafang motor" whose ACS display "lets you switch between Class 1, 2, or 3 modes."

What Utah law says

Unclear, but the closest of the adult Rambos to qualifying. The 750 W nominal rating sits at Utah's cap rather than past it, and a peak claim is not continuous power. What keeps it unclear is the same pattern as our Bakcou entries: a 28 mph claim with no mode split, throttle riding the page itself mentions, and an ACS switch nobody has shown us per mode.

If it doesn't qualify

If it doesn't qualify, Utah counts it as an electric motorcycle: a title and OHV registration for public trails, like an e-moto. An e-bike set past the maker's original speed or power settings is a "high power electric device" under the same statute, with its own age and road limits.

Wherever you ride it, stay in a Class 1 or 2 mode and keep the receipt showing the factory settings.
Warranty is a lifetime frame warranty for the original purchaser and one year on everything else; register the serial number within 30 days, per Rambo's warranty page.

Check the bike, not the label. Utah's limits are 750 watts, 28 mph with pedal assist, and 20 mph on the throttle alone. For how to tell, read E-bike or not. For age limits by class, see For parents.
