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

Start riding off pavement on the cheapest full-suspension bike we document.
Mount and dismount a low step-thru frame.
Keep maintenance to a single-speed drivetrain.

Terrain: Forest roads, Backyard and private land.

750 W nominal and a 25 mph claim. A beginner can grow into it in a low mode; the top of its range is not beginner ground.

Not for

Hill country: 60 N·m on 20-inch wheels is the softest motor in the line.
Riders who need a confirmed legal e-bike in its delivered form. Read the legal section first.
Riders or cargo over the 300 lb capacity.

Experience: Beginner to Experienced.

What we still don't know.

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.

All figures are manufacturer claims from the Rambo product page, checked November 7, 2026. We have not seen or ridden this bike. The overview says a "Rambo 750W hub-drive motor delivering up to 1,000W of peak output and 60Nm of torque"; the Performance row reads "1,000W peak rating, 60Nm of torque." Weight is with the battery (71 lb without). Range is Rambo's estimate for the 10 Ah battery. Wheels are 20 x 4.0. Rambo publishes no 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 Switchable; the display ships with an Adjustable Class Setting (ACS), classes unlisted

Throttle Yes

Registration if it qualifies None

The manufacturer says

Rambo says the Quest is "Powered by a Rambo 750W hub-drive motor delivering up to 1,000W of peak output and 60Nm of torque," with a "right-hand thumb throttle" and a display with "Adjustable Class System (ACS)."

What Utah law says

Unclear, and like the Roamer, near the line. The 750 W nominal rating is at Utah's cap, not past it; the peak claim is not continuous power. The 25 mph claim comes with no mode split, and the throttle cap per mode is unstated, so the programmable e-bike question stays open, as it does across Rambo's line.

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.
