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

Fold it into a car trunk or RV storage and unfold it at the trailhead.
Ride gravel roads and field edges on 20 x 3.3 tires.
Adjust the stem height for different riders, per Rambo's product card.

Terrain: Streets, Forest roads, Backyard and private land.

750 W nominal is the gentlest motor in the line, but the page still claims 30 mph and a removable thumb throttle. Intermediate rider at minimum.

Not for

Singletrack: small wheels, 62 lb, and no published suspension spec.
Riders over 300 lb of rider and gear.
Anyone who needs a confirmed Utah e-bike in its delivered form. Read the legal section first.

Experience: Intermediate to Experienced.

What we still don't know.

Seat height, wheelbase, ground clearance, and charge time: Rambo publishes none 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.

Rated power	0.75 kW	Manufacturer

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 "Peak Rating 1000W, 80nm of Torque, nominal power of 750W." The battery is "48V 10.4AH 18650 cells equaling 500 watt hours" (48 x 10.4 is 499.2 Wh; we calculate). Weight is with the battery removed; the pack adds 8 lb. Wheels are Kenda 20 x 3.3. 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 1, 2, or 3, switchable

Throttle Yes

Registration if it qualifies None

The manufacturer says

Rambo's Performance row reads "Peak Rating 1000W, 80nm of Torque, nominal power of 750W," and the display's "Adjustable Class Setting (ACS) lets you switch between Class 1, 2, or 3 modes."

What Utah law says

Unclear. The 750 W nominal rating is exactly at Utah's cap, not past it, and a peak claim does not count as continuous power. What keeps it unclear is speed: the page advertises 30 mph without saying which mode, which is past the 28 mph Class 3 pedal-assist ceiling if that is pedal assist, and past the 20 mph throttle limit if that is the throttle. Utah allows a programmable e-bike that meets each class in each mode; nobody has shown us what this one does 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.
