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

Give a 5-to-10-year-old their first throttle bike at a survivable speed.
Keep rides to 15 miles or less on the integrated battery.
Swap four sets of colored decals that Rambo includes.

Terrain: Backyard and private land.

A 17 mph ceiling on 20-inch wheels is the whole point: it rides like a fast kid's bike, not like a motorcycle. Still a throttle machine that needs an adult watching.

Not for

Public roads or paths without reading Utah's age rules: under-8 riders may not use the motor in public at all, and 8-to-13-year-olds need direct supervision.
Riders over the 120 lb limit.
Anyone expecting pedal assist: the page describes throttle power only.

Experience: Beginner.

What we still don't know.

Bike weight, seat height, wheelbase, ground clearance, and charge time: Rambo publishes none of them.
Whether a helmet sized for a 5-year-old meets the DOT standard Utah requires off-road; buy one that does.

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 page advertises "a 250w hub driven motor" with a top speed "around 17mph" and a 24 V, 10.5 Ah battery integrated into the frame. The body text says "Weight Limit: 120lbs." Mechanical disc brakes with a motor cutoff. A battery-upgrade picker elsewhere on the page says 10 Ah (24 V); we record the 10.5 Ah of the bike's own description. Rambo publishes no bike weight, 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 Yes

Classes offered 2 (as sold: a 250 W throttle bike at about 17 mph; Rambo publishes no class setting)

Throttle Yes

Registration if it qualifies None

The manufacturer says

Rambo says "The 250w hub driven motor delivers throttle-controlled power on demand," recommends ages 5-10, and lists a 120 lb weight limit.

What Utah law says

Yes, on Rambo's own numbers. A 250 W motor at about 17 mph with a throttle sits inside the Class 2 limits of 750 W and 20 mph. Rambo states no class setting, so this is the maker's figures rather than a certification.

If it doesn't qualify

If it were later modified past 750 W or past 20 mph on the throttle, Utah would treat it as a "high power electric device," and riders under 16 could not operate it on any road. As sold, nothing on the page suggests it can be.

Legal e-bike does not mean legal rider. Utah's e-bike age rules (41-6a-1115.5) bar under-8 riders from using the motor in public and require direct supervision through age 13. See For parents.
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.
