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

Let a kid keep up on family rides with throttle power on demand.
Cap speed and power through the three adjustable settings until the rider earns more.
Keep weight sensible: a kid-sized frame and 180 lb capacity.

Terrain: Backyard and private land, Forest roads.

250 W and a 16-17 mph ceiling make this a real kid's machine rather than a dirt bike in disguise. Start in the lowest power setting; Rambo built the settings for exactly that.

Not for

Public roads without reading Utah's age rules first: riders under 8 may not use the motor in public at all, and 8-to-13-year-olds need direct supervision.
Riders over the 180 lb capacity, or over the 140 lb rider guidance on the product card.
Range beyond 15 miles; the integrated battery cannot be swapped mid-ride.

Experience: Beginner to Intermediate.

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 motor" with a top speed of "around 17mph" and a spec row of "Up to 16 mph"; we record the spec row. The battery is a 24 V, 10.5 Ah pack integrated into the frame (not removable). The spec table lists the bike's weight as "4 Lbs," which is plainly an error, so we leave weight unknown. One spec card says the tires are 24 x 1.95 and another says 20 x 1.95; the bike is a 24-inch model, so we record 24. The body text recommends ages 9-12 at a 180 lb limit while a product card says ages 9-14 and riders up to 140 lb; we record the 180 lb load capacity.

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 16-17 mph; Rambo publishes no class setting)

Throttle Yes

Registration if it qualifies None

The manufacturer says

Rambo says "The Chameleon has a 250w motor that has a top speed of around 17mph," with a twist throttle and "3 adjustable power settings" that "let parents manage speed and power based on their child's age and experience level."

What Utah law says

Yes, on Rambo's own numbers. The page advertises a 250 W motor and a 16-17 mph top speed, inside the Class 2 limits of 750 W and 20 mph on the throttle. Rambo states no class setting, so this is the maker's figures rather than a certification; nothing on the page suggests it can be set past them.

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.

Being a legal e-bike does not answer the age question. 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.
