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
Keep moving through mud and snow by driving both wheels.
Toggle front, rear, or all-wheel drive from the thumb throttle controls.
Carry up to 300 lb of rider and gear.
Terrain: Forest roads, Backyard and private land.
Two 1,000 W motors and a claimed 32 mph. Rambo gives no per-mode speed breakdown; treat the whole bike as beyond a beginner.
Not for
Anyone who needs to know it is a legal e-bike in Utah. Read the legal section first.
Riders under 16 even in a Class mode, if it is set past the maker's settings; Utah's high power electric device rules bite.
Lifting onto a car rack: 79 lb without the battery.
Experience: Intermediate to Experienced.

What we still don't know.
Seat height, wheelbase, ground clearance, and charge time: Rambo publishes none of them.
Whether the bike limits output in a Class mode, and what the ACS switch actually selects.
We have not set a rider-height band. Sit on one before buying.

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 "2,500w peak rating, 180Nm of torque, 2,000w nominal power" for the pair of 1,000 W hub motors. The battery is internal and dual-battery capable; range is up to 65 miles on the single 20 Ah pack and Rambo says 65-110 with a second battery, or 95-140 on the 30 Ah upgrade. Weight is with the battery removed; the pack adds 11 lb. 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 soldNo
Classes offeredSwitchable; the page names an Adjustable Class System (ACS) without listing the classes
ThrottleYes
Registration if it qualifiesNone
The manufacturer says
Rambo's Performance row reads "2,500w peak rating, 180Nm of torque, 2,000w nominal power," and the page says the dual 1000w hub motors provide "a total output of up to 2000W."
What Utah law says
No, on Rambo's own page: 2,000 W nominal across the two motors is far past Utah's 750 W continuous cap, and the page advertises 32 mph on a thumb throttle.
If it doesn't qualify
It doesn't qualify as sold, so Utah treats it as an electric motorcycle: a title and off-road OHV registration for public trails, like our Drax Apex.
Utah's statute says "an electric motor" of no more than 750 W and never says how two motors count; it does not matter here, because Rambo itself publishes 2,000 W nominal for the bike as a whole.
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.
