Can you tell what's legal?
Look at the bike. Guess what it is in Utah: a legal e-bike that needs no title, an electric motorcycle that needs a title and OHV registration, or unclear even to us. Then check the maker's own numbers. Most people get fooled, because looks lie and spec sheets don't.
Utah's line, in brief. Under Utah Code 41-6a-102, a legal e-bike must have fully operable pedals and a motor of no more than 750 W. Class 1 is pedal assist to 20 mph, Class 2 is a throttle to 20 mph, and Class 3 is pedal assist to 28 mph with a speedometer. A bike advertised or modifiable past those numbers in any mode is excluded, even if you ride it in a legal mode. Everything past the line is an electric motorcycle: title and OHV registration for public trails, and no street riding as delivered. See E-bike or not and the statute.
Why this quiz exists. Moped-style bikes with pedals and a Class switch are the easiest to misread. Wired advertises its Predator at 8,000 W peak — a 2,000 W nominal rear motor and a 1,500 W nominal front motor — and 55+ mph unrestricted, shipping as Class 2 by default but adjustable to Class 1, Class 3, or Unrestricted via the display (Wired Predator). Ariel Rider splits its line the same way: its street models ship as Class 2, while its PPB line (Grizzly and MUDD 72V, 8,000 W peak) is labeled private property only and not street legal (Ariel Rider). Pedals and a switch don't cure numbers past Utah's caps. Below, every bike is one we documented, with the maker's page and the Utah verdict side by side.

2026 Rambo Dominator HD · E-bike · Manufacturer specs only · Full specs, fit, and sources
The maker says: Rambo's Performance row reads "1,632 peak rating, 160Nm of torque, 1000w nominal power," and the display "Includes Adjustable Class Setting (ACS) which allows users to select different "classes" of operation. Easily switch between class 1, 2 or 3."
What Utah law says: No, on Rambo's own page. Utah's definition caps a qualifying e-bike at 750 W, and Rambo advertises 1,000 W nominal and a 1,632 W peak on the product page itself. The ACS switch does not cure that: the statute excludes a bike that is advertised past the limit, whatever mode it is riding in.
What gives it away: Rambo's own Performance row advertises 1,000 W nominal and a 1,632 W peak, plus 32 mph. Utah caps a qualifying e-bike at 750 W continuous, and excludes a bike advertised past that in any mode. The Class switch doesn't cure advertised power.

2026 Rambo Kid's 24" Chameleon · E-bike · Manufacturer specs only · Full specs, fit, and sources
The maker 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.
What gives it away: Rambo advertises a 250 W motor and 16 to 17 mph. That sits inside the Class 2 limits of 750 W and 20 mph on the throttle. Small and dirt-bike-shaped doesn't mean electric motorcycle.

2026 Yozma IN 10 · Off-road e-moto · Manufacturer specs only · Full specs, fit, and sources
The maker says: The order page requires each buyer to confirm they are 14 or older and states the vehicle "is intended for off-road use only and is not permitted on public roads."
What Utah law says: We have not tried to register this model. Utah's OHV registration system did title X-Pro's off-road-only Drax Apex, but that is a different maker and tells us nothing certain about Yozma.
What gives it away: Yozma advertises a 2.6 kW peak motor and 28 to 40 mph across its modes. The file notes the pedals may or may not drive the wheel; either way, thousands of watts is far past the 750 W e-bike cap, so it is treated as an off-highway vehicle.

2026 Bakcou Flatlander SD · E-bike · Manufacturer specs only · Full specs, fit, and sources
The maker says: Bakcou says the Flatlander SD uses a hub motor "rated at 750 W nominal" and lists "ODP - Comprehensive 'On-Demand Program' for all classification selections."
What Utah law says: Unclear, but the closest of the Bakcou e-bikes. A 750 W rated motor is inside Utah's limit, and Utah allows a programmable e-bike that meets each class in each mode. What keeps it unclear is the same ODP system: Bakcou's Mule SD page says it can be set to unlimited, and Utah excludes a bike modifiable past 20 mph on the throttle.
What gives it away: The 750 W rating is exactly at Utah's cap, and Utah allows a programmable e-bike that meets each class in each mode. What keeps it unclear is the same system on Bakcou's Mule SD page, which can be set to unlimited: Utah excludes a bike modifiable past 20 mph on the throttle.

2026 Rambo Kid's 20" Trailbreaker 3.0 · E-bike · Manufacturer specs only · Full specs, fit, and sources
The maker 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.
What gives it away: Rambo advertises a 250 W hub motor at about 17 mph. That is inside the Class 2 limits of 750 W and 20 mph on the throttle. Like its 24-inch sibling, it looks like a dirt bike and is a legal e-bike on the maker's numbers.

2026 X-Pro Drax Apex · Off-road e-moto · Owned and registered by us · Full specs, fit, and sources
The maker says: XProUSA lists the bike as off-road use only and says it cannot be officially registered for any purpose.
What Utah law says: Utah issued a title and OHV registration in November 2026. That is off-road registration, not a street plate.
What gives it away: X-Pro advertises 10 kW peak, 6 kW rated, and 55 mph. Utah titled and OHV-registered ours in November 2026 despite the maker's off-road-only claim. That title is off-road registration, not a street plate, and the bike is not street-legal as delivered.

2026 Rambo Ranger Folding · E-bike · Manufacturer specs only · Full specs, fit, and sources
The maker 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.

2026 Bakcou Puma X22 SD · Street-legal capable · Manufacturer specs only · Full specs, fit, and sources
The maker says: Bakcou says it "will provide the consumer with a Manufacturer's Certificate of Origin (MCO) at the time of purchase," that the MCO allows "you to register your bike for street or trail use where permitted," and that "consumers are solely responsible for the registration" of the bike.
What Utah law says: We have not seen this bike or tried to register one. The MCO is a manufacturer claim; we haven't seen one. With an MCO in hand, you may not need the TC-569A ownership statement that our Drax Apex needed.
What gives it away: Bakcou advertises 22 kW peak, 6 kW rated, and 70+ mph in its top mode, with an MCO the maker says allows street or trail registration where permitted. Street-legal capable still means title, plate, inspection, insurance, and a license. It is not the no-title e-bike path; it is an e-moto with equipment.

What to do with your score
If looks fooled you, that's the point. Utah doesn't classify by paint, fat tires, or pedals in the box. It classifies by watts, miles per hour, and whether the pedals are fully operable. Check the spec sheet and the statute before you buy, register, or let a kid ride.
Every bike above is documented with sources on its own page. We didn't invent verdicts for this quiz: each answer comes straight from data/bikes.yml, and the build fails if the two disagree. If a maker's page changes, the bike page and this quiz are checked together. How we document: methodology.
