Onyx RCR 80V: 140 Miles Is the 15 mph Row

New Atlas published an Onyx RCR 80V review on 6 November 2026. The cart this desk opened the same day asks $4,599 and strikes through $5,199. Five thousand one hundred ninety-nine minus $4,599 is $600. CNET's table, dated 14 October and published 23 October, was $4,699 for the Street and $4,899 for the Dual Sport. Four thousand six hundred ninety-nine minus $4,599 is $100. The street price moved. This desk did not re-open a Dual Sport cart, so $4,899 stays an October number. The pack on the current card is 80 volts nominal, 45 amp-hours, 3,600 watt-hours, and a max voltage of 91.97. Eighty times 45 is 3,600. That is the watt-hour. Ninety-one point nine seven volts is the top of the charge, not a second battery.

140 miles is not 75 mph

The headline speed and the headline range are different rows. One hundred forty miles sits next to 15 mph. Thirty miles sits next to 75 mph. Three thousand six hundred divided by 30 is 120 watt-hours a mile. Three thousand six hundred divided by 140 is 25.7. One hundred twenty divided by 25.7 is 4.7, so the fast row spends about 4.7 times the energy per mile of the slow row, on the same 3,600 watt-hours. Do not publish 140 miles at 75 mph. The cart also says Normal, Sport, and Hyper are for off-road use only. A 15 mph eco row is not a license.

Twenty-one thousand watts is 28.2 horsepower. Twenty-four horsepower is 17.9 kilowatts. The card prints both, and they are not one motor.

21,000 watts is not 24 horsepower

The performance line on that cart reads 21,000 W and 24 hp as max power. Twenty-one thousand divided by 746 is 28.2 horsepower. Twenty-four horsepower times 746 is 17,904 watts, which is 17.9 kW. New Atlas, the same day, says the rear hub peaks at 21 kW, which it converts as 28 hp. That matches 21,000 watts. It does not match 24 hp. The card also shows 20 kW and 15 kW. CNET's October table, citing Onyx and labeled as advertised rather than measured, says 8 kW nominal. Eight, 15, 20, and 21 are four power numbers. This desk will not average them into 16. CNET also prints a claimed 0 to 30 mph in 1.7 seconds, and says that figure was not independently measured. Thirty divided by 1.7 is 17.6 mph per second. That is the claim's arithmetic, not a clock this desk held.

The pedals do not assist

New Atlas says the RCR ships with real pedals, a crank, a chain, and a sprocket, and that pedaling does not wake the motor. There is no pedal assist. The restriction wire is inside the battery compartment. Cut it, the review says, and the bike goes from a locked machine the writer calls about 20 mph to a 75 mph electric motorcycle. Seventy-five miles an hour is 120.7 km/h. The review prints 120 km/h. That is the rounding, not a second top speed. Onyx is also selling a footpeg kit so the pedals can come off. A pedal that does not assist is not the pedal in the class chart. A low-speed electric bicycle is pedals and a motor of less than 750 watts. Twenty-one thousand is not less than 750. Eight thousand, the October nominal, is not less than 750 either. The Light Bee X is the other small machine people park next to this one, and that one does not pretend the pedals are the law.

The reviewer's front brake, on that particular bike, was poor. The rear, with the hydraulic caliper and regen, was not the complaint. CNET's advertised brake line is hydraulic discs and 220 mm rotors. One bad front brake on a review bike is not a rotor diameter. New Atlas calls the weight 150 pounds-ish before a rider. One hundred fifty pounds is 68 kg. CNET's advertised ready-to-ride weight is about 155 pounds. One hundred fifty-five minus 150 is 5. Those are two sentences, five pounds apart, and neither one is a scale this desk used.

The city rides did not empty the pack

CNET's New York rides are percentages, not a 140-mile loop. One trip through Central Park, about 9 miles, took about 9 points off the display. Nine miles on 9 points is about 1 mile per point on that ride. If the rate held for 100 points, that would be 100 miles, and 3,600 divided by 100 is 36 watt-hours a mile. A later commute on a similar distance used 6 points where the earlier one used 9. Six and nine are not a range. They are two commutes. A May CNET piece said Eco was up to 130 miles and the Normal the writer used was closer to 75. That May Normal is not the November Thrill Normal of 50 miles at 55 mph, and it is not the Cruise Normal of 130 miles at 20 mph. Keep the date on the sentence. The range page is why a percent on one commute is not the slowest row in the table.

A longer September film, Vincent Nguyen, is a 4,700-mile ownership piece made with Onyx and a discount code. It is a collab, not this desk's measurement, so it is not the film above. The charger line on the November cart is 91.97 volts at 10 amps, and the charge-time fields print 0.0 hours. Zero is an empty box, not a full battery. Forty-five amp-hours divided by 10 amps is 4.5 hours, if the brick holds 10 amps from empty to full. The cart does not print that 4.5. A charge that starts above empty is shorter, and the 0.0 does not say which. An older RCR voltage reading is already on the gauge page: 74.1 volts at rest is not this card's 80-volt nominal, and it is not 91.97.

Who it is for

Buy it if you wanted the $4,599 cart, you can store a machine of about 150 pounds, and you have read that 140 miles is the 15 mph row. Skip it if you needed a Class 2 bicycle. Skip it if the job is 75 mph for 140 miles. That pair is not on the card. Thirty miles is the 75 mph row, at 120 watt-hours a mile, and the cart marks the fast modes off-road. This desk did not ride it.
