Stealth Bomber 72V: 200 Amps Is 14.4 Kilowatts, Not 15

The shop card called a Stealth Bomber is a 72-volt QS273 hub bike, not the hand-built machine Stealth Electric Bikes describes in Melbourne. Emoto Superstore lists a 15,000-watt version at $3,499, sold out, with a 200-amp controller and a 56-amp-hour pack. Seventy-two times 200 is 14,400 watts. Seventy-two times 56 is 4,032 watt-hours. The 5-amp charger needs 11.2 hours for that pack. The page prints 6 to 8.

The short answer

The shop card called a Stealth Bomber is a 72-volt QS273 hub bike, not the hand-built Melbourne machine. Emoto Superstore lists 15,000 watts at $3,499, sold out, with a 200-amp controller and 56 amp-hours. Seventy-two times 200 is 14,400 watts. Seventy-two times 56 is 4,032 watt-hours. A 5-amp charger needs 11.2 hours. The page prints 6 to 8. This desk did not ride it.

Stealth Electric Bikes, in Melbourne, says it has built off-road machines since 2008, starting with a B-52 Bomber, and that the bikes are still designed and hand-built there. That about page does not print 72 volts, a QS273 hub, or 15,000 watts. The cards this desk opened on 26 October 2026 use the Bomber name for a steel-frame hub bike with a box where a tank would be, and they sell it in a menu from about 5,000 watts to 15,000. Emoto Superstore’s listing asks $3,499, down from $4,499, shows 14 reviews, says sold out, and says the bike needs assembly. It also says the shop does not provide any document for the bike. This is a reading of those cards. It is not a SickEBike ride, and it is not a reading of the Melbourne hangar.

Stealth Bomber 72V graphic: 72 times 200 amps is 14.4 kW, 72 times 56 amp-hours is 4,032 Wh, charge math is 11.2 hours
The sheet on this page, for the 15 kW shop card, not the Melbourne hand-built bike. Seventy-two times 200 is 14,400 watts, 14.4 kilowatts of controller input if the voltage holds. The sticker says 15. That is not a dyno. Seventy-two times 56 is 4,032 watt-hours. Fifty-six amp-hours divided by a 5-amp charger is 11.2 hours before the taper. The listing says 6 to 8. It is an off-road electric motorcycle, not a Class 1, 2, or 3 bicycle. Shop claims, not a ride.

One name, four watt stickers

Emoto Superstore’s product page, opened 26 October 2026, sale price $3,499 from $4,499, sold out. The 12-kilowatt and 5-kilowatt rows are on the same page’s weight and motor notes, not a second checkout. eMoto Bykes, a different shop, prints different tops for the same watt words. Do not average them.

15 kW card8 kW cardThe other rows
Pack72 V, 56 Ah. Seventy-two times 56 is 4,032 watt-hours. A 70 Ah option is named for a 75-mile range. Seventy-two times 70 is 5,040.72 V, 40 Ah. Seventy-two times 40 is 2,880 watt-hours.Weight table: 12 kW with 45 Ah is 205.3 lb. 5 kW with 26 Ah is 154.34 lb. Seventy-two times 45 is 3,240. Seventy-two times 26 is 1,872. No 15 kW weight is in that table.
Controller72 V, 200 A Sabvoton. Seventy-two times 200 is 14,400 watts. The sticker says 15,000. Fifteen thousand divided by 72 is 208 amps.72 V, 150 A. Seventy-two times 150 is 10,800 watts. The sticker says 8,000. Eight thousand divided by 72 is 111 amps.The page says every model is a QS273 hub, 5 to 15 kW, wound from 2.5T to 5T. It says 2.5T is less torque and more speed, and 5T is the reverse. It does not print a newton-meter.
Speed and range75 mph, 65 miles. The 70 Ah line is 75 miles. Sixty-five miles on 4,032 watt-hours is 62 watt-hours a mile.58 mph, 50 miles. Fifty miles on 2,880 watt-hours is 58 watt-hours a mile.eMoto Bykes prints 70 mph and 65 miles for 15 kW, and 50 mph and 50 miles for 8 kW. Same battery sizes. Different tops.
Charge5 A charger. Fifty-six amp-hours divided by 5 amps is 11.2 hours, before the taper. The page prints about 6 to 8 hours for the bikes as a group.Also a 5 A charger. Forty divided by 5 is 8.0 hours. That is the only pack in this pair that can sit next to an 8-hour line, and only if the current never falls.A 70 Ah pack at 5 A is 14 hours. The store’s charger page also sells a 10 A unit for the 8, 12, and 15 kW bikes, and a 3 A unit for the 5 kW, 26 Ah bike. The product bullets say 5 A.
ChassisKKE fork, DNM rear shock, Tektrol hydraulic discs, 203 mm rotors, LCD, a key, five pedal-assist modes. Optional 26-by-3 or 26-by-4 tires.Same brake and charger lines. The weight cell for this pack is 198.4 lb.A dimensions block on the same Emoto page says steel, the string “1/2mm,” fork travel 8 inches, and a wheel of 21 by 3. Eight inches is 203 mm. That 203 is the travel line, not the rotor, unless the page meant one number twice. The tire options and the 21-inch line are both printed.

Hallomotor’s 72-volt, 8,000-watt card is a third machine wearing the name. The price this desk saw was $4,858.99, down from $6,859. The pack is 72 volts and 42 amp-hours of Molicel P42A, which is 3,024 watt-hours, not 2,880. The speed line is 120 to 135 km/h, which is 75 to 84 mph. The wheels are 19-inch. The frame line says 2.0 mm steel, which is a thickness the Emoto card does not print. Theebikemotorkit’s 8,000-watt title says 70 mph and, lower down, 56 to 62 mph, and a range of 45 to 50 miles. Volt Cycle’s 15,000-watt block says 80 mph and a 7-speed, and then calls a Sabvoton a “150A charger controller,” which is a controller and a charger in one noun. Read the page you are paying. The motor guide is why a watt on a sticker and a watt from volts times amps are different sentences.

Fourteen thousand four hundred is the 200-amp line

A controller amp, times the pack voltage, is an electrical ceiling, not a dyno sheet. At 72 volts a 200-amp controller is 14.4 kilowatts if the voltage holds, which it does not once the pack sags. The 15,000-watt word needs 208 amps at 72 volts. The card’s own controller is 200. The 8,000-watt word needs 111 amps. That card’s controller is 150, which is 10.8 kilowatts, so the controller can pass more current than the motor’s name. Neither number is a measured output. The winding note, 2.5T against 5T, is the shop saying the same hub can be built for speed or for torque. FewMoto’s January 2026 film says a bike marketed as 20 kilowatts arrived as 12, and a dongle took the controller to about 16. That is one bike. It is not a reason to add the shop menu together.

Seventy-two times 200 is 14,400 watts. The sticker says 15,000. The 56-amp-hour pack is 4,032 watt-hours, and a 5-amp charger does not refill it in 6 hours.

Eleven hours, not six

Amp-hours divided by charger amps is the ideal time if the current stays constant. Fifty-six divided by 5 is 11.2 hours. Forty divided by 5 is 8.0. Seventy divided by 5 is 14. A lithium charge tapers, so the real clock is longer than those. Emoto prints about 6 to 8 hours once, under the whole family. Six hours would need 9.3 amps into a 56-amp-hour pack. The bullet says 5. The 40-amp-hour pack is the only one of the three that meets an 8-hour ideal, and only before the taper. The charging page is why one sentence cannot cover three tanks. The parts page selling a 10-amp charger for the bigger bikes would cut the 56-amp-hour ideal to 5.6 hours. That charger is not the 5-amp bullet.

The watt-hour page is 72 times the amp-hours. Four thousand thirty-two watt-hours is a large tank. Sixty-five miles on it is 62 watt-hours a mile. Fifty miles on 2,880 is 58. Seventy-five miles on 5,040 is 67. Those three claims are in the same neighborhood, which is unusual, and they are still claims. A 198-pound bike at 58 or 75 mph does not sip watt-hours. The range page is why a mile number without a speed and a rider is a brochure. FewMoto’s May 2025 range film, a 12-kilowatt bike with a 70-amp-hour pack, shows 22.44 miles at 76.4 volts, a max of 56 mph and an average of 26, then another 20.63 miles with a max of 57. He says it should get at least 60. That sentence is a prediction at mile 20, not an empty pack. This desk did not find the finished drain.

Seventy-five miles an hour is not a class

The federal low-speed bicycle, 15 U.S.C. § 2085, is pedals, a motor of less than 750 watts, and less than 20 mph on the motor alone. These cards have pedals, five assist modes, and a throttle. Eight thousand watts is not less than 750. Fifteen thousand is not. Fifty-eight miles an hour is not under 20, and 75 is not. A 7-speed on one shop’s 5-kilowatt card does not pull the hub back into a bicycle class. The US law pillar is the state layer, and it does not have a box for an undocumented 75 mph hub. Emoto’s own line is that it provides no document for the bike, including customs documents. Missing paperwork is not a registration. A Sur-Ron Light Bee X is the smaller off-road motorcycle people already know is not a Class 3. This menu is heavier and, on the stickers, faster. The helmet guide is why a CPSC bicycle lid is the wrong object once the card says 58 or 75 mph. BHSI’s page points a 28 mph e-bike at a light motorcycle helmet. These cards are past 28.

The public film is one 12-kilowatt bike, sold as 20

FewMoto, 4 January 2026, 16 minutes. About 5,600 views when this desk looked. He says the bike was marketed as 20 kilowatts and arrived as 12, that a Bluetooth dongle took the Fardriver to about 16, and that the motor is a QS273 in a 2.5T wind, which he reads as about 75 mph and low torque. He calls the stock brakes dinky. The title asks if it is worth $3,500. A later sentence says he wants to say the range was about 80 miles. Wanting to say is not a loop this desk timed. Wardy’s February 2025 ride is a different bike: a 48-volt pack, then 60, then a 72-volt pack swapped in, with a spoken top around 50 mph.

The hub is the motor. A 7-speed, where a card even prints one, is for the pedals. The hub page is that split. Brakes are a 203 mm hydraulic disc with a brand spelled Tektrol. eMoto Bykes then writes Tektro E725 in a later blob. This desk will not promote the spelling into a piston count. Two hundred three millimeters of rotor on a 198-pound bike at a claimed 75 mph is a sentence you should read next to the film that called the brakes dinky. The brake guide is why rotor diameter is not a stopping distance.

Who it is for

Buy one of these cards only if the quote in front of you still says 72 volts, the amp-hours you multiplied, the controller amps you multiplied, and a QS273, and if you already know it is an off-road electric motorcycle that the shop will not document. The $3,499 figure is one Utah listing, sold out, for a bike that needs assembly. It is not the Melbourne price, because Melbourne did not print this card. Skip 15,000 watts until someone shows 208 amps at 72 volts, or a dyno. Skip 6 to 8 hours on a 56-amp-hour pack with a 5-amp brick. Skip 75 mph as a class, a path, or a bicycle helmet. Skip the 19-inch Hallomotor and the 21-inch dimension line if the bike in the crate is on 26-inch tires. This desk did not ride it.

Questions people ask

Is the 15,000-watt Stealth Bomber actually 15 kilowatts?+

The Emoto card pairs 15,000 watts with a 72-volt, 200-amp controller. Seventy-two times 200 is 14,400 watts. Fifteen thousand watts at 72 volts would be 208 amps. The controller line is 200.

How big is the battery?+

The 15,000-watt card says 72 volts and 56 amp-hours, which is 4,032 watt-hours. The 8,000-watt card says 40 amp-hours, which is 2,880. A 70-amp-hour option is 5,040. Do not treat them as one tank.

Is it a Class 3 e-bike?+

No. A Class 3 bicycle assists to 28 mph with a motor under 750 watts. These cards print 58 or 75 mph and 8,000 or 15,000 watts. The shop also says it provides no documents for the bike.

Is there a review video?+

FewMoto posted a 16-minute review on 4 January 2026. He says a bike sold as 20 kilowatts arrived as 12, and a dongle took it to about 16. That is one QS273, not a lab test of every watt sticker.

Keep riding
