Xtracycle Swoop ASM: $4,495, $4,499, or $4,999

The Xtracycle Swoop ASM is a longtail, and the price depends on which page you have open. Electrek, Micah Toll, 15 October 2026, prints $4,495. Men’s Journal, 17 September 2026, prints $4,499. Four thousand four hundred ninety-nine minus 4,495 is $4. Xtracycle’s product page prints $4,999. Four thousand nine hundred ninety-nine minus 4,495 is $504. Four thousand nine hundred ninety-nine minus 4,499 is $500. This desk will not average a cart and two reviews into one tag. ASM, Toll writes, stands for Automatic Smile Machine. That is a name. It is not a spec.

Twenty-plus is not a printed 28

Electrek says the Swoop ASM is a Class 3 bike capable of 28 mph, and puts 45 km/h in the same sentence. Twenty-eight times 1.609 is 45.1, so the pair agrees. Men’s Journal says the same 28 mph and the same Class 3. The maker’s page, on the same product, says “20+ mph capable.” Twenty is the Class 1 and Class 2 line. A plus sign is not a measurement. The class chart is why those are different bikes in the eyes of a path. Do not tell a ranger the cart’s plus sign is the review’s 28, and do not tell a buyer the review’s 28 is missing from the cart. Both sentences are on the record. Neither page prints a throttle.

Six hundred thirty watt-hours, and a 60-mile sentence

The pack is a Shimano BT-EN606-A, 630 watt-hours, in the frame and removable. The cart says up to 60 miles depending on the riding. Electrek attributes that claim to Xtracycle and prints 96 km beside it. Sixty times 1.609 is 96.5, so 96 kilometers is the same claim rounded. Six hundred thirty divided by 60 is 10.5 watt-hours per mile, if the claim and the pack are a pair. They did not print the rider, the kids, the assist level, or the hills. It is not a loop. The charger is a Shimano EC-E6002, 120 volts, 2 amps. No watt-hour and no amp become a time without a pack voltage, and the voltage is not on the page. Electrek says the motor and the battery are UL-listed. The cart is more specific: UL 2849 on the EP6 Cargo line, UL 2271 on the pack. The UL page is why those are two stickers, not one mood.

The weight line argues with itself

The cart prints 68.4 pounds and 31.0 kilograms. Sixty-eight point four divided by 2.2 is 31.1, so the pair is one weight. The parenthetical is “without incl. accessories and battery.” “Without” and “including” are not the same instruction. Men’s Journal, which rode one, says 68.4 pounds without the accessories and does not say the battery was off the bike. A 630 watt-hour Shimano pack is not a zero. This desk does not have its mass, so it will not add a guessed pack to 68.4 and call the sum a curb weight. Sixty-eight pounds in Men’s Journal’s opening sentence is the 68.4 rounded. The older Swoop, the EP8, Class 1 bike still listed on the site, prints 62.9 pounds and a 470-pound gross. That is not this motor and not this class. Subtracting 62.9 from 68.4 pretends the two scales match. They have not been shown to.

Twenty-four in front, twenty in back

Both tires are Maxxis Metroloads, 2.4 inches wide. Two point four times 25.4 is 61 millimeters. The front is a 24-inch wheel, the rear a 20. They are not a pair you can rotate front to back and expect the bead to agree. The tire page is the bead, not the brand. The fork is an SR Suntour MOBIE34, 80 millimeters, on the 24-inch wheel. The deck on the geometry table is 32 inches, which they also print as 813 millimeters. Thirty-two times 25.4 is 813. The wheelbase is 54 inches, 1,371 millimeters. Fifty-four times 25.4 is 1,371.6. The overall length is 82 inches, 2,082 millimeters. Eighty-two times 25.4 is 2,082.8. Those are rounding, not a second bike. Brakes, in Electrek, are Tektro four-piston hydraulics. The cart’s snippet this desk could read did not add a rotor diameter. Gears are Shimano CUES Di2, 10-speed, with an auto mode and buttons if you want them. No chainring and no cassette range were in the cells this desk got. A “2+” kid claim is a photo, not a pound rating. Toll’s more-than-100-pound load of power stations is one ride. The cargo guide is why a longtail still needs a printed payload.

Five hundred four dollars is the gap. Twenty-plus miles an hour is not a printed 28.

Pay the number on the page you are actually buying from. If that page still says $4,999, Electrek’s $4,495 is a review, not a coupon. If the cart has dropped to the review price, this page is the one that should change, and the $4,999 stays in the table under it. Do not shop it as the older EP8 Swoop. Do not turn 60 miles into a school run. The missing cells are still the newton-meters, the watts, the payload, and a weight that says, in one sentence, whether the battery was on the bike.
