UrLife E20: 80 Miles Is 7.8 Wh a Mile

The UrLife E20 in IGN’s 9 November deal is a 20-inch step-through with a rear hub, sold by urlifeglobal on AliExpress. The battery line is the one every page agrees on. It is 48 volts and 13 amp-hours. Forty-eight times 13 is 624 watt-hours. The range line on that same IGN page is up to 80 miles, under ideal conditions, and the next sentence says the real distance depends on speed, terrain, and elevation. Six hundred twenty-four divided by 80 is 7.8 watt-hours a mile. That is the claim’s rate. It is not a loop. A 20-by-3.0 tire does not spend 7.8 watt-hours a mile at the speeds this bike is sold on. The range page is why, and the watt-hour page is the multiplication.

750 watts is not 500, and neither is 1,000

IGN’s headline says a 1,000-watt bike. The body says 750 watts, 1,000 peak. One thousand divided by 750 is 1.33, so the peak sentence is a third above the rated sentence. The maker’s blog table says the same pair, 750 rated and 1,000 peak. An owner’s 4 October video says his bike is 500 watts continuous and 1,000 peak. One thousand divided by 500 is 2. A September write-up that read an Amazon title also says 500 watts rated. A 31 October deal note says 750 watts peak, while the picture on that same thread says 1,000 watts peak. Those are four motor sentences. This desk will not average 500 and 750 into 625. The federal line for a low-speed electric bicycle is a motor of less than 750 watts. Seven hundred fifty is not less than 750. Five hundred is. The class still fails on the throttle, below. The motor page is why a peak and a continuous figure are not one watt.

A throttle that the seller takes to 28 mph is not Class 2, and it is not Class 3. Class 3 does not get a throttle.

28 mph on a throttle is not a class

The speed line is 28 mph. A product graphic prints 45 km/h. Forty-five divided by 1.609 is 28.0 mph, so that pair matches. The maker’s blog calls it Class 3 performance. Class 3 is pedal assist to 28 mph and no throttle. A write-up of the listing says UrLife’s US version reaches 28 mph with a throttle. A comment on a deal thread says a nearly identical bike holds 28 mph on the throttle. The owner in the video weighs 193 pounds and saw 26 mph, not 28. Class 2 stops the throttle at 20 mph. A throttle past 20 fails Class 2. A throttle at all fails Class 3. Pedals are there, and that is not enough. The class chart is the test. This desk did not see a class sticker.

The $60 coupon is not a $264 discount

IGN’s crossed price is $509.99. The new-customer price after code DBDEAL60 is $245.72. Five hundred nine dollars and ninety-nine cents minus $245.72 is $264.27. That $264.27 divided by $509.99 is 51.8 percent off. IGN printed 52 percent. Returning customers, same code, are $257.72. That is $12 more, exactly. The coupon itself is $60. Five hundred nine dollars and ninety-nine cents minus $60 is $449.99, not $245.72. The other $204.27 is a sale the page does not itemize. If DBDEAL60 dies, IGN says try USAFF55, which is $55, not $60. On 6 March the same IGN format had the bike at $288.36. A 9 November roundup had it at $339.99. The maker’s August blog says under $300 in one paragraph and about $700 in a comparison table on the same page. Four prices. None of them is a test of the pack.

A 3.0-inch tire, and a 265-pound line that moves

IGN says 20-inch fat tires and does not print the width. The maker’s table says 20 by 3.0. Three inches is a wide 20-inch tire. It is not a 4.0. The tire page is that cut. The frame is carbon steel, about 60 pounds. The maker also writes 27 kg. Twenty-seven kilograms is 59.5 pounds, so the two weight lines are the same claim, rounded. IGN and the maker call 265 pounds the load. A deal page calls 265 pounds the rear rack. A rider limit and a rack limit are not the same part. Two hundred sixty-five pounds is 120 kg, which is the kilogram the maker printed. Brakes are discs. No rotor size is printed. One owner said he would rather have hydraulic. Gears, where a page prints them, are a Shimano 7-speed. The motor is a rear hub, so those gears are not a mid-drive. The maker’s blog says the frame folds, the pack comes out from under the seat, and the bike is IP54. It also says UL 2849. This desk did not see the certificate. A March owner video, from a rider who is 5 feet 10, says the bike is smaller than he wants. He says a 5-foot-4 rider on the same bike found the size right.

Who it is for

Read it as a cheap 624-watt-hour step-through with a rack, if the price on the day you open the cart is the one you mean to pay. Do not read 80 miles as a plan. Seven point eight watt-hours a mile is the arithmetic of the claim, and the owner who has put months on one tells people to expect 20 to 35. Do not read it as Class 2 or Class 3 while a throttle is in the 28 mph sentence. And do not pick 750 or 500 until the listing you are buying prints one continuous watt. This desk did not ride it.
