AYOLNY 26" Electric Mountain Bike

The Amazon page sells three configurations under one listing, and they are not the same bike with a different colour. This page reviews the cheapest, at $299.99: the 1000 W peak motor, the 36 V 10.4 Ah battery and 26 x 1.95 tires. A second configuration uses the same 36 V battery on 26 x 2-inch tires and adds two facts the base listing leaves out: a 750 W rated motor and a 264 lb maximum load. The dearest has a 1500 W peak (750 W rated) motor and a larger 48 V 13 Ah (624 Wh) battery that AYOLNY quotes at up to 70 miles.

If range matters to you, the 48 V build is the one to look at, because it fixes the base bike's main weakness. Check which option is selected before you add it to the cart: the listing's headline photo and price change with the option, and the summary line above the buy button is easy to miss on a phone.

The base battery is 36 V x 10.4 Ah = 374 Wh, and AYOLNY claims up to 40 miles per charge in pedal-assist mode. A 26-inch hardtail on 1.95-inch tires draws roughly 15-22 Wh per mile with a rider aboard:

• 374 Wh / 22 Wh per mile = 17 miles (throttle-heavy riding, hills)
• 374 Wh / 18 Wh per mile = 21 miles (our planning figure)
• 374 Wh / 15 Wh per mile = 25 miles (light rider, low assist, flat ground)
• 374 Wh / 40 miles = 9.4 Wh per mile, which is what the 40-mile claim requires

Nine to ten watt-hours per mile is reachable only at the lowest assist level by a light rider pedalling hard on flat ground, so treat 40 miles as a best case. About 20 miles is the honest planning figure, enough for a commute of up to 8-10 miles each way with margin. The listing calls the battery "integrated" and does not say whether it removes for charging, which matters if you plan to charge indoors and store the bike somewhere else. Ask the seller before you buy if that is your situation.

On speed, it has the Class 2 shape. The listing states a 20 mph maximum, and Class 2 allows a throttle up to 20 mph and is treated as a bicycle in nearly every state, including the seven jurisdictions that ban Class 3 (DC, Kentucky, Massachusetts, Montana, North Carolina, Pennsylvania and South Carolina). The open question is the motor rating. The federal low-speed electric bicycle definition in 15 U.S.C. §2085 caps the motor at 750 W, and the states that use the three-class system follow it. This configuration's listing gives only a 1000 W peak figure. Peak is the brief maximum a motor draws when accelerating, and the two sibling configurations both state 750 W rated, which suggests the same rating here, but this listing does not say so. On paperwork alone we cannot confirm the class, so we do not assign one. New Jersey and Hawaii require registration for e-bikes; check your state for path and sidewalk rules.

The base listing says that "both the complete ebike and lithium-ion battery carry SGS safety certifications". SGS is a real testing laboratory, but the sentence does not name a standard. The 26 x 2-inch configuration is more specific: "SGS certification to 2849" for the whole bike and "certified to 2271 by SGS" for the battery, which are UL 2849 and UL 2271, the two standards US rules name. New York City's Local Law 39 of 2023 bans the sale of e-bikes and batteries not certified to one of them, California's SB 1271 has required certification for e-bikes sold there since January 2026, and more apartment buildings ask to see a certificate before they allow indoor charging.

It is likely that the same certificate covers all three builds, since they share a frame, a seller and a listing, but likely is not documented. If certification decides your purchase, ask AYOLNY for the certificate number for the exact configuration you are buying. Two bikes we review document both standards on their own listings: the sixblues EB3S at $299.99 and the Funhang EB-M1 at $219.99.

The seven-speed drivetrain gives you usable gears for pedalling with the motor off, and AYOLNY describes it as precise rather than naming the maker. The G51 display shows speed, trip distance and remaining battery, pairs with an app for riding settings, and has a USB port for charging a phone. The listing says the bike ships 90% pre-assembled with 12 months of after-sales support.

The listing does not state the brakes, the suspension, the bike weight or, on this configuration, the payload. Comparable 26-inch hardtails at this price usually have mechanical disc brakes, a basic coil fork, a weight of 50-60 lb and a 260-330 lb payload, and the sibling configuration states 264 lb. If you are near that limit, or need hydraulic brakes, confirm before ordering rather than assuming.

Buy this if you want a full-size, 26-inch e-bike with gears and a 20 mph cap at the lowest price, and your rides are under about 20 miles a charge. It is also the bike more Amazon shoppers are choosing than any other electric mountain bike right now, which counts for something at this price.

Skip it if range matters (the sixblues EB3S has 45% more battery for the same money, and the AYOLNY's own 48 V build fixes this too), if you need documented UL certification on the exact listing you buy, or if you need a published weight and payload. Riders who mostly cover short, flat trips on a tighter budget should look at the Funhang EB-M1, which costs less and documents both UL standards.
