sixblues EB3L

The listing states a 20 mph top speed and a pure electric mode, so the motor can move the bike without pedalling. That is the Class 2 shape, which is treated as a bicycle in nearly every state, including the seven jurisdictions that ban Class 3 (New Jersey and Hawaii add registration).

The open question is the wattage. US law uses the rated figure, a motor's continuous output, not the peak it draws briefly when accelerating. The federal definition of a low-speed electric bicycle in 15 U.S.C. §2085 is written around 750 W and 20 mph on motor power alone, and most state class laws copy that 750 W figure. sixblues gives one number, 750 W, and never says whether it is rated or peak. The HopCycle EB3L, with the same model number, torque and speed cap, was listed as "750W Rated Motor with 1000W Peak Power", so 750 W is most likely this motor's rating and we treat the EB3L as Class 2 on that basis. If a path authority or your building asks for paperwork, get sixblues to confirm the rating in writing. Path and sidewalk rules vary by state and city; see our street-legal-by-state guide.

UL 2849 covers the complete e-bike electrical system (battery, motor, controller and charger tested together) and UL 2271 covers the battery pack alone. They are the two standards US rules name: New York City's Local Law 39 of 2023 bars the sale in the city of e-bikes and batteries not certified to one of them, California's SB 1271 brought certification requirements into force on 1 January 2026, and a growing number of apartment buildings ask for a certificate before a battery may charge indoors.

The listing says "Safety certified to ANSI/CAN/UL 2849 by SGS for the entire e-bike" and "ANSI/CAN/UL 2271 by SGS for the lithium-ion battery". Naming the laboratory is what gives that weight: "UL certified" alone is a marketing phrase, while a standard plus a lab is something the seller can back with a certificate number. The HopCycle EB3L listing named neither standard. The sixblues EB3S carries the same pair from the same lab, and the Funhang EB-M1 at $309.99 names SGS for its battery and TUV for the whole bike. If certification decides your purchase, ask sixblues for the certificate numbers before you order.

The listing describes a 10.4 Ah "waterproof" and "anti-theft" pack with a 4-5 hour charge, but no voltage, so it states no capacity in watt-hours, the number range depends on. The HopCycle EB3L description gave 36 V for its 10.4 Ah pack, and the EB3S in this Amazon family works out to 36 V (540 Wh from 15 Ah). At 36 V the EB3L holds 374 Wh. A 26-inch hardtail on standard tires draws roughly 15-22 Wh per mile, so on that assumption:

• 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 / 60 miles = 6.2 Wh per mile, which is what the "up to 60 miles" claim requires

A 26-inch bike with a rider aboard does not run on 6 Wh per mile, so treat 60 miles as a marketing number. About 20 miles is the honest planning figure, enough for a commute of around 8 miles each way. If sixblues confirms a 48 V pack instead, every figure above rises by a third, one more reason to ask for the voltage before you buy.

• Mechanical disc brakes front and rear: normal at this price, but they need cable adjustment as the pads wear.
• Front suspension only. The listing names a front fork and nothing at the rear, so "electric mountain bike" here means broken pavement and gravel paths, not trails.
• A smaller pack than its sibling. The EB3S carries 15 Ah against this bike's 10.4 Ah, about 44% more charge on what is very likely the same voltage, for $314.99 against $299.99.
• No published weight or payload. The HopCycle EB3L listing quoted 49.6 lb and a max load of 264 lb in one place, 330 lb in another. sixblues gives neither, so a heavier rider should ask first.
• No brand website. We found no sixblues site for spares or manuals, so support runs through the Amazon seller, backed by a 12-month warranty.
• The app is a title claim. The title says "APP Control", but no bullet describes what the app does.

The HopCycle EB3L is the version we covered first: same model number, pack, torque and speed cap, no certification documented, and now off sale on Amazon. The sixblues EB3L is that specification with UL 2849 and UL 2271 added. The sixblues EB3S shares this bike's Amazon listing family and certification line with a larger 15 Ah, 540 Wh battery. The EB3L model number has appeared under more than one brand, so treat it as a shared factory platform; we cannot confirm every version comes off the same line.

Buy this if you want UL 2849 and UL 2271 on the listing and a 20 mph Class 2 specification, for a commute of up to about 8 miles each way on paved roads and light gravel. Pick the EB3S if your ride is longer, since the larger pack is the main difference on paper. Skip it if you need hydraulic brakes, a published payload rating or a torque sensor, none of which this listing offers.
