BIGUODIR RX80 E-Bike Review: Does 2000W Dual Motor Justify $1,349?
The BIGUODIR RX80 electric mountain bike delivers 2000W peak dual-motor power, a 960Wh battery, and a 400 lb weight capacity at $1,349 — a strong value for off-road and heavy-duty riders, but its 74.8 lb non-folding frame rules it out for small apartments or riders under 5'6".

How this e-bike scores for different riding styles
Dual motors with 2000W peak power, 26x4.0 fat tires, dual suspension, and 35° climbing capability make this exceptional for trails, mountains, mud, snow, and beach riding.
Peak 2000W dual motors delivering 30 mph top speed and 150Nm torque with 35° climbing ability offer thrilling performance, though not the absolute maximum in the category.
The 400 lb weight capacity, rear rack, sturdy non-folding frame, and powerful dual motors provide excellent cargo hauling capability for groceries and deliveries.
Cruise control, comfortable dual suspension, USB charging, and multiple riding modes make it excellent for casual rides, though the weight may be excessive for purely leisurely use.
The 60-65 mile pedal assist range and removable battery support daily commutes, but the 74.8 lb weight and non-foldable design make storage and transport challenging for urban commuters.
Non-foldable frame at 76.9 inches long and 74.8 lbs weight makes this impractical for compact storage, apartments, or public transit use.
Our Verdict
The BIGUODIR RX80 is a full-suspension electric mountain bike powered by two hub motors producing 2000W peak output, pushing it to a governed 30 MPH. The 48V 20Ah (960Wh) battery delivers 43 to 65 miles per charge across five pedal assist levels, giving riders real control over range versus speed. Front and rear suspension paired with 26 x 4.0-inch fat tires absorbs sand, snow, mud, and rocky trail impact, while dual hydraulic disc brakes — 160mm front, 180mm rear — provide reliable stopping power at full speed.
At $1,349, the BIGUODIR RX80 e-bike sits above entry-level fat-tire models but delivers a spec sheet that typically costs $1,600 or more from premium brands: dual motors, full suspension, Shimano 7-speed gearing, hydraulic brakes, UL certification, and a 1-year warranty. The 400 lb total weight capacity makes it one of the few off-road electric bikes that reliably supports heavier riders or cargo hauling. A built-in LED headlight, USB charging port, LCD display, IPX4 waterproofing, and cruise control complete the package without requiring add-on purchases.
The BIGUODIR RX80's trade-offs are weight and footprint. At 74.8 lbs with a rigid non-folding frame, it needs dedicated garage or shed storage and requires two people to load into a vehicle. Riders shorter than 5'6" will find the 26-inch frame geometry uncomfortable. The 4-to-6-hour charge time rewards advance planning. For riders who need a lightweight city commuter, lighter single-motor options make more sense. But for those who want a capable electric mountain bike that handles extreme terrain and heavy loads without paying a $2,000+ premium brand price, the BIGUODIR RX80 delivers a strong watts-per-dollar ratio with meaningful safety credentials.
What We Like
- 2000W peak dual motors sustain 30 MPH and climb 35-degree inclines — comparable to electric mountain bikes priced $400 higher
- 960Wh (48V 20Ah) battery provides 43–65 miles per charge with five pedal assist levels for precise range management
- 400 lb total weight capacity exceeds most fat-tire e-bikes in this price class, supporting heavier riders and cargo loads
- Dual hydraulic disc brakes (160mm front, 180mm rear) combined with front-and-rear full suspension deliver consistent control on off-road terrain
- UL-certified, IPX4-rated, 1-year warranty, and Shimano 7-speed gearing add long-term reliability value at the $1,349 price point
What Could Be Better
- 74.8 lbs makes the BIGUODIR RX80 one of the heaviest bikes in its class — loading it into most vehicles requires two people
- Non-folding rigid frame requires at least 77" × 28" of floor space, making it impractical for apartment dwellers or tight storage areas
- Minimum rider height of 5'6" excludes shorter adults due to the 26-inch frame geometry
- 4–6 hour full recharge from empty with no fast-charge option listed can interrupt back-to-back riding days
- Only 1 verified buyer review available at time of review, making long-term durability and customer service response difficult to assess

Frequently Asked Questions
Common questions about1000W/2000W Dual Motor Electric Bike Adult, 48V 30Ah/20Ah Battery, 26'' Fat Tire Full Suspension Ebike, 30MPH Dual Hydraulic Disc Brakes, 120Miles Off Road Mountain Beach Ebike, UL Certified
How fast can this bike go and is it street legal?
The bike can reach 30 miles per hour at top speed. You can adjust the speed limit through the display to follow your local laws, since some places limit e-bikes to 20 or 28 mph on public roads.
How far can I ride before the battery dies?
You can go 43 miles if you just use the throttle without pedaling, or 60 to 65 miles if you pedal and use the electric help. How far you actually go depends on how heavy you are, if you're going uphill, and how much you pedal.
Can this bike handle riding in the rain or on the beach?
Yes, the bike has IPX4 waterproof rating which means it can handle water splashing on it from any direction. The fat tires work great on sand and the waterproof parts protect the battery and electronics.
How heavy is this bike and can I lift it myself?
The bike weighs 74.8 pounds which is pretty heavy - about as much as a large dog. Most people will find it hard to lift alone, especially to put it on a bike rack or carry up stairs.
What's the difference between the riding modes?
You can ride four different ways: regular pedaling with no motor, pedal assist where the motor helps you pedal (5 levels of help), throttle only where you don't pedal at all, and cruise control that keeps you at the same speed without holding the throttle.
