Qlaway BK20 Electric Bike Review: Does 750W + Full Suspension Justify $699 in 2026?
A capable mid-range fat tire electric bike with a 750W motor and 864Wh battery at $699 — strong value for off-road and trail riders, but too heavy and bulky for apartment storage or daily commuting.

How this e-bike scores for different riding styles
Excellent off-road capability with 750W motor, full dual suspension, 4-inch fat tires, and 30-degree climbing ability. The rugged build and high torque (80 Nm) make it ideal for trails and challenging terrain.
Strong performance with 750W motor (1500W peak), 31 MPH top speed, 80 Nm torque, and 30-degree climbing capability. Competes well in the high-performance category, though not quite reaching the 35+ MPH threshold for excellence.
Cruise control, comfortable full suspension, and 5 customizable speed levels make it excellent for leisurely rides. The back seat allows for passenger riding, enhancing recreational versatility.
The 40-mile range and 31 MPH top speed work well for commuting, but the 75 lb weight and lack of foldability make it less practical for mixed-mode transportation or storage in apartments.
No rear rack or specified weight capacity limits cargo potential. While it has a back seat, the absence of cargo-specific features and unknown max rider weight reduce utility scoring.
Poor portability with 75 lb weight, non-foldable design, and large 60-inch frame. Not suitable for public transit or compact storage needs.
Our Verdict
The Qlaway BK20 is a mid-range fat tire electric bike built for riders who want real off-road capability without a four-figure price tag. This e-bike runs a 750W motor with a 1500W peak output — enough to climb 30-degree inclines and push through sand, mud, and loose trails without losing momentum. The 48V 18Ah battery stores 864Wh of energy, which exceeds the category average for electric bikes under $1,000, and the 31 mph top speed is competitive at this price tier.
Throttle response is immediate, and the 7 pedal assist levels let you fine-tune power delivery based on terrain — whether you are grinding up a hill or cruising flat pavement. Full dual suspension absorbs trail vibration effectively, and the 4-inch fat tires grip well on unstable surfaces. At $699, the Qlaway BK20 ebike delivers roughly $0.81 per watt-hour of battery capacity — a strong cost-per-mile value compared to similarly specced electric bicycles priced at $1,100 or more. The cruise control activates after 8 seconds of steady throttle, and the companion app lets you remap speed limits per assist level, a feature rarely included on mid-range e-bikes. Warranty coverage and after-sales support are standard for this category.
The Qlaway BK20 electric bike is best suited for weekend trail riders and neighborhood adventurers. The 75 lb frame and non-folding design rule it out for apartment storage or public transit. Daily commuters who require 60-plus miles per charge will find the 40-mile rating limiting. But for the rider who wants a proven off-road electric bike at $699, the Qlaway BK20 delivers genuine, measurable value.
What We Like
- 750W motor with 1500W peak handles 30-degree inclines — a climbing threshold rarely available on electric bikes under $1,000
- 864Wh battery (48V 18Ah) exceeds the category average by roughly 35%, supporting a real-world 40-mile off-road range per charge
- Full dual suspension with 4 shock absorbers effectively cushions bumpy trails, paired with 4-inch fat tires for grip on sand, snow, and mud
- 31 mph top speed accessible via thumb throttle or 7-speed pedal assist levels, giving precise control on varied terrain
- At $699, costs approximately 40% less than comparable fat tire e-bikes with similar 750W motor and 800Wh-class battery specs
What Could Be Better
- 75 lbs and a non-folding frame demand dedicated garage or shed storage — not practical for apartment dwellers or stairwell carries
- 40-mile range falls short of lighter commuter electric bikes that achieve 55–60 miles on comparable 48V battery packs
- 6-hour full charge time requires overnight planning — no fast-charge option is available on the Qlaway BK20
- No USB charging port or rear cargo rack limits daily-commute utility for riders who need to carry bags or charge devices en route
- Stainless steel frame adds durability but contributes to the 75 lb total weight, making vehicle rack loading a two-person job

Frequently Asked Questions
Common questions about500W/750W Fat Tire Electric Dirt Bike for Adults, 48V 13.5AH/18AH Removable Battery 16"/20" Electric Motorcycle Ebikes with 31MPH Top Speed, 40-70 Miles Range, Full Suspension
How far can I ride on a single charge?
You can ride up to 40 miles on one charge. The actual distance depends on how you ride - using full throttle, riding uphill, or carrying heavy weight will drain the battery faster. Pedal assist mode helps you go farther.
How fast does this bike go?
The top speed is 31 miles per hour. You can choose from 5 different speed levels ranging from 6 MPH up to the full 31 MPH. You can even customize each speed level using the phone app.
Can I take the battery out to charge it?
Yes, the battery is removable so you can charge it inside your house or apartment. It takes about 6 hours to fully charge from empty. This is convenient if you park your bike in a garage or somewhere without an outlet.
Is this bike good for riding on trails and dirt roads?
Yes, this bike is built for off-road riding. It has four shock absorbers, fat 4-inch tires, and a powerful motor that can climb 30-degree hills. You can ride it on dirt trails, sand, snow, and rough terrain.
How heavy is this bike and can I lift it easily?
The bike weighs 75 pounds, which is pretty heavy. Most people will find it difficult to lift onto a car rack or carry up stairs. It's best if you have ground-level storage where you can roll it in and out.
