Are you curious whether the “TST Electric Bike for Adults 1500W Peak 20″ Fat Tire All-Terrain E-Bike 60/110 Miles 28MPH Electric Dirt Bike for Road Sand Mountain Snow – 48V 15/25AH Battery Powered Electric Motorcycle” is the right ride for your next adventure?
Quick take: what this bike promises for you
You get a powerful 1500W peak motor that’s meant to tackle steep climbs and rough surfaces with ease. The product targets riders who want an all-terrain, long-range e-bike with fat tires, full suspension, and multiple riding modes for both off-road and commuting use.
Who this bike is best for
If you enjoy long rides across mixed terrain—beach sand, trails, or groomed roads—you’ll appreciate the traction and power. You should consider this bike if you want serious torque for climbing, a removable battery for easy charging, and the flexibility of throttle and pedal assistance modes.
Design and build quality
The frame and components are designed for rugged use, with a beefy frame geometry and integrated rear rack to carry gear. You’ll notice the extended seat and wide tires immediately, and the overall build aims to balance durability with comfort for extended rides.
Frame and weight considerations
You should expect a sturdy frame that supports the heavy components, including the large battery and motor. The trade-off is typically weight; this bike is heavier than a standard commuter e-bike, so you’ll want to plan for transport and storage that accommodate that extra mass.
Motor performance and riding power
The 1500W peak motor and 90 N·m of torque are the headline specs. You’ll be able to climb up to a 35-degree slope, according to the manufacturer, and reach a top speed of up to 28 mph when the app allows it.
Real-world acceleration and hill climbing
In practical terms, you’ll feel strong acceleration from a stop and reliable assistance on steep grades. The torque helps maintain momentum in soft sand or on rocky climbs, so you won’t be relying solely on brute force from your legs.
Battery system and range
The bike ships with a waterproof removable 48V battery, typically offered in 15Ah and 25Ah configurations. You’ll have two charging methods and charging completes in about 5 hours for the smaller battery, making daily charging feasible.
Range expectations and factors
Advertised range sits around 60 miles with the 15Ah battery and up to 110 miles with the 25Ah option. You should treat those figures as best-case estimates; actual range will vary based on riding mode, rider weight, terrain, wind, and average speed. Using full throttle constantly will reduce range significantly compared with mixed pedal-assist use.
Tires, braking, and suspension: safety and handling
The 20×4.0-inch puncture-proof fat tires give you improved traction on sand, snow, and loose rock. Dual mechanical disc brakes provide dependable stopping power, and the full suspension smooths bumps for a more controlled ride.
Night visibility and rider awareness
You’ll get 360° LED lighting that includes a headlight, brake light, and turn signals for nighttime clarity. The lights improve your visibility to other road users and help illuminate uneven paths during low-light rides.
Riding modes and control options
You can switch between pure electric (throttle), pedal-assist (PAS), and traditional pedal-only modes. The throttle lets you ride without pedaling, while PAS provides varying levels of motor assistance based on your pedaling input and the speed sensor.
Using the app and speed controls
You can manage the maximum speed and other settings through the companion app, and the advertised maximum is 28 mph. You should check local laws on e-bike classifications and speed limits before unlocking higher speeds, since regulations vary by region.
