How this e-bike scores for different riding styles

Compact & Portable
92/100

Folds to 36.6x17.9x31.1 inches in 10 seconds and weighs 55 lbs, making it highly portable for car storage and compact spaces. The foldable design is a primary feature.

Daily Commuting
85/100

With 40 miles PAS range, foldable design, and 25 mph speed, this bike excels for daily commuting. The removable battery and integrated lights add practical convenience for work travel.

Recreational Leisure
80/100

Comfortable for casual rides with front suspension, LCD display, 7-speed gearing, and fat tires. The rear rack adds utility for leisurely trips with cargo.

Off-Road Adventure
78/100

Fat tires, front suspension, 1000W peak motor with 80 Nm torque, and 25-degree slope capability make it capable for trail riding, though single suspension limits extreme off-road performance.

Cargo & Utility
75/100

350 lb weight capacity and included rear rack support moderate cargo hauling. However, at 55 lbs bike weight, the actual cargo capacity is around 295 lbs, suitable for groceries and deliveries.

High Performance
72/100

1000W peak motor and 25 mph speed are respectable but not exceptional for performance enthusiasts. The 36V 7.8Ah battery (281Wh) limits sustained high-power riding.

Our Verdict

The TST Folding Electric Bike delivers impressive value at $540, packing features typically found on bikes costing twice as much. The 1000W peak motor provides strong acceleration and easily conquers steep 25-degree hills, while the fat tires grip well on sand, snow, and trails. The foldable frame is a standout feature, collapsing in just 10 seconds to fit in car trunks or small closets. The included rear rack, full fenders, bright LED headlight, and easy-to-read LCD display add practical value. UL certification on the removable battery ensures safe charging at home or work. The 7-speed gearing and three riding modes let you switch between full electric, pedal assist, or regular biking.

This bike is perfect for city workers who need to fold it up and store it under their desk or in an apartment. The 40-mile range with pedal assist covers most daily commutes easily. Weekend adventurers will enjoy the fat tires and powerful motor for exploring trails and beaches. The 350-pound weight limit means bigger riders or those carrying groceries feel secure. At this price, you get a complete package without needing to buy extra accessories. The quick folding makes it great for people who drive part way to work, then bike the rest.

However, the small 281Wh battery is the biggest weakness - you only get 20 miles using throttle alone without pedaling. The 55-pound weight makes it hard to carry up stairs daily. Only having front suspension means rough roads feel bumpy. The 6-month warranty is short compared to most bikes that offer a year or more. Serious riders wanting long-range trips, top speeds over 25 mph, or advanced features like phone apps should spend more on premium models. But for the price, this bike gives you amazing bang for your buck and does everything most riders need.

What We Like

  • Super affordable at $540 with a powerful 1000W peak motor that climbs 25-degree hills easily
  • Folds down in just 10 seconds to fit in your car trunk, perfect for small apartments
  • Goes 40 miles on one charge when you pedal along, great for daily rides to work
  • Fat tires work on any surface - sand, snow, dirt trails, or city streets
  • Comes with everything you need: lights, rear rack, fenders, LCD screen, and UL-certified battery

What Could Be Better

  • Small battery at only 281Wh means just 20 miles if you only use the throttle without pedaling
  • At 55 pounds it's pretty heavy to carry up stairs or lift onto a bike rack
  • Only has front suspension so bumps in the back can feel rough on long rides
  • Short 180-day warranty is only 6 months, while most bikes come with a year or more
  • Missing modern features like phone app, USB charging port, and cruise control

Standout Features

1000W Peak Motor with 80Nm Torque

Foldable Design (36.6x17.9x31.1 inches folded)
Exceptional portability for a fat tire bike - folds in 10 seconds to fit car trunks, much more compact than standard e-bikes
Fat Tires with Front Suspension
Superior all-terrain capability compared to standard commuter bikes - handles sand, snow, trails, and city streets with confidence

Frequently Asked Questions

Common questions about TST Folding Electric Bike for Adults, 1000W Peak Motor EBike with 36V 7.8Ah Removable Battery, Max Range 40 Miles 25 MPH Electric Bicycle, 20" Fat Tire All Terrain E Bike with Rear Rack

How far can I ride on one battery charge?

You can ride 40 miles if you pedal along with the motor helping you, or 20 miles if you just use the throttle without pedaling. How far you actually go depends on how much you weigh, if you're going uphill, and how fast you ride.

How long does it take to charge the battery?

The battery charges fully in 5 hours when plugged into a regular wall outlet. You can take the battery off the bike and charge it inside your home or office.

How fast does this electric bike go?

The bike can reach speeds up to 25 miles per hour. That's fast enough for bike lanes and getting around town quickly, but not as fast as cars on highways.

Can this bike handle hills and rough trails?

Yes, the strong 1000W motor climbs hills up to 25 degrees steep. The fat tires and front suspension help on bumpy trails, dirt paths, sand, and snow. It works great for most off-road riding.

How much weight can this bike hold?

The bike can carry up to 350 pounds total, including you and anything in bags or on the rear rack. The bike itself weighs 55 pounds, so you have about 295 pounds left for the rider and cargo.
