Our take on the TST 750W Peak 1500W Motor 20" x 4" Fat Tire Electric Bike

The TST is a 20-inch fat-tire electric bike built around a 750W motor that peaks at 1500W. The 4-inch-wide tires give it traction on sand, snow, gravel and rough pavement, and the 20-inch wheel size keeps it compact and easy to store. It suits riders who want a small, torquey bike for mixed surfaces rather than a long-distance commuter. Against typical 20-inch fat-tire rivals, the motor is on the strong side; the trade-off is weight and, at this power level, a shorter range than lighter hub-motor bikes.

Questions and answers

Is the 750W motor enough for hills?

A 750W hub motor with a 1500W peak is strong for a 20-inch bike and handles moderate hills well. Long, steep climbs will still work the motor and battery hard, especially with a heavy rider.

What surfaces are the 4-inch fat tires good for?

They are made for sand, snow, gravel and dirt, where the wide contact patch adds float and grip. On smooth pavement they roll slower and feel heavier than narrower tires.

Is a 20-inch fat-tire e-bike good for commuting?

It works for short commutes and errands, and the small wheels make it easy to store. For long daily distances, a larger-wheel bike with narrower tires is usually more efficient.

How does it compare with a 26-inch fat-tire e-bike?

The 20-inch version is more compact and easier to store, and the smaller wheels feel quicker to steer. A 26-inch fat bike rolls over obstacles better and is more stable at speed, but takes up more space.

What should I check before buying?

Confirm the battery capacity and rated range, the bike's weight, and whether it has any suspension. Those details decide how it rides and how easy it is to carry.
