Our verdict
A lot of spec for the money — 749 W rated, 720 Wh, full suspension, 450 lb — from a lesser-known brand with a short warranty.
Handy riders who want maximum spec per dollar.
Anyone who wants a long warranty and brand support.

Listing check: The spec table lists linear-pull brakes, but the bullets describe disc brakes.

The spec table says 'linear pull' brakes; the bullets describe disc brakes. A dash (—) means the value isn't published anywhere we could verify.
In-depth review
The TST R004 is one of Amazon's fastest-selling fat-tire bikes (500+ a month): a 749 W rated motor (2,000 W peak), a 720 Wh battery, front and rear suspension and 20 × 4 in tires on a 66 lb frame rated for 450 lb.
The catch is support: a 180-day warranty from a third-party seller, a steel frame, and a listing that contradicts itself on brakes. Owners mention loose hardware that needed tightening.
If you're handy with a wrench, it's strong value.
Owner reviews
4.2★ from 421 ratings (81% four or five stars). Owners like the ride and battery; 10% one-star reviews and some loose-hardware complaints.
Fantastic e-bike; watch a YouTube video for the seat, which goes on with the bike upside down.

Smooth ride, good power and the battery covers his daily riding.
— Trenell, Amazon.com
Rides and brakes well, but the hex flange nuts need attention.
