Overview
This TST fat tire ebike runs a 1500W peak motor with 90 N.m of torque and a 48V 15Ah removable battery that can be doubled to 30Ah for extended range. The reported bought_past_month figure of 1500 marks it as a high-volume seller in this batch, rated for 60 to 100 miles depending on configuration and mode.
Unlike some competitors in this batch, TST states a specific torque figure of 90 N.m rather than only a peak wattage number, along with a 35 degree slope rating. The bike ships with full suspension and dual mechanical disc brakes, and it carries UL 2849 certification through SGS testing. One reviewer's real-world speed test came in noticeably below the advertised top speed, worth weighing against the otherwise positive review set.
- 20x4 inch puncture-proof tires with full suspension
- 360 degree LED lighting: headlight, brake light, turn signals
- Three modes: pure electric, pedal assist, and standard pedal
- 6-month warranty with 24-hour support response
Who it's for
Fits commuters and casual trail riders who want a fat tire ebike with a large review base backing up comfort claims. Buyers chasing the full advertised top speed should read the mixed feedback on that point first.
What buyers say
From Amazon customer reviews.
Most reviewers described the ride as fun, comfortable and long-lasting on battery, with fat tires praised for stability on both trails and pavement. One buyer measured a real top speed of about 23 mph against an advertised 28 mph, a gap worth noting against the otherwise positive feedback.

Performance notes
The 1500W peak motor with 90 N.m torque is rated to climb 35 degree slopes, and the 48V battery reaches full charge in about 5 hours per the manufacturer, with pure electric mode covering over 60 miles. One reviewer measured a real top speed of about 23 mph against an advertised 28 mph in full pedal-assist, gear 7, so treat the top-end speed claim with some caution even though range and comfort held up well in feedback.
