TST Electric Bike for Adults, 20″ Fat Tire, Dual Suspension, 48V 15Ah Removable Battery

Overview

The TST fat-tyre e-bike is designed for riders who want an upright, forgiving ride rather than a race position. Wide 20×4 inch tyres float over cracked asphalt, gravel and grass; dual suspension absorbs what the tyres do not; and the step-through moped stance makes starting and stopping stress-free, which is exactly what newer riders need.

Motor and modes

A 48V 15Ah battery feeds a hub motor with three working modes: throttle only, pedal assist, and pure pedal. Assist levels let you decide how much you want to sweat — full assist for the commute home in the rain, light assist for a weekend cruise. 7-speed gearing handles hills and lets you ride it as a normal bike when the battery is low.

Range and charging

Expect roughly 60 miles of range in economy assist, less in the high setting. The battery removes with a key and charges from any wall outlet in a few hours, so it can live indoors while the bike stays outside.

Comfort and control

Dual suspension front and rear, a wide saddle and swept-back bars make longer rides comfortable. The LCD display shows speed, distance and battery state at a glance, and disc brakes bring the bike down confidently from speed, even fully loaded with a rider and groceries.

Build and safety

It ships almost fully assembled in a certified, safety-tested package, with the electrical system built to regulated standards. Check bolt torque and tyre pressure after the first few rides, as you would on any new bike.

What is in the box

Bike, 48V 15Ah removable battery, charger, keys, pedals, assembly tools and manual.

Who it is for

Commuters who want a comfortable upright ride, beginners who value stability, and riders on mixed city and gravel surfaces.

Good to know

Keep the tyres at the recommended pressure — fat tyres are sensitive to it, and correct pressure noticeably improves range and handling.
