TST X6 20-Inch Fat Tire Electric Bike with 48V 15Ah Removable Battery

Product Overview

The TST X6 is an adult electric bicycle built around a moped-style frame, wide tires, a removable lithium-ion battery, and front and rear suspension. Public listings for the X6 identify a 20-inch wheel format with 4-inch-wide tires, a seven-speed mechanical drivetrain, and a rear electric hub motor intended to supplement pedal power.

The single-battery configuration uses a 48-volt, 15-amp-hour battery. This capacity corresponds to approximately 720 watt-hours of stored energy. The bicycle is also associated with an LCD display and smartphone app connectivity for viewing and adjusting supported ride information.

The X6 is marketed for a mixture of paved commuting and recreational riding on rougher surfaces. Its fat tires and dual suspension distinguish it from conventional narrow-tire commuter e-bikes. Actual speed, range, climbing performance, and battery endurance vary with rider weight, terrain, temperature, tire pressure, assistance level, and riding conditions.

• Inspect tires regularly for cuts, embedded objects, abnormal wear, and pressure loss.
• Check brake performance before each ride and service worn brake components as necessary.
• Keep the chain clean and apply suitable bicycle-chain lubricant when required.
• Check bolts, pedals, handlebars, wheels, and other assembled components for looseness.
• Store the bicycle and battery in a dry location away from extreme temperatures.

The manufacturer advises matching replacement batteries to the bicycle’s required voltage and model compatibility rather than selecting a battery by voltage alone.

Safety Information

An electric bicycle combines conventional bicycle components with a high-energy rechargeable battery and motor system. Riders should inspect steering, brakes, wheels, tires, and battery attachment before operation and follow applicable helmet and traffic laws.

• Use only a compatible battery and charging system intended for the bicycle.
• Do not charge a battery that is visibly damaged, swollen, leaking, unusually hot, or otherwise compromised.
• Charge lithium-ion batteries away from combustible materials and excessive heat.
• Do not modify the battery pack, charger, controller, motor wiring, or battery connectors.
• Keep braking distance in mind when riding at higher assisted speeds or on loose surfaces.
• Confirm local e-bike rules before operating on streets, trails, bicycle paths, or public land.
• Avoid exceeding the bicycle’s documented load limits.

Public listings for X6 configurations identify UL 2849 testing or certification claims for the electric bicycle system. Certification should be confirmed from the labeling supplied with the specific bicycle because certification can differ among production variants.

Technical Specifications

These characteristics are documented across public records for the specified X6 catalog entry and corresponding X6 configurations. Values that could not be verified consistently across sources, including exact bicycle weight, dimensions, maximum speed, maximum load, and real-world range, are intentionally omitted.

Product History

Public catalog information identifies the X6 as a 2026-model electric bicycle. The model is part of a broader TST lineup containing several moped-style, commuter, cargo, and fat-tire electric bicycles.

Public marketplace records also identify X6 PRO and dual-battery X6-related configurations. These should be treated as separate variants rather than assumed to have identical specifications to the single-battery X6 covered on this page.

Key Features

• Removable lithium-ion battery allows charging either on or away from the bicycle.
• Wide 20-inch fat tires provide a larger contact area than conventional narrow bicycle tires.
• Front and rear suspension are intended to isolate the rider from some surface impacts.
• Seven mechanical gears allow pedal gearing to be adjusted independently of electric assistance.
• Disc brakes provide braking at the wheels.
• A digital display provides access to operating information while riding.
• Smartphone app support adds compatible electronic monitoring and control functions.

Package Contents

Public documentation for X6 configurations identifies the following included equipment:

• Electric bicycle
• Removable battery
• Battery charger
• User manual

Specific accessory bundles can vary by configuration, so additional accessories should not be assumed unless documented with the individual bicycle.

Compatibility

Replacement batteries, chargers, controllers, displays, motor components, brake parts, and other electrical components should be matched to the X6 rather than selected solely by appearance. Matching voltage does not by itself establish electrical or mechanical compatibility.

Tire and tube replacements must match the bicycle’s rim diameter and appropriate tire dimensions. Mechanical replacement components must also match the installed drivetrain, braking system, mounting interfaces, and other relevant dimensions.

The manufacturer’s battery guidance specifically advises verifying model compatibility when replacing a battery.

Frequently Asked Questions

What model is this electric bike?

The bicycle associated with this catalog entry is identified as the TST X6. Model identification should also be confirmed from the label or documentation supplied with the bicycle.

Is the battery removable?

Yes. The battery can be removed from the bicycle, allowing it to be charged or stored separately when appropriate.

Can any 48-volt e-bike battery be used as a replacement?

No. Voltage is only one compatibility factor. Battery dimensions, mounting rails, connectors, controller requirements, current capacity, communication electronics, and model compatibility must also match.

Is the X6 intended only for pavement?

No. Its fat tires and suspension are associated with mixed-surface use. However, trail access and electric-bicycle rules vary by location, and the bicycle’s design does not make every terrain condition suitable or legal.

Does the bicycle require assembly?

Public X6 documentation includes assembly tools and identifies some assembly as part of initial setup. All assembled components should be securely tightened and checked before operation.

Does the bike have mechanical gears?

Yes. The bicycle uses a conventional geared drivetrain in addition to its electric drive system, allowing the rider to adjust pedal resistance for different riding conditions.

How should the battery be stored?

The battery should be kept in a dry environment away from excessive heat, freezing conditions, moisture, direct flames, and physical damage. Manufacturer-specific storage and charging instructions should take priority.

How is the correct replacement tire identified?

Use the dimensions printed on the original tire sidewall and verify rim compatibility. Wheel diameter alone is not enough because tire width and other fit characteristics also matter.

Can the bicycle be ridden without electric assistance?

As a pedal-equipped electric bicycle, it retains a mechanical drivetrain. Pedaling behavior without assistance can differ from that of a conventional bicycle because electric bicycles generally carry additional motor and battery weight.

Does the X6 connect to a smartphone?

Public information for this configuration lists app control. Available functions can depend on the installed display, controller, software version, and mobile application.

What warranty applies to the X6?

TST publishes warranty support for its electric bicycles, but warranty terms can vary by model, component, seller, and date of purchase. The applicable written warranty supplied with the specific X6 should be used to determine coverage and duration.

Buying Considerations

Important points when comparing this model with other electric bicycles include battery capacity, motor configuration, bicycle weight, local e-bike classifications, replacement-part availability, brake design, tire dimensions, suspension, and riding position.

Fat tires provide different handling and rolling characteristics from standard commuter tires. They can suit uneven surfaces but may require more effort when riding without motor assistance and can require less commonly stocked replacement tires.

Advertised riding range should not be treated as a fixed distance. Battery condition, assistance level, rider mass, hills, wind, ambient temperature, speed, stops, and tire pressure can substantially affect the distance achieved from one charge.

Customer Feedback Summary

This section is a generalized summary of publicly available customer feedback and is not a source of verified product specifications.

Public feedback associated with the X6 and closely matched TST fat-tire configurations commonly discusses the comfortable ride provided by the wide tires and suspension, electric assistance on hills, and the usefulness of a removable battery. Ease of basic setup and the bicycle’s moped-style riding position also appear in positive owner comments.

Reported limitations include the size and weight typical of fat-tire electric bicycles, the effort involved in moving the bicycle without motor assistance, and the need to adjust or inspect components after shipping and assembly. Battery range also varies considerably among riders because riding conditions and assistance settings differ.

Because customer reports are subjective and can cover different production variants, they should not be treated as evidence for dimensions, speed, range, motor output, battery performance, or other technical specifications.
