The Tesway X9 Ultra electric bike is a high-output, dual-motor model built for experienced riders seeking all-wheel-drive traction, strong hill-climbing support, and extended riding capacity. Its 60V dual-motor system produces up to 4,000W of combined peak output and 240 Nm of torque.
Full suspension, 26 × 4-inch fat tires, and four-piston hydraulic disc brakes support controlled riding across hills, gravel, loose surfaces, and uneven terrain. The X9 Ultra is considerably heavier and more powerful than a conventional electric bicycle, so riders should account for its acceleration, braking distance, storage needs, and low-speed handling.
Speed, range, and performance figures come from manufacturer testing and are not guaranteed in everyday use. Actual results depend on the selected battery, motor mode, rider and cargo weight, speed, pedal-assist level, throttle use, terrain, elevation, wind, temperature, tire pressure, battery condition, and maintenance.
The listed output and maximum off-road speed may exceed common US e-bike class limits. Check state and local requirements covering public roads, bike lanes, parks, trails, registration, licensing, insurance, safety equipment, and private-property use before riding.

Dual-Motor AWD Performance
The dual-motor system provides power to both wheels, helping maintain traction while climbing hills or riding across loose and uneven surfaces. The motors have a combined rated output of 2,400W and can produce up to 4,000W of peak output.
Tesway lists up to 240 Nm of torque, giving the X9 Ultra strong low-speed pulling power and acceleration. Riders can select suitable drive and assistance settings based on the terrain, available traction, and desired battery use.
All-wheel drive does not remove the risk of wheelspin or loss of control. Acceleration should be applied gradually on wet pavement, loose gravel, sand, snow, and steep surfaces.
Speed and Rider Control
Tesway lists a maximum speed of up to 43 mph, with acceleration from 0 to 31 mph in approximately eight seconds under manufacturer test conditions.
Actual speed varies with battery charge, rider weight, terrain, wind, tire pressure, motor mode, and bike settings. Higher speeds require longer stopping distances and faster rider reactions.
New owners should become familiar with the throttle, motor modes, brakes, steering, and bike weight at lower speeds before using higher-output settings.
Battery Options
The X9 Ultra is offered with 60V 25Ah and 60V 30Ah battery options. The 30Ah version stores more energy and is intended to provide greater potential range than the 25Ah version.
The detailed manufacturer specifications list the following maximum figures for the 60V 30Ah configuration:
- Up to 120 miles using pedal assistance
- Up to 100 miles using throttle-only operation
These are manufacturer-listed maximums achieved under specific test conditions. They should not be applied automatically to the 25Ah version.
Actual riding distance may be considerably lower with frequent dual-motor use, higher speeds, strong acceleration, hills, heavy loads, low tire pressure, cold temperatures, or throttle-only riding.
Charging
The manufacturer specifications list a 60V 3A charger and an approximate charging time of seven hours.
Charging time can vary with the selected battery capacity, remaining charge, temperature, battery condition, and charging environment.
Charge the battery in a dry, ventilated location using the supplied or manufacturer-approved charger. Inspect the battery, charging port, cable, and charger housing before each use.
Full Suspension
The X9 Ultra uses a hydraulic front fork and rear suspension to reduce vibration and absorb impacts from rough roads, gravel, and uneven terrain.
Full suspension can improve tire contact, comfort, and rider control, but it does not make the bike suitable for every jump, drop, trail, or technical mountain-bike route.
Suspension components should be adjusted for the rider, total load, and riding conditions and inspected regularly for looseness, leaks, or damage.
Fat Tires and Handling
The 26 × 4-inch fat tires provide a broad contact area for traction and stability across mixed surfaces.
Their size, combined with the long frame and approximately 106 lb bike weight, gives the X9 Ultra a more substantial feel than a standard mountain bike. Riders should allow extra space when turning, braking, parking, and moving the bike by hand.
Tire pressure should be adjusted within the manufacturer’s approved range. Pressure that is too low can increase rolling resistance, reduce range, and make handling less predictable.
Brakes and Gearing
The bike uses four-piston hydraulic disc brakes with 180 × 2.3mm front and rear rotors. The four-piston calipers and thicker rotors provide braking support appropriate for the bike’s power, weight, and potential speed.
A Shimano 7-speed drivetrain provides gearing for climbing, cruising, and pedal-assisted riding.
Brake pads, rotors, hoses, tires, and drivetrain components should be checked regularly. Any loss of braking power, unusual noise, fluid leakage, or rotor damage should be addressed before riding.
Display, Lighting, and Security
A full-color LCD provides speed, battery, mileage, assistance, and ride information. NFC functionality allows the bike to be unlocked using the supplied NFC cards.
The X9 Ultra also includes a 900-lumen headlight with an integrated horn. Lighting improves visibility but does not replace reflective equipment, protective clothing, or compliance with state and local lighting requirements.
Size, Weight, and Payload
The manufacturer lists the bike weight at approximately 106 lb and the maximum payload at 400 lb.
Payload includes the rider and any cargo or accessories carried on the bike. Staying below the listed limit does not guarantee unchanged braking, handling, suspension performance, or range.
The bike’s weight should be considered when planning:
- Indoor storage
- Stair access
- Vehicle transport
- Maintenance stands
- Hitch-mounted bike racks
- Loading and unloading
Any transport rack must be rated for the bike’s full weight.
Water Resistance
The X9 Ultra carries an IPX6 water-resistance rating. This indicates resistance to water exposure under specified test conditions, but it does not make the bike waterproof.
Avoid submerging the bike, pressure-washing electrical components, or exposing it to prolonged heavy rain. Allow the bike and charging connections to dry fully before charging.
Recommended Use
The Tesway X9 Ultra may suit:
- Experienced high-output e-bike riders
- Hills and demanding mixed-surface routes
- Riders who want selectable dual-motor traction
- Long recreational rides
- Suitable private-property riding
- Permitted off-road areas
- Riders comfortable handling a heavy, powerful bike
It may not suit beginners, riders who frequently carry a bike upstairs, buyers with limited storage, or anyone seeking the handling and pedaling feel of a lightweight conventional bicycle.
Before You Order
Choose the 25Ah or 30Ah battery carefully and review the specifications attached to the selected variant. Confirm the current package contents, battery capacity, rider fit, bike dimensions, delivery arrangements, and local-use requirements before purchase.
Check applicable state and local regulations before riding. Depending on the location and bike settings, registration, licensing, insurance, protective equipment, or restricted-use conditions may apply.
Frequently Asked Questions
Is the Tesway X9 Ultra legal for public-road use?
Its listed peak output and maximum speed exceed the limits commonly associated with Class 1, Class 2, and Class 3 e-bikes.
Its legal status depends on the selected settings, equipment, and laws where it is used. High-power or high-speed operation may be restricted to private property or specifically approved riding areas.
What is the difference between the 25Ah and 30Ah batteries?
The 30Ah battery stores more energy than the 25Ah option and may provide a longer riding range.
It may also cost more and take longer to charge. Actual range with either battery depends on motor use, speed, terrain, rider weight, cargo, temperature, tire pressure, and riding style.
Can I expect 120 miles from both battery options?
No. The detailed manufacturer range specification is associated with the 60V 30Ah version.
The 25Ah battery has less energy capacity, so buyers should not assume it will provide the same maximum range.
What is the throttle-only range?
Tesway lists up to 100 miles of throttle-only range for the 60V 30Ah configuration under manufacturer test conditions.
Actual throttle range may be much lower when using both motors, riding at higher speeds, climbing hills, carrying heavier loads, or riding in cold or windy conditions.
Why does the X9 Ultra use four-piston brakes?
Four-piston calipers apply braking pressure across a larger pad area and can provide stronger, more controlled braking for a heavy and powerful bike.
The braking system must still be correctly adjusted, bedded in, inspected, and maintained.
Does all-wheel drive improve traction?
Driving both wheels can improve traction during acceleration and climbing, particularly on loose or uneven surfaces.
It cannot prevent skidding, wheelspin, or loss of control. Riders should adjust speed and motor output to suit the available grip.
Can the X9 Ultra be ridden in rain?
The bike is listed with an IPX6 water-resistance rating and may tolerate ordinary splashes and some rain exposure.
It should not be submerged, pressure-washed, or left exposed to prolonged heavy rain. Electrical connections should be dry before charging.
How much does the Tesway X9 Ultra weigh?
The manufacturer’s US specifications list the bike at approximately 106 lb.
Consider this weight before purchasing a transport rack, carrying the bike upstairs, loading it into a vehicle, or storing it indoors.
What is the maximum payload?
Tesway lists a maximum payload of 400 lb, including the rider and anything carried on or attached to the bike.
Added weight can affect acceleration, range, braking distance, steering, and suspension performance.
Who should buy the Tesway X9 Ultra?
The X9 Ultra is intended for experienced riders who understand high-output acceleration, heavy-bike handling, braking requirements, protective equipment, maintenance, and local legal restrictions.
It is not designed as a lightweight beginner commuter or a conventional mountain bike.
