Product Description

The Yasyas 10KW Peak 72V 40Ah Off-Road Electric Bike is a high-output electric dirt-bike platform built around a 72-volt electrical system, large-capacity Samsung lithium battery, full suspension and hydraulic disc braking.

Yasyas markets this model under the 10KW product title, but the manufacturer’s detailed specification describes the powertrain more precisely as a 4KW brushless motor capable of reaching up to 10,000W peak output. For accurate ecommerce and Merchant Center data, those two power figures should remain clearly separated.

The high-voltage drivetrain is paired with a 72V 40Ah Samsung lithium battery. This equals approximately 2,880Wh of nominal battery capacity and is the basis for the manufacturer’s published maximum riding range of up to 120 km under suitable conditions.

Yasyas publishes a maximum speed figure of up to 90 km/h, or approximately 56 mph. Both speed and range are manufacturer-rated maximum values rather than guaranteed results, and actual performance can vary with rider/cargo load, terrain, temperature, battery condition and other operating conditions.

The chassis uses 6061 aluminum alloy, balancing structural rigidity with lower weight than a comparable heavy steel construction.

A full-suspension system is fitted to help isolate the chassis from uneven terrain. Yasyas does not publish the exact fork travel, rear shock travel or damping-adjustment specification on the current product page, so those values should not be invented or copied from visually similar electric motorcycles.

For braking, the manufacturer specifies a hydraulic disc brake system. Exact rotor diameter, caliper piston count and brake manufacturer are not currently disclosed on the official page and should therefore remain unspecified unless confirmed from manufacturer documentation.

The overall design follows a motocross-style electric dirt-bike layout rather than a conventional pedal-focused commuter ebike. Because of its high power and speed capability, the product should be marketed according to the legal classification applicable to the market where it is sold and used.

Motor Configuration

4KW Rated / 10KW Peak

The most important specification distinction is:

Rated Motor Output: 4,000W
Peak Motor Output: Up to 10,000W

Although Yasyas uses 10KW prominently in the product name, the manufacturer’s product description specifically explains that the brushless motor is rated at 4KW with peak power reaching 10,000W.

For structured ecommerce data, avoid entering:

Motor Power: 10,000W Continuous

unless separate manufacturer documentation confirms that rating.

Recommended wording:

4,000W brushless motor with up to 10,000W peak output.

Battery Configuration

72V 40Ah Samsung Lithium Battery

Voltage: 72V
Capacity: 40Ah
Nominal Energy: Approx. 2,880Wh
Battery Chemistry: Lithium-Ion
Cell/Brand Claim: Samsung

The battery capacity is substantially larger than conventional low-power commuter ebikes and supports the manufacturer’s published long-range specification.

Range Configuration

Up to 120 km

Yasyas advertises:

Up to 120 km

or approximately:

75 miles

on a charge.

This should be treated as a maximum manufacturer rating.

Actual range can vary with:

• Terrain
• Rider and cargo weight
• Riding speed
• Acceleration frequency
• Temperature
• Battery age and condition
• Tire pressure
• Elevation
• Surface conditions

GMC-Safe Range Wording

Use:

“Manufacturer-rated range of up to 120 km under appropriate riding conditions.”

Do not advertise:

“Guaranteed 120 km range.”

Speed Configuration

Up to 90 km/h

Yasyas publishes:

Maximum Speed: Up to 90 km/h

Equivalent to approximately:

56 mph

This is a manufacturer-rated maximum performance figure.

For product-data accuracy, avoid implying that this speed is permitted on public roads in every jurisdiction.

Frame Configuration

6061 Aluminum Alloy

The manufacturer specifically identifies:

6061 Aluminum Alloy

as the frame material.

This is preferable to generic wording such as “heavy-duty metal frame” because the exact alloy family is published.

Suspension Configuration

Full Suspension

Yasyas specifies a:

Full Suspension System

for the model.

This means suspension is incorporated at both the front and rear of the chassis.

Unverified Details

The current official product page does not provide reliable exact values for:

• Front suspension travel
• Rear suspension travel
• Fork diameter
• Compression adjustment
• Rebound adjustment
• Rear shock dimensions

Do not add these values from another 72V dirt bike.

Brake Configuration

Hydraulic Disc Brakes

The manufacturer specifies:

Hydraulic Disc Braking System

for this exact model.

Not Officially Published

The exact product page does not currently confirm:

• Rotor diameter
• Caliper brand
• Piston count
• Brake fluid specification

Those should remain omitted unless verified separately.

Battery Energy

A 72V × 40Ah nominal battery configuration corresponds to approximately:

2,880Wh / 2.88kWh

of nominal stored electrical energy.

This can be used as an ecommerce battery-energy specification while keeping the manufacturer’s original 72V 40Ah rating visible.

Performance Configuration

The manufacturer describes this exact platform around three primary performance figures:

Motor: 4KW rated / 10KW peak
Speed: Up to 90 km/h
Range: Up to 120 km

These specifications should remain clearly labeled as manufacturer-rated values rather than guaranteed results.

What’s Included

The official product page confirms the complete electric bike as the primary product but does not publish a sufficiently detailed box-content list.

For an exact listing, safely state:

• 1 × Yasyas 10KW Peak 72V 40Ah Electric Dirt Bike
• Integrated 72V 40Ah battery system
• Integrated motor and controller system
• Full-suspension chassis
• Hydraulic braking system
• Standard installed components

Product Use & Classification Note

This product is significantly more powerful and faster than a typical pedal-assist commuter ebike.

Do not automatically label it:

• UK road legal
• EAPC compliant
• Bicycle-lane legal
• Registration-free
• License-free

unless you have specific documentation supporting those claims for the market where it is sold.

A safer ecommerce classification is:

High-Power Off-Road Electric Dirt Bike / Electric Motocross-Style Bike

Important Product Notes

10KW Means Peak Output

The exact official product title states:

10KW

Therefore use:

4,000W rated / 10,000W peak

throughout the technical specifications.
