The Andsky Gravita LS is a fat tire, full suspension electric bike designed for riders seeking a versatile and budget-friendly eBike option. This review covers everything from its technical specifications to real-world performance, helping prospective buyers make an informed decision. With features such as a 750W motor, hydraulic brakes, and multiple riding modes, the Gravita LS promises a blend of power and comfort at an affordable price point.

Key Specifications of the Andsky Gravita LS

The Gravita LS is equipped with a 48V, 750W rear hub motor capable of delivering up to 1300W peak power and 90 Newton meters of torque. It features a seven-speed Shimano transmission system with a thumb shifter and a 48-tooth chainring, facilitating smooth gear changes across various terrains.

Battery and Range

This eBike includes a 48V 20Ah battery integrated discreetly into the down tube, providing a capacity of 960Wh. Charging time ranges between 6 to 7 hours using the supplied 3-amp charger. The manufacturer claims a range of 50 to 80 miles on a single charge, depending on conditions and riding style.

Frame and Suspension

The bike comes with a full suspension setup:

• Front suspension: 40mm travel spring fork by L&S, preload adjustable and lockable.
• Rear suspension: Hayeway shock with 50mm travel.

This combination aims to absorb bumps and provide a comfortable ride over mixed terrain.

Tires and Brakes

The Gravita LS sports 26×4-inch VROS Vevel City tires with steel reinforcement and a multi-terrain tread, designed for stability on sand, trail, and urban surfaces. Hydraulic RSX two-piston brakes with 180mm rotors offer reliable stopping power for a bike of this size and weight.

Weight and Payload

The bike weighs approximately 92.6 pounds and supports a maximum payload capacity of 500 pounds, accommodating a wide range of rider sizes and cargo.

Size and Color Options

Available in one frame size suitable for riders between 5’7” and 6’5”, the Gravita LS offers four color choices: white, orange, red, and black. The overall bike length is 79.5 inches with a 20-inch standover height. The adjustable stem and seat height (ranging from 34.9 to 39.4 inches) allow customization of rider position.

Modes and Controls

By default, the bike is shipped as a Class 2 eBike, with a maximum speed of 20 mph using throttle or pedal assist. However, it can be unlocked to:

• Class 1: Pedal assist only, up to 20 mph, no throttle.
• Class 3: Pedal assist only, up to 28 mph, no throttle.
• Class R (Race/Unrestricted): Throttle and pedal assist operate up to and beyond 28 mph.

These modes can be toggled through the advanced settings on the bike’s control panel.

Control Interface

The left handlebar houses the control pad with buttons for power, mode selection, pedal assist adjustment (+/-), turn signals, horn, and headlight control. The right side features a full twist throttle, rear brake lever, and a seven-speed shifter.

Display

The full-color display shows battery voltage, speedometer, pedal assist levels, class mode indicator, trip data, average and max speed, and odometer. It includes a USB-C port for device charging.

Riding Experience and Performance

The throttle is full twist, preferred by many riders for comfort, and is responsive across the five pedal assist levels. The cadence sensor controls pedal assist engagement, with no ghost pedaling observed during tests.

Speed and Acceleration

In Class R mode, the Gravita LS achieves speeds of up to 32 mph on flat terrain, slightly exceeding the manufacturer’s claims. Acceleration is smooth and manageable, with no abrupt power delivery.

Suspension and Comfort

On-road and moderate off-road testing showed the front suspension performs adequately, smoothing out bumps and rough patches. However, the rear suspension’s effectiveness is limited, providing minimal shock absorption. The stock saddle is firm, which may impact comfort on longer rides but can be upgraded.

Handling and Stability

The fat tires provide excellent traction and stability on sand, gravel, and pavement. The bike handles well in various conditions, though its weight makes it feel heavy when pedaling without power.

Battery Life and Range Considerations

Real-world testing suggests the Gravita LS delivers approximately 20 to 25 miles of range under mixed riding conditions, including throttle use and moderate pedal assist. Voltage sag was observed under load, and battery indicators fluctuated, which may cause range anxiety for some riders.

To maximize range:

• Use lower pedal assist levels.
• Avoid excessive throttle use.
• Maintain moderate riding speeds and gears.

Hill Climbing and Terrain Capability

The bike struggles with steep inclines despite the high torque rating. It climbs a 20° wet, muddy hill slowly, requiring rider effort and patience. Conversely, it excels in sand and flat terrains, where the fat tires provide superior flotation and grip.

Braking and Safety Features

Hydraulic disc brakes provide consistent stopping power:

• 27 feet stopping distance from 20 mph.
• Approximately 45 feet stopping distance from 28 mph.

Front and rear integrated turn signals and bright head/tail lights enhance rider visibility and safety, especially in urban environments.

Additional Features

• Removable battery with lock and key system for secure charging off the bike.
• IPX6 water resistance rating, protecting against heavy water splashes.
• Plastic fenders and pedals, chainring guard, quick-release seat post.
• Rear rack supports up to 55 lbs of cargo.
• Adjustable stem for personalized riding posture.

Pros and Cons

Pros:

• Competitive price for a full suspension fat tire eBike.
• Adjustable class modes for versatile speed control.
• Hydraulic brakes and front/rear turn signals are rare at this price point.
• Comfortable riding position with adjustable stem and seat height.
• Robust 960Wh battery with decent range potential.
• Full twist throttle offers intuitive power control.

Cons:

• Heavy overall weight (92.6 lbs) impacting manual handling.
• Rear suspension underperforms; produces squeaking noise initially.
• Battery voltage readings fluctuate, causing range uncertainty.

Final Thoughts

The Andsky Gravita LS offers a compelling package for riders looking for a budget-friendly fat tire full suspension eBike with advanced features like hydraulic brakes, turn signals, and multiple speed class options. While it may not excel in hill climbing or rear suspension performance, it delivers solid value for urban commuting, trail riding, and beach traversing.

Its robust motor, large battery, and customizable controls make it a versatile choice for riders between 5’7” and 6’5”. Potential buyers should consider upgrading the saddle and monitoring battery indicators carefully to manage range expectations.

Overall, the Gravita LS stands out in its price category by combining power, comfort, and safety into a single package, making it a practical eBike for recreational and utility use.
