Who it fits

Key specs explained for this bike

Frame Material: Aluminum alloy

This frame construction offers a balance of strength and low weight. At 33 lbs, the bike is easier to lift and maneuver than heavier steel models. The material resists rust, which is useful for outdoor storage. You get a sturdy ride that handles trail vibrations without adding unnecessary mass to the overall package.

Number of Speeds: 3x7-speed

This setup provides 21 total gear combinations using a Shimano rear derailleur. You can switch between three front chainrings and seven rear cogs. This range helps you tackle steep climbs and maintain speed on flat roads. It offers reliable shifting for beginners who need simple, effective gear changes without complex electronics.

Brake Type: Mechanical disc

Mechanical disc brakes use a cable to squeeze pads against a rotor. They deliver strong stopping power in rain, mud, or dirt. Unlike rim brakes, they do not wear down the wheel edge. This consistency helps you control your speed safely on varied terrain, making them a practical choice for all-weather riding.

Suspension Type: Suspension fork

The front fork absorbs shocks from roots and rocks. It includes a lockout feature to stiffen the fork for efficient climbing on smooth surfaces. This setup reduces fatigue on rough trails while allowing you to pedal harder on flats. It is a key component for comfort on uneven ground compared to rigid forks.

Tire Width: 2.10"

These tires provide a balance between rolling speed and traction. The 2.10-inch width grips dirt roads and pavement effectively. They absorb minor bumps better than narrow road tires. This width is suitable for casual trail riding, offering stability without the high rolling resistance of much wider off-road tires.

Aluminum Frame and 24-Inch Wheels

The frame is built from high-grade aluminum alloy. According to the listing, this material keeps the bike lightweight at 33 lbs while remaining sturdy. The 24-inch wheels and 2.10-inch tires are designed for dirt roads and pavement. This setup offers good traction for trail adventures or daily commutes.

The geometry includes an adjustable seat post. It fits riders between 5 feet 5 inches and 6 feet 5 inches tall. This range targets tall men and women. The blue finish on the AIVA-EXPLOPER24 model is a standard aesthetic choice that does not affect performance.

Controls center on a 3x7-speed Shimano gear system. This provides seven rear speeds for smooth shifting on climbs and flats. Mechanical disc brakes are used for stopping. They offer more power than rim brakes and stay stable in rain, mud, or dirt. The suspension fork absorbs shocks from roots and rocks. It also has a lockout feature to improve climbing efficiency. The bike arrives 85% assembled with basic tools, making setup quick for beginners.

Setup and everyday use guide

Assembly is straightforward because the bike arrives 85% pre-assembled. You receive clear instructions and basic tools to complete the final steps. This reduces setup time significantly, which is helpful for beginners or first-time buyers who may not have extensive mechanical experience. The ergonomic design includes an adjustable seat post, allowing you to customize the fit for your height. The listing specifies that this adjustment range accommodates riders between 165 and 195 centimeters, or roughly 5 feet 5 inches to 6 feet 5 inches. This makes the bike suitable for tall men and women seeking a proper fit without needing extensive professional adjustment.

For daily use, the 3x7-speed Shimano gear system provides reliable performance across various terrains. The seven-speed rear derailleur works with three front chainrings to offer a wide range of ratios. This setup ensures smooth shifting, which helps you manage steep climbs and maintain speed on flat roads. The mechanical disc brakes are designed to deliver consistent stopping power. Unlike rim brakes, these remain stable in wet conditions, mud, or dirt, which is essential for trail riding and daily commutes in unpredictable weather.

The suspension fork absorbs shocks from roots and rocks on trails. It also includes a lockout feature, which allows you to stiffen the fork for more efficient climbing on smooth surfaces. The 24-inch by 2.10-inch tires provide good traction on both dirt roads and pavement, making this bike versatile for mixed-use scenarios.

Before you buy this bike

This model targets riders between 165 and 195 cm tall. You must verify that your height fits this range before purchasing. The adjustable seat post helps, but the frame geometry is fixed. Ensure your local bike shop can service the Shimano 7-speed drivetrain. While the parts are standard, specialized shops may not stock specific SPATIAL components. You will need a helmet and basic tools for minor adjustments. The mechanical disc brakes require periodic pad checks, especially if you ride in wet conditions. This bike sits alongside other entry-level options in Mountain Bikes & Bicycles. It offers a lighter aluminum frame compared to steel alternatives, which aids in maneuverability. However, it lacks the advanced suspension found on higher-end models. Consider this if you prioritize weight and ease of assembly over complex trail performance. It is best for flat to moderate terrain rather than steep, technical climbs.

Check before you buy

• Confirm your height is between 165 and 195 cm.
• Check if local shops service Shimano 7-speed components.
• Verify the 24-inch wheel size fits your storage space.
• Ensure you have basic tools for final assembly adjustments.
