Who it fits

Key specs explained for this bike

Frame Material: Steel

You will notice a solid feel when pedaling, making it a reliable choice for daily commuting or casual trail riding without worrying about frame flex.

Suspension Type: Dual Full Suspension

The bike features shock absorbers on both the front fork and the rear. This dual setup absorbs bumps from dirt, gravel, and uneven paths. It smooths out the ride, reducing fatigue on your hands and back. This is ideal for riders who want comfort on rougher trails or city streets with potholes, compared to rigid frames that transmit more vibration.

Number of Speeds: 21-Speed

You get a 21-speed drivetrain controlled by a grip shifter. This allows you to easily switch gears for different slopes and speeds. Simple operation helps you tackle hills or maintain pace on flats. It is sufficient for mixed-terrain riding, offering enough range for most recreational riders without the complexity of higher-end electronic shifting systems found on premium mountain bikes.

Brake Type: Mechanical Dual Disc Brake

Both wheels are equipped with mechanical disc brakes for stopping power. This system offers reliable braking in various weather conditions, including wet or muddy trails. The mechanical design is straightforward, making it easier to maintain and adjust compared to hydraulic systems.

Suspension is handled by dual shock absorbers on the front fork and rear parallel bars. This full suspension layout aims to soften bumps on dirt, trails, and gravel.

A brief adjustment of the brakes and gears is required before riding. This design prioritizes straightforward upkeep and accessible assembly for new owners.

Before you buy this bike
