Main highlights

Strong load capacity: the triangular frame and thickened tubes ensure a high load capacity of 150 kg.
SAFE DRIVING It is equipped with front and rear disc brakes, which make the brakes more sensitive and gentle. And its 26 inch tyres have a strong grip and wear resistance, so you can enjoy a safe ride.
PRECISE GEARRING It has precision shifting on the front and rear chainstay, which allows you to accurately shift for different terrain. The precision 21 speed mountain bike helps you adapt to the terrain on the trail and offers you a smooth shifting experience.
HEALTHY LIFE Compared to driving by car, cycling not only strengthens your muscles and bones, but also helps you lose weight effectively and have a healthy body!
Good Cushioning Effect The shock absorbing frame and U-shaped shock absorber fork provide a stronger cushioning effect, which can effectively relieve the pressure on your hands and shoulders caused by intense driving.
ENVIRONMENTALLY FRIENDLY No fuel or gasoline is needed when cycling and no harmful gases are produced while driving. In other words, it also does not incur additional costs and is economical and affordable.
Durable Material The stand is made of thickened high carbon steel, which has high corrosion resistance and bearing capacity, making it very stable and at the same time not easy to be damaged.
COMFORTABLE RIDING It has an ergonomically designed saddle and soft rubber handlebar, so you can ride easily. The comfortable, highly elastic PU saddle ensures that you feel comfortable even after hours of use. The lower stand height (85 cm) improves alignment between the body and bike, making it easier for smaller riders to get on and off.
Adjustable saddle height: the saddle can be adjusted between 80-95 cm, so you can adjust the height according to your comfort.
21 SPEED WHEEL The main wheel has 3 discs and the driven wheel has 7 discs. You can choose whether you want to hang on the different discs of the main and the driven wheel to get 21 different speeds that make your ride easier.
