TECHNICAL INFORMATIONS

A unisex sport bike

Available in a variety of sizes (XS: 1.45 m to XL: 2.00 m), the CGF frame is lightweight, comfortable, and versatile.

S: 1.55 m to 1.64 m
M: 1.65 m to 1.74 m
L: 1.75 m to 1.84 m

Front shock absorber

The 80 mm Suntour XCT front shock absorber is designed for rugged pavements, helping beginners easily cope with sporty bike rides. Mechanical springs are designed to be reliable and easy to maintain.

Transmission system

3 x 7 speed sprocket, 21 speed
Three-chain sprocket wheel (22/32/42 teeth) + grease protection -
Microshift front derailleur
Microshift rear derailleur
- with speedometer Microshift hand shif lever
- 7 gears, 14 to 28 teeth Shimano sprocket

Horizontal / handle / handle

The ST 100 sport bike has a 10° angled handle for a comfortable, higher operating position and is easy to operate.

Saddle: Comfortable

The stable seat is fixed to prevent movement during riding. In addition to safety, comfort is also a top priority for us. This sport bike features a unique wider Ergofit seat for the hammock shape. The flexible steel seat tube facilitates height adjustment of the seat and is 350 mm or 400 mm in length (according to the size of the bicycle). The reduced 27.2 mm diameter gives the seat a natural flexibility, higher than the standard.

27.5-inch wheels and tires for dry floors: Are you ready?

Don't worry about obstacles when slowing down: small stones, cracks, small holes, and bumps on the road. The ST 100 bike wheel is durable and has a 27.5-inch double-layer 28 spoke rim that is suitable for beginners to ride on dry roads. The Dry 27.5 x 2.0 tire is more suitable. The circular center area provides excellent performance and the side lugs provide good grip when cornering.

Convenient bike transportation and storage

Considering that you may need to transport or store your car in a limited space (car trunk, porch, etc.), we have equipped it with a front-wheel quick release. The rear wheel of the car has a fixing nut that reduces the risk of being stolen. To remove the rear wheel, you need a wrench.

Not bad a bike for the price. Wish gear changes was a bit smoother, sometimes the chain doesn't catch the gear proper unless I turn the gear dial back and forth.
