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.

Saddle: Comfortable

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.

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

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.
