Great first 'adult' bicycle with gears for a child. Light and reliable, it will be easy and comfortable to learn to ride in the park. Condition: good used, fully functional and ready for rides. Key features: 20-inch wheels: an optimal size for children roughly from 6 to 9 years old (height 115-130 cm). Lightweight frame: it is much easier for a child to handle the bicycle and ride up small hills. 7-speed transmission (Shimano Tourney): proven mechanics to master shifting gears. Cube quality: a sturdy branded bike that will last a long time.
