The core of our children's and youth bikes is the extremely light and ergonomic triple-butted aluminum frame. The tubes have three different wall thicknesses, which significantly reduces the frame weight. The GRINDER SL PURE 14 is a real small mountain bike. 14 inch children's bicycles are suitable for children from about 4 years old or a stature of about 100 cm. At this age, the most important thing is to train motor skills and balance to further evolve into confident little cyclists. The brake levers are specially designed for small children's hands, so that the V-brakes can be operated with confidence.This way your offspring can brake safely. Also available as a 14 inch version.
