Main highlights

Shimano components: with the 7-speed Shimano derailleur gears with almost seamless transmission, you are equipped for any situation. The particularly grippy disc brake at the back and front provides the necessary control
Risk-free testing: You won't find the perfect bike within 10 minutes. Wouldn't it be much better if the child could really ride outside for a day? No problem with us. We put one more on it and leave the child 60 days to test it extensively. If it is not the right thing, you can return it regardless of the statutory cancellation period without discussion (return costs after the statutory cancellation period bears the buyer).
Quality work: very sturdy aluminium frame for everyday use on the mountain, in the city or at school. With a tyre size of 20 inches and frame size 12 inches, it is suitable for boys or girls, from approx. 125 cm
Full suspension: a full suspension mountain bike has a front fork suspension as well as a frame suspension, so that off-road rides are better cushioned. In addition to the higher riding comfort, a full suspension also pays for safety and driving pleasure: contact with the ground is increased by the frame suspension, which gives the MTB more traction.
Easy to install: handlebars, saddle, pedals, front and rear wheels still need to be mounted. An understandable video of the assembly can be found in the product images and if necessary, our customer service is of course at your disposal.
