The children's bike market is similar to the market for adult bikes: it is extremely deep and broad, the selection is large and quite confusing for the uninformed. The choice for parents who want to buy a bike for their offspring is made a little easier by the newcomer Li:On bikes, because the focus here is clearly on visibility, and therefore also safety:

The frame of the Li:On bikes houses a small removable battery in the down tube, which powers a red LED light on the rear triangle that is visible from all sides. At the front, a front light completes the lighting program. To make the lighting easy to operate, you don't have to operate it at all: A motion sensor adjusts the light automatically, and after a pause in motion, the light switches itself off again. All you have to do is ensure that the battery is recharged every one to two weeks with regular use. 

Li:On does not send dedicated mountain bikes into the race; with slightly profiled tires, the bikes can also cope with somewhat bumpy surfaces. With frame sizes of 24 and 27.5 inches, the new children's bike manufacturer is targeting kids from around 7 to 14 years of age.
