Almost four years of development, experience from product design at Simplon and DT Swiss as well as feedback on prototypes in real time: this is what goes into the lightweight children's bikes from the Austrian manufacturer "Woom", which also scores with a budget-friendly sales model. A former top Swiss mountain biker is responsible for the branch in this country.

An aluminum frame, a carefree, clean Gates belt instead of a chain and genuine lightweight construction with a total weight of 5.9 kilograms: this is how the children's bike speedsters from "Junior" present themselves. These bikes for youngsters were developed by a Zurich-based bike manufacturer and are now also available from specialist retailers.

Want to really spoil the kids at Christmas? The 20-inch fat bike from English manufacturer Genesis should do the trick. The orange racer with the extra-thick tires is sure to make children's eyes light up under the Christmas tree - and will probably also draw envious glances from their peers.
