TWENTYSEVEN5 E-Power PRO the super light 27.5 inch children's e-bike

That's cool - even if the kids get bigger, they can ride a super-light e-bike that stands out from the competition with a total weight of only 13.6 kg. Up to a body height of approx. 1.75m, the TWENTYSEVEN5 is now the first choice, especially since it rides like a normal bike even without motor support.
