Sport On Troublemaker


They designed our Troublemaker for children aged 8-14. In its standard version it will provide everything necessary for safe ride on roads, bike paths and even light off-road terrain. Troublemaker, given its nature, is custom built and can feature virtually any commercially available component, including electric assist. On special request, the bike can also feature a wireless electronic rescue and brake system operated by the parent.


A perverse name yet a precise description of this rascal. This bike was built for younger users to participate in family and social life with their peers.
