In market, the 12”/14”/16”/20” child bikes all have a one-size frame. However, as children grow and develop, their bikes need to be replaced again and again, resulting in the increase of expenditure and the burden of the environment. Especially for children 135cm-150cm tall, neither the child bikes or the adult ones fit them. GIATEX FIT stretchable design provides the best solution that allows children to adjust the length of the bike frame gradually with their growth, and help them maintain a proper riding posture.

Shorter frame allows children who learn bicycles from scratch to ride like "jogging."

when children get familiar with bikes, they can gradually adjust bike's frame longer to ride from " jogging " to " running ."

Besides, some people do not like to go biking when the weather is too cold, too hot, or when it rains. Given such circumstances, GIATEX FIT can be used as an indoor flywheel for fitness training, providing biking pleasure to the whole family in their own home.
