An ultra-lightweight belt drive, running on the best-in-class wheels, makes sure pedalling is always a breeze for those little legs - always. No grease means there's never any grime building up to make their life harder (as well as no oily stains to make your life harder).  
The drive train is aluminium too, so there are no rusty chainrings to replace. And stretch or wear? These belts last as timing belts in car engines - you're safe.
So that’s free rolling, clean, quiet, durable, rust-free, low maintenance. Low cost of ownership, no discernible loss of performance and no corrosion to hurt resale value. If only it had legendary geometry and market leading finishing kit... Is it any wonder that the Belter 16 reinvented the first bike?
