Guardian Ethos 20

Shop the Guardian Ethos 20 kids bike with patented SureStop safety braking at The Cycle Zone.

Standard kids' bike brakes rely on a child correctly judging which lever controls which wheel, and grabbing the front brake alone can send a young rider over the bars. Guardian's SureStop system activates both wheels proportionally from a single lever, removing that risk while still teaching proper braking habits.

Frequently Asked Questions

What height or age is the Guardian Ethos 20 suitable for?
Wheel size is a better guide than age for the Guardian Ethos 20 — the most important measurement is your child's inside leg length and standover height, not a birthday. Bring your child into The Cycle Zone and we'll size them properly against the Guardian Ethos 20 and similar models so you get a bike that fits now rather than one they'll grow into eventually.
Will the Guardian Ethos 20 last as my child grows, or will we need to size up soon?
Like most kids' bikes, the Guardian Ethos 20 has a reasonable amount of adjustment in the saddle height and, on most models, the handlebar reach, which buys a bit of extra time before a full size change is needed. That said, kids' bikes are generally sized for a specific height range rather than "grown into," so expect to move up a size within a year or two of steady growth.
Does the Guardian Ethos 20 come with a warranty?
Yes, the Guardian Ethos 20 is covered by Guardian Bikes's standard frame and component warranty against manufacturing defects. The Cycle Zone also carries out a full pre-delivery inspection and build on every kids' bike we sell, so it arrives properly assembled and safety-checked, and we're on hand to help with any warranty queries afterwards.
