What's the difference between the AIROS and ETHOS models?

Great question! Formerly known as Original, our AIROS line is our super-premium, lightest weight, no compromises bike. It's our all-around best and most popular bike. 

Our ETHOS line is the new line we developed with the goal of reaching more families through a slightly more affordable option. It has the same SureStop brakes, the main difference is that it has a steel frame instead of aluminum, making it a couple of pounds heavier than the Guardian AIROS line. 

If you'd like some more info, we made a few short videos explaining the difference for each size:
