What's the difference between the AIROS and ETHOS models?
Great question! 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:
Below are the weights for all of our bikes:
16 inch = 16 lbs
20 inch Small = 18.7 lbs
20 inch Large 6-speed = 21.2 lbs
