Ethic's "New Standard " series is encouraging the scooter industry to follow them in this step forward in the way scooters are designed. For years we've stuck to the same axle size as the original Razor scooter and standard size skateboard bearings in our wheels, bending & snapping our axles and blowing out bearings. Ethic's "New Standard" improves upon this by use of 12mm axle bolts, paired with much bigger bearings and wheels to match. Bigger axles and bearings only mean fewer problems and we're all for the change. Keep in mind that this wheel is larger and wider than your average wheel size so they might not fit on just any scooter.
