3 wheels - the front wheel can swivel or lock (12 inch wheel filled with air). The 2 back wheels are 16 inches (they can quickly pop off if you need). Holds up to 75 lbs. full harness to keep your little one secure. Huge canopy for shade with window so you can see inside (or cover). Two cup holders + pocket that zips for phone or keys. One foot break that can be pushed up or down. Spacious storage underneath. Jogging strap to be worn around wrist. Seat reclines. Glides and moves super well, I’ve enjoyed it! No issues, we are just moving out of the country and can’t take it with us.
