This seems to be the only rack that works with the small Pace 500 Step Through. I think they should have been included with the rack. I wish the Planet K.O.K.O. would work, but the stays are too short
Planet Bike Eco Rack Extra-Long Stay: Pair, 15.5"
Gotta have them to mount the Eco rack on the Pace 500. Should have been a choice with the rack rather than an extra purchase. Especially since Aventon knows you must have them for the Pace 500. Had to throw out the short stays that came with the rack. What a waste.
