Now that I've gotten my Wheel Stop I can see why the 46" limitation even tho the tray is 9" longer. In the Wheel Stop storage position they designed it so the spool will fit nicely between the folded down rack arms. This forces the front wheel to be located further away from the tray edge than if the bike were centered. This is an issue even for my <46in wheelbase medium size Vado EQ. First picture shows how the bike is center mounted when not using a wheel stop. 2nd pic shows how the Wheel Stop moves the bike towards the rear wheel tray edge. In the case of the EQ fenders, it means the 1up clamp arm will not fit over the fender taillight. While the clamp arm can be adjusted to clamp onto the tire at the 9 o'clock position, this puts the end of the control arm quite a bit outside the width of the car and I'd be uncomforable driving around like that. 3rd pic shows foam added to move the wheel forward. Rear rack arm will clear fender light and can be snugged down closer to where the fender/rack support strut will help support.
4th pic shows Large Tero with 650B wheels when not using a wheel stop. 5th picture shows using a large piece of foam to move the wheel forward. 6th picture shows foam rotated to smaller dimension when used with a 29er wheel. I'd probably add a cinch strap around the wheel stop, foam and wheel for longer drives just for the additional securement.
Other bikes I've tried <46 in wheel base and no fenders fit fine - no issues. Wheel Stop will be great for those to help stabilize the bike.
