The latch holding the nose of the Sputnik shut rattles and is flimsy. It can easily open unexpectedly. Since the passenger grab rail is attached to the nose, this can be a bad thing. I removed the mechanism from the inside of the sidecar and replaced it with two latches on either side of the exterior. These dog down securely and don’t rattle at all. I recommend this mod to anyone using the Sputnik sidecar.
