The complainant in the case, who was also riding a motorbike, suffered a broken femur which had to have a metal rod inserted, damage to his kneecap, and also had a metal plate inserted into his tibia.
Bass was said to have suffered a fractured vertebrae.
A pre-trial review will be held, via video link, on June 15.
High Bailiff Jayne Hughes accepted summary court jurisdiction.
