Dashcam footage shows the moment David Crawford, 59, was knocked off his bike, and the aftermath as he was dragged hundreds of metres under a van and left for dead by the side of the road on the A38 near Plymouth, Devon.
He was "deliberately targeted" by a rival Bandidos gang who were blood-thirsty for revenge, prosecutors argued during a trial.
Three defendants - Benjamin Parry, 42, Chad Brading, 36, and Thomas Pawley, 32, - were all cleared of murder but convicted of manslaughter.
And the trio returned to court today (Fri) where Parry was jailed for 12 years, while Brading and Pawley were sentenced to four years.
