Adrian Lovatt, aged 46, from Harrogate, suffered serious injuries to his ankle and arm when he was forced off the B6164 Knaresborough to Wetherby road at around 8.25am on Tuesday 20 September 2011.
He had just passed the roundabout at the junction with the A658 when he was overtaken on a bend by a small silver vehicle carrying three young men. As the car overtook the moped it cut back across its path to avoid a vehicle travelling in the opposite direction.
The actions of the silver vehicle’s driver forced Mr Lovatt to veer to the left to avoid a collision and he fell from his bike after hitting the grass verge at the side of the road.
Despite an earlier appeal the small silver vehicle is yet to be traced and officers are appealing to anyone who can help the investigation to come forward.
Traffic Constable Stuart Holden, of Harrogate Roads Policing Group, said:
Mr Lovatt was seriously injured in this collision. He has had his right shoulder replaced which has limited his movement and he has spent quite some time in hospital.
It is vital to the investigation that anyone who saw what happened on the morning of Tuesday 20 September comes forward and tells us what they saw.
I am particularly interested in speaking to anyone who can help trace the occupants of the silver coloured car.
Anyone who can help the police with their enquiries is urged to contact Tc Stuart Holden, of Harrogate Roads Policing Group, on 0845 60 60 24 7, quoting reference number 12110159729.
