It has emerged the driver of the Land Rover Freelander towing the caravan involved in the A63 tragedy may have pulled-up close to South Cave after noticing a puncture.
A 65-year-old cyclist taking part in a time trial on the A63 died when he rode into the stationary caravan on Friday morning.
A photograph of the crash scene, taken by the Mail shortly after the accident, shows a flat back tyre on the caravan.
A Humberside Police spokeswoman said: "At the time of the collision it is believed the Land Rover and caravan were stationary in lane one of the A63 and the cyclist rode into the rear of the caravan."
The cyclist was from Selby in North Yorkshire.
Riders from across the country travel to East Yorkshire to take part in time trials on the A63, where a new British 10-mile record – 17 minutes 45 seconds – was set last August.
Experienced cyclist Ed Neilson, manager of Cliff Pratt cycle shop on Spring Bank, Hull, says the cycling community has been left deeply shocked and saddened by the tragedy.
Mr Neilson often takes part in time trials organised by various cycling groups on the A63, although he was not participating on Friday morning.
He said: "It's one of the fastest courses in the country – that's what brings people to the area. Time trials are all about speed."
Giving an indication of the speed cyclists can potentially reach on the flat A63, Michael Hutchinson, of London, took the course record last summer averaging a speed of 33.8mph.
Visibility on the relatively straight section of the A63 was good at the time of the accident and the cyclist community is understood to be mystified why the cyclist failed to see the caravan at the side of the carriageway.
Mr Neilson said: "I am not saying this is what happened but, for whatever reason, this cyclist has not seen the caravan at the side of the road.
"Cyclists used to ride 'heads down'.
"But the younger generation of cyclists tend to ride 'heads-up' these days – helmets are designed in such a way that they are more aerodynamic when the wearer's head is up."
About 100 cyclists were taking part in the race organised by Hull City Road Club, which is governed by Cycling Time Trials.
A spokesman for Cycling Time Trials, the sport's national governing body, insists the race was safe and well-organised, despite criticism from drivers for holding it on one of the busiest weekends of the year.
Meanwhile, a second cyclist died on East Yorkshire's roads over the Easter weekend.
As reported here on Tuesday, officers say the latest victim, 46-year-old Peter Finch from Hull, had been negotiating busy Derringham Bank roundabout, where Willerby Road and Spring Bank West meet in west Hull, when he was struck by a black Renault Clio.
Mr Finch suffered serious head injuries in the crash at about 4pm on Sunday and was taken to Hull Royal Infirmary, where he died on Monday.
Roads policing Inspector Mark Hughes, investigating the second tragedy, said: "This is a busy roundabout junction in Hull with both motorists and pedestrians in the vicinity and I am sure there will have been people around at the time who witnessed this incident.
"I would urge anyone who saw the collision or who thinks they may have seen either the Renault Clio being driven immediately prior to the collision, or the cyclist, to contact us."
A 29-year-old man arrested in connection with Sunday's crash has been released on police bail pending further inquiries.
Witnesses to both accidents are asked to call police on 101.
