Returning home this week, he is having difficulty sleeping and is taking a lot of medication for pain.
He said he found it hard to believe it was possible for cars to hit cyclists on the main road.
"It's unbelievable cyclists can get hit on an 80km/h zone - it's ridiculous. There's a massive amount of people cycling these days, and it's just off-putting. I'll probably never cycle again on the road, it was very traumatic."
Mr Phillips' mother, Clive real estate agent Pauline Bowden, was also left shaken by the incident, saying it was "a bit of a heart-stopper" when a police officer appeared at the door with her son's mangled bike.
"Drivers need to realise how fragile cyclists are and, first and foremost, are people," she said.
On Tuesday evening, a 31-year-old woman was knocked off her bike on the same stretch of road. She was travelling towards Hastings when a car pulled out of Williamson Rd and struck her. The driver of the car had stopped at the stop sign, looked right, and pulled into the traffic, not seeing the cyclist.
Police constable Wayne Stewart said it was the fourth accident he had attended in the past three years in the region in which a driver had not seen a cyclist.
The cyclist was taken to Hawke's Bay Hospital and discharged later that night.
