Lewis Williams, from Great Bridge, was confirmed dead at the scene in Princes End, Tipton, after being involved in a crash with a car on October 12.
His family and friends gathered on Saturday for a ride out by the Tilted Barrel pub and on Sunday to release balloons at Farley Park.
Cars, trucks, motorbikes and quad bikes were brought to the pub in memory of Lewis.
Lewis had been working at Dove Steel Doors with his father Ray Southall for six months.
Mr Southall said: "It's just shocking really, I can't believe it still.
"He loved bikes and cars, he followed me with that.
"We had a get together on Saturday, friends came with their motorbikes and a few cars as well.
"And his mum and some friends organised a balloon release in Farley Park, it was a good turn out.
"It's just nice to know that a lot of people turned out, if he was here he'd be surprised how many people turned up.
"He was a quiet kid but very loving as well."
The ride out event was organised by Lewis' cousin Ashley Tether, who thanked all the friends and relatives who had supported the family through the difficult time.
Paramedics were at a nursing home in High Street, Princes End, on October 12 when they heard a crash and found Lewis lying in the road outside.
After realising the severity of his injuries, the crew requested back up from two further ambulances, two paramedic officers and a MERIT trauma doctor and critical care paramedic.
At the time, police said they had launched an investigation into the collision – and said the driver of the car involved was helping with their enquiries.
