Emergency services, including London's Air Ambulance and Metropolitan Police , were called to the collision between a lorry and a cyclist at just before 9am in South Road, at the junction with St Joseph's Drive.
The male cyclist, believed to be in his 60s, was pronounced dead at the scene.
As part of the vigil, cyclists will leave Ealing Town Hall at 7pm on Friday (November 10) and pedal along Uxbridge Road to arrive in South Road at St Joseph's Drive at 7.30pm, where the fatal collision took place.
A vigil and a minute's silence will then be held.
Anyone and everyone is welcome to attend both the vigil and the cycle from Ealing Town Hall.
The vigil has been organised by Ben Owen, a member of the Ealing Cycling Campaign who says "enough is enough". It is four weeks after a female cyclist died in hospital after sustaining serious injuries when she collided with a lorry in The Broadway, West Ealing.
Ben told getwestlondon : "Enough is enough, our roads are far too dangerous, better infrastructure is needed and on that particular stretch of road which is a busy road.
"Ealing needs to take seriously the needs of its cyclists on its roads today, otherwise we are going to be witnessing more and more tragedies like this one.
"That bit of road is dangerous to cycle on."
He also called for better infrastructure as a priority to safeguard cyclists.
As the police investigation is ongoing, Ealing Council has declined to comment at this time.
No arrests have been made in connection with the incident on Thursday and officers from the Met's Serious Collision Investigation Unit are investigating.
