The Oakland Police Department is investigating a solo bicyclist collision that occurred just before 5:00 p.m. yesterday.
The collision occurred in the 3500 block of Dwight Way near the overlook in the Oakland Hills.
Officers responded to the area on reports of a serious injury collision involving a bicyclist. When they arrived, they found an injured individual on the ground. Emergency medical personnel responded, but the adult male was pronounced dead at the scene.
According to witness statements from the preliminary investigation, it appears the solo bicyclist was traveling downhill near the bend when he collided with a guardrail, causing the bicyclist to be ejected from his bicycle.
First responders observed that he was not wearing a helmet at the time.
The Alameda County Coroner’s Office later identified the victim as 44-year-old Luke D. Rivera of Emeryville.

Luke had an English degree from U.C. Berkeley and was currently working on his master’s. “He was a good guy and a great uncle to my daughters. We will all miss him very much,” provided his brother Michael Rivera.
Luke is survived by his brothers and his large, extended family.
Anyone with information is asked to contact the OPD Traffic unit at (510) 777-8570.
Additionally, if any members of the public have videos or photos that could assist with the investigation, they should be sent to cidvideos@oaklandca.gov.
Heartbreaking. Sad for this young man’s family, my condolences. I wonder where his helmet was. Rest in peace Luke Rivera. Glad nobody else was involved.
I will see you on the other side. Rest in peace little bro.
Is this your brother?
Yes.
I was there when your brother passed. I just wanted you to know he did not suffer at all, it was instant. He looked like he had a good ride and anyone who can make it to the top of pano on a fixie must have had a good day!
Apologies this is not really the forum for this but I wanted you to know.

Thanks Chris. It’s been a long time.
Too long brother, miss you, my brother
It’s been too long since last we spoke. Now I must wait to meet again on the other side rest in peace, my brother,
I find myself overwhelmed with the weight of this loss. My heart aches, knowing that my brother Luke, a man who truly lived his life to the fullest, is no longer with us. In all my life, I have never met anyone quite like him. Luke’s energy, his kindness, and his unwavering joy for life left a mark on everyone fortunate enough to know him.
To Michael, and to all those who were touched by Luke’s spirit, I extend my deepest condolences. Luke was a person who left lasting impressions on everyone he met. His presence was a gift—his infectious smile, his laughter, and his genuine care for those around him lit up every room he entered. I will always carry in my heart the memory of his smile, a reminder of his warmth and love.
Luke, you’ll be missed deeply, by every life you touched. Thank you for the memories, for the laughter, and for showing us all what it means to live fully.
Well said. Luke was laid to rest 11/22, I will carry him in the heart for the rest of my days.
