Charges Filed in Dickinson Crash

YGR has learned that the motorcyclist who struck and killed Ian Dickinson on April 27, 2025, has been charged and arrested.

Wilson Arikita, 62, of Fort Collins, has been charged with vehicular homicide involving reckless driving, a Class 4 felony. A warrant was issued for his arrest last week, and Arikita was taken into custody by the Colorado State Patrol at his home today, nine months to the day after the crash. He is currently being held at the Larimer County Detention Center.

Under Colorado law, vehicular homicide occurs when a person’s driving causes another person’s death because the driver was impaired by alcohol or drugs (not suspected in this case) or was driving in a dangerously irresponsible manner. Reckless driving refers to a conscious decision to operate a vehicle with clear disregard for the safety of others, such as driving far above the speed limit, racing, running red lights, or ignoring basic traffic laws in a way that creates an obvious risk of serious harm or death. The charge is punishable by two to six years in prison, up to three years of mandatory parole, and fines ranging from $2,000 to $500,000.

The crash occurred around 1:21 p.m. on Sunday, April 27, 2025, as Dickinson and Arikita were traveling eastbound, climbing toward Horsetooth Mountain Park on the west side of the park. Conditions were clear and dry, and the posted speed limit in the area is 45 mph. The Colorado State Patrol has not issued a press release, but according to the initial crash report, Arikita, riding a 2023 Honda Rebel 1100, passed another motorcycle at nearly twice the posted speed limit, lost control, and ran onto the right shoulder, where the motorcycle struck Dickinson, who was riding his beloved Kestrel road bike. The bicycle came to rest in the grassy area on the right side of the road. The motorcycle continued eastbound, traveled off the left side of the road, and tumbled before coming to rest.

Dickinson was pronounced dead at the scene. Arikita, 61 at the time, was transported by ambulance to the Medical Center of the Rockies with serious injuries.

The District Attorney’s Office released the following statement:

“We are grateful that this investigation has been completed and the case has finally been filed with the District Attorney’s Office. We know this has been a long and frustrating process for Mr. Dickinson’s family and friends and we are eager to now begin working on the process of seeking justice in the criminal case. Our team stands ready to fight for vulnerable road users and knows our streets must be safe for motorists and cyclists alike. Our hearts go out to Mr. Dickinson’s family and the many community members we know have been impacted by his tragic death.

“The charges filed against Mr. Arikita are merely accusations and he remains presumed innocent unless and until he is found guilty in a court of law. Ethical obligations prevent us from commenting further until the case is resolved.”

Ian’s passing, and the lack of news regarding the investigation and the suspect, have had a profound and painful effect on his wife, two sons, and the entire Fort Collins cycling community, of which he was an active and beloved member.

Vivienne Dickinson, Ian’s wife, asked that I pass this message along to the community.

I would like you to pass on our thanks for all of the support and kindness that the cycling community in Fort Collins has shown to me and to our family, it really has meant a lot and I know Ian would be deeply grateful too.

I’d like to once again offer my condolences to Ian’s family, friends, and everyone affected by his passing. I also want to echo the family and community’s frustration with how long it has taken to get to this point. It reinforces our concern that the system will fail Ian, just like it failed Ollie and Magnus.

YGR has repeatedly reached out to the Colorado State Patrol for additional information and will update this story if and when that information is provided.
