MIAMI (WSVN) - Police said they have arrested a 14-year-old boy in connection with a crash on the Rickenbacker Causeway in Miami that killed a bicyclist last week.

Investigators said the crash happened when Vladyslav Kuchyn was riding an electric dirt bike eastbound in the designated bicycle lane, at around 8:30 p.m., Friday.

According to an arrest report, a witness told detectives that Kuchyn accelerated ahead of a group of juveniles on dirt bikes and rear-ended a man riding a bicycle alongside his wife.

The impact threw the cyclist into a concrete barrier and onto the ground.

Paramedics rushed the victim, 54-year-old Fabian Moses, to Jackson Memorial Hospital’s Ryder Trauma Center, where he was pronounced dead about an hour later.

Kuchyn also suffered a skull fracture and subdural hematoma in the crash.

Police said the dirt bike, a 2025 Surron Ultra Bee, was not registered in Florida and can reach speeds of nearly 60 mph. The bike, according to online records, can cost as much as $8,000.

Records show Kuchyn does not have a driver’s license and was ineligible to obtain one after failing to attend school.

Kuchyn was arrested on Thursday afternoon in Miami after voluntarily surrendering to authorities. He was charged with driving without a license causing death or serious injury.

Down south in Key Biscayne, commissioners voted to uphold a ban on motorized e-bikes and scooters on Tuesday. The decision came on the same week of a double tragedy on the Rickenbacker and Julia Tuttle Causeway.

Miami Police are still investigating a fatal crash on the Julia Tuttle, Tuesday, after a car crashed into an e-bike that had two people on it, sending both individuals to the hospital. One of the individuals succumbed to their injuries, and the other is said to be in critical condition.

Following the back-to-back incidents, Miami drivers are concerned over the safety of the roads.

About a half hour prior to the fatal Rickenbacker crash, said area resident Desmond Bounds was traveling west on the MacArthur Causeway when he recorded video of a pair of bicyclists performing dangerous stunts in the right lane with the camera on his Tesla.

“And there goes one of them popping a wheelie, swerving while he’s doing a wheelie,” said area resident Desmond Bounds as he described the video.

Authorities are not drawing any connections between the incident on the Rickenbacker and those bicyclists on the MacArthur Causeway.
