“When it first came out, I just had to have it,” said avid e-bike rider Helen Kahawai Clark. “I just love it!”

Kahawai Clark bought her e-bike years ago and can’t get enough of it.

She’s not alone.

E-bikes are booming. In fact, according to the city, in the past two years the number of e-bikes registered in Honolulu more than quadrupled. 

This year e-bike registrations could even surpass regular bikes.

                               Bike       e-bike

FY2021                  25,344   1,424

FY2022                  16,417   4,943

FYTD 2023              9,864     7,811    

Justin Vinoya, The Bike Factory supervisor, said they usually sell at least one e-bike a day.

And for all their convenience, Vinoya admitted riding a motorized bike traveling between 15 to 28 mph, can be daunting.

“Even though it doesn’t feel like it’s fast, it is fast in a way like especially if you’re keeping up with traffic.”

Kahawai Clark said it makes her uncomfortable when she sees e-bikes speeding down the road keeping up with traffic.

“I cringe when I see them,” she said. “To me, it’s dangerous because a lot of times they don’t have a helmet; and a lot of times they’re doing pop a wheelies. And it just doesn’t look safe.”

Hawaii Bicycling League Executive Director Travis Counsell said if people don’t follow the rules and don’t know how to ride properly it is dangerous.

“When people might not know how to control [e-bikes] or understand how much power they have, could really find themselves in situations where it would be unsafe,” Counsell explained.

Rick Bruno, president of Queens Medical Center said they are seeing an uptick in e-bike related injuries.

“We see an e-bike injuries a couple of times a month,” Bruno added, “and we expect to continue to see more.”

The injuries are similar to other bicycle injuries

“Mostly orthopedic injuries,” he said. “But we can see serious injuries related to head injuries when people fall.”

According to Bruno, they just started tracking e-bike and motorized bicycle injuries last year.

Safety is key when riding an e-bike, and wearing a helmet is one of the easiest ways to prevent a serious head injury.

Experts said e-bike riders need to take reaction time into consideration in case they have to make a sudden stop.

Counsell said paying attention to their surroundings and being familiar with the bike are also important.

Hawaii law prohibits anyone under the age of 15 from riding an e-bike. Counsell said the Hawaii Bicycling League is working with law makers to better regulate e-bikes.

HBL offers free workshops for e-bikes.

“Ride responsibly, you know, share the road with aloha,” concluded Counsell.
