Horseback riders and horse-drawn carriages have long experienced problems with speeding bicyclists on the carriage roads of Acadia National Park, but with the recent introduction of electronic bikes, or e-bikes, the issue has only gotten worse.

Equestrians have reported e-bikes approaching horses from behind and speeding past, closely, with no warning, said Christie Anastasia, public affairs specialist for Acadia National Park. While people with disabilities have always been allowed to ride e-bikes on the park’s carriage roads, it wasn’t until fall 2019 that e-bikes became an option for all park visitors.
