Seeing the Florida Keys on an e-bike is VIP style type of experience.
We recommend the paved trail on the side of US-1 spanning from MM110 to MM94 for Key Largo, ocean side. It's safe and you will share with walkers/runners. You can also ride on a few sections of paved trail on the bay side, but it's not available everywhere in Key Largo.

Getting into Tavernier: Just like in Key Largo, continue riding the paved trail on the side of US-1 spanning from MM94 to MM89, ocean side. It's safe and you will share with walker/runners. Feel free to take a left turn on Burton Dr and explore Harry Harris Park.

Islamorada: Take the Old Hwy (Old US-1). Make a full stop at each STOP sign: it's the law !
