2-wheeled Tern NBD model in Silver Blue


Small in size but big on smiles, the NBD is an easy-to-ride, ultra-low step e-bike that’s comfy and welcoming—just like your favorite bike should be. Whether you’re a seasoned rider or just thinking about your first e-bike, or whether you’re doing a quick grocery run or setting off on a new adventure with your kid, the NBD will bring a smile to your face.

Easy to Ride

The NBD is our most accessible bike yet—you just hop on and go. Maneuvering along streets and paths or through playgrounds and parks is child’s play thanks to a low center of gravity. Riders have maximum control, and the ultra-low stepover height makes getting off and then back on again a breeze—even when taking a kiddo.

Easy to Share

The NBD has an adjustable cockpit that only takes seconds to resize, all without tools. Riders 147 – 190 cm tall (4’10” – 6’3”) comfortably fit the NBD, so it comes ready for the whole family to share.

Easy for Everyone

The NBD puts inclusive design at the forefront. Average-sized, able-bodied folks along with people of many different sizes and abilities can share the fun of riding thanks to the NBD’s accommodating geometry and unique frame design.

As Comfortable as Can Be

With wide, ergonomic grips on swept handlebars, an upright riding position, and a multi-adjustable stem, the NBD is our most comfortable bike. Add wide balloon tires and a suspension seatpost to the mix, and most road vibration becomes a thing of the past.

Tested for Safety

Peace of mind is knowing that the NBD’s frame, fork, motor, and battery have been laboratory tested to the industry’s highest safety standards.
