Smiles for Miles

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.

EFBE Tested

EFBE Prüftechnik GmbH put the NBD through their rigorous Tri-Test to prove the frame and fork are safe for the rated 140 kg (308 lb) Maximum Gross Vehicle Weight.

UL Tested and Certified

The NBD’s Bosch motor system and battery are one of the few e-bike systems on the market that are UL tested and certified.

10-Year Warranty

We build our bikes to last, with a warranty to back them up. Register for Tern Care to get 10 years of warranty protection for the frame and fork.

Easy to Transport

The NBD’s FlatFold feature makes it easy to fit the bike into trains, buses, RVs, and even small-sized cars. Just lower the seatpost, fold down the Physis Handlepost, and the NBD transforms into a low and flat package. No bike racks necessary.

Easy to Store

The NBD parks and rolls vertically, so it’s easy to store safely indoors. Roll it vertically into elevators or conveniently park it just about anywhere in your home or office.

Share the Adventure

Have a kiddo? Take them along for the ride! The specially designed Gaia Rack is built strong and pairs well with many child seats. The NBD’s ultra-low center of gravity makes it much easier to stay in control.

Best of all is getting on the bike. Low, gentle steps are all that’s required to get on or off the NBD, so there’s never any hassle.

Why the NBD?


SimpleStep Frame Design

The NBD's frame design makes it super easy to get on and off the bike, ride in comfort, and put your feet down when at a red light—even when you’re fully loaded with groceries or carrying your little one.

Low, Low, Low Step

A step-through frame that's both ultra-low (39 cm/15.4") and ultra-long means it takes only one step to get on and go.

Fits Most Sizes and Shapes

The adjustable Andros Stem makes the NBD feel like it was tailor-made. Riders of different sizes can all find their most comfortable position. And when it’s time to share with grandpa, he can re-adjust the fit in seconds.


Ergonomic Cockpit

Swept handlebars and Ergon grips make the NBD just about the most comfortable cockpit you'll find on a bike. The slack seat tube enables all riders—even the smaller in stature—to place their feet on the ground at stops.

RideEasy Suspension Seatpost

The custom short-stack suspension seatpost adjusts to fit riders of different heights, and allows even smaller sized riders to travel without feeling road vibrations.

Air-Cushion Balloon Tires

No special technology needed—air suspension is already built in. The air cushion from Schwalbe’s wide balloon tires give a smooth ride, helping to reduce bumps and other road vibrations when riding.

Feet-Friendly Pedals

The platform of the pedal is extra-large for boosted foot stability. Feet naturally and securely snug into its gentle concave shape. And the pedal has an improved grip for all types of shoes.


Smooth, Powerful Motor

The Bosch e-assist motor system is powerful, efficient, smooth, and supremely quiet. It’s also backed with best-in-class service and support, and a network of thousands of trained dealers in cities around the world. 

Bold, Bright, and Easy to Read

The Bosch Intuvia display has all the information you need. It's easy to read on your daytime rides, and it’s brightly lit for when you ride at night. Plus, the entire display is removable and perfectly sized for pockets, so you can carry it with you after you park.

Hassle-Free Belt Drive

Bike chains are great, but often need cleaning and lubing. The NBD S5i comes equipped with a Gates belt drive for durability, low maintenance and a smoother and quieter ride, so you can spend less time cleaning, and more time riding.

Easy-Access Frame Lock

With an Abus frame lock at the top of the rear wheel, most riders can lock up without having to bend down low. And for added simplicity, you’ll need only one key, as the frame lock and battery lock are keyed alike.
