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 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.
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.
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.
Built to Last
Our philosophy is to keep our bikes on the road for as long as possible, not to create disposable products that are built to fail. We start with intentional design choices that make the bike serviceable and safe—and end up with a reliable vehicle you can use day in, day out. Then, we back it up with great local service and a 10-year warranty for peace of mind.
Why the NBD
Tough and Tested
EFBE Prüftechnik GmbH, one of Europe’s leading bicycle testing labs, put the NBD through its paces to prove the frame and fork can handle the 140 kg (309 lb) mass gross vehicle weight ride after ride.
UL Tested and Certified
The NBD’s Bosch motor system and battery are UL-2849 certified. They’ve been carefully tested for safety against potential hazards.
Built and Assembled by Experts
Your NBD is carefully built by certified Tern Dealers who will run through a thorough pre-delivery safety checklist before handing over your new bike.
IT’S REALLY FOR EVERYONE
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.
IT’S REALLY THAT COMFY
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.
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.
IT’S REALLY THAT GREAT
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.
