Name: Tern NBD P8i 2023 - Electric Folding Bike
Brand: Tern

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 favourite 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.

The NBD is our most accessible bike yet—you just hop on and go. Manoeuvring along streets and paths or through playgrounds and parks is child’s play thanks to a low centre 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.

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. 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.

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.

Tern Bikes Sizing Guide

Finding Your Perfect Fit

Most Tern bikes are designed in one size but are easily adjustable to fit riders of various heights. Whether you’re short, tall, or somewhere in between, Tern bikes are built to adapt and deliver a comfortable ride.

Adjustable Features

Tern bikes often come with the following adjustable components:

Telescopic Seatpost: Easily adjust the saddle height using quick-release levers.
Andros Stem: Modify handlebar height, angle, and orientation without tools.
Speedlifter Stem: Quickly adjust handlebar height for added comfort.

These adjustments make it simple to share your bike with others or customise your riding position.

How to Adjust Your Bike

Telescopic Seatpost

Adjusting Saddle Height:

Use the quick-release levers to extend or shorten the seatpost to your preferred height.
Ensure the seatpost stays within the minimum insertion range for safety (check the printed indicator on the post).

Finding the Right Height:

Sit on the bike and place your foot on the pedal in the 6 o’clock position.
Your leg should be slightly bent (80-90% of full extension).
Adjust until you find this position to ensure comfortable and efficient pedalling.

Tip: Remember the numbered height indicator on the seatpost for quick setup later.

Handlebar Adjustments

Andros Stem:

Use the quick-release levers to adjust handlebar height, angle, and orientation.
For road riding, position the handlebars forward; for comfort, angle them up toward you.

Speedlifter Stem:

Open the quick-release lever to adjust handlebar height.
Check that the quick release is firmly secured before riding to avoid risks.

Additional Adjustments

Saddle Position: Move the saddle forward/backward and adjust the tilt for improved comfort.
Handlebar Height Tips: Angling the handlebars slightly forward or back changes the feel of the steering, and swapping to a longer handlepost can provide more height if needed.
