Is it for you?
Best suited to
Older riders, shorter riders and anyone returning to cycling who wants the easiest bike to get on and off.
Standout strength

The main compromise
The 140kg gross weight limit is lower than Tern's cargo bikes, so it is not a load hauler.

What is the range of the Tern NBD S5i?
The Tern NBD S5i has a claimed range of 51 to 118 km from its 500Wh battery. Real-world range is usually lower than the claim, since it depends on assist level, rider weight, terrain and wind.
What motor does the Tern NBD S5i have?
