Details That Matter

  • Step-on friendly: ultra-low standover frame means easier mounting even in skirts or for shorter riders.
  • Durability built in: belt drive + internal hub = fewer parts to worry about.
  • Power when you need it: Bosch Performance motor gives confident assist; quiet under load.
  • Brakes & control: hydraulic disc brakes deliver consistent stopping—even under load.
    Compact fold: folds down tight without sacrificing ride performance or strength.

Is This Your Bike? Read On.

Go with the NBD S5i if you want an ebike that’s friendly, tough, and confident without being oversized. It’s ideal for urban commutes, errands, or anything you can throw between home and transit. The low-step through frame is easy to get on and off.

Skip it if you need to haul more than one child, or you need heavy cargo capacity beyond what the frame supports.

Pure Tern

Tern designs bikes for how people live, not how they “should.” The NBD S5i fits that mission: thoughtful, usable, durable. It doesn’t ask for compromises; it builds on logic for life on two wheels.
