Component Specifications
Sourced from Tern's published specifications for the BYB P8. Data note: Tern's published spec sheet for the BYB P8 lists no motor, battery, or display component — this is a manual (non-electric) folding bike, despite being grouped with Vektron e-bikes in this batch. Built in one universal frame size.
