Hiboy EX9
The city bike that reads your legs.
A dual-sided torque sensor meters assist from both pedals, a 1000W peak motor handles the bridge, and a 59.5 lb frame carries up the stairs. The EX9 is Hiboy’s most refined commuter.
Battery capacity, UL2272 certified.
Tires sized for stability at speed.
Maximum rider load on the frame.
