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.
Tap a feature. See what it does.

Dual-Sided Torque Sensor —
A bottom-bracket sensor reads force from both pedals rather than one, so assist responds instantly and evenly. The bike feels like your own legs, only stronger.

1000W Peak Power —
A 750W motor with 1000W peak. Fast starts from lights and a 20% hill rating that takes the sweat out of uphill commutes.

62 Miles Range —
The removable 48V 11.6Ah battery is rated for 62 miles with assist and 31 miles on throttle, which covers a full week of typical commuting.

Hydraulic Disc Brakes —
Hydraulic discs at both wheels with motor cutoff. Strong, consistent stops in city rain.

Comfort That Adapts
An 80mm suspension fork and 2.5-inch-wide tires soak up the seams and patches of urban streets.

The EX9, in detail.



For the rider who wants a bike, not a moped.
The EX9’s torque sensor is the feature that separates a pleasant e-bike from a clumsy one. Add hydraulic brakes, an adjustable stem, and a frame you can carry, and it is the Hiboy for people who commute by bike because they like riding.
Ships from our US warehouse with Hiboy’s 1-year warranty on the frame, motor, battery, and controller. Financing is available at checkout through Affirm, Klarna, Afterpay, and PayPal, and shipping is free to the lower 48 states.
