The Falco f7.9 is a rear-hub electric drive kit that converts a bike, trike or tandem you already own into an eBike. The 750 W motor, controller, torque sensor and speed sensor all sit inside the hub, so installation is a wheel swap plus a battery. It assists to 20 mph in the US (28 mph where legal), freewheels with no drag when off, and regenerates on descents. It suits riders who want to electrify a specific frame rather than buy a new eBike, and it asks you to confirm frame, wheel size and dropouts first.

Rated 5 out of 5 from 47 ratings. Owners praise the integrated hub design and the freewheeling feel with assist off.
The Falco f7.9 is a 750 W, 48 V, 672 Wh electric drive that converts a bike, trike or tandem into an eBike. The motor, controller, torque sensor and speed sensor are all built into the rear hub. Installation is a wheel swap plus a battery.
Assist is limited to 20 mph in the US, or 28 mph where legal. Range is up to 120 miles on a charge at assist level 1. The motor freewheels with zero resistance when assist is off and regenerates on descents. The patented five-phase motor gives about 40% more power than a three-phase motor. Torque and speed sensing deliver power in proportion to how hard you pedal.
The ANT+/BLE wireless module connects the motor to the Falco Flash app, where you set assist and regeneration levels, change modes and read sensors. The wired console is an eBike computer on a five-foot cable that plugs into the motor, with no charging or pairing. The wired plus/minus controller raises and lowers power, switches between pedal-assist and regeneration, applies the brake, and provides reverse on trikes. The plus/minus controller and wireless module can be used together. The wireless module and wired console cannot be used at the same time.
