Product Details
Turn your Greenspeed into an electric trike
Greenspeed was founded in Australia in 1990 and has been part of WizWheelz (TerraTrike's parent) since 2020. Greenspeed trikes stop with their front brakes and, in Greenspeed's words, there is "no rear brake on most" models, so the rear wheel converts cleanly. Greenspeed's 20 in wheels suit the Falco: the motor sits low and the trike stays planted. Owners ride Falco on the GT20, Magnum, Anura and the GTT5 tandem.
How to order: three choices above.
Your Greenspeed model. This sets your rear wheel size. Not listed? Pick "Other model / not sure" and we will confirm with you.
Controls. Wired plus/minus ($99), BLE wireless module to use the Falco Flash app ($149), wired console ($249), or the wireless module with plus/minus ($248) or console ($398).
Cassette. Move your own cassette across ($0), or we fit a new single-speed, 7, 8, 9, 10 or 11-speed cassette ($32 to $100).
The price shown is the full price for your choices: $2,295 for the system, plus controls and cassette. Speed limit: we ship set to 20 mph, the US road-legal limit. Need 15 mph (EU), 28 mph where legal, or an adjustable limit (+$99)? Add a note at checkout or call 877-278-6323. Shipping: $187 to the US, $212 to Canada, $420 to Europe, Australia, New Zealand and every other country. This includes the required hazmat fee for shipping the lithium battery.

Brant and Eileen have ridden their GTT5 on Falco for five years, including five Japanese islands.
GTO (older) (20 in rear) · Straight fit
20 in wheels all round.
GT3 (older) (16 in rear) · Call us first
16 in wheels and an offset rear end for a dishless wheel. We build 16 in f7.9 wheels; call us to match the offset.
What the conversion involves
Swap the rear wheel. The f7.9 arrives as a complete wheel, built in your size, with the motor, controller and sensors inside the hub. Move your cassette across, drop the wheel in and fit the torque arm.
Mount the battery. Most trike owners mount the 672 Wh battery behind the seat or on a rear rack, low and central.
Add the controls. Thumb throttle and a console or the Falco Flash app. Reverse and regenerative braking are set from the controls.
No cutting, drilling or welding. Most owners finish in an afternoon; any bike shop can do it.
Please read before you convert. Greenspeed's 10-year frame warranty is void for alterations such as cutting, drilling or welding, and for components not intended for or compatible with the trike. The f7.9 is a bolt-in wheel swap with no cutting or drilling. Some Greenspeed frames use an offset rear triangle; tell us the model and we build the wheel to suit.
Greenspeed’s own e-assist, and how the f7.9 differs
Greenspeed's own e+ Boost Kit is a Bosch Performance Line mid-drive (75 Nm, 400 Wh) on a replacement boom, for Magnum models only, $3,350. The f7.9 works on the whole range, with a 672 Wh battery, throttle, reverse and regenerative braking.

The Falco f7.9 is a 750 W, 48 V, 672 Wh electric drive that turns the bike, trike or tandem you already own into a smart eBike. The motor, controller, torque sensor and speed sensor are all inside the rear hub, so installation is a wheel swap plus a battery. It assists to 20 mph in the US (28 mph where legal), goes up to 120 miles on a charge at level 1, freewheels with zero resistance when the assist is off, and regenerates on descents. It is the same drive that powers the Three Wheels of Magic. Read what owners say in the customer stories.

Controls: pick what suits you
ANT+/BLE wireless module
Needed for wireless mode. It connects the motor to the Falco Flash app on your phone so you can set assist and regeneration levels, change modes, read the sensors and more.
Wired console
An eBike computer on a five-foot cable that plugs straight into the motor. No charging, no pairing: plug in, switch on, ride. It comes with a plus/minus controller for power levels, brake and wheel circumference.
Wired plus/minus
A simple controller for raising and lowering the power level, switching between pedal-assist and regeneration, applying the brake, and reverse on trikes.
Combinations. The wired plus/minus and the wireless module work together: set things up in the app, then ride without your phone. The wireless module and the wired console cannot be used at the same time; choose one.
Why it rides differently
Patented five-phase motor: zero freewheeling resistance, about 40% more power than a three-phase motor, high-efficiency assist and regeneration.
Torque and speed sensing: power arrives in proportion to how hard you pedal, so it feels like your own legs, only stronger. Adjust the level any time.
Clean installation: wireless console and plus/minus controller keep cables to a minimum.
Five-year motor warranty: a direct drive has no gears to wear, and we have built them since 2011.
