The wonderfully named Black Sparrow Industries has cooked up an electric vehicle with a difference: a tricycle that's ridden standing up. Robert Worobey designed the Tribey to appeal to surfers and snowboarders among others, and the designer claims that the vehicle is built to withstand serious abuse, including traversing 3-inch deep potholes. With the addition of a bolt-on kit, The Tribey can also be ridden from a recumbent position, making the Tribey a curious hybrid of recumbent trike and a motorized skateboard.

The Tribey measures 78 inches (198 cm) long, 30 inches (76.2 cm) wide and weighs 90 pounds (40.8 kg). The trike is fitted with a 48-V 10-Ah battery pack and MagicPie 3 wheel hub motor (rated at 1 kW) from Golden Motor, a supplier of equipment to convert ordinary pushbikes into fully-fledged EVs.

The spec allows a 195-pound (88.5-kg) rider to reach a claimed top speed of 25 mph (40.2 km/h), though top speed can be tuned down via a computer. Black Sparrow Industries says the Tribey has a range of about 18 miles on a single charge, though points out that this will depend on terrain, weather, and how you treat the thumb-controlled throttle.

The Tribey is designed to be both repairable and upgradable. The rear assembly can be upgraded to anything with a 1.25-inch tube diameter, and Black Sparrow Industries even suggests that bicycle trailers and surf board rack can be fitted (though you'd better live pretty close to the beach to make use of the latter item).

The mark 7 Tribey will shortly go on sale. Built to order, Tribeys are available only to customers over 16 years of age, and will be required to sign a liability waiver (so, use at your own risk, basically). The price of the mark 7 is currently listed at US$2499.

Twenty-four images but not a single on showing the thing being ridden as a recumbent. Growl!


As soon as I find my gopro I'll post a video with me riding it with the seat :)

Interesting "concept" however that square ?? seat mount?? near the rear leg needs to be able to be relocated when used for standing....

Also the power module could be mounted flat to avoid damage when this contraption flips....

If it isn't powerful enough or fast enough to have an accident no-one will use it for the intended purpose of riding skate style....

Something like this needs to give the rider a bit of a rush to be worth the effort.. while as a recumbent electrocycle it is merely a mode of transport....

(The 1kw electric motor will be too powerful for it to be regarded as an electrified bicycle meaning that it must be registered as a moped in many jurisdictions....

if it isn't going to be street legal then use a 2-3 kw motor for the Adrenaline junkies.


The rear square is clear of your legs when not in use. It has plenty of power to reach 25 mph. I've gone 32 mph on another design and that was just dangerous, and scary. The practical application of the Tribey is to be able to mount and pull luggage, cargo, and groceries. As for the laws of registration, all states are different. MA requires it to be registered if it exceeds 3.7 kw or has a speed exceeding 30 mph.

Looks like fun but for something that you stand on at 30km/h there's WAY too many sharp edges and protrusions on that thing.

Stand? Sit? I can't say. Is this the most indecisive design I've seen? Maybe. Maybe not.
