Three Wheel

The toilet trike will hit the Japanese roads in the coming days, making its way from Kyush...

If you think this smells like a PR stunt, you're right. In an effort to raise awareness about bathroom emissions and water savings, Japanese toilet manufacturer TOTO has created the Toilet Bike Neo Project ... yep, it's a road-going, three-wheeled toilet fueled by "biogas" generated from the toilet waste.  Read More

The Lithium Hawk three-wheeled homebuilt electric vehicle (Photo: Nap Pepin)

Four years ago, Canadian electronics engineering technologist Nap Pepin decided to buy a kit for a BugE electric vehicle. Not content with its out-of-the-box performance, he swapped in a lithium battery pack, and his own custom battery management system. This boosted its top speed from 80 km/h (50 mph) to 130 km/h (80 mph), and its range from around 48 km (30 miles) to 200 km (125 miles). For his next project, however, he wanted to build an EV from scratch. The result is his 197 km/h (122 mph) three-wheeled Lithium Hawk, which has just taken to the roads. We paid a visit to Nap for a closer look at his impressive machine.  Read More

The Thrustcycle SRT is a three-wheeled vehicle that incorporates a gyro/flywheel system to...

Fans of three-wheeled cars will tell you that the vehicles come in two configurations: delta, with the single wheel in the front, and tadpole, with the single wheel in the back. Well, now there's another type. The prototype Thrustcycle SRT has all three of its wheels in a straight lateral line, and utilizes a mechanical gyroscopic stabilizing system to keep it firmly upright even when standing still. That same system also stores kinetic energy generated by braking, extending the vehicle's range.  Read More

The tilting Swingtrike

Getting about on a bicycle is environmentally friendly, great for your health and cost effective. One drawback – particularly for those learning to ride or for whom balance is an issue – is the instability that comes with being on two wheels at low speeds. Tricycles offer a way to overcome this problem, but three-wheelers have their own set of stability issues when it comes to cornering at higher speeds. Like the Deliver-E Trike we looked at earlier this year, the Swingtrike aims to provide a best of both world solution by employing a tilting design that keeps all wheels on the ground across bumpy terrain and through corners, making it safer – and more fun – than traditional fixed frame trikes.  Read More

Geely McCar is a combined car and motorcycle

One of the most imaginative concept cars we’ve ever seen turned up at Auto Shanghai this week and it didn’t come from Japan, Germany, France or America – it was the result of two years work in China by Geely engineers and is the synthesis of over 60 IP-protected ideas. In essence, it’s an ultra compact, two-door, four-seater with a built-in, folding three wheeled electric scooter in the rear. When the scooter is docked, the car shares both its battery and electric motor to extend the all-electric range or ensure the scooter is fully charged. The vehicle is proposed as having choice of gas-electric hybrid or fully electric powerplants. Sheer genius … and a catchy name which must surely attract a legal challenge.  Read More

Inventor Simon Williams and his Deliver-E Trike

When those of us who live in urban areas picture letter carriers – or posties, or mailmen/women – we usually think of them as people who deliver the mail by foot. The fact is, however, letter carriers in much of the world use small motorcycles to make their deliveries. If Australian inventor Simon Williams has his way, many of those motorcycles may soon be replaced by his electric three-wheeler. Not only is the Williams Deliver-E Trike quieter and cleaner than gas-powered bikes, but its two rear swing arms pivot independently, allowing the vehicle to lean into turns and stand upright when parked at the side of a sloping road.  Read More

The new Morgan three-wheel cyclecar

The cyclecar was a cross between a motorcycle and a car that popular a 100 years ago, mainly because the extremely light weight and powerful big V-twin motorcycle engine gave it sporting performance. Only one of the original cyclecar manufacturers still exists today – Morgan – and in a remarkable announcement, the entire concept has been updated and will sell for GBP25,000 powered by a big 115 bhp S&S V-twin, a five-speed Mazda gearbox and a cockpit modeled on a WW1 fighter plane.  Read More

The Manta three-wheeler amphibious concept vehicle has an electric motor on each of the re...

Although I live by a river, I don't own a boat so am not faced with having to drag a trailer down to the water's edge and unload my dinghy every time I want to cross the great expanse. I might just be persuaded to spend more time on the water, though, if there was something like the Manta waiting outside my front door. The sporty-looking three-wheeler concept is designed to be run on twin electric motors, with the rear wheels taking care of propulsion on water as well as on the road. The design is amongst the entries chosen by this year's Michelin Challenge Design judges for display at the recent North American International Auto Show.  Read More

If the notion of flying through the air appeals then hang-gliding might be your first thought. But if your fear of heights keeps you closer to the ground then perhaps Dr Carsten Mehring's StreetFlyer may be of interest. The human-powered three-wheeler suspends its user from an arched frame so that when enough momentum is generated, the legs can be lifted off the ground and you're away – at a cruising altitude of just a few feet.  Read More

Citroen E-3POD Antistatic Concept: ultralight, micro segment electric three-wheeler

The recently finalized Double Challenge project required MA students at London’s Royal College of Art to design an ultra-compact electric vehicle for event sponsor Citroën. Not surprisingly from such distilled intelligence, the winning entry is a new type of personal urban commuter positioned between bicycles and cars – light, aerodynamically efficient, cheap to build and economical in its use of energy and hence run. Heikki Juvonen’s “E-3POD Antistatic” is an ultralight, micro segment electric three-wheeler with the driver sitting inside a large hub-less third wheel.  Read More
