Trike

B'kid is designed in such a way that it is adaptable to the needs of a growing child, with...

The rate at which children grow, especially from being new-born to the age of around six-years-old, is scary. One day they're a helpless ball of flesh and bones, the next they're walking, talking, and starting school. This means that new parents have to continually buy new things for their child that may only last them a matter of months. While a bicycle may not be top of the agenda at such a young age, for a child to learn to ride one means buying several different models over the course of just a few years as they first learn, and then master, the art. Which is what led Noelia Vallano Alvaro to design B'kid: one bike designed to last a child from the age of two right through to the age of six.  Read More

Rennholz features custom 16-inch rims at the front and a 20-inch rear wheel, all using Sch...

The term "run" in the heading is perhaps a little generous, as the Rennholz trike can only actually go up to a top speed of 15 mph (24 km/h) for about ten minutes before needing a battery swap. Literally translated as Race Wood, it's by no means the only example of a drill-powered vehicle but the gorgeous curves of its shaped wood frame and familiar trike form factor make it much more of an eye-pleaser than, say, the University of Louisiana's Cajun Crawler. It was planned, designed and built by a team of product design students from HAWK University of Applied Sciences and Arts at Hildesheim in Germany for last year's Cordless Screwdriver Race and although it didn't actually win, the design did take both the Jury and Public awards at the race.  Read More

The paragliding motor trike concept by Zvezdan Nedeljkovic

It seems like such a simple concept, something Q might whip up for 007 in the next Bond flick: hook a recumbent electric motorcycle up to a paraglider, drive it off a cliff and see what happens. That's the thinking behind this offering from Serbian designer Zvezdan Nedeljkovic, and while the idea of attaching vehicles to parasails is far from new, there's something about Nedeljkovic's concept design that captures the imagination.  Read More

If the US$6,000 price tag of the BugE trike is still beyond your price range, then you may be interested in the sub-US$600 Solaron three-wheeler designed by Pakistan's Farrukh Khan. The DIY project is not (yet) available commercially, but the young inventor has posted detailed build instructions online for those who want to knock up their own variants.  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

On December 7, renewable energy advocate Tom Weis concluded a 10-week ride across America in his pedal-powered hybrid electric-assist “Rocket Trike." He collected opinions and signatures from people on “Main Street, USA” in support of a 100 percent green electricity grid by 2020 to present to key members of congress, the President and First Lady.  Read More

The BugE is a faired electric three-wheeler that buyers purchase as a kit, then put togeth...

Electric vehicles are beginning to spread onto the mass market, but one of the limiting factors in these early days is a high-cost compared to their gas-burning equivalents. Electric scooters and motorcycles are considerably cheaper, but not everyone is comfortable on two wheels, or likes being exposed to the elements. Here's an alternative type of EV that costs less than six thousand dollars, is stable on the road and will protect you from wind and rain. It’s called the BugE, and there’s just one catch to it – you have to put the thing together yourself.  Read More

My first attempt at rowing a boat on a park pond was the source of some considerable embarrassment. As I went round and round in ever decreasing circles, I remember thinking that there must have been something wrong with the steering. Troels Øhman's RowRay though may just tempt me back to the oars. Designed to bring a fun element to family exercise, the three-wheeled landcart concept is driven by grabbing hold of the two handles and pulling back for dear life. Turning the cart is a matter of pulling on the left or right "oar" and the designer sees users being able to take one for a spin by using a smartphone to unlock it from a base station at the beach or in the park.  Read More

The TW4XP three-wheeler, representing the production human/electric hybrid Twike

It would be a huge understatement to say that the 12 vehicles remaining in the Automotive X PRIZE are pretty unusual. One of the things that was particularly fun for those of us recently attending the Finals Stage in Michigan, in fact, was observing all the different forms and configurations that the different teams’ automobiles have taken. One standout (and they’re all standouts really) has been the TW4XP, representing the team of the same name. The vehicle is a sneak-peek of the next generation of Twike, a production electric three-wheeler built and sold by some of the team members back home in Germany. One of the things that makes regular Twikes special is the fact that they have pedals, so you can extend their range by giving the battery a break and pedaling on the easy stuff. While other X PRIZE contenders such as the Aptera may be sexier than the TW4XP, it represents an already-available vehicle that could help you work off those unwanted extra pounds.  Read More

The Italtrike oko and oko Plus

If you’re excited by the new Ducati 1198, but are perhaps a little too poor or timid to buy one, here’s the next-best thing – a top-of-the-line Italian tricycle for your kid. Not only is Italtrike's oko, well, you know... Italian, but it also sports some rather clever features that make it safer and more practical than your average Lilliputian three-wheeler.  Read More
