Roadless wheel concept adjusts to all terrains

By - November 6, 2013 14 Pictures
Graduate student Ackeem Ngwenya has combined the 6000 year-old wheel with modern materials to develop a new type of all-terrain wheel assembly that switches from narrow to wide tread at the turn of a screw. His Roadless wheel system, while envisioned for rural applications in his native Malawi, has the potential to be as big a change to road (and off-road) transport as was the introduction of anti-lock braking.

Loopwheels put a spring in your cycling

When you have plenty of bicycle to work with, such as is the case with a mountain bike, it’s not such a big deal to design it with front and rear suspension. When the bicycle in question is a diminutive folding city bike, however, it gets a bit trickier. That’s why UK industrial designer Sam Pearce has created Loopwheels. Instead of relying on a suspension fork and rear shock, it lets the bike’s 20-inch wheels absorb the bumps. Read More

HubDock makes it easier to remove a bike's back wheel

By - February 21, 2013 5 Pictures
Probably just about all cyclists will agree – removing your bike’s rear wheel is a hassle. You have to open and loosen off the quick-release, pull the derailleur cage and chain back out of the way, smack the axle loose of the dropouts, and then guide the cassette cogs around the now-dangling chain. Your hands get dirty in the process, plus you get to look forward to repeating everything in reverse when putting the wheel back on. California-based inventor Leonard Ashman figured that the process ought to be easier, so he created the HubDock – it lets you remove your back wheel, without even touching the drivetrain. Read More

ARIS Sport throws a new curve at skateboard wheels

By - January 10, 2012 6 Pictures
The ability to carve into turns is something that is valued by surfers, snowboarders and skateboarders alike. While water and snow are relatively easy to carve into, however, concrete and asphalt are most definitely not, putting skateboards at a bit of a disadvantage. Attempts have been made at better-carving skateboards, including the pivoting-truck-equipped BMW StreetCarver, the many-wheeled Freebord, the caster-wheeled T-Board, and the twisting Ripstick and Skatecycle. Now, San Francisco-based ARIS Sport has addressed the issue with a novel solution – a line of skateboards with conical wheels. Read More

Puncture-proof Spring Tire picks up 2010 R&D 100 Award

By - November 14, 2010 1 Picture
Following a request from NASA, Goodyear last year developed an airless tire designed to transport large, long-range vehicles across the surface of celestial bodies such as the moon or Mars. The tire, constructed out of 800 load bearing springs, is designed to carry much heavier vehicles (up to 10 times) over much greater distances (up to 100 times) than the wire mesh tire that Goodyear helped develop for the Apollo Lunar Roving Vehicle (LRV). The Spring Tire has now been recognized with a so-called “Oscar of Innovation” at the 44th Annual R&D 100 Awards in Orlando, Florida. Read More
