Suspension has long been a dirty word among road-racing cyclists, but if carbon fiber wizard and cycling visionary Craig Calfee nails his latest prediction as cleanly as his previous ones, it won't be long before every rider in the Tour de France is enjoying the comfort, performance and traction benefits of a suspended rear end. Calfee's top-of-the-line Manta bikes now feature an incredibly simple, lightweight rear suspension spring with a tiny 12 mm of travel that he believes will revolutionize the sport. Gizmag visited the Calfee workshop in Santa Cruz to find out more.Read More
While there are various ways of stowing a compact tire pump within a bicycle, a full-size model is almost always going to make the pumping easier. Frame-fit hand pumps are certainly one way to go, but inventor Alexander Haager has created something stealthier – his AirSupply pump doubles as a seatpost.Read More
As we see each year at events like the North American Handmade Bicycle Show and Eurobike, bicycle designers will experiment with just about any style of frame. But they always seems to come back to the tried-and-true classic – the diamond frame. Perhaps, it's no wonder, then, that the e-bike industry is following suit. Propella is the latest startup to disguise its e-bike as a simple diamond-frame bicycle. Unlike a regular diamond-frame bicycle, this one has a versatile electric drive with both a throttle and a pedal assist system.
Although they're still far from being common, 3D-printed metal bicycle frames do now exist. Usually they're made using a sintering process, in which a laser is utilized to selectively melt steel powder, building it up in successive layers. Now, however, a team of students at the Delft University of Technology (TU Delft) in the Netherlands has taken another approach – they've created the world's first stainless steel bike made via a welding-based 3D-printing technique.Read More
Many mountain bikers swear by the pedalling efficiency of so-called clipless pedals, in which a steel cleat on the bottom of each shoe engages a spring-loaded mechanism in the pedal. Some other riders, however, just don't like the idea of being "snapped in" like that. It was with this in mind that cyclist Dave Williams created MagLOCK pedals. They're non-threatening platform pedals, that keep the user's feet in place using magnets instead of mechanisms. We recently had a chance to try them out, and generally liked what they had to offer.Read More
Stealth makes some of the baddest electric-powered two-wheeled transport around. We can attest to this after having an absolute blast on the Australian company's high-powered flagship, the B-52, but what happens when you take an extreme e-bike and replace the pedals with dirtbike-style pegs? We climbed aboard Stealth's H-52 model to find out.Read More
Some are louder than others, but e-bikes are usually easy to spot. Evidence like a battery pack sticking up off the down tube, a thick, rectangular top tube or a large motor on the wheel is hard to miss. German startup Freygeist believes that the electric bike should look and feel more like the classic pedal bike. Its new Classic pedelec is virtually indistinguishable as an electric thanks to cleanly integrated hardware and a 26.5-lb curb weight. You won't notice the electric drive until it kicks in.
Recumbent bicycles may offer a more comfortable riding position, but they typically also have pretty long chains. After all, power has to be transmitted from the pedals at the front to the drive wheel at the back. Norway-based inventor Marc Le Borgne, however, has created an alternative. His KerVelo recumbent has an 18-speed gearhub transmission built into the front wheel.Read More
There's no denying that good-quality bike locks tend to be heavy, plus they're often awkward to carry. While we have seen efforts to make them lighter and less obtrusive, Latvian startup GreyNut has gone a step farther – its Bindio system simply places the lock at a parking spot at the cyclist's destination, so it's already there waiting for them.Read More
