A Hubless Harley-Davidson Chopper Is One Sure Way to Get Attention

For most riders, a Harley-Davidson is beautiful on its own and, if you add the growl of the engine, there’s enough happening to get attention. But there are other ways you can stand out even more, should you be interested. Hubless choppers are one such option. They are futuristic, almost alien-looking custom bikes built by hand around a Harley-Davidson frame, with wild-looking paintwork and at least one spoke-less wheel. Invented by Franco Sbarro and most famously used on the 1989 Sbarro Osmos, the center-less wheel is difficult to make, difficult to maintain and has many practical disadvantages. But it’s bound to get you noticed. Perhaps the first, most famous chopper to get international media attention is the Hubless Custom by New Jersey-based Howard’s Killer Custom, which was unveiled in late 2007 and is believed to have cost no less than $155,000. It is usually included on lists of most expensive motorcycles in the world. It partially started out as a classic 1969 FL Harley-Davidson, which, in the hands of Howard Sofield, became the most famous hubless chopper in the world. Weighing about 700 pounds and able to reach speeds of 100 mph, the Hubless Custom took 4,000 hours to make and two full years of research and design. According to Sofield, the Hubless Custom started out with a 1974 swing arm frame and a 21-inch front wheel, the 1969 Harley-Davidson Pan Shovel 80ci engine, 1969 & 1974 Harley-Davidson engine cases, and 1982 Harley-Davidson cylinders. The goal was to make the hubless wheel more practical and to create a fully functional bike in-house. “Using my experience in drafting and automotive industries I was able to come up with a different way to make the hubless wheel work in a more practical way,” Sofield said upon the bike’s introduction. “Combining that with […]

NAWA’s Radical Electric Motorcycle Highlights The Potential Of Supercapacitors In EVs

by Bill Roberson from https://www.forbes.com/ Despite the fact that they have built an electric motorcycle, French tech company NAWA Technologies, or just NAWA for short, isn’t in the business of building electric motorcycles – they build batteries. But maybe they should reconsider the motorcycle market option, especially in light of the one-off bike they did just indeed build, because it’s a serious looker packed with possibly industry-changing technologies. The NAWA Racer’s sleek, minimalist styling comes courtesy of a collaboration with Envisage Group, who have been involved with Jaguar and other brands that want some cool lines with their new tech. One highlight is a hubless rear wheel, although the bike is covered in cool touches including the wrap-around LED taillight and duck-tailed seat. But beyond the slick lines and hubless rear hoop of the NAWA Racer, the cafe-racer inspired from-the-future motorbike carries an underlying technology that significantly boosts performance and could signal a significant step forward for electric motorcycle performance – or the performance potential of anything that needs batteries for motive power, including electric cars. NAWA has added a supercapacitor to the Racer (NAWA calls it an ultracapacitor, and have branded it as NAWACap), and the short version of the technese is this: A supercapacitor is similar to a battery, except it can be charged in seconds, and can then dump that charge at an extremely high rate – far beyond what a battery can provide – for an instant boost in power. It can also repeat that feat millions of times without any substantial performance losses. NAWA isn’t the first company to put a supercapacitor into service; supercar maker Lamborghini is integrating a supercapacitor system into their new Sián hypercar (sorry, but all 63 are sold out at $3.6 million per copy). According to information provided by NAWA,
