We haven't been paying much attention to the custom motorcycle world lately, but this jaw-dropping project demanded our attention. It's a Hayabusa engine wrapped in a spectacular titanium frame, swingarm, exhaust, subframe and bodywork.
Titanium is 45% lighter than steel, with the same strength. Compared to aluminum, it's twice as strong, but only weighs 60% more. That's why it's often used in aerospace, where high strength and light weight are critical factors. It also oxidizes into brilliant, permanent colors when you point a blowtorch at it, which can make it a damn near pornographic material for motorcycle exhausts and the like.
So why haven't we seen a full titanium motorcycle before? Well, for starters, it costs a lot more than something like aluminum. It's also a pain in the butt to work with. It's highly reactive at high temperatures, for example, so if you weld it in ambient air, it reacts with oxygen, nitrogen, or even the carbon in steel tools, creating brittle compounds and often wrecking the tools. It tends to stick to cutting tools and ruin those, too.
In sheet form, it's extremely springy, wanting to return to its original shape, so it takes a lot of extra effort to work into the kinds of complex shapes needed for motorcycle bodywork. But, as briefly outlined in the video below, that's part of the attraction for New Jersey custom builder W. Robert Ransom.
Ransom took on this all-titanium motorcycle project on behalf of a customer called Mohammed, hoping it would become "a display of artistry and craftsmanship previously not seen in the motorcycle industry."

Addmotor lansează tricicletă pliabilă de 90 de mile cu asistare la pedală pentru mai puțin de 2.000 USD
Though cargo ebikes are shaping up as an eco-friendly alternative to the family car for short shopping trips, riders looking for more stability will doubtless appreciate a third wheel. California's Addmotor has just launched a 90-mile e-trike for under $2,000.
Where the 2023 M-340 e-trike employed a front hub motor, the CityTri E-310 rocs a proprietary 750-W motor mounted between the rear wheels that peaks at 1,400 watts, produces 90 Nm (66 lb.ft) of torque, and includes a differential for cornering stability.

It never fails … you go to use a device that should be fully charged, but its battery has gone flat over time. Such may soon no longer be the case, however, if battery manufacturers simply start using a different type of adhesive tape.
When commercial lithium-ion batteries are being assembled, polyethylene terephthalate (PET) tape is utilized to keep their electrode stacks from unwinding. And while the mechanical and electrical properties of the polymer are good for the job, scientists at Canada's Dalhousie University state that its chemical stability has been largely overlooked.
