All parts drawings illustrate only one application of each fitting. In most cases many other applications are possible. The channels shown in the illustrations are P1000, 15⁄8" square, except where noted otherwise. All 9⁄16" diameter holes use 1⁄2" x 15⁄16" hex head cap screws and 1⁄2" nuts – P1010, P3010, P4010 or P5510 – depending on the channel used. Nuts and bolts are not included with the fitting and must be ordered separately.

The way the loop-ends overlap each other, it looks like that would give some lateral stability.

The design most likely requires a drum or disc brake since the rim’s position would likely change too much for rim brakes. We’re thinking this could be a fun design for commuter and city bikes where aerodynamics and weight are slightly trumped by comfort, particularly where the streets are a bit rough.

When I refer to this trike as such, the word “ultimate” seems to annoy some people. They ask questions, such as “Where do you get off, calling this the ‘Ultimate Sprint’?” They ask upon what do I base that description, isn’t it just a matter of opinion, and so on. When I finally get the chance to just say: this is the trike that ICE put in its “Ultimate Collection”, they just look momentarily lost for a comment, then eventually just nod. And now that we’ve got that out of the way, let’s look at this trike, OK? Vinyl Graphics from the Flaming Eyeball Posted on July 17, 2020 by Larry Varney

Thank you for your interest in contacting Future Engineers. We look forward to connecting with you!
The new company has financial backing from the RAD BioMed Accelerator group and is in collaboration with the Ziv-Av Engineering group. They are initially designing these wheels for wheelchairs, city bicycles and aircraft landing gear but the company says the technology would be used for other wheeled vehicles.
Loopwheels reduce the level of vibration—“road noise”—through the chair frame and up into the arms, wrists and shoulders.
Usually the half-axle is broadened into a V with front and rear pivots to keep it from twisting. Pivots allow the bar to twist, but to a limited degree so that rolling is controlled.
