A bicycle made entirely out if glass; blown, cast, ground - as appropriate.
Every part works, although the brakes will need to be levers rather than cables.
Self-supporting, but would shatter if sat on and ridden, hence unusable and therefore very safe.-- 8th of 7, May 29 2019 Transparent Bike https://www.gizmodo...l-transparent-bike/made from a strong, lightweight and transparent plastic called Trivex. [xaviergisz, May 30 2019] US6127505 https://patents.goo...127505?oq=US6127505Trivex patent (for those interested in its chemical composition). Serendipitously, the patent expired yesterday (29 May 2019) for anyone who wanted to make their own. [xaviergisz, May 30 2019] It could be very strong.
How do you inflate the tyres?-- pocmloc, May 29 2019 Using a glassblower, duh.-- MaxwellBuchanan, May 29 2019 Oh, and not.-- MaxwellBuchanan, May 29 2019 With the capabilities of fancy glass these days (Gorilla Glass etc), you could probably make this work (except the tyres...).-- neutrinos_shadow, May 29 2019 Lots of things are made out of forms of glass. Fibreglass - very tough. Thick rods of glass can also be surprisingly strong.-- Loris, May 30 2019 With, mostly, the index of refraction of air? Lenticular cross-section, of course.-- wjt, May 31 2019 A few people have made bicycles entirely out of wood, and I've seen a working steam engine made entirely out of glass.-- discontinuuity, May 31 2019 Found glass tires!... but they were just art.I wonder though... maybe Prince Rupert Tires?
Come kind of centrifugal cymatic configuration could confer cymmetry through chear alliteration. (why does that word 'cymmetry' cuddenly look wrong to me? two m's wtf?)-- 2 fries shy of a happy meal, May 31 2019 There are those airless plastic tires. Struts/spokes made of glass with flexible hinges could have the same action as a pneumatic tire. This new tire would still need a good material meeting the road.-- wjt, Jun 01 2019 I like the glass bike {+}-- xenzag, Jun 01 2019 Sure [+]-- doctorremulac3, Jun 01 2019 // Prince Rupert Tires //
Make the whole bike that way ... <evil sniggering/>-- 8th of 7, Jun 01 2019 random, halfbakery
