Innovative?

Its looks are 'wowwing' my colleagues into giving it a very good mark and I'm being the spoil sport because having seen alot of bike designs from the last 100 plus years, I don't think it is that 'wow'. I think the student made the mistake of pushing the frame aesthetics and not the flat pack delivery, self assembly part of his brief. I was just wondering what people thought of it and if they had seen [specific] similiar designs which I could cite. It rather reminds me of one Mike Burrows does, the name of which temporarily escapes me... ah yes, the 2D URL:http://halffg.pwp.blueyonder.co.uk/foldsoc/CRW_0163.jpg The handlebars on thta are designed to turn thhrough 90 degrees to make a narrow package which can be more easily stored in confined spaces like corridors. -- Dave Larrington - http://www.legslarry.beerdrinkers.co.uk/ A complimentary biro(tm) is /not/ to be sniffed at. |

Sean Kerslake Design and Tech Loughborough Uni Funny you should mention the iPod in your post, this looks to me like the iBike maybe.... -Overall if one picks an unusual material, then there should be some justification for use of that material that would not be practical with the usual choice. This basic design could have been made of metal and would have had all the same advantages except the looks (if it used tube metal) or the price (if it was some fancy extrusion or multiple-welded structure! $$$)... I would suggest you note the advantage of plastic over metal--that it can easily and cheaply be molded into shapes that would be expensive or difficult to produce in metal. I realize that if a working-example is required then there may be some limitations of what can be accomplished by a student for that reason--but I am thinking right off: for a utility bike, why not add an integral rear cargo rack. And the rear fender integral--that's two things the customer doesn't have to put on then, as well as two things that can't come loose and fall off. Also--since this is not a performance bicycle anyway--get rid of the wire-spoke wheels thanks, plastic 5-spokes for them too. Never break or adjust any wire spokes again, and you're getting rid of a lot of parts there for just one too. |

What about some sort of quick-release mechanism. You could use something
like a traditional bicycle quick release or something more like what is used for ski boots. This would allow for even more rapid assembly / disassembly as well as being somewhat easier. If the frame parts are high-strength plastic then they could be injection-molded, cheaply made, and basicly disposable when they wear out. Jeff |
