btw, check this out:

at first glance it looks like a dahon dove.



the mono fork and mono rear triangle enable a super compact fold.



external cogs and derailleur moved to the inside. 7, 8, 10, 12T four speed with 52t chainring.. wow... i've never seen anything like that..



these vids are funny and charming. the bike has some issues. but, i think it's under development. currently it weighs 11kg. not bad, but i think it could be reduced further. im willing to bet that the fork is high tensile steel. could be sleeker and fab'ed from cromo. also, the seatpost is too short even for the guy riding it in the video. needs to be 600mm althought that will affect the compactness of the folded package. the post diameter is 31.6mm. a 600mm brompton cromo post could be used.. nonetheless, a very cool project.


the mono fork and rear make tire changes super simple:


fun for the whole family and all the bikes fit in the boot no problem:
