They are designed by Jon Whyte, ex-formula 1 suspension designer who designs Marin bike' suspensions, and has a range of top MTBs see http://www.whytebikes.com they cost about £500 to £600 in the UK (this translates to about $900 +, but much stuff costs £1=$1 everything costs more here compared to the US ).
I am looking forward to seeing some reviews in AtoB, folding socitey and other bike mags. Has anyone here tried one yet ?
Looks like the folding bike market is getting hot !!!
