Now I've seen better images, it's more of an aerodynamic "mermaid's purse" </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=6432#post-83917 Fri, 07 Sep 2012 19:50:14 +0000 Cyclingmollie 83917@http://citycyclingedinburgh.info/bbpress/ <p>Baldcyclist mentioned this <a href="http://citycyclingedinburgh.info/bbpress/topic.php?id=8380">elsewhere</a> but without the magic word Obree I missed it and so I thought I'd bump up the earlier thread about his record attempt. He's now <a href="http://www.humansinvent.com/#!/8856/obree-set-for-land-speed-record-attempt-in-great-britain/">attempting to break the UK record</a> first. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=6432#post-76904 Wed, 04 Jul 2012 15:07:36 +0000 Arellcat 76904@http://citycyclingedinburgh.info/bbpress/ <p>Standing start with no assistance other than being held upright and pushed for up to 15 metres. About a six mile run-up to a flying 200 metres, one way. If the wind speed is out of tolerance in speed (&gt; 1.66 m/s) or direction (up to 85 degees either way from a straight headwind) the run doesn't count for record breakery.</p> <p>2009 rules are posted here:</p> <p><a href="http://www.wisil.recumbents.com/wisil/whpsc2011/TEAMinfo09.doc" rel="nofollow">http://www.wisil.recumbents.com/wisil/whpsc2011/TEAMinfo09.doc</a></p> <p>although I can't access the IHPVA website at work because it's blocked! </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=6432#post-76895 Wed, 04 Jul 2012 14:43:35 +0000 cb 76895@http://citycyclingedinburgh.info/bbpress/ <p>Anyone know* what's involved to actually break the record?</p> <p>Do you have to maintain the record speed for a certain time and/or distance?</p> <p>Do you have to do it in both directions like you do for car speed records?</p> <p>Do you have to be self propelled from a standing start?</p> <p>(*'spose I could Google it, but easier to CCE it...) </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=6432#post-76889 Wed, 04 Jul 2012 14:25:01 +0000 Arellcat 76889@http://citycyclingedinburgh.info/bbpress/ <p>It doesn't have to be comfortable, but it does have to be efficient, since you're only on the machine for about eight minutes. I daresay Obree is no stranger to feeling a little worse for wear on his bike from his hour record days. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=6432#post-76887 Wed, 04 Jul 2012 14:19:34 +0000 Bhachgen 76887@http://citycyclingedinburgh.info/bbpress/ <p>Great to see it in action at last.</p> <p>I think that pedalling motion could take a fair bit of training in order to adapt to it.
