CityCyclingEdinburgh was launched on the 27th of October 2009 as "an experiment".
IT’S TRUE!
CCE is 16years old!
Well done to ALL posters
It soon became useful and entertaining. There are regular posters, people who add useful info occasionally and plenty more who drop by to watch. That's fine. If you want to add news/comments it's easy to register and become a member.
RULES No personal insults. No swearing.
I was sent this link...
It will have a shell of course.... and a chain or two!
Good luck to Graeme ... would be happy to sponsor in some way although this is a LaidFront bike!
According to M Burrows the drag caused by the tips of the wheels leaving the aerdynamic shell (bubble) accounts for over 50% of resistance above 80mph...
He's going to train on A78 - hope surface is good.
Inspiring chap, I stand in awe (well, sitting just now but you know what I mean...)
Hope he can smash the record, if he doesn't, it wont be for lack of effort or ingenuity, if he does, we should be having a pop sized gathering to celebrate!
Wow.
I like this quote: "You just roll it and go up through the gears. If you get into the top gear you are already doing 80mph".
Flying Scotsman's on the telly tonight.
Here is what it takes to do 80mph:
Wait for the 7 minute mark to watch a man at the very limits of his endurance.

This clip lets us see the outside and get a (too brief) look at the bike. Would love a shot in that (with weakling gearing fitted obviously :-))
Don't worry about weakling gearing Smudge - you'd be fine. You just roll it and go up through the gears.
New video of Mr Obree talking about the building process. Stick with it to the last line where you get a real insight into how much he loves both aspects of the project - building the bike and dealing with all the engineering challenges AND actually riding it. Loved that.
Another one...
This time we discover that top gear is ... 320"!!
Robert
320" :-o
Just re-checked and my Surly has 114" in top gear, and that only sees any use downhill!
Yes....
Noise is never good - is it?
Refer to Dave's look at assorted chainlines here. Yes it is inside shell and is not subject to normal laws of cycling. But.... every turn of the chain creates drag on a heap load of chain.
Chainline angles on non-standard bikes
Honza from Azub in Czech Republic makes point of rear suspension being another energy drain. At least Graeme's one is a 'hardtail' (and most other ones built for speed over comfort)
It's great to see Obree laughing his head off and grinning madly like the crazed bicycle wizard he obviously is.
And here's what it looks like on the road:

Nice bar tape :)
Have the UCI banned it yet?
yup. I hope the shell will be pink.
Hope he doesn't have to go over any sleeping-policemen, that jockey wheel sure scrapes the ground.
the linkages from the pedals to the chainring are beautiful.
More on the Obree LSR bike, on the road:
There's another video from David Street, with Obree's son Jamie taking inspiration from his Dad, but the video has embedding disabled.
He doesn't make very comfortable-sounding noises when he's riding it...
not going to make a practical commuter bike with low-speed handling like that, but can't wait to see it tried out on the straight in the big gears!
yeah it looks fast....
Can't deny that he's created something incredibly minimal. The aerodynamics should definitely be in his favour.
Definitely he's an example of the Great British Eccentric, and who can yet say if this creation is genius or a glorious folly!
Robert
Prone recumbent isn't a new idea:

Apparently not, but beware of potential school-boy giggles...
Robert
"Is the women breast compressed?" Ha!
A new FAQ might be "How is the rider stopping the passing school child who jumps on back for free ride?"
Great to see it in action at last.
I think that pedalling motion could take a fair bit of training in order to adapt to it. He's taken a lot of the circular nature of normal pedalling out of the action from the way it looks in the video.
It definitely can't be comfortable to ride but he's never let that sort of thing stop him before!
Looking forward to seeing some proper fast runs.
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.
Anyone know* what's involved to actually break the record?
Do you have to maintain the record speed for a certain time and/or distance?
Do you have to do it in both directions like you do for car speed records?
Do you have to be self propelled from a standing start?
(*'spose I could Google it, but easier to CCE it...)
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 (> 1.66 m/s) or direction (up to 85 degees either way from a straight headwind) the run doesn't count for record breakery.
2009 rules are posted here:

although I can't access the IHPVA website at work because it's blocked!
Baldcyclist mentioned this elsewhere 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 attempting to break the UK record first.
