hm, didn't see it from that perspective yet.
my brother told me that its probably about using the lower ends of the handlebar, which reduce your cw-value
first met this article mentioned on copenhagenize.com, who tried to leverage it as a point for:
"commuting with your short john in your work clothes gives you the same time as commuting with any sorts of roadbike wearing lycra"
which definitely wasn't the point, since that guy rode a roadbike both times, a carbon ultra modern one, and a steel roadbike from the late 90'ies, which most probably has just 2 gears less.
Calimero with Sombrero.
I've seen several accidents where the head was broken, and the helmet not touched.
its just of use if you jump directly upwards into the ceiling.
Heh. That's about the sum of it. :)
Oddly enough, I was thinking about something like that a few days ago. A real breakthrough would be to develop a way to directly convert the energy stored in one's body to electricity, for powering cell phones and computers and such. Most of us are carrying around a bunch of extra stored energy that we don't really want.
(Yeah I know, hand cranked generators etc. etc. I'm talking about a way to do it at the molecular level without all that.)

Maybe the silver surfer finaly got us?
whew. these guys are doing realy hard.
its gotta be more than 130 rpm in that training gymn...
just started the roadbike season by a 45 km trip (~30 miles) with some neat uphill riding included.did a real good job. the headlight sort of was earlier done than me ;-)
oh, and btw... once you do more cycling, you start changing parts wearing off (or just becoming replaced by technical superior stuff) on your first bike, you can put that on your second (sort of similar) roadbike.
so most probably the 150$ he mentiones for the steel bike are no realistic number if you'd like to get the same in 'new' state.
Most probably getting such a bike will cost more than 1500$
- lighter (reduce bike weight by 1kg -> 1000$ when you start out with a $800 roadbike of 10 kg)
- more dureable - parts will last longer
- better adjusteable - tuning the hickups out of an expensive bike usually takes less time
- more reliability - parts less probably will fail on you
- more effective - you will get more of your force to the road
hm, read this comment about commute time with two roadbikes:
@Finbar do you mean "it _wasn't_ a scientific piece" ?
Anyway here's some figures from bike calculator, gradient zero
Rider 1, 70 Kg, Bike 7 Kg, 300 watts --> 36.99 kph
Rider 2, 70 Kg, Bike 11 Kg, 300 watts --> 36.90 kph
There you have it, a small difference in weight makes hardly any difference. But change the drag by placing rider 2 on the "hoods"
Rider2, Bike 11 Kg, position on the "hoods" --> 40.01 kph
what does 'on the "hoods"' mean here?
why in some cities girls ride bikes (germany) and in some they don't (gb)
Despite what They say, you can totally forget how to ride and it's kind of terrifying to try to relearn as an adult. =)
Mo Okt 25 2010 08:22:38 EDT von IGnatius T Foobar @ UncensoredThat's awesome. I'd love to be part of a big bicycle commuting community.
What's the average distance travelled by those folks?
They probably do ~1 - 6 km which would be around up to 4 miles?
my daily commute is 20 km (~12 miles?) each.
this guy is bike commuting new york:
nice movie also, interesting to see the different ways of road layout etc.
nice campaign from some german towns: Turn on your brain, turn the engine off:
sadly haven't been in any of these cities last year :-(

You operate this bike by pulling and pushing the handlebar:
They have rides during the week and weekend mornings.
They're all over westchester.
Was that just an urban legend?
The goofy thing is it doesn't attch to your bike, but it's something you step on, so you still have to put all the energy into pushing your bike with all the weight on one leg. Why not just something that pushes the bike?
Pretty darned close. Not $400 close, but they are powerfully nice units (Garmin Rino 530HCx), and have built-in weather radios and transceivers for use as backup comms.
Unfortunately, the chargers they come with are very poorly designed and break very quickly, making it impossible to charge the battery packs (which do last a long time). The AA adapter packs don't last nearly so long and are bulky.
Like, maybe, this one?
animal, ain't your bike missing something?
my tandem is used by more than one set of drivers, and depending on the persons shoes/preferences its switching to...
- plain old platform pedal
- plain old platform pedal with straps
- Schimano SPD
and all that depending on who is sitting on which saddle...
So an easy & quick change of Captain and Stoker isn't possible without getting out the inbus key, the 14mm jaw wrench (depending on which pedals you've got) and screw them off and on again.
Most probably the primary target for that sort of thing are bikes that are ridden indoor for training of bike clubs, so everybody can bring their own pedal and exchange / adjust the bike quickly between several members of the club...
