wayneone Posted September 1, 2005 Report Share Posted September 1, 2005 Got bored thought id weigh my bike, tried to use the kitchen scales but that didn't work >_< what do you guys use? digital scales or something? Quote Link to comment Share on other sites More sharing options...
B.E.A.U Posted September 1, 2005 Report Share Posted September 1, 2005 i kinda just pick up ther peoples biek and mine and guess witch is lighter lol. Quote Link to comment Share on other sites More sharing options...
Bucky Posted September 1, 2005 Report Share Posted September 1, 2005 get bathroom scales. stand on it, look at weight, note weight. pick up bike stand on scales holding bike, note wight, get calulator and work out hwo much yoru biek weighs. my brisa was 26Lbs.

chrishayton Posted September 1, 2005 Report Share Posted September 1, 2005 bathroom scales weigh youself then pick bike up weigh u and bike then subtract your weight from it eg you weigh 60 kilos then pick up bike and its altogether 85 kilos, 85 - 60 = 25 therefore the bike weighs 25 kilos Quote Link to comment Share on other sites More sharing options...

jamiequin Posted September 2, 2005 Report Share Posted September 2, 2005 i just done that, my whole bike is 23lbs is that good for a bike it will be lighter in a few days as i am getting a base. :) Quote Link to comment Share on other sites More sharing options...
MrMonkey Posted September 2, 2005 Report Share Posted September 2, 2005 Or you could just put the bike on the scales on it's backwheel, and hold the downtube. :) Quote Link to comment Share on other sites More sharing options...

downhill_rob2@hotmail.com Posted September 2, 2005 Report Share Posted September 2, 2005 (edited) Just hold the bike so it doesnt fall over then :) Off to weigh mine now....

zanneslover Posted September 2, 2005 Report Share Posted September 2, 2005 Just hold the bike so it doesnt fall over then :) Off to weigh mine now.... EDIT: my T-pro weight 8.5 KG ← 8.5 thats only 18lbs. You mite have swayed me into getting a T-Pro. That isn't a bad weight! Quote Link to comment Share on other sites More sharing options...
quick_spider Posted September 2, 2005 Report Share Posted September 2, 2005 8.5 thats only 18lbs. You mite have swayed me into getting a T-Pro. That isn't a bad weight! ← Sounds like the scales of truth to me :) Were the scales made by the same people who made the trials-forum tape measure? :) I'd be very surprised if a T-Pro weighed 8.5kg!

downhill_rob2@hotmail.com Posted September 2, 2005 Report Share Posted September 2, 2005 (edited) 8.5Kg is 18.75 pound. Weighed with actual digital weighing scales for weight big objects... like a newton metre.... not like your crappy bathroom stand on ones...... It isnt actually hard to get 18.75 pound out of a bike! My bike is light as fooook! EDIT: oooops, just weighed again, its now reading at 10.00KG :) :) 22 pounds. I think i weighed it wrong first time round :) Edited September 2, 2005 by terror-error Quote Link to comment Share on other sites More sharing options...
bigpimpndave Posted September 2, 2005 Report Share Posted September 2, 2005 The best way to weigh your bike would be to use one of those fish weights .you just hook your bike on and lift it up so it is of the ground :) only problem is finding someone who has one :) (by the way terror-error i don't have one) :) Quote Link to comment Share on other sites More sharing options...
MrMonkey Posted September 2, 2005 Report Share Posted September 2, 2005 that would not work, if you hold it to tight it willadd or take of weight. :) ← But if you have a brain and you hold it between two fingers so the downtube is vertical you would know it isn't adding or taking any weight.

The only way that you could get an accurate measurement in the manner you suggest is if you manage to balance the bike perfectly vertically and let go of it completely and for the bike to remain in that perfect state of balance for long enough to get a stable and accurate measurement of the bikes weight. If you are in any way holding on to the bike to balance it on the scales, and you are not yourself standing on the measuring device, then you are affecting the accuracy of the reading. If you want a reasonably accurate measurement, you could make up some structure to support the bike on the scales, maybe just a cardboard box would do to weigh a mod bike, which could balance on its sump guard... weigh the bike on the support, then weigh the support on its own... do the maths and you have a figure. This method would be a bit more reliable than standing on the scales holding the bike as any movement at all whilst on the scales can affect results.

shovel Posted September 3, 2005 Report Share Posted September 3, 2005 we used to have some scales at work with a hook that went round the bike stand and a hook that you could hook your front wheel on, that was until someone broke them . . . . anyway my bike weighed about 23 - 23.5 pounds but its got even lighter stuff on now so probably neerer the 23 pound mark, not bad for a long stock bike Quote Link to comment Share on other sites More sharing options...

I think being a pound or two out isn't anything to shit your pants about. And if you can't hold a bike's downtube vertically you must have some mental problems. If you put a tube that's say an inch bigger in diameter than another tube and weight it holding it vertically by having the tube around it I bet the weight wouldn't be much different to it's actual weight.

sfboy Posted September 3, 2005 Report Share Posted September 3, 2005 1. A bag of apples in one hand, you bike in the other 2. Add bags of apple to the formentioned first hand until balances. 3. Count apples. Your bike weighs x apples. Seriously though, I thought there was an online calculator for this sort of thing? Quote Link to comment Share on other sites More sharing options...

Maybe I should blame this on an engineering background, but I would want to keep the range of error I introduced to a minimum, which would definitely be less than the 15-20% range that you would apparently be happy with. Each to his own. :) As to your second paragraph, if I understand what you are trying to say, then again, this sleeved support arrangement would introduce an error to the measurement unless there was no contact between the inner and outer tubes, in which case you are back to the perfectly balanced item on the scales situation. :P sfboy, LOL :) Out of interest, how ripe do the apples have to be when weighing a mod bike on a tuesday afternoon if it's raining? :) Quote Link to comment Share on other sites More sharing options...
sfboy Posted September 4, 2005 Report Share Posted September 4, 2005 Why don't you try this: 1. Weigh youself 2. Hold you bike and stand on the scales 3. From a simple bit of maths ie: part 2 - part 3 = weight of your bike. Clever non? Quote Link to comment Share on other sites More sharing options...
