cycle weight?

[sevenhills]

My new second hane bike seems rather heavy, not something that bothers me, but how heavy is your bike?

Mine is a Raleigh Gritstone, with rack and heavy tyres. I dont have any scales, so I need to work out how to weigh it. I have just removed the deralia gaurd and I am thinking about changing the noisy large bell for a smaller one.
Incidentally, the deralia is squeeking and problably bent, I have one on my old bike - perhaps the gaurd is usefull?

Hi.

I weighed mine by borrowing the neighbours bathroom scales,and putting one wheel on at a time.then adding the two values.

My `heavyweight` is an 80s Dawes 531 mountainbike frame on 38mm Schwalbe City Jets.It weighs 31 pounds.Nexus 7, 31" to 77".
Believe me,it IS a lump!

`Lightweight`is 80s Raleigh 531 roadbike on 25mm Bontrager Racelights.Weight 20 pounds.7 speed derail-her.

Best way to weigh your bike - or anything for that matter - even your cat - is to pick it up, get on the bathroom scales and note the weight. Then get off, put the wife/child/hamster/shopping/cat/dog/bike down and then weigh yourself.

Subtract the second weight from the first.

Is your wife that reluctant to get on the scales that you have to carry her?

[Mick F]

Just illustrating a point!

Have you ever tried to get a cat to sit on bathroom scales?

+1 This is how I weigh my dogs.

I'm pretty sure the one wheel at a time does not work unless you have both wheels at the same height, ie the wheel not being weighed needs to be on something the same height / depth as the scales.

I only discovered this by comparing the results from the one wheel at a time method and MickF's method and wondering why the results were different.

Hi.

I was using it to compare the weight of one bike to another.I therefore have a comparative value,19lb compared to 32lb.

How much difference did you have between two methods on the SAME scales?

[andyh2]

Just tried it....
Me + bike - Me = 14kg
Front wheel on scale = 6kg
Rear wheel on scale = 9kg
Total = 15kg

That's only about 7% out.
Seemed more difference when I did it before. Probably because I was trying to determine the fore / aft weight distribution with me on the bike. So the absolute difference was more, but the % difference probably the same.

My touring bike weighs 30lbs (753 steel, rack, mudguards), my audax bike weighs 27lbs (631 steel, rack, mudguards) and my summer bike weighs 23lbs (Alu, no rack, no mudguards).

I use Mick F's method. I'm not sure that weighing one wheel and then the other is a valid method.

[breakwellmz]

Hi.

Well as andyh2 said it was 7% different.

As i said,i am weighing two things by the same method,comparing one to the other.

I have used fishing scales in the past the type with a spring. I now use some cheapo luggage scales bought from Aldi.
I tie a rope around the stem and seatpost and hang the bike on the scales hanging from a hook in the garage roof.
A tree branch or something else would work.

I bought a luggage weighing scale when penalties for excessive flight luggage became serious. Our luggage would obscure the window on the bathroom scales so I bought one of these as below. It's useful for weighing my cycles too.

Using Mick F's method...

just discovered my Mercian with rack and mud-guards weighs 26.2 lbs.

So now I know.

Just need to put the saddlebag back on with it's several pounds of miscellaneous bits and pieces

Other bike is in the shed and I am in my socks so I can't check now.
The Merican lives in the house of course

Principia with Dura Ace group, carbon cranks/bars/seatpost 7.4kg16.28lb
mid 80s Heswall 531ST 59cm 30 speed STI upgrade + small saddle pack, full length pump/guards (no rack) 10.9kg/23.98lb
50s Carlton 531 with 27" wheels, frction shifters no guards/rack 23-24lb
My commuter bike (modded Specialized globe pro) is around 13kg with 40L bags/rack/guards/2x front & rear lights but it does have plenty of CF bling bits on it

ATEOTD it doesn't matter hugely the weight differential of bikes, I mean unless one is competing at a high level even half a stone extra isn't really that much compared to the lump sat atop. What does make a diff is how slippery your running gear is and having correct tyres/tyre pressures.

I weigh my stuff on electronic kitchen scales that go up to 5kg (accurate to +/- 1g) when the bikes are in bits the first time after coming into my hands, curiosity gets the better of me and I have to crack them out.
Even sadder I keep a record of almost everything weight/cost/what bike etc
