bike weight

[deptfordmarmoset]

I think 15 and half kilos is quite substantial for a bike.
By comparison my Tarmac and Venge together weigh less than 15kg

And that's with you on them.....

My Vivente tourer is 15kg, and with the seat post mounted bag about 16kg. I'm used to riding it up hills. I did notice the difference when I got my first road bike in November, though.

is 15 and a half kilos very heavy for a bike? (hybrid)

Not as heavy as my Mrs. Doubtfire, 19 and a half kg
No worries Steph, on Boris the 15.5 kg hybrid I managed (just!) a 17% hill

My touring/hybrid bike, in road-going trim with mudguards, lights and rack, is 15 kg. Add on 75 kg of me plus clothes, and 5 kg of even the most basic day ride/commute luggage (tools, pump, jersey, waterproof, in pannier) and you have 95 kg. Cycling at say 150 W up a reasonable hill of 5%, spreadsheets suggest I would do 5.7 mph. Suppose I lightened the bike by a massive third to 10kg. My speed would increase by 4% to 5.9 mph. Make the gradient half that, 2.5%, and the gain in speed is only 3%.

Every gain is worth having - but in my opinion, differences in weight are likely to be less significant than how rigid the bike is, what sort of tyres it has, and whether it encourages an aerodynamic posture. Plus, there's the incalculable factor that a light bike might well encourage you to work harder. A traditional touring bike may weigh the same as a cheapo gas pipe job, but would be a much easier ride, despite the weight, because of those other factors.

What is the bike? If it's a racing bike then, yes it's very heavy. If something like a tourer with mudguards & rack it's not too bad.

My knockabout bike, on which I've recently ridden the Hardknott and Wrynose passes is 18kg unladen, so I'd be quite content with something that weighs around 15kg

granny ring perhaps?

It's not a bad weight for the money. My wife's pinnacle hybrid is just under 13kgs and was £500. Dont forget tyres are important too in the rolling of the bike.

granny ring perhaps?

Yes, I had a 20" granny gear (28t front 34t rear) which worked over the passes. I've changed the gearing in the last couple of weeks but it still gives me a granny gear lower than 22", which should get me up The Long Mynd.

Big Bertha is 20Kg, but then as I also have the trailer & a 3 y/o attached and spurious stuff in carriers weight is not so much an issue with the bike
