12 watts, really?

[Pure Savage]

Well let's conduct an experiment to see if the movement of chain links has any bearing on power required to turn pedals; Go home, lube your chain with super glue and come give feedback on how that worked out for you.

We want a video feedback session tomorrow, save the proper maths till Friday.

Hmmm, not quite sure of what you're suggesting. But let me try it this way. Consider a single speed, so chainwheel, chain and sprocket. Apply power, or energy in a fixed time, on the chainwheel and the chain will at least bend and straighten as it travels round the chainwheel and sprocket, yes? So there's energy required to do this? Lost energy (or power). You can hear the chain running? So mechanical power has been converted to sonic power, again a loss. Etc etc. The end result is less power arrives on the rear axle than was applied on the chainwheel.

 

Edit: take this a step further. Dry, unlubricated chain, sounds noisy? Lubricated chain, preferably not with Superglue, sounds....less noisy! Lube reduces lost power. Scale-up with more chain bending and straightening round jockey wheels, more lost power.

Ah, makes sense now.

 

Energy lost during the bending and sound. Which in effect becomes power when the pedals are turned.

 

Thanks

If this moves me from 29875 place to 29870th place at argus I am in.

 

If this means it will give me 12 watt for nothing while cycling through the Karoo in December, hell sign me up for 2!

OK that's my 12w's sorted with the #BenOiler (Pat Pend) ... Will test tomorrow, fine tuning may be needed ????????????????????

 

Slowbee you can be a 'brand ambassador' if you like ... Half price to you then!

I've tried that line too, but they keep saying it's sore.

Well put and I would agree with that wholehearted, I guess as an 'average Joe' myself I am merely looking at it from my point of view ... I still think that many "average Joe's" will go out and buy it regardless?

 

Rather just use water on the chain, instead of investing in expensive lubricants and causing global warming....

hold your horses here chaps ..... are you saying more noise means power loss ?

schweet! packaging will include tape? or is that a "hidden" extra?

 

I'll need one for argus to test.

When i first saw the thread title, i was under the impression that it had something to do with led lights. But now i see this. Do you guys measure performance in watts? How on earth do you even do that?

 

Gosh its been years since i really rode a bike...

(dare I ask)....what's your point SB?

Watt measures Power output, be it mechanical or electrical.

 

NotSoBigBen is that system activated with a kick?What Happens when you got exposed cables running on the downtube?

By the nature of power transfer everything is a loss.

The chain gets hot as it turns causing some loss, friction between the chainrings and the chain cause loss of power(please remember that this friction is required for the system to function).

The torsion of a drive system on only one side could potentially cause a loss due to the compensation for lateral forces.

You mean a bike with GEARS? Mon dieu 'fokus my kind'! This system is designed for hardcore riders not fun rider types demmit .... it is gravity fed, one must however remember to replace the end 'prop' else one may find a puddle and empty bottle in the morning 

 

As an aside I did test it this morning and man was I FASST (apologies to Ivano) but am unsure whether it was the #BenOiler, the yellow nasal stretcher or the powerband keeping me in that super quick upright mode
