[kloofnek]

Someone was telling me that once upon a time,one could have a little gadget attached to a bicycle frame which when you rode it,it touched the wheel and caused fricton which lit up the cycle light on the handlebars.

Has anyone heard THIS before!!!!

I had one.It was a knurled wheel which touched the wheel.

This is a leg-pull, isn't it?

[AB Editor]

Yep, used to be quite common - but it's not really that good compared to the quality of battery powered lights now.

Fun fact: You're required to have one in Berlin because batteries might run out. Most just ride around with one attached, but not "engaged" :)

[AB Editor]

I wondered that Svejk, but gave the benefit of the doubt....

Got one on my Mountain Bike, very effective

[Everhelpful]

They have been around for 70 years at least.!!!!

[Prudie]

If you don't have a real one you can pretend you do by pegging some cardboard on the spokes so it makes the noise :-)

[vulcan42]

Wasn't there another version that had a dynamo built into the front wheel hub?

[Frank97]

Yes, I used to have one of those, until it got nicked.

[kloofnek]

wow...so may answers,I really thought my friend was talking through his hat...surely,I thought, something like this belongs to the Victorian age!!!!

[mazie]

LOL...and here's me thinking that's how bike lights still worked !

[boxtops]

Yes, absolutely, I used to have one - it's not that long ago!

[Old_Geezer]
