Does a dynamo
really slow down
a bicycle?
My impression is: yes it does.
Those dynamos must be really inefficient.
So much energy for two tiny light bulbs?
Given that the nights are longer than the days at the moment, I often cycle without daylight.
With the Dutch cycle tracks lighted, I doubt the advantage of the tiny headlight.
- Does that bit of light really counter balance the heavy cycling?
- Why does the light dim when I stand still?
- Why is cycling harder the only way to get more light?
And... why should a dynamo slow down my
horizontal
speed?
The speed I would like to get rid off is the
vertical
bouncing.
Idea: bouncing dynamo
Bicycle dynamo's should
- be mounted
below the saddle,
- with a smart spring mechanic,
- that transforms bouncing into electricity.
Advantages
- The dynamo slows down the bouncing, a yet unknown increase of comfort,
- Need more light? Bounce harder!
- Need light during a standstill? Bounce!

next week,
