Using a DYNO generator for lighting

[Henshooter]

Hi all , was wondering what your take is on using a dyno for lighting on a motorised push bike
The issue I have is in general you ride a normal bike at say 15-20 kph so the dyno produces enough voltage to light up the front rear lights , whereas a motorised would go 40 kph , now would this produce to much voltage and essentially blow the globes
As well would it cause vibration and mis balance or wear on the tyre.

I ask because I love retro ,and as such have found a great retro dyno kit I would love to fit to my cruizer but don't want to spend the dollars to see it fail from over speed
Here's a pic of the unit I'm looking at
Any advice would be greatly appreciated

I've never heard of a wheel driven generator lasting long under motor abuse. Too fast.
Maybe you could make some kind of high-voltage cutout or protector to keep it from overspeeding?

I wonder if you could install a bigger contact wheel to slow down the rotational speed?

Problem there would be if you were travelling slow, they hardly produce anything below 10 Kph as is.

That sounds like the most simple answer to this problem that I have read yet.

Use a belt drive alternator with a cvt pulley to adjust speed according to load while riding....?

Henshooter, I am running a front wheel hub that kept blowing bulbs till I made a charger to charge the battery while running the lights at a constant voltage. Check out my thread located HERE.
