Cross posting between mastodon and velocipede salon:

I am looking for a #dynamohub for my daugher. She is riding a #folding bicycle with 20inch wheels.

So my question is:
- are their #dynamo hubs designed for smaller wheel sizes?
- is their a model I should look for in particular, to optimise for a decent lightning/drag ratio between 10 to 30kph on small wheels ?
