Survey New Dynamo Dt

Hello everyone, I am promoting this small survey regarding a new dynamo for bicycles and I would kindly ask you if you can take 1 minute of your time to answer the questions and if you can pass it on to your friends as well. Thank you very much everyone. Davide

1) If you ride in the evening, do you turn on the dynamo?

2) If no, why?

3) Is there a new dynamo that, with moderate effort or even no effort, allows for daytime charging of iPhone cell phones and electronic control at night for the front headlight and rear position LEDs, completely eliminating the use of disposable batteries?

4) If it were available on the market, would you buy it?

5) Would you spend up to 50 euros for this dynamo?
