Duplex

A powerbank has worked for me

The footage was very good quality Gopro 6 was more than enough for me Had it mounted on a chest strap, didn't notice any vibration on footage Would prefer a helmet mount POV, but can't use a permanent solution when renting helmets.. Sorry for very late reply

I bought a Gopro 6 Black, will just have to test it out to see if I'm happy with quality

Thanks, will keep that in mind Would something like a Gopro Hero 4 be to "old", or will just about any of them give decent quality video?

I love to rent bikes when travelling to sightsee, but I would like some POV footage.. I'm not looking for a top notch camera to make youtube videos, but still want quality footage. I'm considering a second hand GoPro camera, preferably (but not necessary) with 4k capabilities. I'm not very updated on the camera tech stuff, would love some advice
