As well as viewing daytime footage, use Youtube searches "test video", "night test video", "low light test video" etc. for any camera you buy, avoid the paid for unboxing timewasters - I viewed a lot of footage from several cameras before buying my GPH7B. I wasn't convinced by any of the motorbike side helmet style cameras I'd seen at the time, but it's been a couple of years, and there might now be something out there better than the one you've bought, for the purposes you've bought it for. Also look carefully at the product manuals for manual settings, specifically shutter speed and ISO, because they can make a dog of a product useful. You won't get manual control over aperture, because that's fixed on action cameras. Or you could go with a jawguard or helmet side mounted action camera, powered by a power bank and waterproof it all somehow?

Or go full Telly Tubby on top? Epoxy a power bank on the back or other side? Or clamp them onto the bike handlebar? Right hand side handlebar end? I've already got the mount for that. Viable probably if there's very good image stabilisation. Oodles of possibilities...
