I did test some of my (new) gear on my weekend tour. Here are my thoughts:
Back Panniers: They worked well, very spacious, and stayed in place. Just like panniers have to be. (Aqua back plus by Vaude)
Solar Charger: I had them for the way there and back on my rack. Friday it was mostly cloudy, but Sunday it was really sunny. In total, I got enough energy to charge my headphones, my camera and 50% of my cell phone. Not great and not bad. (by ADDTOP)
Seat for Button: The seat, in general, I like a lot, but I will need to add a neck pillow for Button since his head is falling down to the side when he wears his helmet. (bicycle seat for baby born puppets)
Carrying strap: Worked well to get Charlotte up and down the stairs.
Headphones: I really enjoy being able to listen to music now while bicycling, they work well, and I still can hear everything around me. I sometimes struggle with them, when I want to cover my ears as well, to keep them warm and then they press against my skin or ears. (AfterShokz Air)
Bicycle cap: Felt great, kept the head warm enough, shielded the eyes. (fabrics via Spoonflower)
Handlebar Mount: Stayed in place and held the camera in place. The turning around worked well, I am currently working on the video. (by PULUZ)
I hope you all stay safe, kind and healthy!
keep exploring and smiling
