My experience echoes yours. I love biking to work, especially with an e-bike, and I normally did it five days a week, I even started blogging about my experiences[1]. With the right gear, cycling is really practical form of transport for me to completely avoid unnecessary covid risks on public transport.

Now with lockdowns, I'm not biking nearly as much, the weekly five-a-side football is closed, there's nothing open, so little motivation to walk around town, and so on.
