It was a few years pre-pandemic since I regularly bike commuted, but as others have said the big change I notice is the number of ebikes and scooters. I park and cycle my commute, and I’m quite tempted by a rear hub motor tbh - thinking of human power in from further out, and then motor on for home in the evening (predominantly false flat uphill into the prevailing wind). I’ve seen quite a few posts saying that lots start with this intention, but the weight and drag means it doesn’t happen. I do find the evening spin/ double day takes more out of me than a spin of the same total distance.
Someone mentioned Dyno hubs earlier - definitely the best addition I’ve made. I brought a full wheel from bikediscount, and a B&M German standard 100 lumen light. Adds a bit of weight and drag, but throws out great light in an appropriate patten, and never a worry about batteries/ charging lights.
