The bike I do the most miles on is the Tripster, because it's just so versatile, one of my favourite bikes ever.
The Giant hasn't been used much, it's 3 years old but I've had a series of injuries the last few years that has curtailed long rides, then we had lockdown.
The Rose is the bike I take on holiday as it's light, easy to pack down.
The Day One Alfine has literally barely ever been used <check notes> it's only done 863 miles in about 8 years, that's just a symptom of having more bikes than I need I suppose. We're moving house soon, might put it up for sale as I need the space. Would make a great commuter and it rides so well, one of the most comfortable bikes ever.
The Gocycle? Well that was a bit of a mad thing to buy, but it was a reward for something I won't go into detail on. It's an absolute hoot to ride, turns heads (if you care about such things) and you can take it anywhere. I have had it in buses, taxis, trains, pushed it around supermarkets. It's great.
