Missed this thread initially. Good to see that DiS continues to be incredibly conservative about non-motorised forms of transport.
I’ve got a push scooter. Comes in handy for short trips, plus the kids like to scooter to the park/library/swimming so it’s nice to be able to join in. Has come in handy a couple of times also with tricky parking - drop the family off, park a couple of miles away, grab scooter out of boot and roll back. They take up very little room when folded so convenient to have around the place.
That said, obviously a bike has much greater range/flexibility. But then again, why not both?
