I'm not sure if anyone's mentioned this item yet, but I've been resisting a strong and irrational urge to buy a Boosted board electric longboard.
There are already seemingly infinite ways for me to get around my city, including: walking, scooter, car, bus, subway, taxi, rideshare, personal bike, city run bikeshare system, and countless private dockless bikeshare systems, but none seem quite so fun as cruising uphill at 15 mph on a longboard.
I've been trying to hold out until winter, hoping the craving will go away once the weather turns. But I'm sure I'll reward myself for holding out by buying it in the spring :)
