I don't know (sigh) what is crazier: carving on a lap top cover, or cycling 25 K in 30+ temperatures.
I think my son is crazier still, he's gone though SEVEN E-bikes, in about as many weeks. He is currently delivering food, and doesn't like using the break (to save time, like a real dumbo). Good think he rents (and they repair for free, indefinitely it seems) but he'll never develop a special loving relationship with his bike like that, and this may be the cause of many accidents (the rough treatment).
