I had to go and buy something and so I hopped onto my #bike and made sure that I had my #BikeLock with me. Got to the shop, only to realize that I'd forgotten the bike lock keys! They're on the same keyring as my car keys and separate from my house keys. I could have risked popping into the shop and hoping that it would be ok but there was a fellow #cyclist who had also just arrived. I asked him if he wouldn't mind just looking after my #cycle while I was away for two minutes. Happily he agreed and we parted with a friendly farewell. It is nice to have #civility confirmed in daily life now and again. #CyclistsHelpCyclists

I often like to do thought experiments while #cycling and sometimes I can't think all the way through to the end of the answer. Here's a recent one for #physicists who specialize in #relativity. A #bike's #wheel rotates such that the bit in contact with the #road is instantaneously at rest with respect to the #ground (as long as you're not skidding), at least in #NewtonianMechanics. On the other hand, the bit diametrically opposite to it is moving at precisely twice the speed of the #bicycle.

Now, imagine a #cyclist with the speed of #Hermes and the strength of #Heracles who can go as fast as possible but within the confines of what we know about the real world. If the above still holds, about the #tyres of the bike, then, in the limit, the top of the wheel can go no faster than the speed of light, c, and the mass of that bit of the wheel increases without bound. Does that mean that the bike itself cannot exceed c/2?

Hey everyone, I’m #newhere. I’m interested in #ajft, #cyclist, #melbourne, #monkeyhanger, and #sysadmin. Thanks for the invite, @Welcome Diasporg! As with many others, an ex-joindiaspora account, frantically trying to match up with previous contacts prior to 2022-03-01

It's an almost perfect day for #cycling, with bright #sunshine but a bit of chill in the air so that you don't sweat very much. On my #cycle trip, I passed a man riding a #tricycle and noticed that he only had one leg. He was managing quite a respectable incline and so kudos to the fellow #cyclist.
