I would love to read what are the best tricks you learned in your commuting experience.
I would like to propose a format, where we use one comment for each single trick/suggestion, so if you have multiple tricks, post multiple comments. This would allow upvotes to create a ranking of best suggestions
I will start with a couple of tricks from my experience.
Bone conduction headphones are great for getting some quality podcast listening done during your bike commute, and since they block out no sound at all and don't cause problems with sweat, they are ideal for on-bike listening.
I'm not even sure that I would be commuting by bike without a pair, they make it so much better. 2 half hours with podcasts per day? Unbeatable.
if you commute regularly at night, opt for a dynamo hub and fixed lights : no need to worry about batteries, no ninja mode !
I've had those magnetic lights, it is just ok to be seen (thanks to reflective parts) but useless if you need to ride in the dark (I have some km outside the city with total darkness). I don't remember why I wanted it so bad, maybe a pimpmybike mood as I had a dynamo hub on this bike, but now I won't install it on my bikes. Apologies if I broke your mood, I would recommand to save for a real dynamo hub + lights :)
Visibility is the most important thing for safety. Staying in a consistent lane is better than staying to the right because of this.
There are normally usable bicycles which can be folded into ~suitcase size in <20s and then be taken onto most transit as luggage. Usually quite a lot more expensive than a regular commuter bike but extremely practical.
