A lot of cycling routes are obscure and labyrinthine, meaning you have to constantly check your phone to ensure you aren't lost. While riding, and in direct daylight I have to stop to be able to read the map. It ends up taking a lot of time. I wish cities were more clear about signage. I experienced obscure and labyrinthine bike routes in my own city, and I usually bring a bike with me when travelling to other cities and have experienced the same thing pretty much everywhere.

The thing I would much prefer is clear signage. The lack of it is common.
