In my teen years I'd buy a <$100 bike in the summer, keep it outside 24/7, and get a new one every 1-2 years.

Fast fwd 20 years later Ive only ever kept our bikes in a temperature-controlled garage. The garage is also my work shop, it's become a huge PIA to take them outside every time I'm doing any DIY projects or just need to access a tool on that side of the room, which is at least once a day in the summer. Even with those precautions, the bikes still get enough residual saw dust to require weekly cleaning... its a huge PIA.


TLDR... I want to store the bikes outside, under a canopy(gazebo) during July and August.


What sort of effects, (and how bad), would it be to store bikes outside during the hot months. If there is an impact, is there anything practical measures I can take to keep them in good condition without bringing them in?
