I ride with my MegaVolt + O-Atty. That said, I don't really ride long distance, all weather so that's that. Though if I plan to I'll just ziploc my Mod and juice just in case.
And while reg Mods aren't really weatherproof, Mechs aren't either and water going into tube (which will happen) are a surefire (pun intended) way to short curcuit your batteries.
HOWEVER, it's admittedly much easier to put a few orings or pipe tape to help "seal" a mech tube then it is to completely gasket a reg mod so that's that. Also, with a 18350 mech +
a tiny topper (and a not too ambitious single coil build), you've got yourself a decent tiny mod for outdoor purposes.
Heck, a 18350 mech with a Taifun GT was my PRIMARY mod for the better part of 3 years lol:

As an alternative, there ARE reg Mods out there marketed to be "waterproof", though the veracity of such claims remain to be proved lol.
Finally, check out the Cync or MyJet. They're both really tiny, and with a decent 24mg juice (the pods are refillable) they should be fine for nic delivery, even if they would still need a ziploc as they're not waterproof per se. As a bonus though you can Vape either one WHILE riding thanks to their auto-switches.
Here's my Cync sandwiched between my other "main" Mods for comparison:

Ahhhh… zip lock, if all else fails, zip lock to the rescue

18350 is definitely a good idea…
High ohm single coil seems inevitable to conserve battery andjuice.
Taifun GT look like a huge capacity. But carrying glass tank running around crips me…
From my not too extensive experience, not all Atty are thirsty, some 2ml tank can last longer than 4ml tanks… My serpent alto drinks a lot faster than my (now lost) le magister… are there other slow sipping Atty out there?
There are really very little storage space on a bicycle, will avoid spares and juice bottle if I could.
