My boss somewhat “okayed” me to park a small bike either downstairs by the elevator or in the larger room upstairs.

Now the question I have for all the Oppo’s of the bike variety, is a Grom a good buy for my situation? My round trip to work is 7.5-8 miles, max speed (legally) is 35, it’s all through the suburbs basically. I can’t really get anything larger than a Grom/Z125 as my boss would say “No...park outside.” Worth noting, parking outside isn’t really an option as I’d either pay to park or have to park far away for free.
