Thanks for the tips.
Going to get two Ez Anchor Toggle Bolts for 100lbs which actually provide up to 180lbs.
More than enough for 25lb.
This is for an entryway in a condo (minimalist) so dry wall anchor only way to go.
If anyone has gone this route and still had the bike rack fail please let me know! I just don't understand the risk of a 25lb bike on a mount that can hang 180lb on dry wall.
