....Specialized P.Grom (also marketed as the P.20 Grom in some years/regions). This was Specialized’s entry-level 20” freestyle/park/street BMX complete, aimed at younger or smaller riders (roughly ages 8–14 or heights 4’5”–5’4”). It was part of the P.Series line and produced roughly 2014–2019 before being discontinued.
These are legitimately good starter BMX bikes... Much tougher and better-riding than big-box store bikes.

It’s a solid, tough little bike that’s perfect for learning barspins, manuals, and park riding. Not pro-level (no full chromoly, heavy-ish), but way better than department-store stuff and still very rideable/upgradable today.
Just got it back from the TREK bike store here in Westminster for a tune-up and new chain.
