I parse this as.. the bikes grow, right?
@internetsdairy of course you are right. as a side note, I think brands deliberately use language or phrases that hover on the edge of being "wrong" in a bid to get noticed and spark debate.
@Spine_Sideburn They do, you're right. My guess in this case is it's unintentionally a bit shonky. Anyway, why am I trapped in my house by a BMX that's rapidly filling the hallway?
@internetsdairy I stupidly exchanged my larger children for smaller ones. Now I have huge bikes none of us can use.
