My big hope is that I am transferring a bit of an appreciation of "normal" bikes to them--pre-compact frame size and geo, rim brakes, side pulls or cantis, non electric, rigid, steel (to the extent possible --most little kid's bikes are aluminum today, and i will admit the modern kid's bikes are better than their vintage vorbrearers). Sure, those are my things, maybe they won't be theirs. But if they feel confident adjusting a canti, then they are a few steps ahead in terms of mechanical self sufficiency.
