I did a little googling this morning and the consensus is that 55 gear inches is a typical BMX bike. Weight is typically 25-27 pounds. But I think that was with 20" bikes... I see that in competition, 20" and 24" are the norms... it seems. 26" is more of a cruiser. I wonder if 22" is a thing or not... But I think I'd like to do a 24" build with a bit lower gear inches than my cruiser. Mine is at like 62" approx..... I forget exactly what it was when I figured it out but it's close to that. The only thing is I think I'd be pedaling a lot more to cruise around with the family if I go that route. Either that or I just have two bikes. A normal 20" bmx and leave my cruiser as it is for riding.... But I like the idea of making an "ideal" hybrid bike. There's probably not such a thing though.
