    20 inch (451) v. 20 inch (406)

    I am considering purchasing a 20 inch wheel bike. Some come with the 406mm diameter wheel and some come with the larger 451mm diameter wheel.

    Is there any great advantage or disadvantage to one or the other? The only one I see is that the 406 tires seem to be a little less expensive. Does anyone know if one standard or the other is being phased out of production?

    Thanks for any help or insight

    BMX race bikes come with the 451 (20 x 1 /18 or 20 x 1 3/8). BMX freestyle and dj style bikes come with 406 (20 x 1.8 - 20 x 2.3, generally). Neither standard being phased out.

    Are you talking about a folding bike?

    If so, the advantage of 406 is a much wider array of tires.

    451 has a lot less tire availability. But, the tires that are available are generally a lot skinnier.

    I switched my bike Friday over to 451s- so far, it's been pretty nice. Changed the handling a bit but in general it was a positive change.
