Get a good quality wider 20" rim, like the ones Ypedal has (had?) and good spokes (mine are Sapim from Grin), lace it up radial, and I doubt you'll have any issues with it.dogman dan said:Though I do love the tiny wheel, I am still concerned about the weak radial lace.
I havent', on CB2, since lacing it up radially (instead of hte half-radial with some bends before the threaded part that Justin had suggested, which didn't work out), and I'm probably working it harder than you are.
FWIW, this is the post from the relacing

and this is where I finally got driven to finish and use it

So I guess it's been in-use a little more than half a year--less than I thought, but so far still doing fine.
Though maybe not harder than you *would* if it were offroad and hardtail, but use a fat enough tire and it will still probably be ok.
I'm using the Maxxis Ringworm at something like 50-55PSI. If you don't care about power usage you can lower that to 40-45PSI and it'll ride softer.
As big as your frame is around it you an probably use a wide 2.5 - 3" moped (pirelli, shinko) tire.
