your plans or riding style , is unstated..

I have 28 spoke wheels , but they are 406 20" (2 on my bike trailer )

and a 16" on my Brompton.. (I have the original & one made around a Schmidt New XS dynamo hub..



8 weeks? you ordering from Asia? bring as you say, cheap ,
that the case why not just get a shimano dynamo hub wheel off the peg
with a rim of modest cost like Sun CR18?



good luck..
