• The dyno hub will be fine, built loads like these. Get yourself a 32h shallow rim, so the angle of the spokes is not as severe. Build it 2 cross for the same reason. You can also get the smaller Sp dynamo that's specific for small wheels.

  • ah brilliant, those are great tips, cheers dude.

    Any ideas of what sort of rims to look at (my knowledge of 20in / bmx rims is v limited) So far i looked at the Halo T2 and Halo EX3.
