You can do it Charlie Brown!
With all the great stuff people build here on MB.com, wheels should be no problem for you guys/gals.
If you are a bit mechanically inclined building a wheel can be done.
My first front wheel took me 3 times to complete.
MP3 was super easy because of the radial lace pattern.
Most hubs motors only really need 1 cross and that's real simple too.
Its the 3cross that starts to get a bit busy.
It gets easier the more you do, just like most things.
Take your time don't rush it, evenly tighten the nipples, count the turns.
I go 3 turns. Have an example on hand.
Not to sure its any cheaper, at least for me. I like to use somewhat good quality parts. Butted spokes are $1.00 each and double wall rims are $30-$70 or more, plus the motor/hub used.
Spinningmagnets started a thread on ES for building wheels.
I thought you got super powers from a lightning strike to the head.
If you could channel that power into the hub....
J/K. wow SB lucky to be alive!
