the stock 9 hole bolt pattern will not work! I have 68 spokes on my cruiser and I went to a 36t sprocket ( made my own). I instead drilled 8 holes so I can tighten it down easier, However before I drilled my holes I put the sprocket to the wheel and marked in between the spokes where I wanted a bolt, and tried to keep it symetrical 8 bolt. then I had to make the plates and rag joints for the sprocket. took some time but it works!

what will i get into mounting a kit sprocket to a 68 spoke wheel , will it fit with a bit of work
Wayne is right, math is the thing here since 68 is devisable by nothing as far as a hole pattern. I machined an adaptor to work but it was really time consuming, and you can see by the picture I still had to actually bend a couple spokes to clear the bolt pattern.
The old 36 spoke wheel is the best way to go although I will admit the 68's and 72's are pretty cool looking.

No one mentioned welding which admittedly requires practice - but as for mounting an engine to your bike...
We've about 14,000 members that would argue with you about that lol

CreativeEngineering apparently makes a sprocket hub adapter that PirateCycles sells for 68 spoke Micargi's.

HI All,
68 spokes should not be a problem....Just need to see one once...
FWIW we can make adapters for most any wheel....
Here are some pics of a Super Sprocket we made for a 140 spoke wheel! (we have the pattern on file so we can make them as needed).
We can make sprockets two different ways...
One sprocket will mount to hub (if your hub is a high flange) but you will have to drill holes in the hub...This provides a solid mount....IF you can find a disc brake hub with enough spoke holes you can mount the sprocket directly to the rotor location itself or with a Top Hat Sprocket Adapter.
The other sprocket (one that looks like a hollow ring) is clamped to the spokes with a machined backer plate (can hard mount to clamp spokes or possibly use rubber like the factory kit (rubber not included).
NOTE: The first sprocket would probably work the best BUT we can close up the center on the sprocket that looks like a "ring" BUT The customer liked the "openness" of the sprocket... On the other hand we could have added lightening holes to the solid sprocket BUT the customer wanted it without them....
Hope this helps...
Andrew
PS - After working with this wheel for awhile a 36 spoke wheel looks like it is too fragile to work!! HA

Hi guys,
Here is the sprocket from Pirate Cycles that works with the 68 spoke Micargi wheel. This sprocket acts as your dustcover and connects directly to the flange of the hub. The allen fastners used for connection are countersunk flush to the sprocket, therefore the brake arm needs no modifications at all, "nice". Nylock mounting hardware is included. I have a quantity order in that is due to arrive before Christmas. We will update our site upon arrival.
Thanks,
Justin
