Madwagon crank size

[Mlamey]

Well my cranks going bad because my chain was too / is too tight. So I lost the back rim it was bent and I moved and left it and the voodoo chain guard and fenders behind. . And I'm using it as my daily driver. 8 miles down the 301 at 28mph max average 22. So I need the crank size without taking in apart yet . Am I dreaming? Shop has to take out and order one . Camera is outta wack but here's some pics. Need rim suggestions and crank bottom berring bracket , lol y'all know what I'm talking about.

The crank length should be stamped on the inside of the crank arm somewhere,usually up near the pedal. The width of the bottom bracket shell should be either 68mm or 73mm. That you can measure without removing anything, but the length of the spindle would be best guess without removing the crank arms.
