Looking at this post and the picks you posted, looks like you'll remove the fixe sprocket, slap on the 44T standard motorized bicycle sprocket after the center hole's been enlarged, and then put back the fixe sprocket. Do I have it correct??
I've got one of these fixe bikes on layaway and will be tackling this soon. Any insight is appreciated. Also, how do you go about enlarging the center hole on the 44T sprocket? --- Thanks
