I have 2 doubts and would like to listen your opinion. 1) I have seen some python with handlebars below de seat. Maybe because it help the beginners. Must I welding it on the front side or on the rear side? 2) About the point to put the seat, or put the CG of the seat. Must I to try welding just over the pivot table, correct?
