Hi, I am trying to design an electric scooter, in a lot of ways similar to link below: http://www.letskickscoot.com/home/articles/scooter_stance.cfm For an all electric vehicle , I am guessing stance 1 would be similar to braking, and stance 2 would be for an accelerating vehicle's frame of reference. I am trying to figure out what percentage of body weight goes onto the handle. Assuming the CG is approx the same height as the handle holding position? Can any one help me understand the forces and make an FBD, I will post my FBD soon. Thanks in advance.
