Why is my object not moving?

So, I am making a game that involves a floating jet bike made up of an empty parent with multiple objects and a camera as children. All colliders are enabled. All rigidbodies are kinematic(except on quads). I was trying to solve a collision problem by switching to using forces, now I have a movement problem, as in not being able to move, period.

using UnityEngine;
using System.Collections;

public class PlayerController : MonoBehaviour {
	public float Speed;
	private Rigidbody rb;
	void Start()
	 rb = GetComponent<Rigidbody>();

	void FixedUpdate (){
	float moveVertical = Input.GetAxis ("Vertical") * Speed;
	float moveHorizontal = Input.GetAxis ("Horizontal");

hi initialize the speed to an initial value at the beginning of the script speed = 10f;
or more and increase it in the ispector if necessary. multiply speed x time.deltatime. do not use isKinematic. Should work
