Arcane Speeder

 Antimagic Susceptibility. The speeder is incapacitated while in the area of an antimagic field. If targeted by dispel magic, the speeder must succeed on a Constitution saving throw against the caster's spell save DC or have its speed dropped to zero for 1d4 turns per spell level. 

False Appearance. This arcane speeder, which weighs 25 pounds and can be worn like a backpack, takes an action to transform into its mountable shape so that it hovers beneath you and can be ridden in the air. In backpack form, it is indistinguishable from a common tinkerer's satchel.

Flyby: The riders/speeder don't provoke Opportunity Attacks when flying out of an enemy's reach of enemies whose speed does not exceed 50 ft. 

Gunner seat. A speeder driver doesn't have to ride alone. Each speeder has stirrups that can function like an unshielded gunner seat that can seat a second passenger.

Multiattack. The armor makes two melee attacks.

Slam. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 5 (1d6 + 2) bludgeoning damage. The speeder must succeed on a CON save equal to the attack role or take full damage. It takes half damage on a success. 

The speeder comes equipped with blasters. If the driver uses them as their action, they must roll their attack at a disadvantage and have their speed halved. However, if a passenger uses them, they may roll without disadvantage and movement takes no penalty. 

Blaster Ranged Weapon Attack:+6  to hit, range 40/100 ft., one target. Hit:  (2d10) force damage.
