Healing on Bikes or while flying?

[AlexP_P]

this is one of the things that make me feel dumb and that i wasted my time,
when I'm pk-ing players or (killing in other words) the player runs away as usually and heals, its a pretty common thing now in days... a but when you are pk-ing then they go in to a bike and heal and then run away it kind of makes you feel that you wasted your time chasing the player.

I really hate when they heal the way that you can't even touch them,
they run then use the jet pack and then heal while they are floating or flying w/e or they go in a bike and heal...

i would really like to fix that because more people are starting to do that.
i don't know if its a glitch or it is allowed but it really makes me and probably most players who have experienced that problem..
