Searching for anime...

Hello,

Somewhere during 1978 and 1995 a television serie was broadcast in The 
Netherlands.

Some kind of cartoon which had the following:

1. Robots.

2. Girls

3. Pink/Purple robots, ball-shapes.

4. Bikes.

I think but not sure girl with blue hair.

The series kinda looked like robotech but it's not robotech, not gundamn, 
etc.

Any idea ?

Bye,
  Skybuck.
