Question

What are the basic rules of the kieren bike race? why a scooter at the front first few laps?

Answer 1

It is spelt Keirin (you can search it better that way)

It is Pretty simple really

The scooter sets the pace (none allowed past), slowly increasing speed, it pulls off when it gets to a set speed. (usually around 50 km/h)  The riders then sprint home; first one over the line wins.

Pace can be set by anything, another rider a tandem or a motor bike. They use an belt driven electric scooter in mostly as the chances of dropping oil are greatly reduced.

Here is a link. But do a few searches yourself now that you know how to spell it.
