Electric bicycles on the course.

[Ferrins]

Saw this for for the first time at Nudgee GC being used for a comp round.
I remember a number of years ago that our old trundles with the narrow wheels had to be replaced with wider ones to spread the load and protect the course. So rider, bike frame and motor weight plus bag and clubs would make the load around 10 times that of the old banned trundle with the similar tyres. So WTF?
