No problem carting your mal around Bali,done it for years.
All taxis at the airport will carry your stick on the roof.
They remove the sign and strap it on. Also most drivers
carry straps.I have seen longboards on scooters but my
9.4 is a little difficult to zap around.
Have a great trip

PS.straps as in rope,so you may want to BYO.
