When I want people to know I'm coming I shout at them, then they have two choices move or get hit. Old people or young also handicapped or odd looking I let off!
As for best sounding hubs. Single track is bad for going on about looking at bikes and people showing off their rides.
But now we have reached a whole new level of genius, listening to bikes, why not record the sounds and download them into a yamaha or similar keyboard. Then you can listen to what ever sound you like and with a beat of your choice.
OOH sweet music to my lugs!!!
How many of you have listened to your hubs tonight???
