I wouldn't use tape either, I grew up using old tubes as bungees, so I'd have a piece of an old one cut and use it to tie a spare one to the bike. Very swappable between bike, non sticky, no need of bolts/holes, cheap and can make many from one single old tube. ;)
Edit: I obviously wouldn't ditch the old tube, that's just more bungees!
