Hammerhead Posted August 2, 2020 Share Posted August 2, 2020 Not much into extraneous gadgetry, but this affordable little addition seems to work well enough so far & takes the wonder element out of those critically inflated round rubber bits Simple valve cap sensors with coin batteries & a USB rechargeable monitor. Auto on off by the motion of the bike. Sure nice to know at a glance how well my sacks are doing ! Amazon find under 100 loonie$, recommend! 8 Link to comment Share on other sites More sharing options...
