So, you went and bought a mechanical dropper seatpost for your mountain bike, only to discover that smoother-moving, faster-acting electronic posts are now “a thing.” Well, don’t despair, as the OnlyMotion system is designed to make your existing dropper seatpost electric.
I’ve had pretty decent luck with battery powered flashlights for bikes, and LED runner vests for visibility on roads! They have a lot longer battery life than they did in the 00s.
Oh yeah, they work just fine, as long as you charge them anyways lol. I just like the idea of never worrying about a battery, ever.
