Wireless dropper posts are one of the most effective upgrades you can make to your mountain bike, with effortless actuation and little required maintenance making them easy to live with.
The only problem is the price, with even the cheapest models costing £400 / $500.
OnlyMotion has set out to fix this with its wireless electronic conversion kit.
The brand says the device enables you to upgrade your existing dropper post, providing instant, effortless control.
OnlyMotion is currently seeking backing on Kickstarter for the wireless actuator, with early-bird buyers able to secure the device for $174.
Wireless upgrade
OnlyMotion says the patent-pending actuator integrates directly into the seat tube, shielding it from dirt and water, ensuring long-term reliability in all conditions.
It is also IPX7-rated, meaning it should be able to deal with wet winter trails.
The system works using a brushless motor that actuates the dropper post in the seat tube. This is then connected to a remote on the handlebar.
OnlyMotion says the system is wireless, but in some teaser trailers, the actuator and remote appear to be connected via wire, while in others they look to use a wireless network.
The wireless remote itself is ring-shaped and made from 7075 aluminum, featuring a large paddle that should help with easy activation.
An LED indicator on the remote shows battery information, as well as connectivity status.
The brand says the device is currently compatible with the Fox Transfer, Bontrager Line, Race Face Turbine R and OneUp V2 & V3 posts, with more to follow in the near future.
While the brand says the device is compatible with a host of dropper posts, that's not to say it will work with your setup, because the extra length added to the post may cause insertion issues depending on your frame.
The device charges via USB-C and is said to last for 150 hours of riding per charge, which OnlyMotion equates to 4,000 actuations.
OnlyMotion says charging is fast, with 10 minutes giving the system enough juice for a day's riding.
