Love your dropper post but hate the slow, stiff activation?
Meet OnlyMotion, the first-ever electronic conversion kit that turns your dropper post into a high-tech, wireless system. No mechanical cable, no hassle : just an instant response.
Instant activation. Easy installation. Zero maintenance.
Upgrade your ride today, because every second on the trail counts!
Why Upgrade to Electronic?
✅ Lightning-fast response – press and it activates immediately
✅ No mechanical cables – A cleaner, sleeker setup with zero maintenance.
✅ Easy installation – works seamlessly with most bikes
✅ 150h ride time per charge – Up to 4,000 activations on a single charge.
✅ Fast USB-C charging – ready to ride in just 10 minutes
✅ IP65-rated protection – dustproof and water-resistant, built for tough riding conditions
A dropper post is one of the most game-changing components on a mountain bike, but traditional mechanical systems slow you down. Stiff levers force you to overextend your thumb, cause unnecessary resistance, and make split-second adjustments harder than they should be.
With OnlyMotion, activation is instant, smoother than a mechanical lever, and designed for better control and safer riding—so you can focus on the trail, not on your gear.
Less effort = better grip, more control, and safer riding.
🚴♂️ Upgrade your ride today! Experience the power of effortless activation and ride with confidence—back us on Kickstarter now!
Instant Response – No Delay, Just Action!
Wondering how fast our electronic dropper post conversion really is? This one-take, unedited demo proves it, press the button, and the actuator responds instantly. No lag, no hesitation,.
Easier Installation Than a Mechanical Dropper Post
Our ultra-thin (4.3mm) charge cable is designed to be smoother and more flexible than traditional mechanical cables. Thanks to its low-friction sleeve, internal frame routing is effortless, making installation quick and hassle-free, no special tools, no frustration.
Unlike mechanical setups, there’s no fine-tuning, no cable stretching, and zero maintenance, just install and ride.
✔ No tedious adjustments
✔ No maintenance—ever!
🎯 Upgrade to a seamless, frustration-free setup today!
Durable, Lightweight & Built to Last
We’ve designed a high-tech, ultra-lightweight system that is 125g (0.33lbs) lighter than the SRAM Reverb AXS (including battery, without remote).
Every gram has been optimized to give you the lightest, most efficient dropper post upgrade possible. In fact, our actuator is no heavier than a standard mechanical cable and lever setup—but infinitely more advanced.
Ready for Production – Built with Precision, Engineered for Performance
From concept to reality, OnlyMotion is ready to roll!
Our Canadian design team is made up of experienced engineers and manufacturing specialists dedicated to delivering the best product possible. Our new product, under the brand OnlyMotion, is assembled and tested in Canada to ensure top-tier quality and an efficient production process.
We are currently in the pre-production phase, and the first production run is just around the corner!
Actuator Battery Protection
One advantage of our design is that the actuator battery is securely housed beneath the dropper post, protecting it from impacts and maintaining a sleek, streamlined look. Additionally, its placement shields it from direct water jets when washing your bike.
Wireless remote
Our minimalist wireless remote is designed for compactness, ergonomics, and effortless control. The large paddle switch enhances responsiveness, allowing instant activation from multiple angles with minimal effort, ensuring seamless operation on any terrain.
Precision-machined from 7075 aluminum, the main housing offers maximum durability and impact resistance, guaranteeing reliability even in the toughest riding conditions.
An integrated LED indicator provides real-time feedback on battery life and connection status, keeping you informed at a glance.

150 Hours of Ride Time (Up to 4000 Activations!)
Ride longer, charge less, because downtime isn’t an option.
Never worry about battery life again! With up to 150 hours of ride time, you’ll rarely need to charge. And when you do, a quick 10-minute charge gives you a full day of riding. A full charge takes just over 2 hours, ensuring you’re always powered and ready to ride.
- Up to 4000 activations per charge
- USB-C fast charging – 10 minutes = a full day of riding
- Reliable, long-lasting performance
Ride more, charge less—pre-order now on Kickstarter!
Charge Process – Quick, Simple & Hassle-Free
Stay powered up with effortless charging—because every ride counts!
Charging your OnlyMotion system is as easy as plugging in your phone. With fast USB-C charging, you’ll be ready to hit the trails in no time. Both the remote and actuator charge simultaneously, so you’re always prepared for your next ride.
- Grab the actuator charge cable and plug it into your remote.
- Connect a USB-C cable to a power source such as a cell phone, power bank, car USB port, or wall adapter.
- Both the remote and actuator will charge simultaneously. A LED indicator will confirm when charging begins and when it’s complete.
- Once fully charged, disconnect the USB-C cable and store the actuator charge cable back in the frame.
The Actuator: Powerful Brushless Motor & Advanced Engineering
Precision, power, and innovation packed into a compact design.
Our patent-pending design features a custom high-power brushless motor, delivering the efficiency, speed, and power needed for the job. Fun fact: the actuator is strong enough to lift 200 times its own weight!
Our assembly may be lightweight, but it is crafted entirely from high-quality metals, ensuring exceptional durability, rigidity, and longevity. Built to withstand the toughest conditions, it combines strength with precision engineering for a rock-solid, maintenance-free experience.
To fit everything into such a compact space, we utilized every bit of available space without adding length to the stack and we made it work. Our flexible PCB arrangement allows us to wrap electronics around the battery, maximizing space efficiency while also simplifying assembly.
Testing, testing and more testing !
We have rigorously tested multiple units for months under extreme temperatures, both hotter and colder than typical riding conditions, using our climate chamber, and they’ve withstood every challenge. Fat bike riders, rest assured—we’ve got you covered!
While lab tests provide quick and controlled results, nothing compares to real trail riding. That’s why nearly a dozen of our prototypes are currently being pushed to their limits on the trails, enduring harsh conditions to ensure reliability in the toughest environments.
Tested. Proven. Trail-ready. Back us now on Kickstarter!
Will it fit my bike ?
Unlike stiff mechanical cables, our charging cable is flexible and designed to minimize insertion depth loss. The actuator diameter is 30.7mm, making it compatible with down tubes starting at 30.9mm.
📏 How to Calculate Dropper Post Fitment
1. Visit OneUpComponents.com
2. Follow their standard procedure.
3. Adjust your insertion length as follows. Instead of removing 10–20mm as recommended by OneUp, remove:
- Frame Type A: Subtract 28mm
- Frame Type B: Subtract 35mm
- Frame Type C: Subtract 10mm
- Frame Type D: No adjustment needed (0mm)
- Other types of frame: If your frame isn’t listed, use the worst-case scenario measurement and subtract 38mm from your available space.
For the most accurate fit, we recommend using our 3D print test file to ensure compatibility before purchasing.
Type A : Dridge inside the downtube for shock or other
Type B: Bended seat tube
Type C: Straight seat tube
Type D : Cable exits the seat tube and routes into or along the downtube
