- FEATURES -

IAV CYCLING DYNAMICS
Our power meter pedals provide advanced metrics called IAV (Instantaneous Angular Velocity) Cycling Dynamics: IAV Power Phase and IAV Rider Position. These metrics, combined with the classic power data, permit you to analyze your pedaling technique in detail and learn about how your position on the bike influences your performance.

IAV POWER AND GYROSCOPE
Assioma takes into account irregular pedaling (e.g. uphill, sprints) or the use of oval chainrings. Assioma can detect the actual instantaneous angular velocity during the whole pedal stroke, thus providing ±1% accuracy in any conditions.

 

BLUETOOTH AND ANT+
Assioma UNO pedals feature both Bluetooth and ANT+ connectivity for a seamless compatibility with bike computers and smartphones (both Android and iOS).

 

PEACE OF MIND
Favero offer 2-Year replacement warranty against defect.

 

EASY TO INSTALL. FAST TO MOVE BETWEEN BIKES.
Install and move your Assioma power meter from one bike to another just like a normal pedal, easily and without special tools.

 

MAKE THE MOST OF EVERY PEDAL STROKE.
To provide you with unprecedented detailed and precise data, the Assioma power sensors are placed on the pedals, exactly where your force goes. Pair it with your smartphone or bike computer instantly, using Bluetooth and ANT+ communication.

 

AUTOMATIC TEMPERATURE COMPENSATION
You can count on the most accurate and consistent real-time power data thanks to proprietary technologies, innovative software solutions and the advanced electronics of Assioma. Ride without fear in the snow, rain, mud, or sweltering heat: the automatic temperature compensation (ATC) ensures exact and reliable watt measurements in any weather conditions at temperatures between -10°C and 60°C.

 

WATERPROOF, RESISTANT ... AND THE LIGHTEST EVER MADE
The lightest and most compact pedal-based power meter: with no protruding elements, it does not interfere with the pedalling. Not even when cornering. Protected by a bi-component resin block, the power meter sensor is extremely resistant to shocks and fully waterproof.

 

USB RECHARGEABLE - WITH AUTOMATIC STANDBY
The lithium-ion technology provides a long battery life: up to 50 hrs with a single charge. You can recharge your cycling power meters simultaneously thanks to the battery charger with double USB cable and magnetic connectors.

After a few minutes of inactivity, Assioma automatically sets to stand-by and instantly switches on as soon as you start pedaling.

 

ASSIOMA APP - MANAGE WITH CONFIDENCE
With the Assioma App you can monitor the battery charge level, set crank-arm length, wirelessly update firmware, and keep up to date on new data analysis functions.

 

- MEASURED DATA -

  • Power - measures the power hundreds of times per second and continuously transmit the collected data to your bike computer or smartphone via Bluetooth and ANT + technology.
  • Cadence - indicates the number of revolutions made by the pedal in one minute (rpm). The in-built cadence sensor of Assioma constantly detects and transmits this value to the bike computer: making it therefore superfluous to use a separate cadence sensor.
  • Left/Right Balance (DUO only) - indicates, as a percentage, the power individually generated by the left leg and the right leg. The L/R Power Balance values allow you to monitor the dominant/non-dominant leg ratio and observe how this varies in relation to different racing and fitness conditions. This can be useful to correct penalizing imbalances: also in post-traumatic rehabilitation programs. Unlike others, the Assioma power meter pedals return these metrics through real dual-sided measurements, not estimates
  • Torque Efficiency (TE) - indicates, as a percentage, how much of the power generated during one pedal stroke actually contributed to the propulsion of the cyclist. A 100% Torque Effectiveness occurs when no Negative Power has been accumulated during a pedal stroke. The typical TE value may vary between 60% and 100%. Assioma UNO indicates the Torque Effectiveness value for the left leg; whereas Assioma DUO provides data for both left and right leg.
  • Pedal smoothness (PS) - indicates, as a percentage, how evenly distributed the power is in a full revolution of a pedal stroke. A value of 100% means that the power is delivered constantly throughout all the revolution: the higher the value the "rounder" the pedaling. Assioma UNO indicates the PS value of the left leg; whereas Assioma DUO provides separate data for both the left and the right leg.

Durable But Quirky Interactive Ball
Color: Blue
I am 30 now and my tolerance for toys that break in 2 minutes is basically zero. I picked this up during a weekend DIY project when I was fixing the deck and needed something to keep the dog occupied. The E TPU material is straight up impressiveuch abuse it can take from a large breed. My dog tends to destroy generic store brand balls but this one survived being dropped down the stairs and tossed against the siding. It is comfortable enough to use daily without feeling like it is going to shatter or hurt the dog. The internal compartment where you charge it is smart and those little pockets for the charging port are actually useful sized for my fat fingers. The smart movement is a game changer for keeping a high energy dog moving when I am busy with home improvement tasks. I was slightly worried about the 8 hour battery life but it holds a charge well enough for a few play sessions. My whole household uses this now to entertain the dog as he will not leave us alone otherwise. It works best on my kitchen tiles but it barely moves on the thick rug in the living room which is frustrating. The vibration is loud enough to be annoying when I am trying to focus on work. It is a solid 3 star product as it does what it says but has some quirks that make it less than perfect. Spending 19.99 is fair for the durability you get compared to cheaper options. I like that it is USB rechargeable instead of eating through batteries. It is not perfect but it serves a purpose in my chaotic house.

Engaging and Durable: High-Energy Play with a Caveat for Sensitive Pups
Color: Blue, Color: Blue
Finding an automated toy that can survive the jaws of an aggressive chewer while keeping them physically engaged is a major win for busy pet owners. This smart interactive dog toy offers an excellent, high-tech way to keep high-energy dogs active, though its enthusiastic movement might be a bit intense for more timid pets. Dynamic and Instinct-Triggering Movement: The core appeal of this toy is its smart interactive movement. This automatic bouncing ball activates immediately upon touch, rolling and bouncing in entirely unpredictable directions. This erratic motion successfully triggers a dog's natural chasing instincts, keeping them thoroughly engaged and entertained for hours, which is incredibly helpful when you are unavailable to play. However, because the movement is so sudden and dynamic, it can occasionally scare more sensitive or easily startled dogs. Chew-Proof and Safe Construction: The durability and structural safety of the ball are highly impressive: *Chew-Proof E-TPU: Crafted with a high-density E-TPU shell, the toy is specifically built to withstand aggressive chewing and rough play from medium to large breeds. It holds up remarkably well against scratches and deep bites for long-lasting use. *Pet-Friendly Materials: The non-toxic, BPA-free material is completely safe and remains gentle on your dog's teeth and gums during fetch or heavy chewing sessions. *Injure-Free Design: The toy is engineered with smooth, rounded edges to prevent any accidental cuts or injuries during high-speed play. Supporting an Active Lifestyle: This toy serves as a fantastic tool for supporting an active lifestyle. It encourages vital daily exercise to help maintain your dog's physical health, significantly reduces boredom, and curbs destructive behaviors like furniture chewing. This makes it an absolute lifesaver for high-energy pups that need a constant physical outlet. Convenient USB Rechargeability: Powering the toy is simple and environmentally friendly. It is equipped with a USB rechargeable battery that delivers up to 8 hours of continuous play on a single charge. It also includes the necessary USB charging cable, ensuring you can quickly plug it in and have it ready for the next play session without constantly buying disposable batteries. Bottom Line: I highly recommend this smart interactive dog toy for owners of high-energy, medium-to-large breeds that need an indestructible, engaging outlet. While it may frighten more timid or anxious dogs due to its unpredictable bouncing, its premium E-TPU durability, great battery life, and excellent exercise value make it a fantastic investment for a healthier, happier pet.
