Why Training with a 4iiii Power Meter Is a Game Changer for Everyday Cyclists

If you’re serious about improving your cycling—whether that’s getting faster on your commute, building fitness, or pushing further on weekend rides—there’s one upgrade that can make a real difference: a 4iiii power meter.

At Merlin Cycles, we believe in making high-performance cycling tech accessible to all riders. Power meters aren’t just for pros anymore—they’re for any cyclist who wants to train smarter, track real progress, and get more out of every pedal stroke.


Train Smarter, Not Harder

Speed and heart rate only tell part of the story. Power—measured in watts—is the most accurate indicator of your cycling effort. It’s unaffected by temperature, fatigue, or terrain, giving you a consistent measurement of how hard you’re working.

With a 4iiii power meter from Merlin Cycles, you can:

  • Train within precise power zones tailored to your goals
  • Improve your pacing on climbs, intervals or time trials
  • Avoid burnout by managing your workload scientifically and accurately

When you train with power, you stop guessing and start improving.


Precision You Can Depend On

4iiii’s patented 3D strain gauge technology delivers accuracy within ±1%, giving you confidence that your data reflects your true effort. Every watt counts, and 4iiii ensures you capture them all.

That precision means you can:

  • Benchmark your performance accurately
  • See steady progress over weeks and months
  • Fine-tune your training with hard data – not guesswork

It’s pro-level insight, made simple for everyday riders!


Lightweight, Durable & Ready to Ride

For cyclists who ride year-round, reliability matters. 4iiii power meters are:

  • Ultra-light, adding only a few grams to your crank arm
  • Weather-sealed, perfect for unpredictable UK rides
  • ANT+ & Bluetooth compatible, working seamlessly with Garmin, Wahoo and popular training apps

Setup is quick and hassle-free—fit, pair, and ride. No complicated installs or tools needed.
