How to choose a bike speed sensor

Selecting the right bike speed sensor depends on how you ride and what data you need. The primary function is to measure wheel rotations to calculate speed and distance, which is more reliable than GPS in certain conditions. For a deep dive into cycling tech, visit our bike computers category.

What to look for

  • Connectivity: Most sensors use ANT+ and/or Bluetooth. ANT+ is common for connecting to multiple devices like bike computers and trainers simultaneously, while Bluetooth is key for smartphone apps. Check compatibility with your existing gear.
  • Mounting & Design: Hub-mounted sensors are widely used for a clean, magnet-free look. Ensure the sensor fits your wheel hub and comes with the necessary mounts. For cadence tracking, you’ll need a sensor that mounts on the crank arm.
  • Durability: If you ride in all conditions, look for a listed IP67 waterproof rating, which means the sensor is protected from dust and immersion in water. This is crucial for cycling equipment meant to handle the elements.
  • Function: Decide if you need just speed data or both speed and cadence. A 2-in-1 sensor can be more versatile, but a dedicated speed sensor might be simpler. For indoor training, verify app compatibility like Zwift or Rouvy.

Always follow the manufacturer’s manual for installation and pairing. Proper sensor placement is critical for accurate data. For more on essential cycling gear, see our guide on the best bike water bottles.

FAQ

How does a bike speed sensor work?

A bike speed sensor typically attaches to your wheel hub or a spoke. It detects each rotation of the wheel. By knowing your wheel’s circumference (which you often input during setup), it calculates speed and distance based on the rotation rate, providing data without relying on GPS signal.

What’s the difference between ANT+ and Bluetooth?

ANT+ and Bluetooth are both wireless protocols for transmitting data. ANT+ is known for low power consumption and the ability to broadcast data to multiple receiving devices (like a bike computer and a trainer) at once. Bluetooth is universally used for connecting to smartphones and tablets. Many modern sensors support both for maximum compatibility.

Do I need a speed sensor if my bike computer or watch has GPS?

A speed sensor provides valuable backup and increased accuracy. GPS signals can drop in urban areas, under tree cover, or indoors on a trainer. A speed sensor fills these gaps, providing consistent speed and distance data. It’s also essential for tracking distance on a stationary bike where GPS is ineffective.

Can I use one sensor for both speed and cadence?

Some sensors are marketed as 2-in-1 units. However, it’s important to read the listing details. Some are a single device that must be switched between speed or cadence mode, meaning it can only track one metric at a time. Others are a combined package with two separate sensors or a single unit that tracks both metrics simultaneously.
