Bike electronics

From GPS bike computers and bike lights to heart rate monitors, action cams, and e-bike components, today's cycling electronics help you ride farther, train smarter, and stay connected. Whether you're upgrading your road bike, mountain bike, gravel bike, or e-bike, you'll find the latest bike electronics from leading brands at BIKE24.

Electronics have transformed cycling. From bike lights and GPS navigation to electronic shifting and integrated e-bike systems, smart technology is now part of almost every ride.

It wasn't always that way. When Karl Freiherr von Drais invented the bicycle more than 200 years ago, it was a purely mechanical machine. Electric bike lights first appeared in the early 20th century, gradually replacing earlier chemical lighting systems. As battery technology advanced, bike electronics became more practical, reliable, and widely available.

Bike lights were only the beginning. Advances in microelectronics during the 1980s introduced the first digital bike computers, replacing mechanical speedometers with compact displays that tracked speed, distance, and ride data. Today, bike computers, GPS navigation devices, and integrated displays are standard equipment for many cyclists and e-bike riders alike.

The biggest advances in cycling electronics have come over the past 15 years. The rapid growth of e-bikes has accelerated innovation across the entire industry. Today, it's not just motors and batteries that make an e-bike smart – electronic technology is integrated into everything from displays and lighting to connectivity and performance tracking. Discover the latest components in our e-bike parts section.

Beyond e-bikes, bike electronics now cover almost every aspect of riding. Bike lights and bike computers have become everyday essentials, while heart rate monitors and sports watches help athletes train more effectively. GPS navigation devices make route planning and exploring new roads easier, muscle stimulation devices support recovery after tough rides, and action cams let you capture every adventure. Here's an overview of the key categories in modern cycling electronics.

Whether you're upgrading your bike, tracking your performance, navigating new routes, or speeding up recovery, modern cycling electronics make every ride safer, smarter, and more enjoyable. From bike lights and GPS computers to heart rate monitors, action cams, and e-bike components, here's an overview of the key categories and the technology behind them.

Bike lights have come a long way since the candle and oil-powered lamps of the late 19th century. Today's lighting systems offer reliable visibility, powerful illumination, and smart features for every type of bike. You'll find everything from battery-powered and rechargeable bike lights to dynamo systems and fully integrated e-bike lighting powered directly by the bike's battery. Premium e-bike lights can even include features such as daytime running lights, high beams, and brake lights for added visibility and safety.

Complete your setup with the right accessories, including mounts, cables, and replacement parts to keep your lighting system ready for every ride.

Whether you're training for your next race, exploring new routes, or heading out on a bikepacking adventure, bike computers and GPS navigation devices help you get more out of every ride. They track key ride data such as speed, distance, elevation, and performance metrics, while clear displays keep everything at a glance. What started as a training tool for ambitious road cyclists has become an everyday companion for riders of all disciplines. Modern GPS bike computers combine detailed ride tracking with reliable navigation, making it easy to follow routes and discover new roads and trails with confidence. Explore our full range of bike computers and GPS navigation devices to find the right setup for your next ride.

Whether you're training on the bike, running, or staying active every day, heart rate monitors and sports watches help you track your performance and monitor your health. Many modern bike computers support heart rate monitoring, but sports watches offer a versatile alternative that seamlessly transitions from training to everyday wear. Today's sports watches combine advanced fitness tracking with sleek, everyday designs, making it easy to keep an eye on your health and performance wherever you go. Complete your setup with the right accessories, including mounts, replacement watch straps, digital maps, heart rate straps, cadence sensors, and more for your bike computer or sports watch.

Muscle stimulation devices use electrical muscle stimulation (EMS) technology to support training and recovery. By sending controlled electrical impulses to your muscles through electrodes, they can help activate specific muscle groups before a workout or aid recovery after long rides and intense training sessions. Compact and easy to use, EMS devices are ideal for cyclists who train regularly or spend a lot of time traveling. Their portable design makes it easy to take your recovery routine wherever your next ride takes you.

Capture every climb, descent, and unforgettable view with a camera or action cam. Technical mountain bike trails, tackling epic road routes, or bikepacking adventures, these compact cameras let you relive and share your best moments. Built to withstand the demands of cycling, modern action cams are lightweight, rugged, and easy to mount. Choose from a range of mounting options to find the perfect camera angle – whether it's on your handlebar, helmet, frame, or chest harness. Browse our selection of cameras, action cams, and mounts to find the right setup for your next adventure.

Smartphones and tablets have become valuable tools for navigation, training, ride analysis, and staying connected on the go. With the right accessories, you can integrate your devices seamlessly into every ride. Our range includes handlebar mounts for secure access on the bike, as well as protective cases that help shield your devices from rain, cold, and everyday wear. If you train with your smartphone, you'll also find compatible Bluetooth heart rate monitors that pair with popular training apps to track your performance in real time.

Many bike electronics rely on a dependable power supply. Bike computers, GPS navigation devices, lights, and other accessories often use rechargeable batteries that can be charged via USB, while some lights still run on replaceable batteries. Our range includes everything you need to keep your devices powered, from batteries, chargers, and cables to portable charging solutions. Heading out on a bikepacking trip or multi-day tour? Compact solar panels let you recharge compatible devices on the go, while portable power stations provide even more flexibility for camping and extended adventures.

Choosing the right cycling electronics starts with compatibility. Whether you're buying a bike light, GPS bike computer, smartphone mount, or charger, make sure it's compatible with your bike, your existing components, and any devices you want to connect. This is especially important for accessories. Smartphone mounts need to fit both your handlebar and your phone, while lights, displays, sensors, and chargers often need to match specific systems or mounting standards. To help you choose with confidence, we include detailed compatibility information in our product descriptions, making it easier to find the right electronics for your setup.

Whether you're training, commuting, touring, or chasing your next adventure, the right bike electronics can make every ride safer, smarter, and more enjoyable. From bike lights and GPS bike computers to sports watches, action cams, smartphone accessories, and e-bike components, BIKE24 offers a wide selection of products from leading brands for every type of rider.
