Turn your road bike, gravel bike, or MTB into a high-precision indoor training setup with a bike roller trainer. While rain, darkness, or cold keep you off the road, you can stay consistent with structured workouts, maintain your fitness, or prepare for your next race. Modern direct drive trainers deliver power measurements with ±1% accuracy and simulate climbs of up to 25%. They also connect seamlessly to platforms like Zwift, TrainerRoad, or Rouvy. At BIKE24, you’ll find everything from classic bike rollers for technique training to affordable bike trainer stands and high-end smart trainers with WiFi connectivity and realistic road feel. That way, you get the most out of every session – no matter the weather or time of day.
The next season won’t wait for better weather – with a bike trainer, you keep your fitness on track while others take a break.
Bike rollers and trainers vary in design, resistance system, and precision. Classic bike rollers focus on balance and pedaling technique, while modern direct drive trainers deliver maximum accuracy and fully interactive training. Whether you’re looking for simple bike rollers or a connected smart trainer, the right choice depends on your performance goals, budget, and setup.
You ride your bike on three rollers, without being fixed in place – just like riding on the road. This simple setup challenges your balance and technique, helps you develop a smooth pedal stroke, and works with almost any bike. Lightweight and low-profile, it’s easy to store and set up. Resistance typically comes from your gear choice and cadence, with electronic control rarely included. Ideal for technique training, warm-ups before races, or as a mid-range indoor setup (from around €160).
With this setup, you clamp your rear wheel into the trainer, where a resistance unit presses against the tire. This design makes setup quick and easy, with no need to remove the wheel. Modern wheel-on trainers offer electronically controlled resistance via ANT+ and Bluetooth, with outputs of up to 1,500 watts and gradient simulation of up to 15%. They’re also more affordable (from around €120) and more compact than direct drive trainers. Because the resistance unit presses against the tire, both tire wear and noise are slightly higher. Wheel-on trainers are a great choice if you want simple, effective indoor training without a more complex setup.
For a more natural ride feel, you mount your bike directly onto the trainer without the rear wheel. Power is transferred through your chain to the trainer cassette and straight to the flywheel. This design delivers maximum accuracy (±1%), resistance of up to 2,500 watts, ultra-quiet operation (under 60 dB), and a highly realistic ride feel thanks to precise inertia simulation. Top models simulate gradients of up to 25%, include road feel for different surfaces, and offer WiFi connectivity. Direct drive trainers are the top choice for structured training, virtual racing, and app-controlled workouts.
Riders doing structured FTP intervals on a road bike have very different needs than someone training indoors occasionally in bad weather. From resistance output to measurement accuracy and app compatibility, the following factors will help you choose the right trainer.
Direct drive trainers deliver maximum precision and performance for structured training. Wheel-on trainers offer quick setup and a more affordable entry point. Bike rollers improve technique and balance and are ideal for warm-ups and mobility work.
Entry-level trainers deliver around 1,000 watts, mid-range models up to 1,500 watts, and high-end systems up to 2,500 watts. For sprints and high-intensity intervals, at least 1,500 watts is recommended.
Entry-level trainers measure within ±3%, while high-end models reach ±1%. For structured training with defined power zones, high accuracy is essential – especially if you’re not using a separate power meter.
Bluetooth Smart (BLE) connects your trainer directly to apps like Zwift or TrainerRoad on your smartphone, tablet, or computer. This lets you track performance data and automatically adjust resistance. ANT+ FE-C offers the same functionality but also allows parallel connections to bike computers and other sensors. High-end models may also include WiFi, which provides a more stable connection and lower latency – especially useful for virtual racing.
Start by checking your bike’s axle standard. Most trainers support quick-release (130/135 mm) and thru-axles in 12×142 mm (road/gravel) and 12×148 mm Boost (MTB). Adapters are often included. The freehub must match your cassette: Shimano/SRAM HG is usually pre-installed, while XD/XDR and Campagnolo are available separately. For wheel-on trainers, also check wheel size compatibility (26"–29"). With direct drive trainers, this isn’t an issue since the rear wheel is removed.
