Indoor cycle – speedbikes

Indoor bikes were developed by professional cyclists in the 70s, to allow them to continue to train at home in winter or in bad weather. The speedbikes available today have developed from this period and skilfully bring both home athletes and professionals up to speed. Indoor cycling is healthy and effective cardio training.

Why is indoor cycling healthy?

Regular pedalling is a quick way to achieve success. Indoor Cycling is the perfect sport for anyone who wants to improve their endurance and strengthen their leg muscles.

  • It improves your strength endurance
  • It is gentle on the joints
  • It tones your legs
  • It trains your circulatory system
  • It promotes fat burning

How do I train on a speedbike?

The best training results are achieved with moderate cardio training of approx. 45 minutes. This duration allows most of the energy to be used from fat, which effectively reduces fat deposits and improves your endurance.

For a short and intense cardio workout, pedal continuously with high resistance or add extreme intensity peaks into your training. The knob allows the load to be adjusted simply and quickly.

What features do indoor bikes have?

Indoor cycles come directly from cycling and simulate cycling on the road like no other home trainer can. A large and heavy flywheel ensures a smooth and precise run. Revolving pedals ensure you do not get prematurely tired during your workout, but expose yourself to a continuous training stimulus to steadily increase your fitness and stamina.

The most important features are:

  • High flywheel mass
  • Revolving pedals
  • Ergonomic, cycling-specific design
  • Flexible adjustment of seat, handlebars and pedals
  • Excellent simulation of cycling on the road

What should I look for when buying an indoor cycle?

  • Resistance and braking system
  • Drive
  • Flywheel mass
  • Seat, handlebar and pedals
  • Training computer and heart rate measurement
  • Safety

The resistance and braking system

Most speedbikes have a built-in felt jaw brake that regulates the resistance and the brake as standard. The tried-and-tested braking system can be easily adjusted with an adjusting knob. Resistance is generated by two sturdy felt jaws that press from above or from the side onto the flywheel. Even more professional are race bikes with magnetic brakes.

The drive

There are simpler entry-level models with chain drives and higher quality models with belt drives. The clear benefit of belt drives is virtually noiseless training. Belts require no maintenance and, in contrast to chain drives, must not be lubricated. The FINNLO by HAMMER CRS 2 speedbike and the FINNLO by HAMMER CRT speedbike are equipped with high-quality belt drives.

The flywheel mass

A bike trainer’s flywheel mass is one of its most important features. Indoor cycles are a great way to simulate cycling, as they incorporate large flywheel masses, providing a very quiet, joint-friendly ride, even when you pedal fast. When buying, you should make sure that the flywheel mass is at least 18 kg. HAMMER bikes such as the FINNLO CRS 2 speedbike and FINNLO CRT speedbike are equipped with a 25 kg flywheel mass and have an incredibly smooth rotation.

Seat, handlebar and pedals

Fully flexible adjustment options for the seat and the handlebar are important for indoor bikes. To be as comfortable on your bike at home as you are on the road, indoor cycles must be as easy to adjust as roadworthy bikes. The built-in seat and handlebar therefore usually allow adjustment for all conceivable body sizes and leg lengths, so that an ergonomically perfect training position can be set for each individual user. Anyone who is unsure or is particularly small or large, should try out their future indoor cycle in advance in the store. In addition to the included handlebar and seat and built-in pedals, proud indoor bike owners can also use their own bicycle components. The connections for the seat and pedals are the same on speedbikes and racer bikes as normal bicycles, so you can attach clipless pedals or your favourite seat whenever you like.

Particular attention should be paid to the handlebar cover. It is important that it is covered with a high-quality and perspiration-resistant foam, to ensure the hands do not slip even during longer training sessions. In addition, the handlebar should allow for different grip positions and be stable, to ensure you can train in a sporty "racing posture" as well as leisurely in an upright position.

The seat should be made of very high-quality material and designed for long rides. FINNLO by HAMMER only uses premium saddles from the Selle Royal label, which are known to provide the athlete with a smooth and sore-free seat even on longer rides.

The pedals should ensure a safe, stable stand. As you often lift up your buttocks and train at your limits, optimal power transmission must be ensured and of course, you don’t want to slip off.

Training computer and heart rate measurement

Classic indoor bikes usually focus on the essentials: athletes should get benefit from almost meditative training options and can increase their endurance with more or less constant resistance per session. All the important data for cyclists such as time, distance and speed can of course be read. Race bikes with eddy current brakes commonly offer additional training programs that can be controlled by your heart rate. The heart rate can be measured easily using a heart rate monitor or a chest strap, which are important accessories in cycling training. For example, during high-frequency training you might reach your limit and a glimpse at your heart rate will you tell you when it’s time to slow down. A wireless connection between the heart rate monitor or chest strap and the training computer is an added bonus.


As freewheeling is deliberately inhibited in indoor cycling, an emergency brake is an important safety factor. The emergency brake must be within easy reach and fast to operate. An emergency brake is helpful if the flywheel mass has to be brought to a standstill quickly or if you accidentally slip off the pedal.
