Hammer Speed Race X at a glance

• Heavy 20 kg flywheel: delivers an even, round pedal stroke that feels like real cycling, even at a high cadence.
• Magnetic resistance: a permanent magnet brakes without contact, so it stays quiet, maintenance-free and consistent for years.
• Quiet belt drive: the grooved belt runs smoothly and needs barely any maintenance, which is kind on your home and your neighbours.
• App connectivity: pair via Bluetooth with Zwift, Kinomap, Garmin and Hammer Workouts for virtual rides and structured training.
• Multi-Grip handlebar: three hand positions (Racing, Endurance, Comfort) let you switch posture on longer rides.
• Fully adjustable: set the saddle and handlebar for height and reach, so you sit efficiently and comfortably.

Flywheel and resistance

The heart of the Speed Race X is its 20 kg flywheel. That mass builds momentum and gives you a smooth, stable pedal stroke with no dead spots, exactly the feel that indoor cycling bikes are known for. The resistance comes from a permanent magnet that brakes without contact: computer-controlled and dependent on your cadence, so you can go harder or easier with precision. Because nothing rubs against the flywheel, the system is quiet, hard-wearing and maintenance-free. The grooved belt drive rounds it all off with a smooth, virtually silent transmission.

Display, tracking and apps

The LED/LCD display with SmartTurn technology and an integrated LED ring keeps track of your key training data, including your cadence and, via the thumb sensor, your heart rate. If you want more, pair the bike via Bluetooth with popular apps such as Zwift, Kinomap, Garmin and Hammer Workouts. That way you ride virtual routes, follow structured workouts and track your progress on your own tablet or phone. It makes every session more varied and helps you stay motivated.

Fit, posture and ease of use

A good posture makes all the difference on longer rides. The saddle and handlebar are both adjustable for height and reach, so the bike fits your body and you transfer your power efficiently. The Multi-Grip handlebar offers three hand positions, Racing, Endurance and Comfort, so you can switch posture as you ride. The clipless pedals give direct power transfer, and the central stop button brings the heavy flywheel to a quick standstill. Thanks to the transport wheels, you can tilt and move the bike despite its weight.

Who it is for and the space you need

This indoor bike is designed for home use, from the beginner who wants to train regularly to the ambitious rider putting in serious intervals. Measuring 110 x 55 x 120 cm, it fits most spaces, and with a weight of 45 kg it stands firm and stable on the floor. The maximum user weight is 130 kg. The steel frame is tested to the home-use standard (DIN EN ISO 20957, class HC).

Good to know

The Speed Race X comes with clipless pedals, so for the best power transfer you ride with matching clipless shoes. If you would rather train in ordinary trainers, keep that in mind. The bike is designed and tested for home use, not for intensive commercial use in a gym. For anyone who wants to do serious, varied indoor cycling at home, with a heavy flywheel and app connectivity, it is a great match.

Frequently asked questions about the Hammer Speed Race X

Who is this Indoor Cycle suitable for?

The Speed Race X suits beginners who want to build fitness at home and advanced riders putting in focused intervals. Thanks to the infinitely adjustable magnetic resistance, you decide for yourself how hard you train. The heavy flywheel gives a realistic cycling feel for steady endurance rides and punchy sprints. The bike is intended for home use.

Does the bike work with Zwift and other apps?

Yes, the Speed Race X is Bluetooth-compatible and pairs with apps such as Zwift, Kinomap, Garmin and Hammer Workouts. That way you ride virtual routes and follow structured training sessions on your own tablet or phone. Meanwhile, the built-in display shows your cadence and heart rate. That combination keeps your training varied and measurable.

Is the magnetic brake quieter than a friction brake?

Yes. With magnetic resistance, a permanent magnet brakes without touching the flywheel, so there is no rubbing noise and no wear. That makes the bike noticeably quieter and virtually maintenance-free compared with a classic felt brake. Together with the grooved belt drive, this is a great choice for use in the home.

Do I need special shoes?

The bike is fitted with clipless pedals, which give the best and most direct power transfer with matching clipless shoes. If you want to ride in ordinary trainers, keep that in mind when choosing. Clipless shoes help you pedal in rounder, more efficient circles, especially at higher intensity.

How much space do I need and can I move the bike?

The dimensions are 110 x 55 x 120 cm, so the bike fits in most living or training spaces. Also leave some room to move around it. At 45 kg the bike stands stable, and thanks to the transport wheels you can still tilt and roll it aside easily. A flat, solid surface works best.
