SportsReflector transforms your cycling performance by providing unparalleled AI-driven analysis directly from your iPhone. Imagine having a world-class coach meticulously observing every pedal stroke, every body movement, and every subtle shift in your posture. Our advanced computer vision tracks critical aspects of your technique, such as your knee angle at the top and bottom of the pedal stroke, hip flexion and extension, and the timing of your power application. We pinpoint common inefficiencies like knee wobble, excessive upper body sway, or an uneven power distribution between your legs. These seemingly minor flaws can lead to significant energy loss and increased injury risk over time. Your form score, ranging from 0 to 100, is a dynamic reflection of your biomechanical efficiency and adherence to optimal cycling form. It's not just a number; it's a comprehensive assessment derived from analyzing hundreds of data points against a vast database of elite cyclists. As you refine your technique, your score improves, indicating a more powerful and sustainable ride. For our Pro users, the insights deepen considerably. Unlock detailed symmetry analysis to identify imbalances between your left and right sides, receive a full biomechanical breakdown highlighting specific joint movements and muscle engagement, and get early injury risk flags based on compensatory movements. Our muscle activation maps visually illustrate which muscle groups are firing effectively and which might be underperforming. Furthermore, our augmented reality (AR) live training overlays real-time visual cues onto your screen, guiding you to adjust your posture, knee alignment, or cadence as you ride, making corrections intuitive and immediate. Dive into drills like the 'Smooth Spinner' to perfect your circular pedal stroke, the 'Power Builder' to maximize force output, or the 'Cadence King' to optimize your rhythm and efficiency. SportsReflector is your ultimate partner in achieving peak cycling performance.
For the most accurate analysis, film yourself from the side, ensuring your entire body and the bike are in the frame.
The biomechanics of cycling are complex, involving a synergistic interplay of major muscle groups and precise joint movements. The primary movers include the quadriceps and gluteal muscles for the downstroke, and the hamstrings and calf muscles for the upstroke, working in the sagittal plane for propulsion. Force vectors are generated through the pedals, with optimal efficiency achieved when these forces are applied smoothly and consistently throughout the 360-degree pedal cycle. Computer vision plays a pivotal role in analyzing these intricate movements. Using advanced pose estimation algorithms, SportsReflector accurately identifies and tracks key anatomical landmarks, such as the hip, knee, and ankle joints, across multiple frames per second. This high frame rate allows for precise measurement of joint angles, velocities, and accelerations, even during rapid movements. Research consistently demonstrates that proper cycling technique, characterized by stable knee tracking, minimal upper body movement, and a balanced power output, directly correlates with improved power transfer, reduced fatigue, and a lower incidence of overuse injuries. Studies have shown that even small deviations from optimal form can lead to significant energy expenditure over long distances. While a human coach offers invaluable personalized feedback, SportsReflector's AI provides an objective, data-driven analysis that surpasses the observational capabilities of the human eye. The AI can quantify subtle biomechanical inefficiencies that are often imperceptible to a coach, offering consistent, unbiased feedback and tracking progress with unparalleled precision, complementing rather than replacing the human coaching experience.
One of the most common mistakes I see cyclists make, especially when they're new to serious climbing, is trying to power through ascents in too big a gear. They mash the pedals, gritting their teeth, thinking more power equals faster climbing. What actually happens is they burn through their anaerobic reserves far too quickly, leading to a dramatic drop-off in performance and often, a complete bonk before the summit. It's a classic case of ego overriding efficiency, and it's a surefire way to make climbing feel like an absolute suffer-fest every single time.
Instead of fighting the hill, learn to dance with it. Focus on maintaining a higher cadence, even if it means dropping into a smaller gear than your pride might initially allow. Think about a smooth, circular pedal stroke, engaging your hamstrings and glutes through the entire rotation, not just pushing down. A great drill is to practice climbing with one gear higher than you think you need, forcing that higher cadence. You'll find you conserve energy, maintain a more consistent pace, and ultimately, climb faster and with less overall fatigue. Trust me, your legs (and your race results) will thank you.

Common questions about using SportsReflector for cycling analysis
Cycling efficiency is determined by bike fit and pedalling mechanics. Beginners who establish correct position and cadence from the start avoid the knee, back, and hip overuse injuries that affect riders who prioritise power over technique.
Correct cycling position: seat height adjusted so the knee has a slight bend (25–35 degrees) at the bottom of the pedal stroke, seat fore-aft position with the knee over the pedal axle at 3 o'clock, handlebar height slightly above or level with the seat for comfort, and a slight forward lean from the hips (not the waist). Shoulders should be relaxed, not hunched.
