Real Design Tech Co., Ltd. designs and manufactures Ultiracer - a screen-based indoor cycling platform that pairs responsive mechanical hardware with a connected software stack to deliver whole-body, cognitively engaging exercise for healthy aging, early screening, rehabilitation, and athletic training.
What is Ultiracer
Ultiracer is a free-moving indoor cycling training rig.
Riders can lean, steer, move left and right, and must self-stabilize through full-body coordination in a state of constant stimulus.
The Ultiracer kiosk and RDT Cloud system collects real-time sensor data (speed, position, heart rate, cadence, power, IMU, etc) into a centralized platform for reporting and analysis.
IP Portfolio: Recognised as a Top-10 Leading Company by IP in Screen Sports. 32 issued patents covering the four-axis motion mechanism.

EMG channels show broader, higher muscle activation on Ultiracer vs a fixed cycling roller.
Platform & App - AI-Ready by Design
Data & User Pipeline
- Sensor ingestion over USB and BLE from kiosks/pc/app.
- TimescaleDB hypertables for speed, position, heart rate, cadence, power, and IMU
- Privacy-first: GDPR and Korean PIPA compliant
- Per-user longitudinal history and session logs, suitable for downstream ML and population analytics
Built-In Test Protocols
Literature-backed cognitive-motor tasks delivered during and after a ride:
- Stroop-style colour-word interference task
- Dual-task reaction drills during sustained cadence
- Perfect Racer - distance-precision mode with tiered scoring
Full-body coordination tasks unique to Ultiracer
