Main Differences (Unique Points)

1) Maximum Speed / Power

• Z3 Hybrid Plus: up to 6.2 mph (10 km/h)
• R3 Hybrid Plus: up to 7.5 mph (12 km/h)
• Implication: If speed matters, the R3 is faster.

2) Max User Weight Capacity

• Z3 Hybrid Plus: 110 kg (242 lb)
• R3 Hybrid Plus: 120 kg (265 lb)
• Implication: R3 offers more headroom for heavier users.

3) Walking/Rolling Surface Size

• R3 Hybrid Plus: 120 cm long x 44 cm wide (also stated as 47.2 in x 17.3 in)
• Z3 Hybrid Plus: 120 cm long x 40 cm wide (also stated as 47.2 in x 15.7 in)
• Implication: R3 has a slightly wider deck.

4) Automatic “Foot Sense” Speed Mode (Walking-Pad Mode Only)

• R3 Hybrid Plus: Includes foot sense automatic speed control:
  • Step forward → speed increases
  • Stay in the middle → speed stays the same
  • Step back → speed decreases
  • Step out of the machine → stops automatically
• Z3 Hybrid Plus: No foot-sense feature.

5) Safety Key Storage Box Issue (R3-Specific Drawback Mentioned)

• Both models have:
  • A storage box for the remote/phone
  • A security key that should be plugged in
• Downside (not ideal): In walking-pad mode, the storage box is slightly too small for the safety attachment, so it may rest on the ground.
• Suggested improvement: Increase storage box size by a few centimeters.

6) Display Aesthetics / Ergonomics

• Z3: Inclined display for easier reading (speed, distance, steps, calories)
• R3: Red lighting for a more “fun/model” look

7) Frame Styling

• R3: more rounded look
• Z3: more square look

8) Noise / Motor

• Both use a 735W brushless motor:
  • described as powerful but not too noisy
• Noise/vibration mitigation is also supported by adjustable feet.
