How do you adjust speed?

The speed control feature lets you precisely manage how fast your LEGO motors run. This is useful for:

- 🚂 Trains — simulate realistic acceleration and deceleration
- 🚗 Vehicles — control driving speed for cars, trucks, or cranes
- ⚙️ Mechanisms — fine-tune conveyor belts, cranes, or rotating parts
- 🔒 Lock speed — set a fixed speed so motors run consistently without holding the control

Adjusting Speed:
- Use the dial controls (A/B and C/D) on the app screen to increase or decrease motor speed
- The speed is shown in r/min on the display
- You can control up to 4 channels (A, B, C, D) — each corresponds to a port on the battery box

- If no need for remote control, for example 4217911389, adjust multiple speeds through touch switches, such as high, medium, and low speeds

Locking Speed:
- Tap the 🔒 lock icon at the bottom center of the app screen to lock the current speed
- This keeps the motor running at a fixed speed without holding the dial

💡 Tip: With up to 4 independent channels (A, B, C, D), you can control multiple motors simultaneously at different speeds.

Great that you're looking to motorize your LEGO Technic build! While other LEGO motors may physically fit, we do not recommend using third-party or standard LEGO motors with our system.

Our kits use specially designed motorized motors that are calibrated to deliver the exact speed and torque needed for smooth, reliable performance. Other motors simply can't match the speed and power output of our motors, which could result in:

- ⚡ Underpowered or sluggish movement
- ⚙️ Mismatched gear ratios affecting performance
- 🔧 Potential compatibility issues with our drivetrain components

For the best experience, we recommend using ZENE Bricks motor kits, which are purpose-built and tested for our LEGO Technic sets.

LEGO Technic is an advanced LEGO system designed to build functional, mechanical models that mimic real-world engineering. LEGO Technic is essentially a hands-on introduction to real mechanical and engineering principles! Here's how it works:

Core Building Elements:
- Beams & Pins — replace traditional LEGO bricks; connect parts at precise angles
- Axles — transfer rotational power through the model
- Gears — change speed, torque, and direction of movement
- Connectors & Bushings — hold axles in place and reduce friction

Mechanical Functions:
- Gear systems — combine different gear sizes to increase speed or torque
- Differentials — allow wheels to spin at different speeds when cornering
- Suspension — absorbs shocks for realistic vehicle movement
- Steering — rack and pinion or Ackermann steering systems

Motorization:
- Add motors, servos, and battery boxes to bring models to life
- Can be controlled via remote, Bluetooth app, or IR receiver
- Advanced builders use planetary gear reductions for more torque
