With a new battery but decreased range, the most likely culprit is lowered motor efficiency.

When powered on, motor heat builds up. At high temps, chemical reactions occur between water and permanent magnets, causing demagnetization and reduced motor efficiency.

Keeping the motor cool is key. Here are some tips:

1. Maintain good riding habits, avoid high speeds that overheat motors.
2. Don’t modify the electric tricycle or meddle with speed controls, as high currents also cause overheating.
3. Park indoors or under shades when not in use to prevent sun and rain exposure. Also avoid riding through water.
4. Regularly inspect motors for cracks and rust on axles. Fix promptly if found.
5. Don’t buy cheap or refurbished products when purchasing an electric tricycle.

Controlling motor temperature preserves efficiency and range. Proper use and maintenance safeguards your investment. Let us know if you have any other electric tricycle care questions!
