2. Region-Specific Legal Upgrade Rules (US / EU / UK)

2.1 EU & UK Strict Rules

EU and UK laws strictly limit power and speed parameters: max 250W motor power and 25km/h assisted speed. Any modification that breaks factory parameter limits is illegal. Only pure external non-electrical upgrades are permitted.

2.2 US Flexible Rules

US federal regulations allow 750W max power and 32km/h standard speed. URLIFE US-spec models reserve reasonable upgrade space. Users can replace matched tires and shock-absorbing parts appropriately, but cannot unlock speed limit excessively.

2.3 E5 Dual Version Special Note

For the new URLIFE E5 dual versions: US e-bike version and EU/UK e-moped version have different factory parameter locks. All legal external upgrades are universal, while internal electrical modification standards follow local regional laws.

3. High-Risk Forbidden Modifications (Must Avoid)

These behaviors are the main causes of fine, vehicle seizure and warranty voidance, strictly prohibited for all URLIFE users:

3.1 Illegal Electrical Parameter Tuning

  • Dismantle factory speed limiters to unlock over-speed riding
  • Modify controller and program to increase motor power output
  • Replace high-voltage and high-capacity non-original batteries
Risk: Invalidates warranty completely; EU/UK imposes heavy fines up to thousands of euros; over-speed riding leads to full traffic responsibility in accidents.

3.2 Structural & Spec Overhaul Modification

  • Change original tire size, wheel hub and brake system at will
  • Remove original pedal assembly and safety warning devices illegally
  • Modify frame structure and shock absorption components privately
Risk: Damages vehicle balance performance, causes potential safety hazards, and fails official road compliance inspection.

3.3 Unauthorized Circuit Refitting

Privately changing wiring harnesses, installing non-standard lighting and high-power electrical accessories will cause circuit overload, easily trigger short circuit and battery safety risks.

4. How to Personalize Safely Without Losing Warranty

Summarize 4 core principles for URLIFE global users to upgrade safely:
  1. Only upgrade external parts: Stick to appearance, comfort and storage accessories; never touch internal controllers, batteries and limit programs.

  3. No parameter breaking: Do not exceed local legal power and speed limits, keep factory original operating parameters.
