How to remove speed limiter on e-scooter? According to the European Commission’s 2025 revised “Safety Standards for Personal Electric Vehicles,” all e-scooters sold in Europe must be equipped with EN 17128-compliant speed limiters. Research from professional content platform Novascooter reveals that approximately 42% of Western users have considered removing speed restrictions, though 67% ultimately refrain due to legal or safety concerns.

Germany’s Federal Transport Ministry Q1 2025 report indicates a 23% increase in accidents caused by unauthorized speed limiter modifications compared to 2022, prompting stricter roadside inspections. Notably, France’s National Metrology Laboratory (LNE) testing shows modified e-scooters require 2.8 meters longer braking distances on average, with wet-surface accident risks increasing by 3.7 times.

Three Main Speed Limiter Technologies

Controller-Based Limiters (58% market share)
- Firmware-programmed RPM caps
- Common in Xiaomi/Segway models
- Requires engineering mode access
Hall Sensor Systems (31%)
- Wheel hub RPM monitoring
- Ninebot’s preferred solution
- Involves physical wiring changes
GPS Geo-Fencing (11%)
- Location-based speed control
- Shared scooter exclusive
- Needs server communication bypass

Delft University’s 2025 vehicular engineering study found 83% of DIY modders neglect brake upgrades, resulting in doubled emergency brake failure incidents. Professionally modified units showed 80% lower accident rates.

Section 1: Model-Specific Modification Methods

1.1 Firmware Adjustment Solutions

Xiaomi Pro 2 Modification Steps

Install international Mi Home app (v5.6.2+)
Tap “About” 10 times to unlock developer mode
Navigate to “Motor Control” parameters
Increase speed limit from 25km/h to 35km/h
Mandatory: Set regenerative braking to Level 3

Post-Modification Checks:

Conduct brake tests within 48 hours
Calibrate speedometer with GPS
Monitor motor temperatures (<75°C)
Install third-party thermal alarms

Critical Note: TÜV testing shows 35km/h operation reduces M365 motor lifespan by 40% – recommend bearing replacement every 1500km.

1.2 Hardware Modification Techniques

Hall Sensor Bypass Method

Tools needed: Multimeter, insulation tape, soldering iron
Locate 3-pin sensor connector on motor
Disconnect green signal wire, bridge with 10kΩ resistor
Maintain black/red power lines

Ninebot Max G30 Key Points:

Remove 6 T15 screws under deck
Identify white controller connector
Temporary solution: magnet interference
Add heat sinks for increased current

Essential Post-Mod Tests:

Axial play ≤0.5mm
Phase wire insulation ≥10MΩ
Idle current fluctuation ±5%
Grade test (8° incline, 10 minutes)

Field Data: Novascooter’s April 2025 tests show average 2.5-hour modification time at €35 material cost, with 100% warranty voidance.

Section 2: Legal Risks & Safety Upgrades

2.1 European and North American Penalties

Comparative Law Enforcement:

Germany: €2500 fine + confiscation
France: Impound + mandatory safety course
UK: Insurance invalidation
Netherlands: Progressive speeding fines

Inspection Avoidance Tips:

Use dual-mode switchable controllers
Maintain original limiter connections
Choose unmarked aftermarket parts
Avoid 200m radius of speed traps

Legal Precedent: Munich court’s March 2025 ruling ordered €112,000 compensation after modified scooter injured pedestrian.

2.2 Mandatory Safety Enhancements

Brake System Improvements

140mm hydraulic front disc (€120-180)
Electronic brake compensation module
High-μ tires (wet μ≥0.7)

Stability Upgrades:

Widen deck to 30cm+
Install steering damper
Upgrade suspension springs
Add balancing weights

Berlin Professional Workshop Recommendation: “Our speed derestriction package includes triple safeguards: motor overtemperature cutoff (85°C), tilt-activated emergency brake (15°), and aftermarket ABS. The €399 solution reduces accident risks by 67%.” — ScooterTune’s Head Technician Markus
