Electric Scooter Repair Course

Lesson 1 • Electric Scooter Types and Markets

Covers personal, commercial, and shared-fleet scooter categories and their design differences. Establishes context for repair decisions based on scooter class.

Lesson 2 • Major Systems Overview

Introduces the five core systems: electrical, mechanical, braking, control, and chassis. Provides a mental map used throughout the entire course.

Lesson 3 • Tools and Equipment Identification

Introduces hand tools, power tools, and diagnostic instruments used in scooter repair. Correct tool selection reduces damage and improves repair accuracy.

Lesson 1 • Reading Wiring Diagrams

Teaches interpretation of scooter-specific wiring schematics and connector maps. Accurate diagram reading is essential for tracing faults without guesswork.

Lesson 2 • DC Circuit Theory Review

Covers Ohm's law, series and parallel circuits, and power calculations. These principles underpin every electrical diagnosis performed later in the course.

Lesson 3 • Using Multimeters and Test Equipment

Develops hands-on proficiency with multimeters, oscilloscopes, and load testers. Accurate measurements prevent misdiagnosis and component damage.

Lesson 1 • Battery Management System Functions

Details BMS roles in cell balancing, overcurrent protection, and temperature monitoring. Understanding BMS behaviour is critical for accurate fault diagnosis.

Lesson 2 • Lithium Battery Chemistry Basics

Explains lithium-ion and lithium iron phosphate cell chemistry, voltage curves, and capacity. This knowledge guides safe charging and replacement decisions.

Lesson 3 • Charging Systems and Charger Faults

Examines charger types, charging profiles, and common charger failure modes. Diagnosing charger faults prevents repeated battery damage.

Lesson 4 • Battery Testing and Diagnosis

Teaches capacity testing, internal resistance measurement, and cell-level inspection. Accurate testing determines whether a pack needs repair or full replacement.

Lesson 1 • Hub Motor Construction and Operation

Explains brushless DC hub motor components, winding configurations, and Hall sensor operation. This foundation supports all motor fault diagnosis tasks.

Lesson 2 • Hub Motor Disassembly and Rebuild

Guides learners through safe hub motor removal, bearing replacement, and reassembly. Proper rebuild procedures restore motor reliability and efficiency.

Lesson 3 • Motor Electrical Testing

Covers phase resistance, insulation resistance, and Hall sensor signal testing. Electrical tests isolate motor faults before mechanical disassembly.

Lesson 1 • Controller Diagnosis and Replacement

Teaches fault code retrieval, input/output signal testing, and controller swap procedures. Systematic diagnosis avoids unnecessary controller replacement.

Lesson 2 • Throttle and Brake Signal Circuits

Covers Hall-effect and potentiometer throttle types, brake cutoff signals, and signal ranges. Correct signal diagnosis prevents unsafe throttle or braking behaviour.

Lesson 3 • Regenerative Braking Systems

Explains energy recovery circuits, regen braking levels, and interaction with the BMS. Proper regen setup improves range and reduces brake wear.

Lesson 1 • Mechanical Brake Adjustment

Covers cable tension, pad alignment, rotor trueness, and drum shoe adjustment. Correct adjustment ensures consistent braking force and lever feel.

Lesson 2 • Brake Pad and Rotor Replacement

Guides pad wear measurement, rotor thickness checks, and replacement procedures. Timely replacement maintains braking safety margins.

Lesson 3 • Hydraulic Brake Bleeding and Service

Teaches brake fluid selection, bleeding procedures, and caliper piston service. Air-free hydraulic circuits deliver firm, predictable braking response.

Lesson 1 • Suspension Fork Types and Operation

Covers spring, elastomer, and hydraulic fork designs and their damping mechanisms. Understanding fork type guides correct adjustment and service procedures.

Lesson 2 • Frame and Chassis Inspection

Addresses crack detection, folding mechanism service, and stem tightness checks. Structural integrity directly affects rider safety and scooter longevity.

Lesson 3 • Tire and Tube Service

Covers pneumatic and solid tire removal, tube patching, and inflation standards. Correct tire service prevents flats and maintains handling stability.

Lesson 1 • Repair Documentation and Quality Control

Covers work order completion, parts documentation, and quality control sign-off procedures. Accurate records support warranty claims and repeat-visit diagnosis.

Lesson 2 • Full Scooter Pre-Delivery Inspection

Guides a complete pre-delivery inspection covering all systems before returning a scooter. PDI ensures repair quality and customer safety.

Lesson 3 • Systematic Fault Diagnosis Process

Teaches a structured six-step diagnosis process: verify, gather, analyse, test, repair, confirm. Systematic methods prevent repeat failures and wasted parts.

Lesson 4 • Display Unit Functions and Settings

Explains display menus, speed limit settings, and riding mode configuration. Correct display setup ensures the scooter operates within intended parameters.
