What format does this book follow and what standards does it reference?

All 3D-LABS engineering books follow a practice-first structure: each chapter is built around worked examples, engineering diagrams, and real-world applications. Where applicable, content references Indian Standards (IS codes, BIS), international standards (ASME, AISC, IEC, IEEE), and India-specific regulations such as IGBC guidelines for green construction. Every formula includes units, assumptions, and the applicable standard edition.

How do I access this book after purchase?

eBook PDF: Instant download — a secure download link is delivered via email and your 3D-LABS account dashboard immediately after payment confirmation. No shipping wait. Lifetime access included — re-download anytime. Paper Book: Printed and shipped to your delivery address in India. Expect standard courier delivery timelines.

Is this book relevant for Indian engineering practice and IS codes?

Yes. 3D-LABS books are specifically written for Indian engineering context. Content includes Indian Standards (IS 456, IS 800, IS 1893, SP 46, etc. where relevant to the topic), Indian industry norms, and practical examples from Indian project environments. This distinguishes 3D-LABS books from generic international textbooks that may not reflect Indian code requirements or local practice.

Who authored this book and what is their expertise?

This book is authored by the engineering team at 3D-LABS — a multi-disciplinary engineering consultancy with offices in Trichy (Tamil Nadu), Hyderabad, and London. 3D-LABS provides engineering design, analysis, and consulting services to industry, giving its authors direct, current knowledge of engineering practice. Books are reviewed for technical accuracy before publication. 3D-LABS books are used by 10,000+ engineers and students across India.

What is the difference between the eBook PDF and the Paper Book?

The eBook PDF is a digital file: instant download, searchable, print-friendly, accessible on any device, lifetime re-download. The Paper Book is a physical printed copy shipped to your address — identical content, ideal for desk reference and annotation. The Paper Book is priced at ₹700 more than the eBook PDF to cover printing and shipping costs.

This Electric Two-Wheeler Engineering eBook from 3D-LABS is written for engineers and students who want a clear, practical reference they can apply immediately.

Electric Two-Wheeler Engineering: Scooter to High-Speed Bike is the definitive engineering e-book for EV two-wheeler powertrain design, covering motor selection (PMSM, BLDC, AFPM), battery pack design, controller sizing, and type approval per AIS-156 (FAME-II, India) and UN ECE R136 (electric motocycles). Written for engineers at two-wheeler OEMs, Tier 1 suppliers, and startups working on L1/L2/L3 category electric vehicles.

What engineering standards does this e-book cover?

AIS-156 Issue 2 (FAME-II type approval requirements for electric two-wheelers, India), UN ECE Regulation 136 (electric power-train safety for L-category vehicles), IS 16086:2018 (BIS standard for electric two-wheelers), AIS 038 Rev 1 (electric vehicle battery pack — safety requirements), and ARAI (Automotive Research Association of India) type approval procedures.

Frequently Asked Questions

What motor technology is most common for electric two-wheelers in India?

Hub-mounted BLDC (Brushless DC) motors are used in 78% of Indian electric two-wheelers (SMEV 2023 data) due to low cost and simple control. Mid-drive PMSM (Permanent Magnet Synchronous Motor) is used in performance segment (>45 km/h, >4 kW) for better efficiency (η = 92–96% vs. 85–90% for BLDC hub motors) and regenerative braking above 40% energy recovery. AFPM (Axial Flux Permanent Magnet) is emerging for compact high-power applications (>10 kW).

What is the FAME-II range requirement for electric scooters in India?

Under FAME-II (AIS-156 Issue 2), electric two-wheelers qualifying for subsidy must achieve: minimum range 80 km at 40 km/h constant speed (IDC test), minimum top speed 40 km/h, and minimum battery energy density 100 Wh/kg. Vehicles above 250W motor rating must comply with UN ECE R136 for type approval under the Central Motor Vehicles Rules 1989.

What battery chemistry and pack voltage are used in Indian electric two-wheelers?

Lithium Iron Phosphate (LFP, LiFePO4): 85% of new Indian EV scooters (2023) — 3.2V nominal per cell, cycle life 2,000+ cycles to 80% capacity. Pack voltage: 48V (16S LFP, common for low-speed scooters), 60V (20S), 72V (24S for mid-range). NMC (Li-Ni-Mn-Co-O2): 3.6V nominal, used in performance segment for higher energy density (200–250 Wh/kg vs. 120–140 Wh/kg for LFP). IS 16086 requires BMS with overcharge (>4.25V/cell), over-discharge (<2.5V/cell), and thermal runaway protection.
