Book Description
(Cont.) From the mean power flow (charging) into the batteries per unit distance of travel and the power required by LED safety flashers, the effectiveness of the system at each speed and stopping frequency is examined. For cyclists traveling at average speeds of 10 mph or higher, the LED safety flashers can be powered continuously for stopping frequencies of 8 times per mile and semi-continuously (> 50% of the time) for stopping frequencies of at least 4 times per mile. As such, the system is determined to be potentially useful to urban commuter cyclists, who frequently perform braking operations at regularly spaced intersections and traffic signals, and who regularly travel by bicycle in low-light conditions (dawn or dusk), though usually less than 50% of the time.

Project Report from the year 2016 in the subject Engineering - Mechanical Engineering, grade: 10.00, , course: BE MECHANICAL, language: English, abstract: Natural resources conservation has become a requirement in today’s world, mainly in the area of new technology. In many rolling applications maximum energy is lost during deceleration or braking. This problem has been fixed with the introduction of regenerative braking. The Kinetic Energy Recovery System (KERS) is a system for recovering the moving vehicle's kinetic energy under braking and also to utilize the usual loss in kinetic energy. When riding a bicycle, a great amount of kinetic energy is lost while braking, making start up fairly difficult. Here we used the mechanical kinetic energy recovery system by means of a flywheel to store the energy which is normally lost during braking, and reuse it to help propel the rider when starting. The rider can charge the flywheel when slowing or descending a hill and boost the bike when accelerating or climbing a hill. The flywheel increases maximum acceleration and can perform pedal energy savings during a ride where speeds are between 6 and 5 kmph.

Book Description
Abstract: Electric bicycles are widely available in user markets. However their use as a daily commuting vehicle is limited due to the need for frequent recharging. This thesis focuses on the mathematical modeling of electrical bicycle with regenerative breaking. Basic bond graphs methods are discussed here to develop state space models for mechatronic systems. A bond graph based mathematical model of an electric bicycle with regeneration is developed in this thesis. Mathematical models are tested in simulation, generating different road scenarios. Parameters required for the simulation are calculated using an experimental setup. The thesis shows the capability of bond graphs to assist in calculations for regenerative charging. The main focus of this thesis is to evaluate simulation models against a prototype. Simulation results and road testing of the prototype indicate the regenerative braking is not only feasible, but an advantage to implement in an electric bicycle. It is shown that the distance between battery recharge is improved by as much as 10% depending on riding conditions.

Book Description
An updated edition of a classic: an indispensable companion for a new era in cycling. The bicycle is almost unique among human-powered machines in that it uses human muscles in a near-optimum way. This essential volume offers a comprehensive account of the history of bicycles, how human beings propel them, what makes them go faster—and what keeps them from going even faster. Over the years, and through three previous editions, Bicycling Science has become the bible of technical bicycling not only for designers and builders of bicycles but also for cycling enthusiasts. After a brief history of bicycles and bicycling that demolishes many widespread myths, this fourth edition covers recent experiments and research on human-powered transportation, with updated material on cycling achievements, human-powered machines for use on land and in air and water, power-assisted bicycles, and human physiology. The authors have also added new information on aerodynamics, rolling drag, transmission of power from rider to wheels, braking, heat management, steering and stability, power and speed, and other topics. This edition also includes many new references and figures. With racks of bikeshare bikes on city sidewalks, and new restrictions on greenhouse gas–emitting cars, bicycle use will only grow. This book is the indispensable companion for a new era in cycling.

Book Description
Handbook on Electric Vehicles Manufacturing (E- Car, Electric Bicycle, E- Scooter, E-Motorcycle, Electric Rickshaw, E- Bus, Electric Truck with Assembly Process, Machinery Equipments & Layout) An electric vehicle (EV) is one that is powered by an electric motor rather than an internal-combustion engine that burns a mixture of gasoline and gases to generate power. As a result, such a vehicle is being considered as a potential replacement for current-generation automobiles in order to solve issues such as:- a) Growing Pollution b) Global Warming, c) Natural Resource Depletion, and so on. Despite the fact that the concept of electric vehicles has been around for a long time, it has garnered a lot of attention in the last decade as a result of the rising carbon footprint and other environmental implications of gasoline-powered vehicles. The global electric vehicle market is expected to increase at a CAGR of 21.7 percent. Increased government investments in the development of electric vehicle charging stations and hydrogen fuelling stations, as well as buyer incentives, will provide chances for OEMs to increase their revenue stream and regional footprint. The EV market in Asia Pacific is expected to develop steadily due to increasing demand for low-cost, low-emission vehicles, whereas the market in North America and Europe is expected to rise quickly due to government initiatives and the growing high-performance passenger vehicle segment. India's flagship plan for boosting electric mobility is FAME, or Faster Adoption and Manufacturing of (Hybrid and) Electric Vehicles FAME Scheme has been authorized by the government, with 86 percent of overall budgetary support has been set aside for the Demand Incentive, which aims to increase demand for EVs throughout the country. This phase will support e-buses, e-3 wheelers, e-4 wheeler passenger cars and e-2 wheelers in order to build demand. The book covers a wide range of information related to the manufacture of electric vehicles. It includes E- Car, Electric Bicycle, E- Scooter, E-Motorcycle, Electric Rickshaw, E- Bus, Electric Truck with Assembly Process, contact information for machinery suppliers, Directory Section & Factory Layout. A detailed guide on the manufacturing and entrepreneurship of electric vehicles. This book serves as a one-stop shop for everything you need to know about the Electric Vehicle Manufacturing industry, which is rife with opportunities for startups, manufacturers, merchants, and entrepreneurs. This is the only book on the production of commercial electric vehicles. It's a veritable feast of how-to information, from concept through equipment acquisition.
