SOLAR BICYCLES:  BEM® SAVITRÉ™ MPPT SOLAR ON

Welcome to the exciting world of Solar Bicycles. 

Buy a Solar Assist Bicycle  only to satisfy one or more of the  following four criteria ...
... (a) Love & Passion, (b) Health,  (c) Environment, or (d) Safety.

... if you have love and passion for bicycles and enjoy pedalling to work,  school or groceries. Buy it only if you are health and fitness conscious and wish to lead a healthy life, or if you are an environmentalist and wish to reduce your carbon emissions. Or if you are concerned about your safety and desire safety features & lights on your bicycle. 

A Solar Bicycle is NOT to be confused with EVs and other powered vehicles! It is to be considered as an extension of a regular road bicycle designed to offer solar energy assistance while pedalling to lower the pedalling effort, to make pedalling lighter, more fun, more enjoyable, and at the same time to make the ride safer with the numerous  in-built safety features such as brake light, tail light, head-light, etc., all driven by solar energy.

On World Environment Day, Sunday, 5th June 2022, Baroda Electric Meters Limited proudly dedicated its  indigenously developed BEM® Savitre  'Solar Bicycles' and 'Solar Tricycles ' to India and to the world. Since then the assembly and roll out of the world's first  sustainable human transport vehicle has commenced in its works located at Anand, Gujarat, India. 

A brand new 26" regular or MTB bicycle from a reputed manufacturer of customer's choice retrofitted complete, with the basic configuration consisting of a 250W BLDC Hub Motor, Electronic Motor Controller, Rechargeable Li-ion Polymer 200Wh Battery,  40 W Solar Panel, BEM Savitre Solar MPPT Battery Charge Controller, Head Light, Tail Light cum Brake Light, Horn & other Fittings, and 3 operational modes (Throttle, Pedal Assist, Manual Pedal), is offered for an all inclusive (inc. GST) ex-works price of ₹25,200 (or USD$ 260 or EURO 240) only! The price includes cost of a brand new bicycle and has no extra or hidden costs. Due to local demand, it is currenlty available only at the Factory Store. 

Solar Bicycles and Tricycles are truly a novel and innovative concept. It is probably the only vehicle developed and commercialised so far that generates its own energy that it (the vehicle) consumes. As proud innovators and manufacturers of the solar cycles, we suggest that readers compare it with other vehicles (ICE vehicles or EVs).

BEM Savitre Solar Cycles and  Solar MPPT Controllers 

BEM® Savitre™ MPPT Solar Charge Controllers / Battery Chargers can be simply be attached to Solar Panels placed under the Sun to charge up rechargeable batteries at the fastest possible pace - i.e. in minimum battery charging time. These are 32 bit ARM Cortex microcontroller based chargers with true 'Maximum Power Point Tracking' (MPPT) algorithms that enable it to extract maximum power from a solar panel of a certain capacity (Beware of modules without tracking ability, or simple PWM modules, in the market, labelled as MPPT!) . The MPPT Solar Charge Controllers are particularly useful in remote areas  for applications that need battery power far away from the electric grid. Different models can be used for charging Li-Ion Batteries for wide range of applications ranging from E-bikes or E-bicycles to Rechargeable Lanterns & Torches. BEM® Savitre™ MPPT  Controllers have been designed with inbuilt protection and controlled operating modes for high reliability, quick charging and longer usage life of the rechargeable batteries. 

Basic Configuration for All BEM® Savitré Solar e -Bicycles (No extra Cost):

Three Operation Modes: 

Tip: Apply brakes only when  needed. Applying brakes unnecessarily wastes energy.

Brake Wire used to adjust the Tilt Angle of the Solar Panel for faster Solar Charging. 

Solar Panel also works well as a Mud guard to prevent rider's clothes from getting soiled.

The Innovation behind BEM® Solar Cycles?  

It has taken mankind two hundred years from  the invention of the first human driven vehicle - a bicycle, to the development of a truly environmentally sustainable vehicle - solar cycle.  

To convert an ordinary (human powered) bicycle into an environment friendly (motor powered) solar bicycle the major challenge is designing with the primary source of power - namely the solar panel. Due to the light weight (<20 - 30 kgs), size, and 'center of gravity' (CG) constraints associated with a bicycle, it is not feasible to fit an overly large sized solar panel on the bicycle. The BEM® सवित्रे™  Savitré - 2 Amps MPPT  Solar Charge Controller, developed in-house, indigenously, gives an ability to a relatively smaller sized solar panel to charge the rechargeable battery at a fast rate. The  BEM® Solar bicycle is fitted with a medium sized 40W, 12V Solar panel and yet, the charge controller is able to deliver approx. 1 Amp of charging current to the battery. A 32 bit ARM microcontroller that runs a Maximum Power Point Tracking (MPPT) algorithm gives the charger an ability to extract maximum possible power from the Solar panel and feed the same to the rechargeable Li-ion battery. 

Tip:  Ensure that the solar panel is facing sun, avoid shadows, and keep the panel surface clean for best performance.   

We have chosen Savitré as the name of the Solar MPPT Charger. Accordingly, we have name our rollout of Solar Bicycles as Project Savitré.  The name Savitré originates from the Mantra (name of Surya or Sun God) - ॐ सवित्रे नमः Oṃ Savitré Namaḥ, meaning - one who produces everything. Savitré  also has a  corresponding  Asna  (Step) in Yoga - namely Padahastasana - a variant of Uttanasana or 'Standing Forward Bending' asana in modern yoga as exercise and as shown in the emblem alongside.
