The Latest, Most Remarkable Achievement in Solar Assist Bicycles!

The BEM® Savitré™ Vibe 26" Solar Assist Bicycle looks majestic and tall - it stands out amongst other vehicles on the road. This 26" bike is aesthetically more appealing compared to the smaller diameter (20 or 24") wheel bicycles. The solar panel (with its longer dimension = 25") looks relatively small in comparison to the large - 26" diameter wheel. Hence the solar panel looks more elegant when mounted on the 26" solar assist bicycle.

With the change to a smaller diameter freewheel and with an increase in wheel diameter to 26" in the design of solar assist bicycles, one can now travel at a speed of 25 km/hour in the solar (pedal) assist mode, with very little battery discharge! Up from the earlier 18 km/hour! You don't need to go any further up, as 25 km/hour is the speed limit for bicycle trails and bicycle lanes! It is, thus, possible to achieve a higher speed of 25km/hour with a bigger diameter (26") wheel without multi speed gears.

The five solar (pedal) assist levels in a 26 inch solar assist bicycle offer better control of the ratio of solar energy to metabolic energy at different speeds! To ride at 25 km/hour, all you need to do is shift up to Solar Assist Level 5! Assuming that you are pedaling on a bright sunny day, it is the most wonderful combination of human calories and solar Watts.

The calories burned by the rider to deliver the metabolic energy in the Solar Assisted Pedaling mode @ 25 km/hour goes down from 320 kcal/hour to 200 kcal/hour. The pedaling effort does not only reduce considerably, but also becomes steady or flattens out across different slopes/ inclinations. Of course this is only when we wish to not drain the battery. One is always free to choose to reduce metabolic energy input even further by substituting it with solar energy and draining the battery even more; or at the extreme end, choose throttle mode to bring the calorie (metabolic energy) consumption down to zero!

Ride a bicycle powered by the BEM® Savitré™ solar energy harvester and be proud to have done your bit to address the triple planetary crisis facing humanity, namely climate change, pollution and loss of biodiversity. Only in this manner can this innovation be jointly exploited to help India break away from the clutches of the 'American Dream' and join the environmentally friendly bicycling nations that promotes bicycle trails and lanes to keep global warming under check (< 1.5 ℃)!

Speed Calculations on the 26 inch Single Speed Solar Assist Bicycle

Wheel diameter = 26" = 66.04 cm. Hence, the wheel circumference = πD = 3.14 x 26 = 81.6814" = 207.47 cm = 2.0747m.

At speed of 25 km/ hour = 0.41666 km/minute, or = 416.667 m/min, the speed of rotation of the wheels can be calculated as follows:

Wheel rotation speed = 416.66 / 2.0747 = 200.829 RPM (revolutions/min) =3.347revolutions/sec.

The gear ratio = 16 teeth (Freewheel sprocket) : 45 teeth (Chain ring / Chain wheel).
Hence the speed of the Chain ring/Pedals = (16/45) x 200.829 = 71.41 RPM (revolutions/min) = 1.19 revolutions/sec. This speed is quite comfortable and achieved with less effort in the solar assist pedaling mode.

Solar Assist Level Shifts for Best Performance in Solar Assist Mode (for bicycles without Gears).

Speed Range (km/hr) Solar Assist Level

0 -25 0 For Un assisted Mode (Only Metabolic Energy; No Solar Energy Assistance)

1 - 5 1 Max Speed 5 km/hr for Solar Assistance

> 5 1 For Un assisted Mode (Only Metabolic Energy; No Solar Energy Assistance)

6 - 10 2 Max Speed 10 km/hr for Solar Assistance

> 10 2 For Un assisted Mode (Only Metabolic Energy; No Solar Energy Assistance)

11 - 15 3 Max Speed 15 km/hr for Solar Assistance

> 15 3 For Un assisted Mode (Only Metabolic Energy; No Solar Energy Assistance)

16 - 20 4 Max Speed 20 km/hr for Solar Assistance

> 20 4 For Un assisted Mode (Only Metabolic Energy; No Solar Energy Assistance)

21 - 25 5 Max Speed 25 km/hr for Solar Assistance

> 25 5 For Un assisted Mode (Only Metabolic Energy; No Solar Energy Assistance)

Reverse the sequence for a downward shift for a smooth decrease in speed. Simply freewheel and let the speed drop without application of brakes to conserve energy and get the best performance.

Charging time from solar panel : < 4 to 5 hours, typically 1 hour
The BEM® Savitré™ Vibe 27.5" Solar Assist Bicycle looks far more majestic and aesthetically appealing compared to the smaller diameter (26") wheel bicycles, since the solar panel (with its longer length = 25") looks relatively smaller in comparison to the 27.5" diameter wheel. Hence the solar panel looks more elegant when mounted on the 27.5" solar assist bicycle.

BEM® Solar-Bicycle Description

The BEM® सवित्रे™ Savitré Vibe - Solar bicycle is different from all other electric vehicles with respect to its charging needs. The Solar bicycle does not need to be plugged into an electric socket for charging! No need to hunt for an electric socket at your destination or place of work. Simply park the bicycle with the solar panel facing the sun for approximately 4 hours to recharge the battery of the e-bicycle after 25 kms of daily travel.

Harness solar energy even while travelling. During day travel, the DC motor of the Solar bicycle usually draws only 80% to 85% of the total current requirement from the Li-ion battery while the Solar panel supplies the rest (15% to 20%). Reduced burden on the battery means longer life of the battery. The slower charging process over 6 hours under the sun is also recommended to enhance the battery life. (In sharp contrast, fast charging from electric outlets reduces battery life).

Looking for a low loss charging solution for your E-bicycle? A 230 Volt AC to DC conversion is inefficient. Introducing the higher efficiency DC to DC (Solar to Battery) conversion with Maximum Power Point Tracking (MPPT) for faster charging with a smaller solar panel.

Once the LCD Panel is ON and lit, you may press on the power button to select one of the following 4 display modes:

To begin your ride in the Solar (Pedal) Assist mode, step on the pedal. After acquiring the desired speed, press the '+' button to increase the level of Pedal Assist that suits you. To lower down the pedal assist level press on the '-' button.
To begin your ride in the Throttle mode, simply twist the throttle handle in an anti-clockwise direction. Keep the throttle position steady for about 10 seconds to enter the cruise mode - to cruise at a steady constant speed. The LCD Panel will display 'P' to confirm entry into 'cruise mode'. To exit cruise mode, simply rotate the pedals forward, or apply any of the two brakes or twist the throttle once again.

Salient Features of BEM® Savitré Bicycles :

A 2.5 inch LCD Display that displays the Speed, Odometer - Total Distance covered in km, Trip Distance in km & battery charge status.
A 5 speed PAS (Pedal Assist) control that gives the rider an ability to choose the level of assistance that is needed from the battery while pedaling.
Cruise Control: After twisting / rotating the throttle handle by a fixed degree and by maintaining a steady speed for a time duration greater than 5 seconds, the motor controller would enter the 'Cruise Control' mode (indicated accordingly by a symbol 'P' on the LCD Panel). Thereafter, the rider is free to release the throttle handle while the motor controller takes over the function of maintaining the set speed or 'cruise control mode'. The motor controller would exit the cruise control mode when any of the following conditions get satisfied: (a) Any of the brake levers are pressed, or (b) The Throttle handle is again rotated, or (c) The Pedals are rotated.
A Strip LED Tail Parking Light mounted on rear for safety. Tail Parking light goes ON when switch is turned ON, regardless of whether day / night, for safe riding in all weather conditions.
Detachable plug and socket arrangement for the Hub motor for easy wheel removal in case of tire replacement or puncture repairs.

Head-light + Horn

Provides additional Safety to the rider particularly at night on roads with merged traffic.

Three Operation Modes in BEM® Savitré Bicycles :

Throttle Mode: Switch ON the Power by turning the key clockwise. Gently rotate the throttle handle anticlockwise to accelerate. Retain the position of handle rotation to cruise at the desired speed. Let go off the handle to allow it to get back to the original (zero) position to cut off battery supply to the motor and free wheel - cycle continues to move due to inertia. With a 8.7Ah Battery one can cover a distance of 20 to 25 km in this mode
Pedal Assist Mode (PAS): Switch ON the Power by turning the key clockwise. Do not use the Throttle handle. Instead press your foot on the pedal. The Pedal Assist Sensor (PAS) will detect your pedalling speed and assist manual power with battery power. The PAS mode allows you to travel the same distance with less manual effort. Battery gets drained less in the PAS mode in comparison to the Throttle mode, thereby enabling one to cover larger distances. With a 8.7Ah Battery one can cover a distance of 30 to 35 km in this mode.
Manual Pedal Mode: Switch OFF the Power by turning the key anti-clockwise. This would disable both PAS and Throttle modes. The bicycle gets transformed back to a human powered, pedal driven one. This mode is particularly useful to safely return back home, when you run out of battery power. The 8.7Ah Battery does not get drained in the manual pedal mode.

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

Solar Bicycle Overview

Bicycles are the most common and most numerous (> 2 billion) vehicle amongst any kind of vehicle whether human powered or motorised ever produced by mankind. Invented over 2 centuries back (by the German Karl von Drais in 1817), today we see a major transformation - solar bicycles.

Currently, solar bicycle is the only electric vehicle that provides a fully sustainable, environmental friendly, motorised solution to one's travel needs (upto 25 kms per day).

Go cycling! Roam the remote country side! Venture out to areas where there is no access to electricity or petrol pumps! Go where no man has gone before with a Solar Cycle!

Truly Sustainable Living: Be totally off fossil fuels and electric grid. Zero running cost. Travel upto 25 kms/day with a 40W panel attached to your cycle. Use Solar. Save Mother Earth!

No Registration or Driving License required: Can't get a driving licence for your under 18 teenager? Current regulations state that those between the age of 16 to 18 can obtain a license for driving a 2-wheeler with engine capacity less than 50 cc. Many teenagers aged 17 years or less are observed to be illegally riding a registered vehicle, with engine capacity of 100 cc or higher, at high speeds contributing to higher rate of accidents on Indian roads. Best answer is to ride to school with an environmentally sustainable solution - a solar bicycle - whose speed is limited to 30 km/hour.

Bicycle to Work: Wish to make a transition to a healthy lifestyle? Don't have time to go to a gym? Ride a Solar cycle to work. Can choose between manual pedalling, power assisted pedalling, or full power throttle without pedalling with a solar bicycle.

Bring Your Own Panel: As the BYOD (Bring your own device) policy is becoming more popular, carrying your own panel to work has even more advantages. No need to search for a charging point at work. Simply park the vehicle under the Sun and the battery will silently get charged while your work.

Safety First: In sharp contrast to a fast charging process from the electric utility's ac mains that has resulted in numerous vehicles catching fire, the solar charge process is an safe and elegant one, that is gentle on the batteries and enhances its life too.

Charge while you ride: Keep the Solar charger switched ON while you ride along with your panel. The solar panel will supply approximately 15 to 20% of the BLDC motor's needs while you ride. This means that the battery would be supplying only 80 to 85% of the energy and thus getting drained less, again enhancing the battery life. This also means that you can cover larger distances after a full charge.

Pedal your way back: Run out of battery power? Unlike other e-vehicles you do not get stranded in the middle of nowhere. Pedal back home.

Low Loss / High Efficiency Charging Process: When you charge the battery from a 230 Volt ac electric mains, an AC to DC conversion takes place which is inefficient. This means high temperature - low reliability operation, or requirement for forced cooling or bigger heat sink for the charger. Many AC to DC chargers are also seen to inject harmful harmonics into the AC system. Unlike this, the Solar to Battery charge process is DC to DC which is more efficient, which means that the charger can be smaller in size, more reliable, no need for cooling fans, less noise, etc.

Optimum Charging Process: Unlike other chargers, the solar charger is microcontroller based and intelligent. The ARM controller chooses an optimum - Maximum Power Point Tracking (MPPT) point for the DC to DC (Solar to Battery) conversion for efficient charging with a smaller solar panel that can be carried on a bicycle.

Charge in the Parking Lot Under the Sun: Staying in an Apartment or an Upper Floor? With Lithium Batteries getting placed inside the bicycle frame it becomes more and more difficult to charge the battery from an electric ac mains point; the entire bicycle needs to be lifted to the Apartment. Unless, you opt for the far more convenient alternative solution - Solar charging in the parking lot under the Sun!

Unique E-vehicle: No other E-vehicle other than a Solar Bicycle can boast of all or any of the above unique features!

Silent Operation: Unlike an Internal Combustion (IC) engine that 'explodes' once every 4 strokes, a BLDC motor offers silent and smooth operation.

Easy Start: An Internal Combustion (IC) engine needs to be cranked to start either with a manual kick or with a battery of a high capacity. The solar bicycle has a simple start procedure - simply rotate the throttle handle. No kick start. No mis-firing. Saves your knee ligaments!

Centre Stand: - An Aluminium Alloy centre stand helps take the weight of the solar panel more evenly than a side stand to keep the bicycle in balance in an upright position

Tilt Mechanism - An innovative tilt mechanism for the solar panel is designed around the spring loaded grip of the bicycle carrier. It gives an ability to offer the desired tilt to face the sun for faster charging. The carrier spring also absorbs shocks on a rough terrain such as a mountain road and thus helps protect the delicate solar panel from getting damaged.

Features for Safer Riding: The retrofit adds safety features such as a powerful headlight, a loud horn, rear view mirror, a continuously ON tail light at the rear to ensure that the bicycle gets noticed by the vehicles behind.

Low Cost to become Environmentally Friendly: Riding an EV is not truly environmentally friendly. The low cost BEM Solar bicycle gives you the satisfaction that you are doing your bit to address the triple planetary crisis facing humanity, namely climate change, pollution and loss of biodiversity.
