single wooden frame connects front and rear wheel and makes this bicycle very affordable.

10 Other uses of motor bike.

1. Generate electricity
You need one suitable motor which will convert mechanical energy of rear wheel to electricity.




2. Lighting
You can use 35 watt of light bulb for lighting purpose with running engine.
You can also use motor bikes battery , In that case you have to use LED lights.

Survival tools for bikers

last week I was travelling to some place. Road condition was very bad .
Got rear wheel punctured and I was stranded in middle of nowhere.
Nearest mechanics was around 4-5 km away.
So I left my bike and took a auto rickshaw to bring mechanic.
Rickshaw driver told me that he can help me out and he pushes my bike using his left leg while driving rickshaw, and I was saved.
Today I brainstormed about the problem and found some of typical problem faced by biker .

1. Puncture
Driving with flat tire is very difficult because tire is very loose and tend to move right or left.
Tie down tire with rim at multiple places using thin ribbon or thin rope
Doing this you will be able to drive at slow speed for at least 3 -5 km.

2.If nearest help is more than 10 km then use this method.
Open your toolkit and remove punctured wheel  and feel the tire with some soft material like leaves
you can also use sand if its there.
Doing this you can at least get out from the situation.

3. If you have tubeless tire then carry puncture kit with you.
In tubeless punctured wheel air doesn't easily gets out. if some pin or nail is there don't try to remove it. By removing this you will let air pass from the tire.
Some time tire really get full flat.
There is tool for filling tire with air using bike engine. Tool is simple pipe which connects your engine with tires valve. In engine you have to remove sparkplug and connect one end of pipe to spark plug hole and crank the engine .Don't forgot to shut petrol valve.

Battery weak ( self start is not working)

1. Some times due to carbon deposition on switch  it doesn't get contacts made.
Put some petrol drop on it and rub.
2.Try  to bypass relay using very thick conductive wire.
This can harm your battery so try this only when there is no option.
3. Use thin and flat ribbon  to roll over tire as shown in picture
and pull one end this will rotate your rear wheel and crank your engine.
(Put bike on first or second gear)

4. If you know your bike has week battery always park bike at high hill.
Then you can start your bike while going down.
(Put on second gear and  release clutch.)
5. lie down your bike and use other bike to rotate your bikes wheel.
 

NO petrol
1.Use small bottle of petrol in your toolkit.
2.Small amount of petrol always stay in tank. Tilting your bike may help you out.
3.Put small sponge inside your petrol tank. Sponge will retain some petrol even if tank petrol is over.
 Squeeze out remaining petrol .

You have no lock for helmet.

1.Put one end of chin strap of helmet inside tank hole and lock it
2.You can use your sheet lock too for locking helmet.

Two wheeler needs shade

In India large number of population uses two wheeler for transportation. it has been experienced huge discomfort driving two wheeler in rainy season or scorching summer season. one of effort was made by BMW
c1 toward solving this problem, the first version c1 was quite hit because of novelty value though second version of it wasn't able to impress the consumer.
one of major issue involves with enclosed two wheeler is safety and usability. Making safe design accounting mishap is a huge task.
Rain protection in possible only if it is fully enclosed but you have to keep provision for leg support on both side also this protection has to be fully dynamically stable at least till 35 kmph to be acceptable.
some of tried version of enclosed two wheeler has side support wheel to provide stability while slow speed.
but these are extremely expensive arrangement ,lets see how much indian consumer can shell out for similar solution.
cost of indian two wheeler- 35000 to 120000 INR
four wheeler price-              150000 to ...above
second hand four wheeler     80000 to above
by seeing above data i can easily say one can not be able to shell out more than 20000 INR.
solving this one need to look whole spectrum of problem , legality, safety ,usability then only it is possible to satisfy consumer
