What do you think about people riding their bikes instead of driving cars?

well i am 21. i dont have my license. i dont want a car unless it doesnt need oil. i dont mind riding my bike, but some places i cant ride my bike. i dont know how to chain up my car when i'm going to the mall, movies, or the grocery store. i feel in ways i am trapped into buying a car. anyone else feel like this? riding my bike helps with saving gas, but i can't ride my bike 30-40 miles. i can't ride my bike to work either.

At 21 Years old, insurance is going to be real expensive. At a point in your life when its hard to make decent money, Real smart people watch the value they get for their expenditures.

So, here are some tips:

consider bimodal transportation, using mass transit coupled with bike riding, either along with biking or instead of biking.

carpool and pay more than your share.

Make friends at the retailers you frequent, so they are supportive of you riding your bike.

Don't take your bike to the movies or any event schedule for multiple hours.

Join a bike club where people have learned how to overcome some of these obstacles. Tell your bike shop your goal, ask them to put you in touch trying the same things.

Dress nice, keep your hygiene outstanding. Have a little " travel care kit" for emergencies, (handy wipes, deodorant, even some cologne)

Share with your friends what you are trying to do as an experiment. gain their support.
Barter for combined shopping trips with them, maybe buying a lunch or a couple beers.

Make car shopping trips with them for heavy items, or frozen items. Make it easy and entertaining for them to support your efforts.

If this doesn't work take a cab or public transport for big/heavy items.

Learn bike mechanics and work on friends bikes for barter.

consider an electric assist bike, consider a trailer.

Can anybody tell me how is the performance of electric bikes & cars .How much economical differece?

is there as compared to petrol bikes & cars


Answer
"Performance" has several factors. We generally think of this on the basis of an IC engine. As a result we tend to think of acceleration, handling and fuel economy. With battery electric vehicles there is also a reference to the vehicle range on a charge. While "range anxiety" is not usually a consideration in an ICE vehicle I do recall a time in the Australian outback where I would have given almost anything for a petrol station.

Generally it takes longer for electrons to flow into a battery than for gasoline to fill a gas tank. Electrons will flow into an ultracapacitor far more quickly and development of ultracapacitors that can hold sufficient charge will resolve the issue. Alternatively if they can be made cheaply enough they could be included with batteries and will extend the life of batteries and enable the vehicle to be quickly charged with energy (from ultracapacitors at "fueling" stations. Presently the best that an electric vehicle can offer is less concentration on fueling. You fuel at home. It takes seconds to start and stop a charge. The rest of the time you can be doing other things. Alternatively you must make special trips to fueling stations where someone must pay attention to the fueling process.

Batteries in an BEV (battery electric vehicle) are typically low in the vehicle. This improves handling as it lowers the center of gravity. Acceleration in electric vehicles is better than ICE vehicles due to full torque starting from 0 RPM in electric motors.1

Under present economic conditions an electric vehicle can save its owner approximately $1000 to $1400 per year in fueling costs in addition to the increase in performance.2 The vehicle except for batteries has a projected life many times that of ICE vehicles, possibly as much as 80 years as compared to the life expectancy of an ICE vehicle of about 10 years. Present batteries have a life expectancy of between 5 to 10 years and may represent 1/2 the investment in the vehicle. Ultra capacitors would have an expected life that exceeds the rest of the vehicle. There is some question about whether the electric vehicle will depreciate very rapidly with little residual value or if the addition of newer battery packs or even ultracapacitors would be like adding an addition to real estate and possibly restore or even exceed the original value of the vehicle. It may be possible that the vehicles will appreciate rather than depreciate like a very few of the classic ICE vehicles. 3
