Which is better? Bicycle with big tires or small tires?

Are large tires hard to control? Small tires needs to pedal more than large tires?I need bicycle that can ride safe at street.

some magnets are permanent, some are temporary. so it depends on if its prmanent or temperary. permanent- always magnetized temporary- can vary from seconds to years

if it is a temporary magnet, then it is a matter of time if it is a permanent magnet, it is as long as its magnetic domains are aligned. so if you don't touch it, then it will stay that way forever. plus, it wont work if you heat it up.

It is generally permanent unless it's exposed to extreme heat or high magnetic field. The magnetization of sedimentary layers magnetized as they formed by the earth's magnetic field identify magnetic pole reversals going back millions of years.

Any bike can be safe on the streets - that's up to the rider, not the bicycle, or the tire size. THE most important thing in any bicycle is the right sized frame to fit the individual person. Once into adult sized bikes, they are measured by frame size - not wheel or tire size. There are many types of bikes from BMX bikes to mountain bikes to road bikes. All depends on WHERE HOW you will be riding. Hybrid bikes are popular today because of their versatility. They have an upright sitting/riding position, are faster on the streets than a mountain bike, yet can still handle light off road trails. I highly suggest you Google 'bicycle shop' and your zip code. That brings up every real bike shop in your area. Go visit a few. They can help you pick out the right bike for your particular riding style. Much better than talking to an associate at a discount store.
