Check the road before starting and look all around. Also, when you’re with friends on bikes, it’s much safer to ride behind, not next to, each other. Where one road meets another, you should take even more care. Slow down and check both roads. Use your eyes and be careful.

Check your bike often. Do all the parts work properly? Is there enough air in your tyres(轮胎)?

Size, so ask for help when you buy it.
