Get on your bicycle and practice these safety tips: Brake correctly by placing your hands at the ends of the levers. On a long downhill, don't stay on your brakes. This may overheat the tire rims, which could cause a blowout. Rather, tap the brakes intermittently. Don't pedal in high gear for long spells. This can heighten the pressure on your knees and lead to injury. Position the handles correctly - 1,5 cm lower than the top of the seat. Change your hand and body positions frequently. Keep your arms loose and don't lock your elbows. 0 More in Newsletters Selenium is an important nutrient More: Daily Dose: QUIZ: Can you live with only one lung?Health-in-Motion advertisement Read Health24’s Comments Policy Comment on this story 0 comments Comments have been closed for this article.
