To reduce the risk of back strain, a bike must be set up properly for your body. Visit a bicycle shop where a professional can help you determine which bike is best for your frame. When purchasing a bike, there are four significant variables that must be addressed:
1. Correct frame size should leave at least one to two inches of space between the top bar and the rider's crotch when the rider straddles the bike with both feet flat on the ground.
Adjustable Frame Bed
2. Seat height is right if the rider's leg can almost straighten out completely when the pedal is at the bottom of its arc. When pedals are in the three and nine o'clock positions, the kneecap of the forward leg should be right over the pedal. If it's not, slide the seat forward or back accordingly.
3. Seat position should be angled so that the front part is slightly upward.
4. Handlebars should be level with or just below the top of the seat. If you place your elbow against the tip of the saddle, the tips of your extended fingers should just touch the handlebar.
The type and quality of bicycle that you buy can matter a great deal. For example, a racing bicycle's low-drop handlebars place greater strain on the rider's back and neck, whereas mountain bikes have straight handlebars that allow you to sit more upright. Plus, they have fatter tires that absorb more shock and provide more cushion for the ride, a good thing for bad backs.
