Breastfeeding and diet. You don't need to eat anything special while you're breastfeeding. But it's a good idea for you, just like everyone else, to eat a healthy diet. A healthy diet includes:
Three-speed bicycle. The three-speed bicycle is a bicycle that uses internal hub gears at the rear wheel hub to provide three gear ratios. Typically, in low gear, the rear sprocket turns faster than the wheel; in middle gear, the rear sprocket turns at the same speed as the wheel; in high gear, the rear wheel turns faster than the sprocket.
Bike tourers often opt for three chainrings up front; the third small chainring (sometimes called a granny gear) gives you a broader range of easy gears for climbing hills with a heavy load. Pair that third chainring with a rear cassette that has a large cog with 34 teeth on it and you'll have a nice easy gear for climbing. Mountain Bikes. Mountain bikers should also gear for the hardest climbs. Mountain bikes typically have 9-11 cogs in the back and 1-3 chainrings in front, indicated by 1x9, 1x10, 2x10, 1x11, etc. Mountain bikes have traditionally come with two or three chainrings to provide a variety of easy gears for climbing. However, mountain bikes with single chainrings are now very popular.
