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.
Speed = (460 X front sprocket) / (rear sprocket). Stock bikes are generally geared to reach their top speeds at just below their power peaks in top gear (12,000 rpm for our CBR's top speed of 157 mph, with power peaking at 12,500 rpm) so as to maximize speed and allow for things such as going downhill and wind.
