They are smaller than normal bikes.
Racing bikes are so different from your conventional bike in many ways. They are made to be a lot lighter than the average bike you see today and are made for speed. Racing bikes are fitted with minimum components the gears can range from 18 gears to 30 gears.
generally a racing BMX is built for speed, hence they are made lighter than normal bikes and also have a bigger sprocket witch enables the driver( back sprocket) to go faster.
Sometimes it is normal, to have a smaller testicle then the other.
The number corresponds with the number of gears [speeds]. Most child bikes may have three gears. Gears are especially helpful when biking up or down a hill. For most riders ten speeds are more than enough.
Yes a dwarf rabbit is smaller than a normal rabbit
First, quantify "normal". Then make normal smaller.
the fetus might receive less oxygen than normal
No it is smaller than 0
In simple terms, big gears turn smaller gears faster and small gears turn bigger gears slower. If the larger gears were in back peddling would take less force but you would have to pedal much faster to move at the same speed you do with the gears the way they are.
