The more expencive the less its weight

I and my wife have ordered each bicycle in July. Today we go picking up our new bicycles to the shop. This means it took two months to finished products. It's worth the wait because these are built specially for our physical constitutions and our tastes.

When it comes to mechanical equipment like bicycle, generally the more expensive the less its weight. My wife isn't used to ride such a lightweight machine, so she fell off at her first ride. All she has to do is practice a little.
