If you want to cruise around the city with your kids in tow, I will send you a Bridgestone Mamachari bike from Japan. You pay the purchase price + shipping cost+ $300 for my efforts to go to the bike shop, pick out your color, put in the mail, translate the instruction manual, and answer questions.  With two bike seats, the bike costs JPY140,000.  The bike comes with lights, fenders and so much more than what you get in the USA at the moment. Hydi B is also a great bike.  This bike is a gamechanger for you if you are a mom married to your car.  I have 4 kids and commute within in 4km radius shuttling kids to schools and activities and doing regular chores and heading to meetings and works.
