Don't buy a bike with suspension, especially a cheap one. Several reasons for this...
1) Every time you add something (like suspension) something gets taken away (like better wheels or better drivetrain). You don't get something for nothing;
2) Compare the price ($60) with what you spend each month for your cell phone or internet service. Think thats equitable, or do you think that maybe you should spend more on something that could last you years;
3) If you are considering one of those bikes used, forget it. You don't know if it has been taken care of and you can't tell just by looking. When you buy used, you get no warranty and no service. If you are considering a new one, read the warranty and make sure you can live with the terms. I sure couldn't;
4) My guess is that the reviews represent how those bikes act when ridden according to the warranty limitations which is, as it reads, for general occasional transportation only. This means that they are for street use... another reason you don't need suspension;
5) Suspension is NOT for comfort. It is to keep the wheels on the ground for better handling. If you are riding "gently" there is NO reason for ANY suspension.
