I occasionally take a street in my town that has train tracks, and never in this entire year has my Meridian felt like it was tipping over. That is one of the reasons I like it so much, because it is stable. On my usual route around the high school I will often stop and chat, I can rest my feet on the pedals and still feel secure.
I bought mine for a pretty good price at my local Walmart. They put it together for me for free (I even tried to tip the young man who assembled it and he refused, even though he went above and beyond, taking it out to the parking lot and putting it in my SUV)
The downside at Walmart is that one has to buy it through Walmart.com, unlike other bicycles which are available at my local Walmart store for inspection, the Meridian has to be ordered online.
My road bike which I got from Bikesdirect cost more, but the Meridian is to me every bit as valuable in its own way.
