There is almost zero long-distance biking infrastructure in the DFW metroplex, and drivers tend to be hostile to bicyclists. When I biked (casually and recreationally), I would stay on the sidewalks as much as I could, when they existed - which largely limited me to suburban and semi-urban areas.
There do exist huge and long bike trails, but they only connect arbitrary points of the city - imagine New York, but with all but two subway lines suddenly removed.
Most roads in Texas cities are extremely unfriendly for bike traffic.
