Schwinn Tango Review. Overall, I liked the value for the dollar but the performance of the bicycle was way below par due to designed limitations. Top speed is around 10 mph unless you are Lance Armstrong (BMX type gearing).verall, I liked the value for the dollar but the performance of the bicycle was way below par due to designed limitations.

Bismuth is a non-toxic heavy metal with a specific gravity of 9.71 (when alloyed with 3 percent tin). Compared to lead with a specific gravity of 11.12, Bismuth is 87 percent as dense as lead. Steel, with a specific gravity of 7.86, is only 71 percent as dense as lead.
Bismuth is a brittle, crystalline metal that occurs in its native state. It has a white coloring with a pinkish tinge. Of all the metals, bismuth is the most diamagnetic and has a very low thermal conductivity.It also has the greatest electrical resistance when placed in a magnetic field, a trait called the Hall effect.[See Periodic Table of the Elements ].ismuth is a brittle, crystalline metal that occurs in its native state.
