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 naturally occurring metal used to manufacture solder, fishing anchors, shotgun pellets, and more. Many cosmetics and pharmaceuticals also contain bismuth in various forms. Bismuth subsalicylate is an active ingredient in many popular, over-the-counter upset stomach remedies. Bismuth oxychloride is used in cosmetics. Bismuth subgallate is an active ingredient in products used to address flatulence odor. Although bismuth exposure is common, that does not mean itâs completely harmless.
