Supercycle bikes are made by Asian (probably mostly chinese, vietnamese, malaysian...) factories who produce cheap bikes for markets all over the world.

There is nothing wrong with cheap bikes, per se, but much of the meager cost of producing Supercycles goes toward crappy rear suspension systems, cheap disc brakes, generally nonfunctioning suspension forks.

A $300 supercycle can be considered a waste of $300, where a simple $300 bike shop hybrid or mtb can be a very nice budget bike.
