Typically they are independent (self-planted, self-lead, and stand alone) non-denominational community churches with names like 'Church on the Way', '{your town} Community Church', 'River of Life Church', 'Living Word Church', etc...they are Christian churches that adhere primarily to scripture and not intsitutions or denominational doctrine. Their personality comes more from the senior pastor's style than from an affiliation with a denomination.
Small pentacostal, charismatic, evangelical, fundamental, denominations like "The Vineyard", Four Square, Bretheren, can also be considered 'bible' churches.
In all cases, they're independent with an emphasis, ostensibly, on teaching the entire bible as written, and not doctrine or denomination.
