Description

Where it sits in the Technic range

At 139 pieces, BASH! is one of the compact models in the Technic line, and that is a large part of its appeal. You get beams, connectors and axles in an amount that fits an afternoon of building and a small corner of the table. If your only experience of Technic is the huge vehicles, this is a gentle way into the pin-and-beam style of construction, where the model takes shape one assembly step at a time. The instructions stay manageable as a result, so you pick up how the model works almost in passing while you build, without having to hunt for the next step.

A dark palette with red accents

Black, dark bluish grey and light bluish grey carry most of the model, and red provides the contrast. The result looks technical and slightly rough around the edges, which suits a name like BASH!. For your collection the mix is useful as well, because black and the two greys turn up in nearly every Technic project and combine easily with parts from other sets you may already own. Dark models also show off every small structure nicely when you leave them standing under a desk lamp or on a shelf for a while after the build.

How much variety is in the box

The 139 pieces include 46 different part types. That is a sensible ratio: plenty of repeats among the standard elements, but enough variety to keep the build from feeling monotonous. The parts list on this page shows every piece with its colour and quantity, so you can quickly check what you already have in your bins and what you would still need if you wanted to rebuild it. For a small Technic set this is a good value, because you get to try many different kinds of connection with very little effort and a modest pile of parts.

Life after the build

Technic elements are easy to repurpose, since axles, beams and gears fit into many homemade designs. The “What can I build?” tool on Bricoria shows which other models you could assemble from your collection once you take BASH! apart again. A set of 139 pieces therefore doubles as a small starter stock for your own mechanical experiments, not just a one-off model. That is especially useful if you plan your own constructions and want to know beforehand which beam lengths and pins you have available for them.
