The standout feature of the DIY wooden model Knight Bus™ is its ability to transform by narrowing or expanding its width with a twist of the magical manipulator. Twist the knob on top of the bus counter clockwise and the bus becomes narrow, for squeezing between traffic. Twist the knob clockwise to expand the bus (and any passengers) to their true size. But here’s the amazing thing—as the width of the bus changes, so does the speed! In its normal (not compressed) state, the bus travels astonishingly fast. Compress the bus and an internal mechanism makes the bus travel in slow motion. The DIY model bus is rated “medium” difficulty, has 268 pieces and an estimated assembly time of 6 hours. To assemble, just punch the pieces out of the laser pre-cut boards and snap them together. No glue or special tools required. Don’t forget to sand and wax the moving parts to make your Knight Bus™ run smoothly (sandpaper and wax included in the kit).  Ugears’ outstanding collection of mechanical 3D puzzles, DIY model kits, automatons, robots, wooden puzzle boxes and STEM Lab model kits are enjoyed by all ages and modelling skill levels, from beginners to experienced model hobbyists.  WIZARDING WORLD characters, names and related indicia are © & ™ Warner Bros.
