Kit Review

Straight build + Stickers

* A Build Custom released in 2014 Mega Ride Launcher and the Machine Rider released in 2018 have been repackaged and combined into a single kit, so please note that most of the review is the same as before, with the exception of the additional compatibility shots added at the end.

Two kits from the Build Custom series have been combined into one.

This kit is the 1/144 Option Parts Gunpla 20 (Ride-On Set). It's a straight repackaging of the Build Custom Mega Ride Launcher and the Machine Rider so please note that most of this review is the same as the original, with the exception of the added collaboration shots.

The Mega Ride Launcher is a sub-mecha that pairs nicely with the Zeta Gundam series, and can be used in various configurations with HG kits — as a firing weapon, a backpack, or a flying vehicle. The Machine Rider is a unique transforming bike that can be used with a wide range of HG and Figure-rise Standard kits. For more detailed info, I'd recommend checking out the reviews for the original individual kits.

It's a meaningful release in that these Build Custom kits have been reprinted in a combined format. Both are solid enough in terms of quality, so if the style appeals to you, they should be a fun build with plenty of ways to use them. :-)
