All about this set

Kai’s Motorcycle Speed Race (71838) playset lets boys and girls aged 6 and up recreate fast-paced scenes from season 3 of the NINJAGO® Dragons Rising TV show. The action-packed motorcycle toy battle set features 2 ninja bike toys with moving wheels: Kai’s race bike adorned with 2 daggers, and the villainous Spectral Dragonian Scout’s demon bike. The ninja vehicle set includes 2 NINJAGO minifigures to ride the bikes: Kai armed with a translucent reveal blade accessory and 2 golden katana sword accessories, and a Spectral Dragonian Scout with a sword accessory, so kids can enjoy great imaginative play on their own or with their friends as they stage good vs. evil battles. The LEGO® NINJAGO range of sets and buildable ninja toys for kids includes dragons, vehicles and temples so fans can role-play adventures with their heroes. Each ninja playset can be created with the LEGO Builder app, which guides you and your child on an easy and intuitive building adventure. Set contains 79 pieces.

This set is perfect for any kid who either loves LEGO, the show, or just the theme in general or all together! This set is perfect for the price at only $10 you get two minifigures that are great quality and great playability right outside of the box. Great for kids and beginners. However, if you are an adult I would still recommend this set, but the two bikes might be a little underwhelming but you should still get this set for the two minifigues especially the new Kai, as he is the conplete version and only appears in one other set, the very underwhelming "Ninja Combat Vehicle" set that is NOT worth the price. All in all great for everyone with perfect playability and the builds are pretty good aswell! This shows how good Ninjago can get with their builds for young kids at a low price point! 10/10 would recommend.
