CDX Blocks Roller Coaster models are building block construction kits that let you build a roller coaster that really works, and that you can run over and over again. Just like the real thing, once the car reaches the top of the initial hill, it is designed to traverse the whole track back to the starting point, using gravity and potential energy in the most fun way possible. All of our roller coaster models are very mechanical in operation, with a gear shaft and crank to create that thrilling sense of the initial hill climb, and a unique smoothly operating track system for the downhill and thrills to follow. The Sidewinder blazes new trails. This amazing ride takes you up and over on a modern looping roller coaster. Modeled after contemporary steel style coasters, the Sidewinder twists and turns its through its compact and fun layout that includes a full vertical loop. At CDX Blocks, the emphasis is on PLAY. Our Roller Coaster models possess a high degree of playability and interaction after the build that our customers love.

Lots of bang for the buck! *by on Reviewed in the United States November 16, 2020* This is my first "non-Lego" brick set. Figured it would be pretty tacky but I wanted another coaster for my grandkid's amusement park. What the heck - cheap but you get what you pay for, right? Boy was I wrong! This is a great set!Pro - absolutely excellent value when compared to "the real thing". High quality components fully compatible with the high-priced system. Well engineered and worked great the first time I tested it. Fun build. The coaster cars are genius. The rail system is unique and I like it.Con - The rail system is unique and I hate it (huh?). A real pain in the ass. Having said this understand that the material used is a reasonably flexible plastic that's pretty rigid over short distances - think of the rail as a sideways 'U" with the open side facing out. It bends fairly well from side to side but DOES NOT LIKE to bend up and down, i.e. against two closed sides. Curves aren't a problem but ups & downs take much foul language to keep in place. Constructing the loop will allow you to use every four-letter word you know in millions of different combinations. Just know it can be done!I used the rail straight out of the box so next set - Yes! I'll get them all - I'm going to pull the rail first, uncoil it and see if it will relax a little. Maybe a good bake in the sun? I motorized mine (simple) with a Lego power functions motor and battery pack and it's a blast! Two thumbs up! ### ⭐ This Sucks *by on Reviewed in the United States January 21, 2024* I could not assemble this. I consider myself a pretty decent lego builder but this was a very difficult challenge. the whole thing is very flimsy and can break with the slightest movement. the track would not stay in place and was constantly snapping out of place over and over again. It took me 4 hours of extremely stressful work just to snap in the pieces on the loop because they kept snapping out. the supports fall down lots of the time as well which makes the whole thing even harder to assemble. after countless hours of stressful work i finally finished it, and it couldn’t even completed the course because it ran too slow. the instructions are very unclear. i went back to check it every step to make sure i had done everything right and felt each track piece to make sure they were snapped in, and they all were. there were also no instructions on how to attach the motor we ordered separately. don’t waste your time or money. the only good thing about it is that it looks cool. ### ⭐⭐⭐⭐ Finicky, but it works. *by on Reviewed in the United States April 30, 2026* A fun and semi-realistic lego-compatible roller coaster set.Everything is easy as it gets until you reach the track section. You must be precise with the ties, and on sections with tight bends, you must hold the rails in place beyond each connection point. Otherwise it’ll warp or snap off. Doesn’t contain spare parts. ## Frequently Bought Together - CDX Blocks: Sidewinder - 825 Pieces, Building Brick Set, Gravity Powered Looping Coaster Model, Promotes STEM Learning - CDX Blocks: Motor and Power Supply - Battery Operated Motor to Automate CDX Roller Coaster Brick Building Sets - CDX Blocks: Cyclone - 900+ Pieces, Building Brick Set, Gravity Powered Roller Coaster Model, Promotes STEM Learning --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ie/products/173143791-cdx-blocks-sidewinder-825-pieces-building-brick-set-gravity-powered](https://www.desertcart.ie/products/173143791-cdx-blocks-sidewinder-825-pieces-building-brick-set-gravity-powered) --- *Product available on Desertcart Ireland* *Store origin: IE* *Last updated: 2026-07-11*
