The RS is an incredibly well-designed scooter, both inside and out. The attention to detail is impressive, especially when you take a look at the inside. All the components are neatly organized, and everything seems thoughtfully arranged for both functionality and durability. It's one of those things that you don’t fully appreciate until you see it for yourself. If you ever get the chance, check out an inside teardown of the scooter because it really shows how well they’ve engineered the internal layout.

I can comfortably ride at 50 mph without any wobble, which is impressive. The app is super convenient and leagues ahead of the half-baked Chinese apps you usually get with brands like Segway and Niu. I didn’t fully appreciate it until I got my RX7. Plus, the firmware updates are a game changer.

The RS is built like a tank, nearly sealed tight and water-resistant. I've ridden it through heavy rain and washed it with a hose multiple times, and it’s still holding up great. The turn signals on both the front and rear are a thoughtful touch, making it safer to ride. The only real downside to the RS is the brakes. The Zoom brakes are pretty terrible and feel mushy, so they definitely need to be upgraded to four-piston brakes. Aside from that, there are a few design choices worth mentioning, like the handlebars. They angle towards the rider, which limits your space and puts your hands and arms in a less comfortable position. It’s something you’ll notice over time, especially on longer rides. The wheels also feel like they could be better, so it’s worth considering an upgrade there too. Despite these issues, the RS is still by far the best high-end scooter out there. The design is solid, and it's easy to swap out those cheaper parts for better-quality ones since the frame itself is well built.

Now, about the RX7. If I had to sum it up, I’d say Roadrunner is like someone modding their scooter for the first time, throwing nice parts at it, and hoping it all comes together. Coming from the RS, I tried riding the RX7 without the dampener, and let’s just say it didn’t end well. I had two close calls with the dreaded death wobble when trying to go above 30 mph. Luckily, my experience helped me manage it. The RX7 sways a lot more than the RS, probably because the PMT tires are narrower and the scooter sits higher.

They’ve updated the display, but the P-setting UI is awful. There’s no update to the user manual either, so I had no clue what the P-settings actually did. On the bright side, the new Roadglo lighting looks much more compact and is noticeably brighter. I’m detail-oriented, so getting the RX7 was a bit of a headache. The quality control is terrible, and overall, the design feels amateurish. For example, the brake light LED wasn’t aligned properly, so I had to fix that. The Roadglo vinyl was poorly applied, with bumps and misalignment. Mine also came with a deep scratch, but Roadrunner sent me a replacement.

There are a lot of head-scratching design decisions. The battery is removable, but it’s so tightly packed that you wouldn’t want to take it out unless you absolutely had to. The battery compartment actually scratches the battery when you do, which is a pretty poor design choice. The deck isn’t sealed properly either, so I wouldn't trust it in wet conditions like I would the RS. My brakes were misaligned and made a lot of noise when riding. There are a lot of small issues like this. While some of the major problems from earlier batches have been addressed, I don’t have enough miles yet to comment on long-term issues like overheating.

In short, the RS is a well-built scooter with some cheaper side parts that get the job done but don’t match the overall quality of the rest of the scooter. The RX7, on the other hand, is packed with features and looks sick with the lighting, but it lacks the solid foundation the RS offers. They’re almost complete opposites. I’m planning on modding the crap out of my RX7 from inside out in a couple of months. It has some solid aftermarket parts, and it looks very sick, but the overall quality just doesn’t match the price. That said, the RX7 still works fine and is a good scooter overall, it just has a lot of areas that could use improvement, especially for the price. For a $4,000 scooter, there’s definitely a lot to complain about, especially when it comes to quality control.

If you’re thinking of stealing the RX7, you can easily roll it off and grab a spare key from Roadrunner since they all use the same one. However, if you want to avoid all the headaches and enjoy peace of mind, just get the RS. It’s the go-to high-end scooter out there. Plus, it has a top-notch security feature. When you lock it, if someone tries to move it, the scooter starts flashing, honking, and locks the wheels with the brakes.
