In this video I finally put my custom Razor RSF650 up against the Electro & Co ETM RTR the way these mini bikes actually get used—out on a real group ride. Both setups are 72v, and on paper that sounds like they should be close… but once you’re rolling with a pack, you start noticing the differences fast. I’m paying attention to how they launch, how they hold speed, and how they feel when you’re trying to keep up, pass, or recover after slowing down. I’m not just doing a parking-lot pull and calling it a day. A group ride shows you the stuff that matters: stability, throttle feel, how predictable the bike is in traffic-like situations, and whether it’s fun or sketchy when you’re riding around other people. If you’re deciding between building a Razor RSF650 or grabbing an ETM RTR, this is the kind of comparison I’d want to see—same vibe, same ride, real-world pace. The big takeaway is simple: “faster” isn’t only top speed; it’s how the bike performs when you’re actually riding it with others.
