  • Great purchase as a first edirtbike, with 100% support from RKJ
We bought the e-dirtbike as a birthday present for my 13 years old son. It arrived earlier than the estimated time. He was able to put it together easily by watching the online setup video. The back wheel, which comes already pre installed was wobbly out of the box. RKJ was extremely understanding and shipped out a new back wheel for free, right away. My son has enjoyed this dirt bike so much. As a parent, I like the fact that the e-dirt bike is not too heavy and my son can easily load it up and secure it on the carrier on his own. The joy of riding it is priceless and the brand offers complete support with any issues along the way. ... show more

  • Great customer service and solid warranty
I had a minor question about the battery, and their tech support got back to me within hours. It’s rare to find an electric dirtbike with a 24-month warranty and such helpful staff. It makes the investment feel much safer. The bike itself is fantastic, but the peace of mind knowing they stand behind their product is why I’m giving it 5 stars. ... show more

  • High-Performance Electric Dirt Bike
Experience the thrill of riding with this powerful electric dirt bike designed for performance and durability. With its aggressive black and red design, strong frame, and high-traction off-road tires, it's perfect for riders who want both style and capability.

  • Real stopping power and rugged tires
Safety was my main concern, but these dual hydraulic disc brakes are incredibly responsive. I’ve ridden other electric dirt bikes with mechanical brakes, and there's no comparison. The fat tires bite into loose sand and mud perfectly. It’s a heavy-duty dirt bike electric option that feels very secure under my 220lb frame. Excellent craftsmanship! ... show more

  • Electric Dirt Bike
Great gift. Love the different speed settings to get use to the bike. Really like that it is electric. Definitely wear appropriate safety gear as it goes as fast as a real motorcycle.

  • My first e dirt bike and I love it!
I was nervous about switching to electric, but this electric dirt bike for adults is so intuitive. No gears to worry about, just smooth power. The throttle is very responsive but not ""twitchy."" It’s much cleaner than a gas bike—no oil leaks or loud exhaust. If you're looking for your first electric dirt bike, this model is the perfect entry point. ... show more

  • Perfect for both me and my teenage son
Love the three speed modes on this electric dirtbike. I keep it on the highest setting for my commute, but I can dial it down to 22 MPH when my teen wants to ride. It’s the most versatile electric dirt bike for adults and teens we’ve found. The assembly was a breeze—took about 20 minutes since it arrived 90% pre-assembled. Truly a family-friendly machine. ... show more
