With a high-torque chain-driven rear-wheel drive motor, this bike delivers smooth, rider-focused performance without the mess of gas, so you can go green while you go fast. Comfort and control meet head-on with soft rubber grips, a double-crown fork, and adjustable riser handlebars let you dial in the fit and stay steady on the terrain. Twist-grip acceleration puts the throttle where your instincts are, while hand-operated rear brake bring confident stopping power. Folding metal foot pegs and shatter-resistant fairings add durability for real off-road riding.

Some assembly is required but once it’s together, it’s time to leave the pavement behind and own the trail.

Review: A Well-Built and Fun Off-Road Ride - Powerful, Quiet, and Surprisingly Durable — Perfect for Off-Road Fun As someone who enjoys outdoor rides but wanted something electric and compact for my daughter, the Razor MX500 Red Dirt Rocket has exceeded expectations. It delivers impressive power, quiet operation, and just enough edge to make you forget it’s not gas-powered. ⚙️ Performance & Speed Don’t let the "youth" label fool you — this bike packs a punch. It easily handles gravel, dirt, and small hills, and the chain-driven motor with high torque gives it real muscle. I clocked top speeds close to 15–17 mph, which feels fast when you’re riding something this nimble. 🔋 Battery Life On a full charge, I get around 35–40 minutes of continuous use, depending on terrain and rider weight. It takes about 8–10 hours to recharge fully, so I usually plug it in overnight. 🛠 Build Quality This isn’t a toy — the steel frame, dual suspension, and large pneumatic knobby tires make it feel like a real dirt bike. It’s stable, well-balanced, and absorbs bumps smoothly. The front and rear disc brakes also work great and give you solid stopping control. 🧑‍🤝‍🧑 Who It's For Though marketed for teens, it comfortably supports up to 175 lbs. I’d say it’s best for: Teenagers 13+ who are responsible riders Adults under 170 lbs looking for funl off-road ride Beginners wanting an intro to dirt biking without gas or noise 👍 Pros Surprisingly powerful motor Smooth ride with good suspension Durable and well-constructed Quiet and environmentally friendly Great value for the price 👎 Cons Long charge time No headlight or reflectors (consider mods for visibility) Slightly small for taller adults 📦 Final Verdict The Razor MX500 is an outstanding entry-level electric dirt bike for anyone wanting thrills without fumes. It’s well-built, performs reliably, and offers just enough punch to feel exciting. Highly recommended for teens or lightweight adults looking to tear up the trails in silence.
Review: GREAT DIRTBIKE! - This is an awesome dirtbike for the price! It's so much fun and works great for littler kids. It goes about 20 mph and it works great on our dirtbike path which is up and downhill. The battery last pretty well but best to charge at night. It's so awesome to see the kids zipping around the trail and having the best time ever. It feels really safe and that was a big factor for us in deciding between the gas and electric dirtbikes. I highly recommend this!

### ⭐⭐⭐⭐⭐ GET THIS FOR THE KIDS!
*by L***H on December 10, 2025*

Bought this a year ago for my 5 year old for a Christmas present. 1 year later he still uses this EVERYDAY! Set up was easy. He’s now about 4 foot tall and 60lbs and still enjoys it just as much as the first day! Great product. NO SUSPENSION WHAT SO EVER! Never the less my son tries to jump curbs with it. The speed setting is honestly perfect as we live inside city limits and it can’t get away from him! Perfect “first dirtbike” experience!
