Razor MX500 Dirt Rocket Bike Electric Ride-On for Teens Ages 14+, 175 Pounds Max Weight, Red – 36-Volt Battery, up to 15 Mph, 40-Minute Run Time, Twist-Grip Throttle, Pneumatic Tires

An excellent first dirtbike. Get this one. Pretty much any kid can hop on this and have a good time. I reccomend it for the five or six year old to nine or so age group. The box says like 12 or 14, but thats just a big responsible company covering their arses. Its a great learner, because its just twist and go. All hand brakes, no foot controls, which is good when learning because your feet arent always on the pegs. It's a proportional bike for kids so its not awkward or clumsy it fits them right. Dont get any smaller razor dbike, they dont have suspension. This one is very much like a real bike, suspension, handling, disc brakes, etc. Electric, but power ramps up so you cant do a wheelie. Because its electric, it is a little heavy, but that keeps them from getting too much air as well. Hundreds of hours of fun, and zero injuries. If you crash in the grass, you weren't going real fast, and are pretty close to the ground, so it dont hurt much. Rated up to like 175 pounds (again i recommend it for the 45-90 pound kid range) but ive hopped on it (210#) to put it away, and theres no problems. Batterys are standard lead-acid closed cell, so they are safe and reliable. The charge only lasts a half hour or so which is the only downside really.

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!

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!

My Grandson loves this little bike. Just the right speed for a 9 year old. Great quality.

All in all this is a great little bike. I love the look, features, ease of assembly, battery life etc. The thing I had the hardest time deciding was which model to get, meaning what size. The 350/400 is SMALL. There is no way in the world a 13 or 14 year old would be happy with this bike as the manufacturer specs say. Do not let that age spec influence you at all when deciding which one to get. This bike would fit a 7 yr old MAX and more realistically this is PERFECT for a 4-6 year old. I could see not wanting a 4yr old going 15mph but with a little practice this is the way to go for that age. Also its about 60lbs but remember all the rider has to do is tilt it up vertical, not lift the whole bike. I bought the 350/400 (350 and 400 are the same size, not sure why they have 2 numbers for same bike) for my 8 year old and it was way too small. He liked it but as soon as he saw it he thought it was small, after an hour of riding asked if he could get a bigger one. I ended up returning it and getting the MX500 which is perfect for my just turned 8 year old. I can see him riding this for a least a couple years . Its about 100 lbs but no issue at all for him to stand up. I also considered going another size up to the 650 but I think that would have been too big. Hopefully this helps. I also added some LED rechargeable lights to the front and back as it doesn't come with any type of lights. All is all a great series bike for all experience of riders, just pick the right one.

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.

So much easier than maintaining a PW50 and so far our grandson loves it. He is 6 and it is a little small for him, but we will upgrade to the next model soon enough.

I bought this item for my son for Christmas. He used it for about two weeks before it it died the first time. I contacted Razor customer support sent me instructions how to take the motor cover off and troubleshoot the throttle controller and break kill switches. This solve the first problem. About a week later the bike died again. I tried the same trouble shooting techniques again. This time the bike remained in a non-working condition. I contacted Razor customer support again and this time they noticed that my bike was built 2017 and the batteries needed to be replaced. They sent me the batteries along with instructions on how to replace them. When the batteries arrived I disconnected the battery line, charged the new batteries and connected them to the bike. The bike was still not reacting to any action. I say I connected them, but I did not install them as the Alan bolts used to secure the batteries to the frame are extremely difficult to get to and I could not remove them with the tools I had at my disposal. I connected them to see if the bike worked but could not install them. I contacted Razor customer support for a third time. This time they offered to send me a new throttle controller and kill switches. I was thinking that I bought a new bike, not a rebuild project, and asked for other options. Razor referred me to the one and only authorized repair center in Phoenix, which is about 45 miles from my house. I took the bike to this location along with the new batteries that Razor had sent me. Shop told me that the repair would take a week, maybe two if they needed to order parts. I got the bike back three and half weeks later and all appeared to be working as expected. About a week later after my son had ridden the bike enough to drain the battery we noticed that the bike was not charging. The power supply would stay in the red, 'charging' mode, and the bike power indicator would read 'full'. Problem is that as soon as he would hit the throttle the bike go to 'Low' and the bike would not move. This brings me to the fourth and final interaction with Razor Tech Support. They tell me I can again try to repair the bike myself or take it back across town to the sole repair operation in Phoenix. This bike has less than one hour of ride time on it and 4 hours of my time trying to figure out what is wrong with it and over three weeks in a repair shop. The response from Razor of you can take it to get it repaired again or buy a new one if your son still wants it is simply unacceptable. Razor customer service has been quick to respond to my many requests, for that I am thankful. That being said it is obvious that they produced a dud of a unit and I would hope they would have more respect for their customers and their customers time. Needless to say I will not be buying another item for Razor and advise you to beware of what you might if you purchase a powered Razor device...
