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.

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.

Bike arrived as expected in a box and was very heavy. Only had to assemble the front number plate, handle bars and front wheel. This was easy and took ten minutes with the proper tools. I charged it for 12 hours as recommended and my son received it the next morning for his 7yr birthday. He is 4'6" and it is perfect size for him. Can't say enough about the quality and solid construction of this bike and it is plenty fast. He rode it for several days in a row, charges it after every ride and it hasn't died on him yet. Super fun and definitely would buy again.

I bought this bike for my 8 year old son for Christmas last year & he is still riding it just about everyday! The first time he rode it I was worried it was too big & heavy but he got right on it & took off. After seeing the smaller ones at the store I'm very glad we bought the MX500 because it seemed just right for him & the others looked too small. He knows he cannot ride it through water & takes care not to leave it out in the rain but rides it all over our hilly 16 acres with no problems. This bike is made very well & zips around fairly fast (which scared me at first but now I feel confident that he knows how to handle it). Definitely, invest in a good helmet. This bike has many pros: excellent quality, it is quiet, does not tear up your terrain, has plenty of pep!!! The battery only lasts about a hour but that has been plenty long enough for him. This is an excellent beginner bike that I highly recommend to anyone wanting to get their child ready for a real dirt bike.

My son received the 500 for christmas 2010 within 2 weeks the plastic chain guide cracked which holds the chain in place. Once cracked the chain falls off. I called and I have to say customer service is very good and they sent me out a new part ASAP. With the winter we had in the northeast he did not get much a chance to ride it much but with maybe a total of 5 hours on the bike the rear wheel and the chain would not connect to turn rear wheel, chain would spin freely around wheel. I looked up trouble shooting on line and it tells me the entire wheel at 60.00 plus shipping needs to be replaced. You cant just buy the part you need to buy the wheel, tire, and sprocket which is the problem. Again I called and because its within 90 days they sent it out to me no problem. It makes me wonder now whats next and now the 90 days are expired. I would think parts would wear with some good hours on the bike. He rides it on the street mostly. Though when it gets a little wet the motor stops working all together till it drys out. Not much of a dirt bike. But that can be corrected by some dw40 to displace the water. I am updating as of May 18, 2011 I am on my 4th rear wheel that the factory sent me. They last a few weeks then the bearing and clutch inside wheel has failed. I have to think they got a bunch of bad manufactured rear wheels. Customer service has been very responding and send the parts out at no cost but man its down more then my son uses it and I have to wonder when Razor will say to bad out of warentee no more parts. I wish the bike would work and keep working. My sons 90 lbs and he does not ride it hard. I believe the bikes are designed to run and then you need to order parts from Razor. The initial price for what you get is reasonable but they make it up on parts. But maybe its just been a bad start on my unit and this will run problem free for awhile. Personally if the wheel was not covered before I shelled out 100.00 I would have spot welded the wheel to the chain sprocket and fixed the problem for good. But let me see, maybe its just been bad luck. Like I said they do honor the warentee no problem and the people who answer the phones are very well trained on the product and try hard to speak clearly. Where they are located my guess China like everything else in manufacturing these days, but thats why its only 350 for the bike new. Final I hope last update to this review. After going through 4 bad wheel sprockets now receiving 5th rear wheel that razor has sent me no charge the last time I called in August 2011 I talked with supervisor who called me back twice and informed me that they had a bad run of rear wheel sprockets that did not hold up and this was off new batch of replacments the have now started receiving. So this last wheel I received had a different outside patters at the hub assembly on the outside then all the others if it is indeed a new setup to adress sprockets not turning wheels. I have had the same issue with this bike others have had. I will see if they corrected the problem. If not I will demand a full refund or new bike. Crazy anyone should have to deal with this. I will say as annoying this issue has been I have had no problems with razor standing behind it as I bought this back in December for Christmas 2010 and they continue to work with me sending 2nd day shipping them paying for it all. I will report back as to if this finally ends this problem. Dec 25 2011 all issues and problems I had with wheels have been resoved. Razor 4 months ago sent me new desiged wheel and its been working fine no problems at all, also the chain stays on with new wheel. I guess when wheel would hangup the chain would pop off all the time untill the wheel finally broke within a few weeks. Not anymore with new wheel designs. Razor stuck with me and did all you would hope from a company till they fix it and as you can read they stood behind their product.....It was annoying to go through but in th end a year later I am happy with bike.

At first I have to admit I was skeptical, but this little dirtbike is amazing. No problems putting it together, all parts were there. It is ridden by my 7 year old without any problems, my 9 year old also like to ride it but it is a little small for her. It goes about 15-20 MPH, faster than a thought it would go, but the kids love it. Battery lasts about an hour on a full charge; that is, an hour of constant running time. It is identical to a real dirt bike in size, weight, and appearance (except for the plastic battery cover). This is a solid bike, nothing flemsy, very well made. Your kid will love it! I would recommend for 6 to 9 year olds, however, they should master a bicycle first.

Easy to out together.

We purchased two of these for our boys ages 9 1/2 and 8. Assembly was not difficult - my husband left them in the internal packing to install the front wheel and handle bar so that the bike was stable and in an upright position. They are very well made and have some weight to them - definitely NOT cheap construction! The boys LOVE their bikes - they ride them every day. I would highly recommend this as a transition between bicycles/electric scooters and gas powered bikes/4-wheelers. Just a quick thought for any parent concerned about the inevitable crashes: Both of our boys crashed within the first week; one was a moving collision with the Razor go-cart, and the injuries were no worse than with bicycles - road rash on knees and elbows (and NO injuries to our child on the go-cart). Minor scratches and a bent foot peg were the only damages on the bike. They ALWAYS wear helmets while riding - no exceptions.

Great starter bike for kids

Stacked

fast and the product came undamaged

I ordered two of these bikes for my grandkids age 8 and 10. They love them! Unfortunately something in the rear wheel wasn't right, but the customer service was great and new parts are on the way. Once that's fixed the kids can do some more riding. Note that although they're electric they aren't toys. It can get fairly fast so helmets and gear are a must.

A great little machine to learn on. Fits my 8 yr old perfectly. Have been getting about 40-45 mins run time on flat trail. Front brakes failed after 2-3 hours of use. Front suspension design is horrible-- knocks and rattles like its missing a lower bushing. In hindsight I wish I had spent $500 more for a real mini bike = much more enjoyment at the cottage.
