Razor MX500 Dirt Rocket Electric Motocross Bike Review

This bike, in my opinion, has a really great concept behind it, with poor execution at times.  I found that it works well, only after a bit of freewheel modification from yours truly, though.  

I bought the bike based on its solid, durable appearance (with the exception of the rear wheel sprocket assembly).  It seems to be a common problem, as many internet reviews indicate.

After one week of riding this, my son’s rear wheel started to fall apart.  The motor would just spin and the rear sprocket would move, but the wheel itself wouldn’t move at all.

Pros And Cons of the Razor MX500

After your 3-month warranty is up with Razor though, you’re responsible to find, and pay for a new rear wheel for your bike.  

This Razor MX500 is used by my 6-year-old son, who rides it around our property all day, every day.  Overall my score rating for this bike is 4 stars out of 5.

Having  checked out the problem with the rear wheel braking, after a week of light usage, I decided to take it down to a local bike repair shop, and asked if they could fix it.  Genius!  

They welded the freewheel solid, which at the time did not seem like the perfect solution for this, but it only cost $10, which was better than paying for another wheel, plus shipping cost too.  

Two months later, I decided that this was the perfect solution to fix the rear freewheel problem, so I had the rear sprocket welded solid, and boy, was that a great decision to make!

I also investigated easier options too,  since I had a few spare rear wheels (Razor Warranty Replacements).  

I even purchased a knock-off, brand new freewheel, for $12 bucks, which looked like an ordinary bicycle rear sprocket.  This method replaces the original freewheel completely.

The new sprocket is working great, and I think it is stronger and more reliable.  My son even used the same unit for the whole summer without a single issue.  

I also recommend biweekly lubricating the lithium battery with some cheap grease spray.  Since I found a great fix for this bike, I will now rate it with a whopping 5 stars out of 5, because now it’s the perfect bike.  

The bike runs strong, but after 2 years, the front plastic internal parts may need to be replaced from time to time. Other than that, it’s to be expected since it is plastic, and the bike goes over hard terrain, with a 6 year old in charge.

Great Performance Electric Dirt Bike

Many Razor products began to populate neighborhoods all over the U.S., but Razor doesn’t stop on the sidewalk.  With the all new awesome dirt bike line, Razor brought to the line, off-road rides for people who crave dirt.  

The MX500 Dirt bike, on the other hand, is scaled down, and 100% electric, with an authentic dirt bike geometric frame and inspired Supercross styling.  

The high-performance torque motor, and super large knobby tires, tackles speed up to 15 miles per hour.   You’ll leave others deep in the dust.

I think this dirt bike is great for teens, who love the dirt bike experience, without bulldozing the bank down.  

The powerful 500-watt motor carries riders at speeds of 15 miles per hour, which is more than enough when it comes to bumpy and dirt terrains.  

Better than 40 minutes per charge, this “bad boy” can cruise 10 miles per single charge!  

Beyond all of that, the dirt bike’s riser handlebars, and its dual suspension, provides the rider with a smooth and comfortable ride without worrying about the type of terrain you are riding on.  

With an additional bonus, your teen won’t have to be flat pavement bound.  The chain driven electric motor is super quiet, so one can ride it all times of the day, without bothering the neighbours.
