Razor MX650 Dirt Rocket Electric Motocross Off-road Bike - Yellow

Bought this about 2 years ago for my then 10 yr old son and he still rides it all the time at age 13, though he is big on it. It handles the weight well.It was pretty easy to put together. Took me about 45 min, and I would not call myself handy. Good instructions. The bike is pretty heavy duty and overall good quality. Very quiet. Speed is acceptable for an 8-10 yo, but not pokey either. The plastic wheel fenders stood up to severe beating- jumping, wheelies, numerous crashes and wipeouts before one broke. It did not affect the bike performance 😄. Battery life lasts about 4 hours of constant use. Usually charge it each night. Great bike to learn how to ride “dirt bike” style and master basic skills without a clutch or gas motor.

This is a great electric dirt bike for ages 8 and up. The bike goes about 17+ miles per hour. The battery last pretty long so they can ride it about 45-minutes to an hour. It quiet so the kids can ride it around the neighborhood without the noise that gas dirt bikes produce. When you are done just simply plug it in. It very convenient and built well.

I originally bought the MX400, but when I unboxed it I realized it was way too small for my 8 year old daughter. She is approximately 4ft6in and 60lbs. I returned it and ordered the MX650. I am glad I did. The MX650 is perfect for her height. It has working suspension, the throttle is variable and it has front and rear disc brakes. It is easy to assemble. Its light enough that she can pick it up when she crashes or falls over. It has decent acceleration and is plenty fast enough for her. Even though the MX650 is a couple hundred more than the MX400 it was worth it as she will be able to ride it for a couple years before she grows out of it, or until she wants to move up to a gas powered bike. The electric motorcycle is better for around the neighborhood as it is quiet and doesn't tear things up like a gas bike would. If your child is 7 or up I would recommend the 650 over the 400 or 350 model it is just a better bike. The build quality seams to be pretty good. The only issue I had is the bolt holding the kickstand on was stripped out so I had to rummage up a nut and bolt to hold it on.

My 8y/o son got this for his birthday and loves it. He was riding an electric scooter and was going to hurt himself.I showed him a video of kids riding this razor and he loved it and his friend has a 500. I assembled it and had it charged for his party and he took off and his Nana nearly had to change her pants. It's great if moms don't want kids to have a gas powered motorcycle.Now for the review. Assembly was pretty easy for a mechanic. Shouldn't be too hard for anyone. I did change the shock mounting hole, it has two, to raise the rear end up some and tightened the shock up a bit. Be careful installing the front wheel or you could bend the disk brake rotor. Brakes work well just a little flimsy on the rotors part.Decals are cheap and placement needs improvement but kids won't notice that. The cap over the charging port is a nice touch.Charging a 36 volt system takes a good while but if it is charged overnite it should last all day if not ridden too hard.Speed is good 12 - 15 mph depending on terrain and going by my Honda 100 speedometer.Fit and finish on metal parts is good and it cleans up easy. Don't hose it off too hard because it is electric.If anyone needs to replace batteries, which should be a few years, be careful because the wires are soldered to the terminals.You will need a good soldering iron to break them loose before you melt the battery.I think Razor has a good product line and I am very satisfied with the MX 650!

Rode the hell out of it for 2-3 months, every day, in Yosemite (working at a summer camp. It was my transportation) towards the end it would barely hold a charge but I think I got my moneys worth. If the battery held up better, Would’ve been a five. Very fun. Went 30 mph downhill. Good brakes. Good mini bike

Came quickly as Amazon orders always do. Packaging was perfect, no evidence of drops or crushing. Assembly was fairly easy, instructions were clear, took me about 20 minutes. The hardest part was lifting the box off the bike. Tires were pre-inflated. No tube or flat problems like I heard about in other versions of this bike. As a matter of fact, my son's mother purchased an MX350 for our 8 year's birthday at her home, and she had to drive an hour to get the tire fixed to save the day. After charging our MX650 for 18 hours, I took it for a ride around the neighborhood to make sure everything was working properly. I weigh about 175 and was surprised how peppy this thing is. My son has been riding this pretty regularly at our home for clips of 30-40 minutes, and I have only charged it 5 times since December. The battery has only so many charging cycles, so I'll let it get low before recharging it. He must have gotten 90 minutes out of the last charge. Highly recommend this bike. I felt an 8 year old didn't need the speed and danger of a real gas dirtbike. This thing has been fast and fun enough to keep his ADHD attention.Update November 2010: We have two of these, and both have been well used and still hold a 30-40 minute charge. Zero problems with the motors or tires too. Our boy took a few spills on his, got some gnarly scrapes, but that's to be expected. The kids don't run to use them as much as they did last December, because like any toy, this too gets old.Update September 2011: Both are still running! The kids are a little older now (12 and almost 10). The 12 year-old has become too tall (and mature :) to ride hers, so it's been passed down to the 10 year-old boy's buddies when they come over. They're not used as much as they used to be, so I feared the batteries would be shot. Not only do the batteries still hold a pretty decent charge, but I have NEVER, not once, filled the tires with air, and they're still in great shape! I may, for the first time, fill the tires to give them a little boost in speed. We moved to a more urbanish suburb with less dirt, so they're ridden on paved streets now when they're ridden. We've moved twice since we first got them. They've had a few minor spills, but no serious injuries to the bikes or kids (thank goodness). Bottom line, they've held up very well, still running excellent for a two year-old battery powered riding toy.Update October 2012: The kids are now almost 11 and 13, and they're both pretty much done with these things. Both the bikes still run! Original tires and batteries. Granted, the battery on one of them lasts about 20 minutes and the other a little longer, but the kids are bigger and heavier than they were two years ago, so that's to be expected. We sold them to someone for about $150 each for his kids, and they're very pleased. Overall, still 5 stars over our complete ownership. That's pretty darn good. Still recommend!
