    • Great starter bike for a little one.
The media could not be loaded. My son is about 50 pounds and this thing is perfect for him. It doesn't take off like a rocket, but can get up to a good speed pretty quick. It makes a great starter bike to learn on before trying a gas bike where you have to learn gears and clutch etc. It is very simple to operate. There is a twist throttle on one side, a hand brake on the other. That's it, nothing else to it. The instructions for the battery are to keep it fully charged and always plug it in after use even if you didn't use it much. This makes me think it has the kind of battery that has a memory. We plug it in after each use and so far he hasn't been able to drain it in a single riding session. The assembly was super easy, You only have to attach the handlebars and the front fender. It comes with the tools you need also. My oldest is 11 and she was too big to fit her legs on the pegs without her knees hitting the handlebars, but she could still ride it just fine as long as she held her legs to the side. So it has plenty of power. ... show more

Review Image by James James
Easy to assemble, and excellent sturdy build. I was initially skeptical that my oldest kid would be too big at 9 years old, but he fits just fine as does my 7 year old. They have a lot of fun on this, and the battery life has been excellent. It's easy to use and would be good for kids probably 5-12 years in age. ... show more

    • Help on Sizing This Bike
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. ... show more

    • Great starter dirt bike
Santa brought this for our nine year old. He could not have been more excited when he saw this under the tree. Having charged it the full 12 hrs, the bike was ready to roll and it did not disappoint. Everything worked well and the charge held longer then we expected. The speed and maneuverability are exactly right for a nine or ten year old. Learning to use the break instead of ones feet are the biggest challenge but the breaking works well so once mastered all ok. Open space definitely makes it easier when learning. Being a good cyclist made it possible for our son to ride this right from the beginning. He has used this everyday since Xmas. Hopefully it continues to work as well months to come. So far the best present he has ever received. ... show more

    • Great Quality!
Great Product! My son is 7 and there is a missing market for this age group. Power wheels are slow and boring and for them and bog down with more weight. This is fast enough that its exciting but not so fast that he gets seriously hurt. (We've already taken a few spills) I will say that it is quite heavy and the one time he was unable to lift the bike up off his leg so parental supervision is required. I think it's very small for the age group it recommends. My 12 year old tried it and while enjoyed it as well looked like a giant sitting on it. I was more worried about her being top heavy and falling than my son. With the weight limit I took a ride and I've got to say it I was impressed that it didnt seem to bog down even with me on it. This bike is super easy to assemble. And feels very sturdy and of great quality. The tires are rubber air tires unlike cheap plastic tires and seamless goes over different terrains. However, it does take the full 12 hours to charge the first time and I feel it took almost as long to charge each time after that. My son rides for about 10 to 20 minutes at a time, many times throughout the day and I feel the buttery does last almost all day this way. Overall, this is totally worth the money for many hours of enjoyment and the happiest kid in the world. ... show more

    • Buyer Beware
I bought this electric dirt bike for my grandson as a Christmas present. After he opened it and was charged it for the recommended amount of time he took it outside for a ride. It ran for approximately 6 minutes then stopped working. We took it back in and put it back on the charger thinking it didn’t charge all the way. The next day he tried to ride it again and it lasted for 4 minutes (I timed it) this time. I contacted the seller and let them know what was going on and they offered to exchange it, refund us or give us a discount. I chose to return it for a refund. They sent us a shipping pre paid shipping label and said I would get a refund when they received the package. Perfect, no problem, everything was good. Until we got a message from them saying they were refunding $135 and charging a restocking fee of over $200 because the bike had been used. Of course it’s been used, for approximately 11 minutes, until it didn’t work anymore. How else would we know the bike was defective if it wasn’t used, makes no sense. I will never buy this bike again and I will never buy anything from this seller again. I would give a rating of 0 for this seller but I don’t have that option. ... show more
