    • Fantastic little dirt bike!
Color: White
Bought this dirt bike for my ten year old grandson for Christmas. Having ridden one belonging to a friend, he ran around the house for twenty minutes to get this one. The hardest part of assembly was getting it out of the box. Packed very well and arrived in plenty of time for Christmas. Assembly took only a matter of minutes. Batteries arrived charged but we followed the directions for the initial charge anyway. My grandson rides to his heart's content and has never run out of charge. Being a stereotypical, he has fallen a couple of times with nothing more than a couple of scratches for the bike or himself. Great bike, great seller! Wouldn't hesitate to buy or recommend again. ... show more

    • Perfect dirt bike
Color: White
This things runs perfectly, and it is very fast. We live in a HOA and neighbors complain about kids on the gas ones so this would be your next in line for something that is comparable to a small gas one.

    • Awesome little dirt bike!
Color: White
My 9 year old has been begging me for a dirt bike, and there was no way I was getting him a gas powered one! Santa brought this one for Christmas, and it is PERFECT! Even though it is small, it is very solid and sturdy. If it was any larger it may be too heave for a young child to handle. Perfect for a beginner! ... show more

    • Good little bike
Color: White
Very easy to assemble. Product is exactly what I wanted as far as its functions. The battery however only lasts for about 20-30 minutes at a time. Overall though its a good e-bike for kids.

    • Heavy Duty Frame and Fenders
Color: White
The bike frame and fenders were a lot more sturdy than I expected. More inline with an actual motor bike. We’ve only had the bike for a little over a month. My son rides it daily and the battery seems to be holding a full charge. My son is 7 and is about the right size for this bike. There’s no way this is intended for a 13 year old (recommended age) to ride comfortably. My 14 year old son tested it and looked like a clown riding a miniature bike. It’s a great starter bike. ... show more

    • Never worked! *Update September 2022*
Color: White
Review Image by Susan H Susan H
**UPDATE!! After lots of back and forth I was finally able to be a new motor sent to me from Razor. My son was so excited to finally ride his bday present after a long 4 month wait! The battery lasts about an hour and it’s the perfect size for him (6 year old). I’d recommend the bike but not Razor customer service.** Bought this dirt bike for my sons birthday in May. He still hasn’t ridden it. When I contacted the seller I was told to contact Razor directly rather than be able to exchange it. I’ve contacted Razor on three occasions now. They’ve sent me multiple parts but none of them have fixed the issue. When you turn the accelerator it just clicks. Very upset that I wasted the money! ... show more
