Good luck with the warranty claim updated review
Bought this for my son, he rode it around for a while. Absolutely loved it. Good speed. Perfect for a kid that wants try his hand in the motocross world. Affordable. My issues are as followed. The tires kept going flat. We just rode on the street. They didn’t hold air very well. I bought some heavy duty tubes and that fixed the issue. Second issue is the bike just turned off and will not work anymore. I contacted then company directly and they were responsive and sent me a new throttle, brake and controller. I installed all of these and nothing worked. Took it to a local electronics guy here in my city and he told me the internal wiring is fried. No good. He said it’s cheaper to buy a new one.Contacted company again and they. Said the bike was still under warranty and agreed to send another bike. I was extremely happy about that but now they will not return any emails. Radio silence. So I’m assuming I’m just S-O-L. It sucks cause my 3 year old love this bike. And they said they would get him another bike sent out and now nothing. Will update if I hear back from them!Updated:4/21/25Just got a new bike in the mail!

Great quality
We bought this for our 3 yr old daughter. It is a very good functioning bike. It was simple to assemble. The brake doesn't function that well, but she just uses her feet. The battery life is decent for a toddler who is always forgetting to shut it off lol. She has so much fun on it!

Super dangerous throttle!
I normally never write reviews good or bad but this product deserves an immediate review. It’s my belief that this product should be a complete recall as it almost cost my son his life! While riding around my quiet neighborhood street my son who had already demonstrated great ability on his k8, ran straight off the cul-de-sac and into a yard before crashing. He was not injured and when I asked him what happened he told me the bike would not stop. I didn’t understand this till a few days later when I was riding my bike next to his k8. We were approaching a busy 40mph street and I could see he was not slowing down. I yelled and yelled with desperation in my voice for him to stop. He then yelled back “I can’t”! We crossed the busy road together and by the grace of God there was no cars crossing. I peddled next to him and saw that his thumb was completely off the throttle yet the bike continued at full throttle. I told him to hold the power button off and that was the only way we got the bike to stop. Insanely dangerous! Till this point I believed the bike to be an awesome learning tool but please learn from my lesson.

Battery didn’t last a year
Pretty decent little bike that our kid loves. Battery went bad after 11 months , requires purchasing another 75 dollar battery . Might be worth getting something with a warranty if you plan on keeping the bike for multiple kids .

This bike.... wow
My son got this bike for christmas this year. He is 2 years old. He had a typical balance bike and was pretty good at it. All his older brothers ride dirt bikes, he was so eager to join the pack, but he was too short for his electric dirt bike and not strong enough to control the weight of that bike. After looking at other electric balance bikes, I could not justify $600-$800 on a bike he would ride for maybe 2 years if I am lucky. I searched Amazon, read reviews, and ultimately decided to purchase this bike.first let me say, he loves this bike. He loves it so much he broke it 3 times. (not because it is made cheaply) because he RIDES this bike. We bought the second battery because he would drive through a battery within a few hours and want to keep going.After my husband fixed it, we reached out to the company, we were sort of at a loss. We have had the bike for 4 months. My son would turn the handle bars too far ( like allllll the way around) and the wires would pull away from the circuit board.I was hoping we could buy replacement wires and parts. But I was not expecting what we got.After emailing them they offered to send new parts but wanted to know exactly what was going on. I explained in detail and to my disbelief, they sent me a WHOLE NEW BIKE, free of charge, and I dont even have to return the old bike. They told me to keep it for parts!!!!!!!!!!!!!!!!!!!!My son, now barely 3 has transitioned to his electric dike bike. (because this bike taught him balance, throttle, and brake control) Even though he has transitioned and does frequently ride his dirt bike. This bike still doesnt sit for 24 hours without being touched. His older brothers love to ride it around to.We have recommended this bike to multiple families, 2 of which also bought the bikes, and couldnt be happier.100% recommend

Great Product AND Amazing Customer Service
We have had this bike since Christmas 2023. It gets ridden every day by a 3 year old and it is his absolute favorite.CS Review: Recently, it wouldn't turn on, so naturally we hit up customer service for recommendations to fix or replace. We received an almost immediate email back with our first steps to fix it, after the initial email, we receive one or two emails a day with new steps to fix. Some emails promised a new part, which must've been sent immediately because each part that we received was at our house within 2-3 days. This was the easiest customer service we have ever dealt with. They were on top of communication until the bike was fixed like new.BIKE Review: This bike is solid. It has the perfect levels of speed for a timid toddler or a crazy one like mine. Very easy to learn and will easily becoming your toddlers favorite toy. My three year old is very small for his age and this bike will fit him for a couple years minimum!

Was fun while it lasted updated!
Update: this company went out of their way to fix this problem, I emailed them and they sent me a part they thought could possibly be the issue. The part did not work so they are now sending us a new bike. And we are returning the broken one. Can’t recommend this company enough! They are awesome!This bike was awesome while it lasted but it now won’t turn on anymore after having it only 6 months. Super bummed especially after spending 200$ on it.
