I love this E bike! My boyfriend put it together took about an hour some was already put together out the box easy to assemble. Have to say it is fast! Be careful ladies and teens, beginners if using! I highly recommend getting a helmet. I'm a beginner and I had it on level 1 which a video I saw on YouTube said beginners 1-3 it was still pretty fast for someone who hasn't ridden. Battery lasts long a couple hours. Quality is great! Definitely worth the money! Size was good for me I'm 5'3" 150lbs and it was perfect for my size! E Bike is fun can't wait to hit some trails and tracks! Now I can ride with my man! A little update it's been about a week and the shocks are making a squeaky noise when you sit on it or hit a rough spot on trails how can I fix that? The sticker says something about the nut but I'm confused 😕 can anyone help me with that? Anyone else having that problem?

THIS BIKE IS AMAZING FOR THE PRICE!! Good torque, decent throttle response (throttle def needs to be upgraded though), decent starter brakes (another thing to consider upgrading asap) and overall the looks?? 🔥🔥 best bang for value and a good starter bike all around for those looking to get into electric motocross/street stunts... I’ve even topped out at 41 on the street (NO PEDALING!!) and ridden in 100 degree weather under the sun w/ little to no issues so far (PLEASE TIGHTEN YOUR BOLTS!!!). only put down 30 miles so far so will try to update this review as I see fit!

This is a great bike and definitely lives to the specs. I purchased this bike for my son and purchased a different bike to keep up with him as I was getting tired of pedaling. The other bike had similar specs but was cheaper, and now I know why, it is no were close to this bike. This bike easily goes +30mph, tackles steep climbs like nothing and is fun to drive. The only down side I had was a noise on the suspension but it was fixed with a bit of lubricant. Very happy with this product. It is well built and worth the price.

The media could not be loaded. The bike is an amazing starting bike. It keeps up on rideouts. My only complaint is the throttle it has a bit of a delay. Downhill I’ve gone 40 mph but top speed is 35-37. Seat is kind of comfortable. Battery life is pretty good.

Won't run after 5 months of use. My chain broke so I replaced it and now when I turn it on it says error and won't run. I took it to thre separate bike shops and no one can fix it. Getting a hold of the manufacturer seems to be impossible. So now I'm stuck with the $2,000 paperweight.

If you are in the market for a E-bike look no further!!! This is the bike you want!!! It has amazing performance and has such a smooth ride. I’m always trying to find an excuse to ride this thing and it rides like a dream and very responsive. I’m 250 lbs and this thing hits 28mph no problem at all. Also, out the box, the bike come about 90% together and if your are mechanically incline you will have no problem putting it together. But it!!! Do it!!!

This bike is awesome, it has very good acceleration, I was able to get 34 mph as a top speed, and the battery lasts very long. This bike is dual suspension making it a very smooth rides over bumps, curbs, etc. This bike is a little big for my 13 year old but he still rides it fine. Overall, it was a great purchase and I definitely recommend to someone who wants a budget-friendly e-bike.
