Ok so I was researching e-bike or scooters for at least 3 months before pulling the trigger on this bad boy here. Building the bike was fairly straightforward if you watch the Bigniu Bike Installation video on YouTube. I watched it in .75x normal speed to make pausing it a bit easier. The bike is pretty heavy, but with a heavy duty tubular chassis like this one I’d hardly call it a surprise. The looks of this thing are top tier. I’m 6’0” 220 pounds and I fit on it quite comfortably. I’ve put about 10 miles on it so far so not a ton of ride time but I already love it. I rode it at night with the headlights on and it was plenty bright for a night rider and having blinkers and a tail light makes me feel extra safe on the road. The pedals and cranks are a bit light so I might try to adjust them to have a higher gear ratio for me, as I also ride spin bikes quite often and pedaling on this bike really doesn’t generate any speed. I also don’t know if the bike has regenerative breaking of any kind, but with a battery this size who cares. My breaks squeal a little bit under pressure but I think I just need to figure out how to adjust them. The default settings on the bike computer are set to 3 modes of pedal assist, however if you watch YouTube videos on how to change the settings, you can update the computer for up to 5 levels of pedal assist. I was hoping there was a way to increase the output to the motor to increase top speed but alas I think my top speed being my size is roughly 34-35 on flat road, and I’ve gotten close to 40 downhill before having to brake. She had more to give too. I will update in the spring with a warm weather endurance test to see what kind of distance I can get, but right now it’s sub 30 degrees outside where I live and I already know that’s going to limit the distance. All in all, I’m am super happy with my purchase. Definitely get a helmet since this thing hauls ass. Don’t wait, buy this bike. It’s awesome. I just wish there was a easier way to store it!

When I ordered the bike it gave me a delivery date but to my surprise it actually showed up 4 days earlier than expected.. (FAST). With the bike in the locked settings for speed it goes about 20mph. But unlocked it goes about 40mph. (FAST) And even sitting still it looks fast.. It was easy to assemble but there were no instructions ( I found YouTube videos ) and yes I did change a few parts to get my Black and Red look. It is comfortable to ride and did I mention it was FAST? GREAT BIKE, GREAT VALUE and GREAT LOOKS. How can you go wrong with the Bigniu BG-X!

Took a couple hours to assemble, but wow this bike is awesome and so fast! Great quality, heavy and very well made. One of the best purchases I have ever made. Didn't come with assembly instructions but you just need to watch the video.

I love this bike It scoots and boots very nicely. Great to look at, battery stays charged for a while. Plenty of power going uphill. The shocks are phenomenal, makes the bumps on the side of the road not so bad. The closest thing you can get to a real motorcycle without a gas engine. This rattle the brakes the turn signals and headlight all are extremely accurate to a big bike. Everyone who sees it loves it so I tell them all about it and where I got it, just love this thing. This bike has given me a sense of independence I could just get on it and go as long as it's not pouring rain lol. I can't say enough about this bike I recommend it to everyone. I do wish the brake light was a little bigger, and they had some accessories like saddlebags but due time. I 1,000% recommend this bike, you will definitely have lots of fun with it.

This is the most coolest thing I have ever owned. Where I live, no one has seen anything like it, even my friends who ride e-bikes. It has taken me on long journeys, to my sons which is about 25 miles from where I live and it did not even hurt the battery. It goes really strong uphill ,and we have one of the steepest hills, I still did 21 all the way up without pedaling. I LOVE this bike!!!!!!!

I’ve had this bike for almost 5 months. Lots of hype on these bikes, big 9.4 ratings an what not! Yeah it’s a cool bike! Runs really good an what not yahda yahda! So asking questions to big Niu service tech guy, pointless! If he gets back to you, it’s a week later if at all! Not please cause I had questions! Like is it normal for what sounded like my spokes on the front idle wheel and the real motor drive wheel to pop?? Cause I think mine are popping. Mind you this is only 2 months into ownership and less than 100 miles! 3 months in under 150 miles what sounds like my spokes are popping much more often and louder! Yesterday I dug into the loud continuous noise that was indeed my spokes popping and my front wheel is beyond repair and needs replaced and the 2000Watt aluminum wheel motor drive is maybe beyond repair idk yet I’m gonna see what I can do! But the spokes where they go into the inner hub part of the wheel all wallered them selves out to the point of pulling rite through wheel! I paid 2k for this bicycle only to wish I would have got one with the dual motor drive but now I got the bigniu POS that I can’t ride or best I can tell find wheel for either. Still waiting on their tech guy to text back cause they don’t take celery fone calls at bigniu! You have to text! F them fellas at bigniu! This is not how we do business!
