    • Fast in all ways.
Color: Dark Black
Review Image by Wesley Milligan Wesley Milligan
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! ... show more

    • Best Cruiser E Bike!
Color: Dark Black
The media could not be loaded. This is by far the coolest e bike on the market! The installation was not too difficult but it's an absolute blast to ride. Great quality, very quiet, affordable, and has pretty good torque. This bike performance really well on the road. Just not quite sure if there should be sounds on the turn signals, but definitely worth checking out! ... show more

    • Great e-bike, Big time Fun
Color: Dark Black
Bike is amazing to ride for those looking for a easy feel. Bike arrived with a snapped front brake line but customer service was quick to respond and send me new full assembled brake line so I didn't need to bleed the line. So much fun to ride with my daughter on her bike.

    • Everything I wanted it to be and more!
Color: Green
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! ... show more

    • Very heavy
Color: Purple
The bike is supposed to be made out of aluminum which makes bikes lighter. However it took two Fed-ex people to get it in my house. I’m shipping it back without opening it. I’m a healthy 70 year old and thought it would be fun to ride but didn’t figure on it being too heavy. There is no mention of weight in the advertisement. I just have to figure out how to get the bike to UPS store. There was no option to have UPS to pick it up like there is for other returns. ... show more

The media could not be loaded. This chopper is an exceptional machine! It's gorgeous, it's stylish, it's very comfortable, it's so fast! I absolutely adore this ebike, it's everything you ever need! I got the purple, it's nothing but a head turner, and customer service is amazing and so helpful with a couple questions I had, get this bike before it's sold out or price goes up, you won't regret it. UPDATE...... I loved my first bgx so much I bought another one! As you can see it is the blue one which is gorgeous it's a bluish purple iridescent and, they did a couple upgrades on this newest version they put a another motor in it which has a lot more torque just as fast they put another brake light on it which is a little better than the first one and they change the turn signal light horn mechanism which is a little more clicky and tactile which I personally like, these bikes are uncomparable to any other bike I've had they are the best e-bikes out there you can't go wrong with customer service with the looks of them and the price I give this bike and the company 5 plus Stars! ... show more

    • Fantastic bike
Color: Blue
Review Image by Nick Nick
I absolutely love my Bigniu BG-X electric bike! It performs exactly as advertised, offering a smooth and powerful ride. While I do get slightly reduced mileage compared to the advertised range, this is because I tend to run it at full throttle without using the pedals—so no complaints there. The bike has been a joy to ride, and customer service has been excellent. They responded quickly via email and were able to resolve minor issues caused by shipping with no hassle. My only suggestion for improvement isn’t about the bike itself but more about the design. I wish the bike came with pre-engineered connections for adding aftermarket accessories like brighter blinkers, tail lights, or other visibility enhancements that could run off the existing power system. Having that flexibility would make an already great bike even better! ... show more
