    Unfortunately, the product turned out to be worse than I expected, there are loud squeaking noises coming from the wheels, the brake system broke down in two weeks, there were problems with the electrical system again... I do not recommend this product.

    I was so excited to finally get an electric bike and this one is perfect. It was delivered in a well packaged box with lots of protection. It was easy to pull out and unwrap all the pieces. It comes with all the tools you need to put just a few pieces together. I had to put on the front fender, tire, headlight and pedals. Each piece went in smoothly with no problem. Make sure to put the tire on with the brake disk going into the brakes. Also put the handles into the bar before lifting up to close because the cords won't let you do it the other way. Just lock the seat and handle bars. The clamps hold strong and nothing moves once they are closed. The frame feels very sturdy and strong. Bike is easy to fold up and will save some space. It is also easy to put in the back of your vehicle when folded. The very large tires are perfect for going off road and is easy to ride. The best feature that I love is the assist mode. It has 5 levels. Each level will assist you to achieve a certain speed. So when you turn it on 1 it will not move forward until you start peddling. While you peddle it will assist you to keep a speed around 5 mph. When you stop peddling the motor stops. So you really don't have to struggle to ride this bike. It is the easiest ride you can have. You can also push down on a lever to make it go up to 20 mph if you want. The acceleration is perfect. Not too fast and not too slow. If you want to get some exercise just turn it all off. Gears shift smooth and I barely notice the change. It has no problem getting you up hills by itself even close to 20 mph. At first, I was worried that 20 mph wouldn't be fast enough but it is. It will still go faster if going down hills or by you peddling. Brakes aren't too strong that it will throw you off but they squeak a little. Bike is not quiet but not loud either when the motor is running. I don't really notice it after a while. The wind in my ears was louder. The display is nice showing speed, miles driven and battery level. The battery can be charged while it is in the bike or you can pull it out to charge it. The battery was dead when I turned it on and took about 5 hours to charge. The grips on the handle are unique and feel great. The seat is larger than most bikes and feels good. After about 10 miles though, it still gets a little uncomfortable. I don't regret getting this because it is a lot of fun.

    This is worse the a one star. The weld on the handle bar broke as you can see in pictures it was a quality control issue. The weld did not penetrate during manufacturing. It caused the weld to break and handlebar came off bike which caused the wheel to turn and flip the rider off the bike. This product is dangerous I want to return but do not feel I should pay restocking fee.

    The product is not as described. Does not go the distance as indicated, the screw that was installed by the manufacturer already fell off on its own. It does not pass 19/hr as indicated on the description as well. I’m 180lbs so not because I’m overweight

    Fun Ride, Easy to Take with You

    If you’re looking for an outdoor activity, biking in general is a lot of fun, but the addition of an ebike makes the level of entry a bit easier, adds a new element of fun, and it’s great exercise . This bike has wide tires, 500w motor that accelerates up to 20mph, and a foldable frame that I was able to get into my chevy malibu believe it or not. This bicycle was easy to put together out of the box. It came with all the tools needed and only the front wheel, fender, light, pedals, and handlebar needed to be assembled. All the bolts were pre-installed where they were supposed to go so no annoying blister packs with labeled parts. I can’t compliment the packaging enough, there was plenty of effort put into making sure the bike ships without scratches or damage. Each area of the bike had a zip tied foam covering which kept it in great shape from shipping. The bike is a bit tall for me, luckily the seat and handle bars are easily adjustable with a quick release lever that lets them slide up or down and easily locks back in place. The handle bars are comfortable to use, no issues reaching any of the controls. The throttle is a thumb throttle, not a grip twist type. I don’t know if I have a preference, but the thumb throttle was easy to use. It’s installed on the left side which is the side you should be using for hand signals which means you can’t signal to turn while still using the throttle. Probably fine in most cases but if your using the throttle uphill, you’ll lose speed unless you pedal through it. It also worth mentioning that it does come with a kickstand that was already installed with a rubber tip to keep your floor from getting scratched up. I’m new to ebikes so there was a bit of a learning curve for me. There’s a nice “transmission” lever/button on the right that helps with getting up to speed. Just like a car, work your way from the lower gears to the higher gears. The “E” part of this is the pedal assist. Besides off, there are 5 levels of assist. I describe pedal assist as help up to a certain speed, then beyond that speed you’re on your own. After about one rotation of the pedal, the motor kicks in and will help you up to a certain point, on pedal assist 1 I find that I’m doing most of the work, but it does help me get going up to speed from a stop. On pedal assist 5, it’s 0 to 19ish mph in a few moments without much effort at all, which can be a bit daunting at first if you’re not used to it. The quick forward acceleration wouldn’t be ideal on a trail where you may have a turn coming up, so plenty of practice with pedal assist is recommended before you go trail blazing for the first time on an e-bike. A large appeal for me is the folding part of this bike. Two quick release levers and you’re folding. Handlebars fold down next to the tire and the frame folds in the middle so that tire meets tire. The frame has a little stand on the bottom to help support the bike upright in a folded state. You can then put the bike in the rear of your SUV or, in my case, a 4 door sedan. It is a full size bike with 16” tires so it does take some strategic guidance in the back of my car, but it can be done. I do, however, recommend getting some help in that scenario, as to not damage anything. In the back of an SUV or truck, no problem getting it loaded in. As for other features, there is a front headlight which can be turned on by holding down the + button, it adds some visibility but I’m not sure if it’s more for other drivers than your own. The display screen provides battery level, distance traveled, which gear assist mode you’re using, speed you’re traveling. You can hold the “-“ button and there’s a walk mode which propels you around 2-3mph. The disk brakes are a nice add and work great, reflectors are on both the front and back for additional night visibility. Finally, a small bike rack area on the back where you can affix you’re choice of accessory. The user manual was in color and has all the relevant information you could need from use, assembly, maintenance, and troubleshooting. As for the things that could be better. The fenders seem fairly flimsy and cheap. I don’t like how the front one attaches to the bike, in fact, I’ve already lost one of the bolts that hold it in the wire support that runs along the back of the front fender. The key ignition placement, on the bottom of the frame, is a bit inconvenient to find with the key. On the top or side would make it a bit easier to find.

    This eBike is feature packed and also packs down into a convenient portable package! There are a couple minor features that I believe would take this pro bike to the next level, but it’s pretty well packed for its price point. Assembly was fairly straightforward, nothing too exciting, it took me about 45 minutes. The bike comes well packaged, there’s sufficient foam protection, packing materials, and zip ties to keep things protected and from rubbing on each other during transit. They include a nice little tool kit that gives you every tool you need to assemble the bike. The instructions are laid out well, but a couple of the pictures could be a little clearer, and some of the steps could have used an additional helpful tip. I struggled mounting the front tire while trying to balance the bike, but after finding an instructional video on YouTube, I realized I could have just flipped the bike over and accomplished it with ease. Once you get everything assembled, you need to make sure you charge up the battery to full before the first use of the bike. This process can take up to 5.5 hours, so you may need to save the inaugural trip to the next day if you assembled in the evening like I did. The keyhole is in a little bit of an awkward position (underneath the battery), and the manual isn’t super clear about there being 3 key positions. You have a battery unlocked position, the battery locked position (which the bike arrives in), and one more partial is the actual battery “connected” setting that allows power to the bike. The bike is quite adjustable for height, so if you’re a tall person, I don’t think you’ll have an issue riding this. The bike seat has a tiny bit of “suspension” built-in, and then the front shocks are adjustable and lockable if you need to keep the shocks from moving. Overall riding impression thoughts are summarized into these words: impressed and sufficient, yet a tiny bit of room for improvement. The bike is easy to operate and quick to accelerate up to speed, the motor feels very powerful, and at 500 watts, it doesn’t disappoint. However, lower speed maneuverability is a little more difficult. Just taking off at power assist level 1, in gear 1, the bike powers you right up to a few mph and you just sit there free spinning as you’re pedaling slower than what the motor is moving you at. Instead of the bike really “assisting” you, it just feels like the pedals are a throttle control. If you’re spinning the pedals, the bike is supplying power to the motor. I’d like this to be a little more hand-in-hand with actual pedaling effort instead of taking the energy I’m supplying right out of the equation. That’s the purpose of the hand throttle control. Beyond that, the other 2 improvements that could be made to the bike are regenerative braking and hydraulic braking. While onboard brakes are at least disc brakes, they are just direct cable driven, and stopping 2-300 pounds of bike and rider can be troublesome and slow at high speeds. You can’t supply enough braking pressure with your hand to stop the bike as quick as you’d like at times. Additionally, if you stop pedaling, the electric motor just turns off and you start coasting. If you could add in the ability to regeneratively brake, you would general additional energy and provide more stopping power without having to upgrade the manual braking system. These minor missed improvements don’t keep the bike from being great, but with fixing those would make a fantastic eBike. Wrapping up, one of the best features is the bike’s ability to fold up. This makes the bike super portable in comparison to more full size mountain bikes especially. While at almost 70 pounds it can be a little heavy to lug around, I was able to stuff the bike in the trunk of my car. The handlebars slide and fold down, the seat slides down, the bike folds in half, and even the pedals tuck in an extra few inches to try to be the most compact package possible. Overall, if you’re looking for a feature packed, portable eBike that’s powerful and has a great battery life, this eBike is at a great price point and will be enjoyed for the many trips to come.
