Style: E2-750w 48v 13ah
It's been a fantastic experience so far! The bike is incredibly well-built, with a sturdy high carbon steel frame and a sleek black design that turns heads wherever I go. The 750W brushless hub-drive motor is powerful enough to handle both casual rides and off-road adventures with ease. While the max speed is advertised as 28MPH, I've been consistently getting around 26-27MPH, which is still impressive and might vary for others. One of the standout features for me is the full suspension system. The front fork absorber and rear suspension work together to provide a smooth and comfortable ride, even on bumpy terrain. The 20"×4.0 fat tires also contribute to the bike's excellent stability and traction. The brakes are solid and reliable, giving me the confidence to ride at higher speeds without worrying about stopping power. The dual hydraulic brake system ensures that I can come to a quick and safe stop whenever needed. The 48V/13Ah removable battery is another highlight. It charges relatively quickly (6-7 hours) and provides a decent range, allowing me to cover long distances without any issues. The battery is also UL2849 certified, which gives me peace of mind regarding its safety. Overall, the Bike is a great investment for anyone looking for a versatile and stylish e-bike. Whether you're commuting, exploring new trails, or just enjoying a leisurely ride, this bike has got you covered. Highly recommended!

I chose this ebike because of its design. After about 100 miles ridden on it, I would say that it’s perfect for both relaxed rides and off-road adventures. The 750W motor gives it plenty of power, letting me hit speeds up to 28 MPH and tackle steep hills easily. The 624Wh removable battery lasts a good while and takes about 6-7 hours to charge. I love the four ride modes, from pure electric to pedal assist, so I can pick what works best for me. The fat tires and suspension make it super comfortable, even on bumpy trails. Plus, the retro design is cool, and it can handle up to 330 lbs, which is great. Overall, it’s been a fun and reliable bike for all kinds of rides.

I purchased bike to ride on local trails and i couldn’t be happier. To start, the bike is shipped in a really sturdy box. Everything was in excellent condition upon arrival. Installation was very easy. The instructions are very straightforward and I was able to completely assemble the bike in about 30 minutes. I am not particularly handy and it was easy for me. The performance is great. The range seems true and the speed is also as advertised. The bike feels like it’s going incredibly fast, but it’s really stable at top speed, which is nice when you want to get somewhere fast. I have put around 100 miles on the bike this far and everything is operating as I hoped it would. The tires are a nice thick size and they perform really well on pavement and off road. I really don’t have anything negative to say about this bike. I am over 6 feet tall and 250 pounds and it is very comfortable. The suspension is great and makes for a really comfortable ride, and it also alleviates a lot of stress on your body. Overall, I am so pleased with this purchase and I will be buying another one for my wife!

The media could not be loaded. I went on a trip recently and rode on a few different e bikes to get around the city as well as take tours. When I got back I had to have one. The standard looking bikes have seats that make your butt hurt after an hour or so of riding, so when I saw this bike with a motorcycle style seat I thought id give it a shot. My included video shows both riding the bike to see the display, as well as the exterior features such as the headlight and brake lights. The models I was riding in Europe did not have this functionality. Normally amazon asks to rate features, but that was not an option so I will rate them below. Comfort: 10/10 the seat is well padded and comfortable for rides around an hour long, there is also space for a second person if you had kids who wanted to ride the bike around. Speed: The bike has 5 levels, and the one I used previously had 9. I think 5 is a decent speed, but I wish it did have 1 or 2 more levels for when you wanted to get back up to speed quick if you have to stop for a railroad track or something on your path. Light: Breaklights are great and 10/10. The headlight I would say is a 7/10. I wish it had a high beam mode or something to get more light out of it. You can adjust the angle of it with the screw, but it could be a bit brighter to see cracks. Brakes: One thing that has been strange to comfortable with is the right side brake does the front instead of the rear, all other bikes I have been on were opposite, but the brakes are disk and work well to stop you. Suspension: This bike has both front and rear suspension. I think he rear could be a bit firmer for heavier people as it does get bouncy, but if you are under like 220lb it will be fine. The front shock is as good as other bikes I have ridden. The tires are also large so you don't have to worry in some grass about getting around. Their size also adds to the comfort. Battery: It shipped with a full battery. The battery also has a key to keep it locked on the bike. The range is about 40 miles using the pedal assistant and I have found its around half if you just use the motor and let it move you. Display: The bike has a display to show speed, power setting, light status (dims when headlight is on), and battery as well as a mileage readout. Note: The +/- controller has the power button on the bottom, the light on the left side. I did not pay attention to the manual and almost missed that. So far the bike has been excellent.

The media could not be loaded. Ridiculous!!! I purchased the bike with a discount. They sent me the bike came 5 days of original delivery date. Then the I assembled the whole bike to find out the rear tire doesn’t hold air! There is a leak in it. What a waste of time and money. Now I have to take all of it apart again to stick it in that box! Then I wanted to purchase it again cause I really wanted this bike and now the discount is gone and it’s 200$ more! Straight scam!
