All I had to do was put together the handle bar, bike pedal, front headlight, front mud flap, and attach the front wheel because the bike arrived 85 percent prebuilt out of the box. Bike pedals are simply screwed on and tightened using the wrench provided. To tighten the level of the headlights, use the provided allen wrench and philip head to screw in the front headlamp and mud flap. All of the gear is mounted to the handle bar; all you have to do now is place the collar into the bike column. Installing the front wheel was simple: tighten the nuts on the detached wheel, remove the anchor nut from the bike, insert the front wheel, secure the quick release, and the wheel should rotate freely.A small adjustment to the disk break is required. The bike was only half charged when it arrived, so you'll need to fully charge it before using it. The key insert is located on the side of the battery cannister so that it does not obstruct operation. The key can be turned on, but the bike does not need to be turned on if you just want to ride it like a regular bike. However, if you turn on the power button and begin pedaling, the bike will assist you in maintaining that speed without using the throttle. The bike's top speed is 20 mph, and the battery can run up to 30 kilometers on a single charge. That's more than I'd need to get around my town on a daily basis.I can carry the bike up and down my porch to go on a ride around town because it is only 50 pounds. The bike's weight capacity is 330 pounds, which means it can carry a lot of weight for such a small bike. It's up to you whether you want to charge the battery or not. This bike is fantastic and is the finest way to go about town; highly recommended!I can ride it very comfortably without feeling awkward at all as if it was a bike designed for someone my height. The seat and handle bar goes down far enough where I can stand comfortably. I must say that at first I noticed my pedaling seemed fit right. I do not have to bend my knees way too much, and I thought perhaps it’s because the pedals have a bigger adult diameter. I either simply put the seat height up a little so that I have to stand on my tip toes now while on the seat and now my knees look pretty normal while peddling. It felt like a normal bike to me, no compromise in how it feels geometrically as a bike for me. I have to give the credit when it due that they accomplished this versatility really well. It is powerful. I live on a hill and it easily brings by 180 pound body up the hill. I can control it normal, but it is so powerful that I have to be careful while on it. I think my body does not put enough weight stress on the bike so that it takes off like a rocket. I just want to extra careful the first few times so that I am aware of its power and get used to it. If not, I can easily see how an accident might happen. This is especially true with the pedal assist. When they pedal even a little to go slowly, if the pedal assist it is on then it explodes them forward like a rocket. I solve this by having the power on when I first start on the bike. It can run about 10 to 15 mph depending if it’s riding. It is also an extremely light electric bike. For the price, I paid for it with happiness.
