All that I was hoping for and more !

I've been looking for an e-bike that can carry people, has plenty of power, and has dual suspension. This e-bike has all of that and more! Don't compare it to a regular bike, because it's not. It takes cycling to a whole new level.
The KINGBULL Voyager was well packaged and arrived without any damage. It took me over an hour to unpack and assemble. It came with all the tools and instructions. The battery was about 70% charged so I was able to test the Libra immediately. I checked over all the cables and connections and made sure all the nuts and bolts were tight.
Even though the Voyager is slightly heavier than other e-bikes, I had no problem starting to pedal without PAS. Once I enabled PAS, the fun began. It was cool to ride in 95 degree Fahrenheit weather and maintain an average speed of around 15 mph without much effort. In PAS 3 mode, I can easily reach speeds of 20-22mph.
My daughter has found her new favorite. I got the backrest and pedals and added rear seat handles. She feels safe and says it's a comfortable ride.
I asked kingbull some questions and got a response within 24 hours. I would say that I can easily rate this ebike a 5 out of 5. It has very good build quality and the battery can be charged for a long time. The tail light is easy to see and gets brighter when braking.

Best Ebike for DoorDash delivery

I love my voyager! I use it to deliver DoorDash loads and zip around downtown Denver with no problems at all. The two batteries really make a difference for me because I can stay out longer, make more deliveries, make more money, and then recharge the batteries. Charging time for both batteries is a little over 6 hours, which is pretty quick. I weigh slightly over 230 lbs and the bike holds my weight well and is very sturdy. I've put about 300 miles on this bike since May of this year and it has been running great with no problems. Very responsive with a top speed of about 25-30 mph. The bike is perfect for my job and my ratings have improved due to the quickness of getting to delivery destinations. I get a lot of compliments due to the frame and overall construction. The customer service team was great as well. They were helpful and courteous. I highly recommend this excellent e-bike.

I love everything about this bike. It fits me well, I weigh 250 lbs and am 5'9". It came well packaged and was easy to put together. It is a very sturdy bike, and they probably went overboard making it so sturdy, but I'm not complaining. When they said it could hold up to 440 pounds, I believed them. The tail light comes on when you use the brakes. The display is large and easy to read. The bike stops well, much better than my other bike that uses mechanical brakes. The electric motor is very powerful, up to 28 hp when I ride it. It also rides smoothly and pulls me up hills with ease. The thumb throttle works better than the quarter twist grip. The pedals gripped solidly on my shoes and weren't the kind that screw up. The grips feel good and are easy to grip on long rides.
One last question...
It's not a disadvantage, but if you like to use the cup holders on the frame, you'll need to reconsider as there are no holes.
Please feel free to buy it, you get what you pay for.

Great Step Thru Bike

We were looking for bikes to use when we go camping plus to use around the house. Our thought was it's way cheaper than other brands and you can use a bike anywhere you go where. I was looking for a bike that my wife could ride since she's 5'2". Saw this bike and after reading the reviews I thought that I would give it a try. The price was in our wheel house as first time ebike owners. The bike came well packaged and about 50% complete. Took minimal effort to put together. Watched a youtube video on how to install, but the manual was very clear.

Great bike.

I bought my father this bike without the basket on the back. It turned out to be a really nice bike so I ended up buying this one for myself. I now have the perfect bike I need to make the local trips up to my grocery store and other small errands. It's got a great range of speed and is comfortable to ride. Since buying it I've recommended it to everybody.
