- A: AnswerYou can press for 2 seconds the (-) and (+) from your controller and it will take you to the settings of the bike. Then keep pressing the middle bottom on the controller to get to next screen. You will find the option to increase mph to 45 km. Once changed, select de middle bottom from your controller and it will allow you to reach 28 mph using pedal assist. If you use the throttle it will reach up to 20mph only.

Amazing Ebike for Daily Commutes!
I've been using the GoTrax Z4 Pro Foldable Ebike for my daily commute, and it’s been fantastic. Here’s my experience: Quick and Easy Setup: Installing this bike was a breeze. I only had to adjust the brakes a bit, but there are plenty of how-to videos on YouTube if you need help. Comfortable Ride: The ride is smooth and comfortable. I use it to commute to work, which is about 10 miles away. Google Maps estimated it would take 1 hour and 10 minutes by bike, but I consistently make the trip in 40-45 minutes, even without using the pedal assist. I mostly rely on the throttle and hit a max speed of 20 MPH. When I use the pedal assist, I've reached speeds up to 30 MPH. However, I find 20 MPH is perfect for city riding—fast enough to get around quickly but safe enough to brake suddenly if needed. When I get to work, I charge the battery. Reliability and Freedom: This bike is incredibly reliable. It gives me the freedom to go wherever I need without depending on public transportation. Plus, I save on vehicle insurance, tolls, and other expenses that come with owning a car or motorcycle. Pros: High top speed of 28 MPH Long range of up to 50 miles Easy to fold and store Comfortable and smooth ride Saves time and money Cons: A bit heavy when folded Overall, I love the GoTrax Z4 Pro for its reliability and convenience. I highly recommend it to anyone looking for a great ebike! Design: The foldable design is super convenient for storing in tight spaces. The black finish is sleek and modern. Battery Life: The battery life is impressive, allowing for multiple long rides. Comfort: The ride is smooth and comfortable, with adjustable handlebars and a well-padded seat. Ease of Use: Assembly was easy, and the controls are intuitive. Value: Excellent value for the features and performance it offers. Pros: High top speed Long range Convenient foldable design Stylish look Comfortable ride Cons: A bit heavy when folded Overall, I’m extremely satisfied with the GoTrax Z4 Pro. Highly recommended!

Not sure yet
Not the easiest to put together as directions are not much to go by. Make sure you put the fender on with light first. Then go for front wheel. My front rotor was scaping the brake pads. Had to readjust and finally pull the rotor out more. Customer Service isn't good and no one gets back to you till 72 hours via email. No one on phone can help either. No FAQ on website as stated in email from response. If you are under 5'2 this still will be a big bike for you. Plus handle bars don't lower for shorter people either. I had to loosen screws and tilt handles down. It take 2 people to get out of box and flip bike over to attach front wheel. Very heavy bike. It does NOT go 28 MPH. Top speed with just thumb throttle is 19. Only one sprocket for gears so you end up using the highest anyway. Other than a long set up time and help moving it, the jury is out for now. Rode 5 miles tonight to get use to.

The best purchase I’ve made in a long time !
I'm absolutely loving my new electric bike! The pedal assist feature has made my daily commute a breeze, and the battery life is impressive. The bike itself is sturdy and well-built, with a comfortable seat and smooth gears. The electric motor is quiet and powerful, making hills a thing of the past. Plus, it's great for the environment and my wallet - no more parking fees or gas money! Overall, I highly recommend this e-bike to anyone looking for a fun, convenient, and sustainable way to get around.
