I couldn't be happier with the DTTZH-FS6 (48V 25Ah, 2000W). From the moment I put it together, it exceeded my expectations. The motor is incredibly powerful, with plenty of torque for steep hills and quick acceleration, while still feeling smooth and controlled. The 48V 25Ah battery provides impressive range, and I can ride for hours without worrying about running out of power. It was very easy and straight forward to put together and for the price, it's hard to find another e-bike with this level of performance and battery capacity. If you're looking for a powerful, reliable, and enjoyable e-bike, I highly recommend the DTTZH-FS6. It is also a very high quality bike made from high carbon steel and will last a very long time. Definitely a 5-star purchase!

I’ve really enjoyed my DTTZH F6S e-bike. The bike feels well-built, sturdy, and high quality, and it has been a lot of fun to ride. It handles well, has plenty of power, and overall I’m very happy with the quality for the price. My only disappointment is the top speed. The bike does not seem to go as fast as advertised. The fastest I’ve ever reached was around 40 mph going down a very large hill, and on flat ground it usually tops out at about 35 mph. That was pretty upsetting because speed was one of the main reasons I chose this model. Even with that issue, I still think the F6S is a great bike and deserves five stars for its build quality, power, appearance, and overall riding experience. I just wish the advertised speed was more accurate.

F6S - Middle Tier Electric Bike Purchased: May 12, 2026 Used: 2 Months Issues: Minor (Squeeky, Brake Chirp) I got this Bike as a Birthday Present the F6S (Middle Tier) EBike. Comes with everything as described, 2000W Peak Motor at 1000W Regular (Speed Vary on Battery Charge) with a 1200WH Battery. Have been using it at Default Settings (20 MPH / 19.7 MPH) as described, as well as unlocked speeds. It runs, and is perfect for a middle tier ebike usage for long range tours, commutes, or sporting. Important to note that Battery Life is limited to the usage of the speed you have used, so make sure to moderate your peak speed during full charge and lower it once you reach 40% to prolonge the life of the battery and motor usage. I didn't take a basket but probably should have as an additional accessory. It is definitely worth the money to actually get this type of bike for the usage that I am using it for. It looks sleek, small, compact, and fits pretty much anywhere like any regular bike. This is an Electric Bike, this is basically a motorcycle without gas, doesn't matter if this is for a child, or an adult. You need to understand the responsiblity of using these. I care for it well, make sure to clean it regularly if you go in water, dirt, and other dirty dips. It isn't just a toy, and I know many want to treat it that, don't. The issues? So, two issues that seem to be fixable with not much effort. Squeeky noises, these can come from the suspensions or the wheels, just lubricate with the correct type. The brakes also get squeeky, so make sure to lubricate as well. Other than that no issue.

Got the F6S. Arrived just as advertised. Well built however suspension squeaks a bit but that can be easily fixed. Im 6'0 and 215lbs and I got it up to 37mph on a straight road and 40mph going down hill. Im considering getting the PRO because I want the 40mph lol.im thinking the pro would get up to 47mph and 50 on a downhill. Looks, weight, feel, and height is very comfortable for a guy my size. After research, it was between this bike and the Coswheel gt20. I believe either choice would be a great choice.

I was extremely satisfied with the results and smoothness of the bike. Easy to set up and i really recommend watching the tutorial on their site then using the instructions before opening the box. Very good deal for the money and the battery life is good to me. Bike is a lot bigger in person and it’s very sturdy. I absolutely recommend getting this e-bike when getting into these, or as a collection bike for cruising. Very comfortable
