I like the bike, good quality, came with a pump, glasses and a bag. The only disadvantage is the seat is a bit soft. Battery life is great, assembly easy. We already have almost 300 miles on it. Great for the price.

This bike is actually amazing. The color, the power, the build is all well thought out. This bike rides very stable. The hydraulic brake are powerful and make me feel safer now compared to my disc brakes on my old bike. I enjoy riding the bike and people are always complimenting me. Thanks DTTZH for a well designed bike with enough speed and stopping power to satisfy my needs.

This bike is fantastic, especially for a daily commute. While it tops out around 32 mph with rider weight, I'm 170pound btw, it easily beats car traffic and handles a 45^\circ incline at a steady 17 mph. It’s easy to assemble, looks high-quality, and cops don't bother you. For casual riding, the 1500W or 2000W models are fine—but if you're commuting, absolutely get the 4000W version. It’s worth every penny, and their customer service islike really excellent. The only complain I can think of is that thier gps screen is a little bit off,it's like 5mph off which isn't that bad tbh. I honestly would recommend it because even tho I got into a car crash, the bike was still working fine until some tried to steal it and broke my throttle.

Ordered to f6 pros. Got the order early which was awesome. For 750ish dollars the bike rips. Its very impressive compared to other bikes. No issues and everything works as it should. Easy to put together. Instructions are a little vague but I had zero issues.

So when I got this bike started putting it together when I put the light on I realized oh crap The front wheel is not aligned with the front forks so I have to adjust the handlebar to make it aligned with the wheel therefore the headlight is off to the left Not facing the way it should So I have to move the light up to the handlebars so it faces the right way not to mention the front wheel is wobbling now after riding it for a while and I tried to get a replacement part but FedEx kind of screwed me over tried scheduling it for pickup on their app and website and stuff That wouldn't work cuz they have so many issues and then as soon as I tried calling customer support to get that fixed even after I change the address and they wouldn't try shipping it to the new address they would not let me get it for pickup cuz they said it's already getting sent back to the shipper and now that shipper the people that this bike is from is charging me for that shipping Great now at this point I just want to get a refund and get something else because this is not worth it there have been other people that have reported this issue and this is a big safety hazard.

I bought the DTTZH F6S fat-tire e-bike about a week ago and have already put solid miles on it around Martinsburg, WV. Overall, the bike works very well and has been a game-changer for practical transportation. Pros: Strong motor with good hill-climbing ability. It handles most of the hills here without much issue. The bigger/steep hills do slow it down a bit (especially with my weight), but it still gets up them better than I expected for the price. Fat tires give excellent stability and comfort on roads, sidewalks, and light trails. Very helpful for people who need reliable transportation. — it makes a real difference in their independence. Smooth throttle and pedal assist. Easy to ride and fun once you get used to the size and weight. Cons: Battery life is shorter than the advertised 80 miles in real-world mixed riding with hills and heavier riders (I’m getting around 30 miles per charge when pedaling hard). The display/battery gauge isn’t very accurate — it can show full when it’s not. Would definitely recommend this bike if you need something affordable, powerful, and capable for daily commuting or helping others get around. Great value for the money. I’m already planning to add a rear basket and possibly look at the F6 Pro for even better hill performance.
