DYU FF500 20 Inch Fat Tire Electric Bike

So I've had my Ff500 for while now and I have to say I would easily recommend this ebike to anyone , now why though ? so let's get down to the specs we'll start with the nice 180mm brake disc's that provide a great stopping power I'm 175lbs n there's no issue of stopping with the bike. Now let's talk power 🔋 you will do 20mph in 3rd electric gearing up before you know it the throttle is smooth an not Jerky like some e bikes out there. the 20x4.0 tires are a nice solid grip to the pavement or if you want to head on the trails or dirt and with the suspension fork n seat you can't go wrong. now don't let the ff500 kid you saying its a commuter ebike because it can be upgraded I pushed that creative envelope and still going. this bike will support up to 300lbs with ease no issue. the lcd is a M5 with a rear hub drive motor n I love how the battery is integrated into the frame of the easy point of locking and unlocking with a key. an weighing around 60-70 ]
pounds around that it's very easy to pick up and fold up an be on your way to your next destination.

Love the unit, should come with a back light. Also wish it could be unlocked to class 3, 28 mph. Lastly would like to know how to purchase a spare battery.

Do not hesitate to buy this bike! I have been a mechanical engineer for over 36 years & have wrenched many assemblies through all of them. Quality you can see and feel as soon as you look inside the box - best packaging I have seen yet, ensures that your bike is not damaged in transit. It has hydraulic disc brakes (most have mechanical), trust me hydraulic brakes are a must have for a bike of this weight & size, it actually skids those huge fat tires when you need to stop fast! The battery seems to last forever (especially in the lower assist modes). In pedal assist mode (5) I was able to hit 31 mph (just to see how fast it would go) with me pedalling in addition to the motor (it will go 21 if you do not pedal - power only). This bike is powerful & strong!! I am a big guy - 235lb gym rat and I am very comfortable on this bike. In my opinion you will have a very difficult time finding a better bike at this price point - most bang for your buck. I almost never write product reviews, but I would encourage others to experience the same enjoyment that I have on this bike.

The bike is large and heavy.The battery life is really good.

As others have commented more thoroughly, this is a beast of a bike. It rides like butter in its various power assist modes, but I can still peddle as much as I want without freewheeling by shifting gears. The battery lasts and lasts, and the torque sensor is very smooth. I really like the step-through model -- I'm 5'10 and have always ridden a regular mens road bike, but given the weight of the bike and my being in my 50's now, it's sooo much easier to have a step through design.

Just as importantly, the company was excellent in answering some of my newbie questions.

The only two issues I have are related to the style of bike, not any fault of this bike. First, it really is heavy. It's definitely easier to have a second person around to help get this in and out of car, or even on a bike rack. Second, sometimes I'm in a situation where I want to walk next to the bike to wheel it somewhere without turning it off--- if I step on a peddle to help move it along, it's very likely it will jump forward as the motor kicks in. Not a big issue but something that caught me off guard a couple of times.

So I spent a *lot* of time looking. but couldn't find a better combination of features on an other bike in this price range. eg, the Aventon bikes have torque sensors, but not fat tires, other bikes have similar specs but without the torque sensor, others don't have a step through model, etc. This bike was the right choice for me given what I was looking for.
