Fiido D11 Review: Key features, Pros and Cons of E-bike in 2022


Before starting the review of the Fiido D11 eBike, an important and necessary clarification must be made. The electric bike comes equipped with an accelerator complete with cruise control. This means that, with current regulations, it cannot legally circulate on the roads. Fortunately, there is a quick and easy way to make it legal. In fact, the throttle cable can be disconnected by deactivating this control. To be even safer, if you want you can also cut it without any problem and it is an operation within anyone’s reach.

In this way, the Fiido D11 becomes a normal pedal assisted bike and can circulate safely on the roads. At this point we start with the review.

Fiido D11: Design and Ergonomics

Pedal assisted folding bikes are especially appreciated for their ease of use in urban environments. They are not two wheels to travel tens of kilometers at a time but are just fine to move easily to go to work, with the advantage that they can then be easily folded to be stored in the trunk of a car or parked in a small box.

In recent weeks I have tested the Fiido D11, an interesting model in many respects since on paper it promises a lot, including an almost “record” battery life for the category, that is up to 100 km. I have to be honest, despite Fiido being a well-known brand on the market, I had doubts about the quality of the product but in the end I had to change my mind about some things. Not everything is perfect and there are several things that can be improved but in the aspect I was most afraid of, the assistance, at least in my case, Fiido did a good job. But we’ll talk about this later.

The eBike arrives almost completely assembled. What you will have to do is take it out of the box, insert the seat and mount the pedals. The package also includes a mini manual, the power supply, an adapter for English plugs and some always useful tools. Once extracted, it really takes 10 minutes to make it ready for use. One detail should be noted: the battery is integrated into the seat post tube and to connect it to the engine, the rear spiral cable must be inserted into the appropriate socket. Let’s see the main specifications.

To all this is added that in front there is an LED light that can be activated by a special command on the handlebar (there is also an electric bell). Behind, on the other hand, there is an LED that always stays on when the power to the bike is started. On the handlebar, on the other hand, the display providing the main usage indications is located on the left side.

Being a folding eBike I was very curious to try the system designed by Fiido which uses a mechanism on the frame that should allow you to quickly open and close. It actually works well and allows you to fold the bike in a matter of seconds. To facilitate the process also the hook that allows you to bend the steering tube in a few moments. The whole system seems robust but only with time will it be possible to understand if there really will never be problems. It’s just a pity that the pedals can’t bend. There is no system that holds the bike together once folded: you will have to equip yourself with some amateur solution if you plan to transport it for important routes.

If the need is to load the folded bike in the car, the suggestion is to remove the saddle with its tube that contains the battery to remove several kilos and thus make the maneuver easier.

Fiido D11: Impression

Ok, so far the eBike specs, but how does the Fiido D11 really look in your hands? As said, I was a bit wary but compared to other products in this “made in China” category, the step forward is evident.

Aesthetically, the Fiido D11 is pretty, thanks above all to the particular shape of the frame and the blue color. The bike appears well assembled (the welds of the frame are however a little too visible in some points) even if some constructive choices could be revised. For example, there are a little too many cables in front and also quite “exposed”: they suggest that they can get entangled somewhere, perhaps when you park your bike in the crowded racks. Fortunately, these same cables are then routed inside the frame and disappear from view. Nothing serious, especially considering the type of bike and the price range.

The bike also has, as mentioned before, a small display that allows you to view speed, battery charge status, assistance level and distance (but only from the last start). Very simple, it reads fairly well as long as there is no strong ambient light. Now let’s talk about the element that characterizes the eBike and that is the seat post tube with the integrated battery. A particular choice that has pros and cons. The main advantage is that the tube can be easily removed and then taken home or to the office to recharge the accumulator. As already mentioned above, it can be easily removed to make transporting the bike by car easier.

On the other hand, in case of theft or damage, the cost of the replacement will obviously be very high since the eBike battery is inside the seat post tube. Furthermore, there are two problems that must be reported, the first of which required assistance from the assistance.

Fiido D11: Assistance

Before we see how the Fiido D11 really goes, let’s talk about assistance for a moment. When I received the bike I immediately took a test ride, just a few kilometers to see how it went on the road. Well, after about 5-6 km I heard a noticeable crack. I stopped but didn’t notice anything about the gearbox, brakes, chassis or engine. The manufacturer declares that this model carries up to 120 kg. I am not light, about 100 kg x 183 cm, and therefore given the specifications I did not expect any particular sealing problems.

On the way back, I put the bike in the box and I found the “problem”. The seat tube had “opened” a few millimeters. The tube, in fact, is not a single piece and at the height of the junction between the two pieces of which it is composed it had opened slightly. This did not please me at all and it made me fear for the quality of the product. After contacting the assistance (a couple of emails were needed), I was guaranteed that a new piece without the defect would arrive without any problem.

Meanwhile, I was told that the bike could be used without any problems. To all this it should be added that on the D11 website there are two notes that speak of this problem.

This is a defect known to the manufacturer and related to one of the very first batches of bikes. All those who run into it can safely request the replacement of the defective tube. People often talk badly about the assistance of this kind of product but in this case, despite the “distance”, everything went well.

Fiido D11: Driving

Adjusting the seat height is no problem. The manufacturer has also included a graduated scale with a minimum and a maximum. The strange thing is that the minimum level indicated is fine for a person of 180 cm in height. Theoretically, this would leave shorter people out. Fortunately, the seat can be positioned lower. The head tube, on the other hand, cannot be adjusted in height.

However, finding a good position in the saddle is not difficult at all. To “start the bike” it is necessary to carry out two operations. The first is to turn on the power by pressing the button on the seat post and the second is to turn on the display on the handlebar. 3 are the levels of assistance provided. The first assists up to about 10 Km/h, the second up to 15 Km/h and the third up to 25 Km/h. The maximum speed is reached only by insisting a little with the pedaling. The best cruising speed with Level 3 is 21km/h when you have maximum support. Pedaling with the engine off is not very convenient since it offers a good resistance.

The suggestion is to always use assistance level 3 and an intermediate report. The Fiido D11 exhibits good agility on the road. It is a foldable eBike, this must always be remembered, but it must be admitted that it is handled well. The engine offers decent thrust and is also a bit noisy but once you reach cruising speed you can pedal easily. Personally I have covered about twenty kilometers in a row keeping the 21 Km/h constant in all fluency.

If you have to tackle very short climbs, no problem as long as they are not demanding. The Fiido D11 is a bike for flat roads, not hilly ones. Nothing to say about the change, precise and fast. Also good are the disc brakes that work well in classic city situations as long as you don’t jump down steep descents where they struggle a bit. Small criticism for the tires. In curves, especially if they are fast, they don’t offer a great feeling but nothing serious. Negative note on comfort if you have to deal with long stretches on rough roads.

The absence of a front shock absorber is felt a lot in these contexts. And here is the second problem of the saddle, even if not serious. The seatpost tube tends to go down a little while pedaling, especially if you are tackling somewhat bumpy paths. A nuisance that forces you to reposition it at the right height after some time. It can be solved by working on the screw of the closing hook and perhaps adding a small thickness.

But how much autonomy does the bike really have? Not 100 km as stated, at least in my case. It is known that with eBikes the maximum distance depends on many factors including the route, the weight of the cyclist and the level of assistance used. Starting with the battery charged, I traveled about 70 km using assistance level 3. Not bad anyway.

Fiido D11: Conclusion and Price

I got along well with the Fiido D11. Aside from the seat tube issue, the bike performed well. Indeed, I would add that it has always been pleasant to ride. It is not an eBike to run with but for its target use it is more than adequate. Let’s talk about the price for a moment. On Aliexpress the bike currently costs $999. Surely there are some interesting technical solutions that are worth a price increase compared to the other Fiido models but for a non-Premium folding one, exceeding the $1,000 threshold is too much.

For those interested in buying it with our coupon it is possible to have it at a price of $650 euros, a cost certainly more appropriate to the contents of the product.


Pros of Fiido D11:

  • Autonomy
  • Easy to fold
  • Shimano gearbox
  • Design
  • Weight

Cons of Fiido D11:

  • Some construction details that can be improved
  • The seat tends to go down with use
  • Engine a little noisy
  • Comfort on the bumpy
