Fiido D4S Review The BEST eBike of 2020 for the PRICE!

00:00 - Intro & specs

05:55 - Ride test & rough roads
06:57 - Climbing with power assist
07:32 - Emergency braking test at full speed
08:14 - Regenerative braking? And range
09:13 - Thoughts with Pros & Cons

*How to unlock the 25km/h limit. Hold down the e-throttle to 100%, while holding the front plus rear brakes, and then turn it on. Keep them pressed holding it for 5-6 seconds then release. The screen should flash E 08 code will reboot and now you can hit 30-36km/h with the 250W motor. But your battery life will drop significantly and check local laws you can do over 25km...

Some thing worth testing is the ability to wheel it around after its folded, many folders can be pulled around by their seat or handle bars because otherwise they are very awkward to move..

I brought the Fiido D2 wheels at 16 inches with rear suspension which makes riding over bumpy ground with out a lot of vibrations, giving less punctures, strain on wheel forks and components. The weight is 19.5 kg = nearly 43 lbs which is too heavy unlike other folding bikes like Brompton which some people say its a heavy bike at around 28 lbs! I really peddle and just use electric power on mid throttle to have the bike do all the work and enjoy the ride taking me around 4 miles (6.4 kilometres) to and 4 miles (6.4 kilometres) back before the battery runs out.

My improvement on the Fildo (D2) wound be to make it a lot lighter, fold down a lot smaller so you can take it on a bus, coach, car, train, office and air plane by putting it in your hand luggage compartment like a Brompton bike and travel a lot further just on electric power and faster just on foot power since its 52T chain crank moves you along at snail pace

Achieved by using the Brompton vertical folding mechanism which patency has now expired to fold it up very small, the battery placed in a removable (long down) bag on the bikes front handle bars where you could store up to 4 extra batteries to travel much further and more foot power bike speed by using bigger chain cranks from 52T to 58T . The reason I brought this bike and my 1st electronic folding bike was its competitive budget price around £500 to £600, variations in models eg 3 gears or 6 gears, quality construction, looks and YouTube recommended reviews but because of the improvements needed you can see why many people buy the over price Brompton's due to folding down size, weight and speed.

Those are some really beautiful roads to ride to

Really enjoyed this review and the presentation.

Thank you for not being afraid to venture into the budget e-bike category out of your bread and butter of phones, tablets and laptops etc.

- This would be ideal if they had hydraulic brakes. I have had mechanical disc brakes in both the shimano and tektro guise and they are fantastic at stopping don't get me wrong as its still brake pad on steel disc but it's not fun day in day out.

- Re-gen is not the end of the world imo, the removable battery too isn't as it can be folded nicely and brought into said home/apartment.

- I wonder if the r&d needs too much effort with the routing of hydraulic brake cable routing relative to the route of the mechanical brake cable through the frame to not kink horribly when in the folded state.

Not a knock on your review as it is fantastic, only that this style of bike and price category in my opinion should be another say £100/$100 with a good hydraulic system behind it before I whack my credit card details in.

Thanks for the effort you put in to your channel, I always thumbs up and comment when I watch as I know that helps pump the youtube algorithms.

(No?) pun intended at 2:26 “There is some *light assembly* that we do have to do: We have a *reflector* right here!"

I enjoyed that point of view camera work! Its been awhile since I rode a bike an this really was fun to watch. Thanks :)

I found Ur the best reviews person of this bike

[nikolnolastname]

Just ordered mine. I can't wait for it to come!

[exodiatheforbiddenone]

Thank you so much for the review. Was a bit hesitant about buying this because it's cheap and claimed to do 80km, whereas lots of ebikes in that price range only do "up to 20km". Great to know that it has at least 60km in it which is way more than enough for my 16km daily commute with some steep hills 👍👍

I bought the d2s for 482 euros. Has rear suspension smaller wheels and battery 2kg heavier. The reason why these bikes don't have regen is because they are geared motors. Direct motors have regen. This is also why there is a weight limit on these for the gears inside the motor. A lot of users change the front chain ring to 58t and change to cheap 30 euro mechanical-hydraulic hybrid caliper for better breaking power and less need to adjust the alignment of the break piston.

Hi, nice review as always. I'm buying one this week but worrying about changing rear tyre. Does the D4s have a connector near the back wheel like most ebikes or have they cheaped out and not put one. Meaning you have to pull the cable through the rear axel nut all the way from the controller?

[NiuxTech]

Hopefully Fiido D5s will come with suspension! Greta video, thanks for upload!

[diabloliks]

Hend,
I have the Fiido D1 with 36v10ah (the same battery) and I got 30-35km of range in full throttle with small tires and 65kgs. Perhaps with these 20inch tires, you can get 35-40kms of range.
Great review, I love these ones about green mobility.

[robgrace]

Great video and very informative, thank you.
One question though, what sort of speeds can be achieved on the flat by pedal power alone. If you have the number of teeth on the crank set and cassette then I can work out the theoretical speeds for cadence.
Many thanks in advance.

Nice area. Lovely weather. Good review

[willemvergouwen]

Would you still recommend this bike or the D11?

[mikligardur]

I have been looking at folding Elric bikes and is considering Mate City bike and others. I really like the compact style but feel the derailleur take too much place. So I would like see bike with internal gears, with carbon belt and mid drive motor.

[babyshorts]

Very nice ..I am watching all your video

[bitheroes]

Great review, any thoughts on doing some more of the range in the future? The m1 looks rather fun.
