The Ultimate STEALTH eBike!! (Fiido C21 Review) 

Thanks for your review and greetings from Italy to you

Great video and nice ebike!! Have a good day and week.

Good e-bike, good video!

Great video, can you answer me, ⏩⏩ it is in charging mode when you pedaling? Can you charge bike when pedaling in OFF mode?

Could you in future test the ride on steep or longer hills. Where I live in LA I have short very steep hills plus the best roads just a couple miles away are about 5 percent grade for a couple miles, so I mainly want the ebike in order to survive hills for errands and recreation. I saw a Soltera2 ebike review that very helpfully showed that with barely pedalling or just sitting using basically only pedal assist on a very steep hill the bike went only 2 or 3 mph and ground to a halt in a couple minutes, but constantly pedalling kind of hard with max pedal assist made it up a mile long very steep hill holding 7 or 8 mph, that kind of info is very helpful especially if someone could say how hard or athletically they had to pedal to maintain that 7 or 8 mph (which that reviewer did not say, by the way)

Do you know if the handlebars can be raised?

Good day, I received my Fiido C21 Pro today, unboxing and assembly was completed with the help of the Fiido video. the fenders were a little trickly and fiddly. Just 2 questions. 1. can you tell me if there is a way to check my C21 frame is medium or large, it feels large as I can only just stand up straddling the crossbar, the order stated clearly M. 2. When using the cycle for the first time I was expecting to see assist levels 0,1,2,3,4,5. But see eco, normal, sport, turbo, turbo+ and rocket modes, has this replaced the assist modes that I saw when looking at various videos on youtube including yours which was one reason why I chose this e-bike.

Well done on missing the iron gate ...:-)

Nice video, any problems with the bike yet?

This is great. And first comment 😎

Thanks for a very informative review, but how could you tell us that the chain ring "looks like" 62 or maybe 54 55. You made your point, that it is a relatively big chainring, but how could you not bother to check the specs or count the teeth if you had to? i realize many riders especially riders who did not spend time riding conventional bikes (good for them anyway for e-biking) don't care. but a lot of us want to ride the ebike mostly under our own power for some flat non-windy parts of the ride, and the chainring teeth numbers will tell us a lot about whether we will be able to. I ride my conventional mountain bike on the 30 or 40 teeth chainring, but if you put a 55 teeth chainring on it I would quickly grind to a halt. So ebikes that commonly come with a 40 or 42 tooth chainring might be just the gearing I want, while 55 teeth might be way off. Sorry if my being quite ignorant about ebikes ( I AM trying to learn more) makes my comment make no sense.

How to remove the battery from that bike in case of faillure in the battery?

Can you try to fit trek DS3 (gen5) tires on a new model FX3? If they do fit, I want a DS tire set for my FX3. Please let me know

I have this and there's no way you're getting 25 miles at the highest assist level. I barely get 15 miles at level assist 2. The battery is the biggest let down on an otherwise great little bike. The motor is vg. However, I've read that mivice are making a 360wh slim battery that can fit into the down tube, thus creating its own e-system since mivice already make the wonderful torque sensor motor.

Don’t fool people… this bike sucks. I have one and makes noises all over, wheels are really bad, 1 euro pedals, and battery extender is a joke
