After 10 seconds of inactivity, the fingerprint switch light will automatically switch to battery indicator:
Green Light: High battery (Above 60%)
Blue Light: Medium battery (40%–60%)

Fiido Air ebike

I received my Fiido Air for my 80th birthday and I am generally pleased with it. It is easy to ride and comfortable but I have a problem with charging. I am never sure if it is fully charged and so I’m not sure how far I can go. It takes some time to get it to start as it doesn’t go easily from blue to green. I wear the watch but am not sure what it does as it usually just shows the time. It seems to be a matter of luck whether I can get it to start or not.
Can you send me an instruction manual please?

Dear rider,

First of all, we would like to wish you a very happy belated 80th birthday! It makes us truly happy to know that you are enjoying your Fiido Air and that it brings you comfort and ease when riding.

Regarding the charging, please don’t worry. You can usually tell if the battery is fully charged by looking at the light on the charger — when it changes from red to green, it means the battery is full.

For the use of the bike and the smartwatch, our support team will be more than happy to assist you. They can provide you with a detailed manual or even step-by-step video guides to make things easier. Please feel free to contact us anytime at support@fiido.com.

Thank you again for your trust in Fiido. We wish you many more joyful rides and pleasant moments with your bike!

With our warmest regards,
— The Fiido Team

My first electrical bicycle

The Fiido arrived at my home inside a carton box. Half an hour later everithyng was in place for the first experimental raid. Smoth, silent and confortable. Beautifully designed, simple, robust, they say and I believe. After the first more than 200 Kms in the Fiido Air all I can assure is my complete readiness for the daily raids in the coming years with the training of the last thirty years doing it in an “analogical” bicycle. The Fiido Air is something!

Great bike

It won’t win any races but great for just getting out on the road and exercising. I only use the battery to get me home again and for larger hills.

Fiido Air

Bought mine from a local bike shop. It is nice and fast to use on level roads, hard to pedal on uphill because of its single speed setup.

Dear Biker,

Thank you for your feedback on the Fiido Air! 😄 We're thrilled that you find it fast and practical on flat roads. The single-speed design can indeed be challenging when climbing, especially on steeper trails. If you'd like tips for a more comfortable ride or information on possible adjustments, please contact our support team at support@fiido.com. We'd be happy to help you so you can have fun wherever you go! ‍♂️

Wie erwartet sehr gut verarbeitet. Klar muss man sich kurz mit der Uhr und der Konfig beschäftigen, war aber auch kein Hexenwerk. Fährt top und ist wirklich leicht :-) Kann ich nur weiter empfehlen. Für die Standard Touren im Stadtgebiet, zu den Naherholungsgebieten, oder wie bei mir, als Begleiter auf dem Boot, einfach sensationell. Würde nicht damit durch die Alpen fahren, aber das ist auch nicht der Sinn und Zweck.
