### 1/5 — Ne sert à rien

*2023-04-25*

Hyper mal expliqué voir pas d’explications du tout … ne reconnais pas mon vélo DYU 
Perte de temps

### 4/5 — Update

*2020-11-22*

I need a update the app don’t recognize my bike
On iOS 14

### 2/5 — Non memorizza dati

*2020-01-04*

L app funziona in parte , non memorizza password di blocco e velocita’ massima 25km/h

### 3/5 — App buona ma...

*2019-07-19*

L’app si presenta piuttosto bene e svolge il suo lavoro per quanto riguarda velocità, temperatura, distanza ma la connessione iniziale (la prima di ogni sessione) é difficoltosa e bisogna, tenendo l’app aperta, rientrare nelle impostazioni, disabilitare e riabilitare il Bluetooth e magicamente si connette alla bici. Fastidioso. 
Inoltre il Maps interno non ricorda i tragitti fatti quando ci si riconnette.

Edit (un anno dopo):
È migliorata un po’. Ora alla prima connessione si connette quasi sempre. Purtroppo rimangono ancora dei problemi di accoppiamento con il BT. Non so se sia perché manca il modulo NFC.

### 1/5 — Problems with the DYU D3

*2019-05-24*

I cant adjust speed with it. 
Startup settings doesn't work. 
Cant lock it. 
App crash when you go on Basic Information 

Please update it !!!!!!

Thanks

### 1/5 — Lower top speed

*2019-05-20, version 1.4*

Good app.  The only problem is that after the update to the new version, the top speed went down from 30kmh to 25kmh.  Thanks DYU!  Also, I’ve lost a lot of speed going uphill and the battery drains a lot faster.

*review update*
After losing the old top speed and the app administration failing to update the app on the app store, i deleted the dyu app, ran the battery down on my bike.  I did this by leaning the bike against the bed on cruise control with the lights on.  When the motor died i left it until the lights and display went dark.  I then downloaded the e-c supplies app (which is found below this review) it is exactly the same as this dyu app and when linked back to the bike, hey presto! Back to 30kmh top speed, speedier uphill and battery usage back to normal.  I hope it works for you.  I would also recommend turning off automatic updates just in case it changes the speed of the e-c app.

### 1/5 — Up to 30km/h

*2019-04-30*

The speed on this e-bike through this app used to be “up to 30km/h.”   What happened with this last update????    
Now the speed through this app will only let you choose up to 25km/h.   Why would you do this????   I had quite a few people sold on buying a this e-bike because of the convenience and most importantly the speed.    If this isn’t fixed soon I will have to go back and tell these people to look elsewhere.  Not a very happy person!!!!   Please fix this very soon!!!!
(Update version 1.4)
