La qualità dei componenti e del montaggio è pessima. Di seguito i problemi riscontrati:
1) Disco dei freni leggermente storto, tocca anche un po' vicino le pastiglie
2) Parafango posteriore storto e impossibile montarlo perchè il supporto si sovrappone leggermente al cambio nella zona della vite, il foro quindi non è allineato ed il parafango tocca sulla ruota.
3) Dopo aver smontato il coperchio del controller è impossibile rimettere le viti, filettatura fatta male.
4) Il fermo della batteria è leggermente più piccolo del foro, il che provoca movimento e rumore di ferraglia durante la marcia
5) Fusibile rotto dopo 30 km, il che potrebbe significare problemi di corrente (tra l'altro durante la carica, il caricabatterie diventa incadescente)
6) La batteria non dura nemmeno la metà di quanto dichiarato
Mille euro (in sconto) è un prezzo esagerato, dovrebbe costare almeno 300, 400 euro in meno per la qualità offerta. Se non fosse per le dimensioni del pacco e per le politiche di reso l'avrei già mandata indietro
7) I raggi delle ruote non sono in tensione, c'è bisogno di portarla in assistenza per farli stringere perchè fanno rumore e potrebbero danneggiare la ruota.
8) Accessori del gift pack non ancora ricevuti dopo 20 giorni

My experience with the DRVetion BT-20
My experience with the DRVetion BT-20
-ENG-
On the website, the bike is advertised as 250W, unlockable to 1000W. Unfortunately, this is completely inaccurate, as the power cannot be limited, instead only the speed can. Furthermore, the bike is equipped with a throttle and arrives with it mounted and activated.
The bike is NOT LEGAL in ITALY.
I decided to keep the bike anyway, limiting the speed and disabling the throttle. It's also possible to remove the throttle entirely, but the bike remains ILLEGAL as the motor exceeds 250W.
On the other hand, it's not common practice for the police to stop an e-bike for checks. Problems arise in the event of an accident.
Unfortunately, I found the bike's display to be completely UNREADABLE in bright light. You don't need to be in direct sunlight, just plain daylight. From any angle, the display, set to maximum brightness, is almost always completely unreadable.
Convinced it was faulty, I contacted customer service and sent them two videos clearly showing the display being unreadable. They refused to cooperate. Eventually, they told me I could buy a new screen.
Now there are only two possibilities.
- The first is that they're selling a bike with an unreadable display, and this is unacceptable because using the display is essential when using an e-bike, just think of the level of assistance.
- The second is that customer service refuses to offer after-sales support, and this is even more unacceptable for a product like this.
The bike also has another problem: if it goes up a hill, the battery level drops dramatically by 20-30%. I imagine this is due to the 1000W power, which can't be reduced even when this possibility is advertised.
I also admit that the bike is solid and well-made, but given the problems I encountered, I can't recommend it.
-ITA-
Sul sito la bici è pubblicizzata come 250W sbloccabile a 1000W. Purtroppo questa indicazione è del tutto inesatta in quanto non può essere limitata la potenza ma invece solo la velocità. Inoltre la bici è dotata di acceleratore e arriva con quest'ultimo montato e attivato.
In ITALIA la bici NON E' LEGALE.
Ho deciso di tenere lo stesso la bici limitando la velocità e disattivando l'acceleratore. E' anche possibile rimuovere del tutto l'acceleratore ma la bici resta ILLEGALE in quanto il motore è di potenza superiore a 250W.
D'altro canto non è pratica usuale, da parte della polizia, fermare una ebike per controlli. I problemi nascono in caso di incidente.
Purtroppo ho riscontrato che il display della bici è completamente ILLEGGIBILE se c'è luce. Non serve essere sotto la luce diretta del sole in controluce, basta che ci sia la luce del giorno e da qualunque angolazione il display, impostato alla sua massima luminosità, è quasi sempre del tutto illeggibile.
Convinto che fosse guasto ho scritto al servizio clienti a cui ho inviato ben due video dove si evince chiaramente che il display è illeggibile e si sono rifiutati di collaborare. Alla fine mi hanno detto che posso comprare un nuovo schermo.
Ora le possibilità sono solo due.
- La prima è che vendono una bici con un display illeggibile e questo è inaccettabile perché l'uso del display è fondamentale durante l'uso di una ebike, basta pensare al livello di assistenza.
- La seconda è che il servizio clienti nega l'assistenza post vendita e questo è ancora più inaccettabile per un prodotto del genere.
La bici ha anche un altro problema: se affronta una salita il livello della batteria cala drasticamente del 20-30% e immagino che questo sia dovuto alla potenza di 1000W che non è riducibile quando però è pubblicizzata diversamente.
Ammetto anche che la bici è solida e ben realizzata ma alla luce dei problemi riscontrati non posso consigliarne l'acquisto.

Hello,
This is DRVETION E-BIKE.
We sincerely thank you for sharing your detailed experience with the BT20. We deeply apologize for the issues you encountered with the bike. We take your feedback very seriously and would like to provide a transparent explanation regarding each point raised:
1. Regarding motor power and throttle settings
The BT20’s maximum speed is factory-limited to 25 km/h, which corresponds to a motor power output of 250W; therefore, adjusting the speed effectively adjusts the motor power.
The throttle is typically activated at the factory for performance testing purposes, but we provide a way to disable it should you wish to do so.
2. Visibility issues with the display screen
If the screen is difficult to read, the brightness setting may be too low; please try adjusting the brightness. The display is covered by our 6-month official warranty. If your screen is within the warranty period, we will send you a brand-new replacement free of charge and cover all shipping costs—you will not have to pay for the part or delivery.
3. Sudden drop in battery level when climbing hills
A temporary drop in battery level of 20%–30% on steep inclines is a normal physical characteristic of lithium batteries under high instantaneous current output; it is not a battery malfunction. When the motor outputs peak power during a climb, the battery voltage drops temporarily, causing the displayed battery percentage to plummet. Once you return to flat ground and power demand decreases, the reading returns to normal. To mitigate this voltage drop, you can lower the pedal-assist level while climbing to limit peak current.
We appreciate your positive comments regarding the durability and build quality of the BT20 frame; however, we sincerely apologize that the issues with various functions and service aspects resulted in a poor overall experience.
If you have any further questions or need assistance, please feel free to contact me at
[email protected].
Best regards,
DRVETION Official Customer Service Team

Our bicycles are all manufactured using high-quality components, so you don't need to worry about malfunctions during normal riding.
If you have any questions about our bicycles or need assistance, please feel free to contact me at [email protected].

Advertising on Facebook shows fatbike…
Advertising on Facebook shows fatbike with acceleration handle, so you don't have to peddle, which is fine for a moped, but not when selling as a bicycle. Their website only has a support number from CHINA, so if EU customers have problems, they can only get help calling a Chinese telephone number. No mention of a physical address anywhere. Reeks of SCAM!
