Kenkupka: The media could not be loaded.  I bought a Vivi electric bike a few months ago and I couldn’t be happier with my purchase. It’s the perfect bike for commuting, exploring, and having fun. The bike is well-designed, easy to use, and very reliable. It has a powerful motor that gives me a smooth and comfortable ride on any terrain. The battery lasts for a long time and charges quickly. The bike also has great features like front suspension, disc brakes. The bike is very sturdy and durable, and it looks awesome too. I get compliments on it all the time.Vivi folding 750 watt model fits my needs. They also shipped the bike fast and securely, and it was easy to assemble.
I highly recommend Vivi electric bikes to anyone who is looking for a high-quality, affordable, and fun e-bike. They are the best in the market, and they will make you fall in love with cycling again.

guruguru: I did not expect the bike to reach the advertised range of 50 miles. The most I have achieved on low power assist mode is 30 miles. It is too early to judge the battery life, but I have not noticed any degradation after one month of use.
This bike is heavy and difficult to keep vertical when folded, as the wheels keep moving. Watch out for bruises on your legs due to metal parts hitting your skin. Description says it is Aluminum frame but the heavy weight does not align with advertisement.
The disk brakes are okay, but not much different from traditional rubber brakes. After assembly, it requires a lot of time to adjust the spokes and the disk brakes, as they tend to rub against the rim and make a hissing sound. This drains the battery while using power assist due to unnecessary friction.
Adjusting the disk brakes proves to be a challenging task, regardless of the number of instructional videos available on internet. If taken to a bike shop, expect to pay around $80 to fix this issue. The ride is comfortable thanks to the dual shock absorbers, especially if you change the seat to a more comfortable one.
Throttle does not work if you are paddling in low and medium power...

Amazon Kunde: The E-bike works very good and moves so fast,But they have to work on the battery aspect because it doesn’t last long the way i expected it to… But am still in love with the e-bike and can refer someone to go for it as well…..

RaminGRaminG: This bike has excellent value and good quality. It has adequate range for 20-40minute workouts on hilly roads by this older adult. The pedal assist and throttle are a joy to use and along with judicious shifting, the ride up steep slopes are comfortable. The steel frame makes it a bit heavy but sturdy. It can fold comfortably in the back of most vehicles.
Packing: Cardboard box held up well to shipping but had one small hole and small tears. All the contents were well protected.
Assembly: Using both the paper manual and the online assembly video, assembly took several hours with no issues. Supplied tools were adequate but some steps needed two allan keys or wrenches. Most of the time was spent tightening and inspecting. Front wheel bearing was a bit stiff and needed oiling. The chain at pedal hub needed to be pulled onto pedal sprocket. Front Brake lever had too little play resulting in grabbiness; needed to increase cable length slightly.
Charging: Initial charging took about three hours. The 48V battery pack consists of 13x3 2600mAh 18650 LiPO cells in a sealed plastic box. There is a small power switch on the cable end which needs to be turned on to provide power....

Pier Luigi VivanPier Luigi Vivan: Ottimo prodotto anche se il montaggio non è semplicissimo. Quando sono riuscito a montarla non funzionava e grazie al suggerimento di un’amica ho aperto la centralina e mi sono accorto che un cavetto non era stato collegato. A parte questo inconveniente la bici è ottima su strada e sterrato. In salita offre il giusto aiuto e le caratteristiche rientrano nei canoni della legge italiana visto che non si può circolare con ebike che superano i 250 w di motore e che superano i 25 k/h con pedalata assistita. Inoltre l’acceleratore viene inviato ma non è montato perché in Italia non si può circolare con ebike che hanno l’acceleratore. Tutte le altre ebike con diverse caratteristiche sono illegali e quindi si rischia una grossa multa e il sequestro della bici. La consiglio.

Dx: YouTube Video über das Produkt suchen und so aufbauen, wie gezeigt.
Nicht sehr kompliziert.
Der Akku ist mickrig, Hersteller bietet keinen Ersatzakku an.
Das ist sehr schlecht. Der recht kleine Akku ist nach 30 km leer. Ein zweiter Akku könnte mitgenommen und sehr schnell getauscht werden .
Gibt es aber nicht.

Wenn der kleine Akku mal kaputt geht, kann man das Fahrrad wegwerfen. Ohne Motor ist es zu schwer (fast 30 Kg) um damit zu fahren.
Wenn man den Motor ausschaltet bremst er das Rad nicht.

Der Sattel ist viel zu niedrig, habe für 29 € eine gefederte Sattelstütze 35cm gekauft. Man benötigt aber eine Hülse, das Loch im Rad hat 28,6 mm, die Sattelstütze 27,2mm, man braucht eine Adapter Hülse 27,2 - 28,6 mm. Gibt es für 11 Euro hier bei Amazon. Hält dann sehr fest.

Der leere Akku benötigt knapp 5 Stunden zum voll aufladen.

Die Griffe die ab Werk drauf sind muß man mit einem Messer aufschneiden um sie zu entfernen und die beiliegenden Griffe zu montieren. Die sind sehr bequem und man hat dann einen Gasgriff.
Das Rad ist geradeaus recht schnell, leicht berghoch schafft es der Motor kaum noch.
Der Motor reagiert sehr...
