VIVI 20" x 4.0 Fat Tire Folding Electric Bike for Adults

Amazon Customer: Well built, easy to assemble. A very bad lag in the throttle, very annoying. Also very short for an adult. There should be more distance between the seat and handle bars. Had to buy a different seat that would slide more rearward.

Martin Funke: Also die Qualität des Fahrrads ist ok aber nicht gut… Schaltung muss regelmäßig eingestellt werden (alle 2 Wochen), Bremsen zu schwach,Akkulaufzeit ca 25km bei voller Unterstützung und bei Mittlerer ca 35km.
Wenn ihr nur kurze Strecken fahren wollt ist dieses Fahrrad passend für euch aber alles was weiter weg gehen soll kann man vergessen…

Wi: The media could not be loaded.  This bike creaks like it is an old mattress. The pedal assist is not continuously working. I have to pedal half the time without pedal assist working. I want to return this bike. It is not comfortable and does not work as it is supposed too...also the phone number for customer support does NOT work.. good luck getting help. I have not received anything back to my request of this bike being defective and needing to return it. This manufacturer has not done what it has promised. No parts sent and NO PARTIAL REFUND. VERY UPSET WITH AMAZON.....
I finally got my part, HOWEVER, I have yet to see my refund and Amazon did not five me their A to Z guarantee that is was supposed to be taken care of within 48 hours....

M. Trimboli: Love the style the ride is easy to handle. Goes fast so I use the low or med with petal assist. The only thing is it does not have a speedometer like the more expensive ones. So we will add one from Amazon.

CuteAsADaisy: My 17 year old bought this to give him more time to save up for a car... he's been really enjoying using this as a way to get to work and has gotten a lot of comments on how nice it looks. I rode the bike too and it has nice pick up and was a ton of fun to ride. I'm 5'1" and it worked well for my small frame but adjust to fit larger people too - most of the other ebikes I have looked at start at 5'4" height suggestions. He's taken it back and forth to work a few times and still haven't had to charge it (3.5 miles trip each way). We bought some folding pedals to make it more compact when folded up and are very happy with the purchase.

Privat: Das Fahrrad an sich ist ganz ok leicht aufzubauen aber! Artikel kam schon mit Lackschäden an und teil defekten das Rad zerkratz sich selber da der Lenkrad griff den Lack am Lenkrad abnutzt Akku hält leider vielleicht Max 25 km (Unterstützung s) Modus und die Kette fängt an an irgendwas zu ratschen ich hätte das bike trotzdem behalten wenn das mit der Kette nicht wäre da ich sonst sehr zufrieden war bis auf die kleinen Punkte macht echt Spaß aber leider nicht so gut verarbeitet
Update:
ich möchte den Artikel zurück schicken doch dies erscheint als sehr schwierig deswegen gut überlegen ob man den artikel wirklich bestellt da man in ohne Kopfschmerzen nicht zurück geben ich muss jetzt viele Transportdienstleister anschreiben und schauen wer mir das günstiger Angebot macht und Ichs dann nach China schicken kann und die Retouren kosten werden auch erstmal ! selbst gezahlt

Harold: 1.) Pedaling is only useful in low power setting. Higher power settings resulting in faster speed - one can not pedal as fast. Therefore
I installed a 58 tooth front pedal gear and now the gearing is OK. Needs 6 more chain links for the bigger wheel.

2.) The throttle is so sensitive that most of the time one starts with full throttle.
This can be dangerous. Have contacted the seller but to no avail.
3.) Yes it is heavy for the size.
I will only use it during camping.
4.) Best of all they have working support and this helped a lot.

R G Stark: Quite heavy, but fine once you use it. I found the pedals are quite difficult to fit also . However, got in touch with the seller about the pedals, so all is fine now. Good bike.

Mr. S. PaxmanMr. S. Paxman: Bought these bikes to carry in our camper van to explore when we are out and about. They fit great when folded, but they are quite heavy. Very easy to put together and everything fits as it should, barely referred to the instructions, if you have messed with ordinary bikes this is no different. Not really used in anger yet, but took for a spin around the block and it does make riding a breeze, plenty of assistance when needed and very responsive. all in all very pleased.

Marina: Sono molto soddisfatta dell acquisto. Non sono una ciclista provetta, ma la bici Vivi è divertente e arriva ovunque. Già con l assistenza low permette di affrontare salite discrete . Ottimo l aiuto con il medium e con l high la spinta è davvero notevole. Ottima per le commissioni e le piccole spese. Apprezzata anche da mio marito e lui si se ne intende.
Attenzione alla prima pedalata ...la spinta potrebbe sorprendervi.
La ricarica permette ottime percorrenze : testati 40 km con utilizzo di assistenza media.
