    • This size tire not sold in the US but otherwise extremely solid choice
Loved this bike, I have used it for a year before I got a nail in my tire. I asked every local shop and no one could replace the 3x20 tube tire, I plan on eventually buying a replacement tire from the vivi website itself though I am unsure how long I will have that option as this model seems to no longer be sold by this company. I also wanted a new battery but, it seems like they don't make this battery either anymore. Very solid bike -- sturdy, well built, relatively easy to put together -- does not come preassembled. Can handle light sand, normal levels of gravel, to some extent can fjord an inch or so of water (I got caught in a freezing rain downpour here in northern michigan once that was a crazy ride), has significant enough power to handle my steep hilled roads in my lakeview town. These roads are labled with warnings for trucks. Though it does come at a steep battery cost. It wasn't a bother though as I took my charger everywhere. Full charge got me around 20 miles a day and I pushed the limit to 22 easily, even with some hills. Difficult to pedal without assist, but with assist a breeze that will not leave you sore (I believe just because it is a rather heavy bike). I would note that you should always leave this bike covered with charging, as the charger is also not water proof -- and I am not sure how much longer this charger type will sell on their website either. It is a lithum ion charger too, three pin type like you can find for scooters and wheelchairs (tho the lithium ion is not universal -- some have lead batteries and the company warns you that you should use the charger that comes with this for this bike). I am a really short person and it JUST fits my height. I am five foot exactly of a feminine build. ... show more

    • NO regrets after one year.
My first e-bike is not bad at all, considering the low price. I had no issues putting it together, As Vivi advertised, it is rather on a slow side, about 22mph, battery charge about 30-35 miles. Had a small issue with front brake, but customer service was very responsive and sent me a new brake assembly. I wish this bike could clear steep grades, therefore 4 stars. ... show more

    • The Vivi MT20UL review
Color: D-Black Size: Compact (20 inch wheel)
The Vivi MT20UL review confirms that it meets the stated specifications. Initial acceleration is excellent, and it starts smoothly. The tested top speed is approximately 22 mph. It feels sturdy and durable, and is comfortable to sit on.

    • Great bike for great price.
Have been on the hunt for a ln electric bike. Did not want to spend more than $600 for my first one. After months of research and debate. I found this was the best suited for me. Foldable, 22mph (got some power) with decent range. Sleek looking. Worth every penny. Great starter e bike. Fair price. Well made. Very Easy to assemble. I am 5’11, 220lbs and I would say someone 6’5 could ride it no problem Only negative and this is not picking, it is pretty heavy. ... show more

    • Trrottle might not work.
I paid less than $500 before sales tax, ($200 shipping of that amount), so pretty good price. Ride is ok, bike seems to have more power than "Electric" brand which I also own. Throttle does not always work, some days does, others it does not, so I'm thinking it will probably quit completely after a few hundred more miles, (currently about 240 miles on OD. Fairly good buy at this price. ... show more
