Vivi Electric Bike for Adults 1000W Peak Folding Electric Mountain Bike 26'' Commuter Ebike 22MPH Adult Electric Bicycles with Battery, LCD Display, Dual Shock Absorber, SGS Certified to UL2849

We bought two of these bikes for my husband and I to ride around the neighborhood or take while we're camping. The shipment was excellent as they arrived earlier than expected (shipment was from NJ or somewhere in the NE) and the boxes were intact with no damage. Husband assembled both bikes and said, for the most part, the instructions were pretty clear and he was able to figure out the confusing parts.The bike is sturdy and heavy, around 60 lbs. It's foldable and folds at the frame, but the handle and pedals don't fold and the bike is still bulky and heavy when trying to insert the folded bike into the cargo area of a hatchback car. We ended up having a hitch installed on one of our cars and purchasing a sturdy bike rack (from Amazon) that would carry at least 120 lbs. in order to transport these bikes whenever we wanted to take them to the greenways in our city.The battery is large and heavy, but there is a bag that carries it at the handlebar so it's easily removable to bring the battery into the house to charge it. There are 2 cords leading out of the battery, one to charge it and another to connect it to the bike. You have to thread the connection cord through the small hole at the bottom of the bag in order to connect it to the bike wiring, and that is a bit of a headache to work it through the hole.The controller to activate the pedal assist works pretty well while cycling. It activates within 2 seconds of holding down the on/off switch and you can feel it kick in to propel you forward. I usually turn it off when I am going through tight spaces like a small, narrow bridge or lane to stay in control of the bike, but definitely use the pedal assist feature on incline and hills. We have hilly terrain in our subdivision and some streets require me to use the medium setting to get to the top of the hill, and it does it quite easily. The low setting is usually enough for me to get around. I haven't needed to use the high setting because so far the med setting gets me up the steeper streets. There is a throttle on the right side of the handlebar that allows you to use the pedal assist feature continuously without pedaling but I haven't needed to use it often. I definitely love the pedal assist feature to get up those hilly streets!We had to switch the seats to wider seats because the one that comes with the bike is very narrow and uncomfortable. We also got sturdier and louder bells as the one that came with the bike is lousy and has a puny sound. We added bottle holders easily to the bike frame since there were 2 screws for that purpose already on the frame. I do wish they would have included mirrors to help when we're maneuvering and turning on the street. That's something else we'll have to buy. Also, there is no speedometer but I found an app for my phone to help monitor my speed and distance.The fenders are kind of flimsy but they work. At my height of 5'3", the height of the bike is okay and I can easily stand on the balls of my feet when the bike is stopped, but I end up hitting and kicking the back fender regularly when getting on the bike, and I have to straighten it up.We're really happy with these bikes and so far haven't had any major issues (knock on wood.) We especially love the lower cost for this electric bike and that it looks good, works very well, and has a year warranty.

I've owned this bike for a couple of year's now, so I'm comfortable giving it a review.It's a low end big box store type mountain bike that has been adapted into an e-bike, and that's not a bad thing. It was easy to assemble, showed up in good time and in good condition. It was decently packed. It folds easily, the frame is sturdy and when it's locked there is no play where it locks. It's heavy, but it's a folding bike so it's made from steel, the welds are good by the way. It has suspension front and rear, it rattles and there are no adjustments, but it works ok and I'm 6'2" 200 lbs so it's good enough, rattles or no. I had to replace the seat, but the included seat was serviceable, just not comfortable for me. It's reasonably powerful and climbs the hills around here well enough, but it needs some help on the steeper hills. The battery hanging off of the handlebars is heavy, so it can make handling a bit heavy, but it's ok once you're used to it. The tires are surprisingly good although I had to true the wheels with a spoke wrench. I'm a Mechanic, so it wasn't hard, but it isn't, just follow the instructions on any good YouTube video and that will walk you through it, this is not unique to this bike, having to true spoked wheels on bikes is a common maintenance item. I bought the bike because it was a mountain bike design, it was inexpensive and had good reviews. I didn't know anything about e-bike's when I bought it, but I've learned over the year's to look at things like this as a learning experience. Nothing teaches like hands on, and I didn't want to spend much money on something that I knew nothing about, so I did as much online research as I could and took the plunge, thinking that whatever happened I'd know enough after a couple of year's to buy a "real" e-bike. I wound up liking this bike, sure, I will eventually buy a better one now that I know better what to look for and what I need, but this bike is good enough for my needs and will be for several more year's, so it's money well spent. I know way more now, about e-bike's in general and what specific bike I want to wind up with (that will be a cruiser/commuter with a 48v, 750 watt motor, at least a 1000 watt peak, over 75 Nm torque and somewhere around a 10 amp hour battery that's removable and frame mounted, 7 as opposed to the 21 speeds the Vivi has, 27.5" wheels, and an adjustable and lockable front suspension, (a rear suspension isn't necessary for me), and 3" hybrid tread tires. The two caveats are, or were, the handlebar mounted battery, which proved to be a better and more protected setup than I thought, although it does make handling a bit heavy, but again, it's ok once you're used to it. The other thing is that there is no mention of a BMS (battery management system). A BMS does a number of positive things to the battery, and most importantly, protects it from overcharging/overheating, but since I can't find any information about whether it has one or not, I behave as though it doesn't and I'm careful when I recharge it, never leaving it alone and making sure to check periodically to see that it doesn't get too hot (it never has, it only gets a little warm when charging, which is good) and I *never* overcharge it. Once the light's on the 2A charger turn green, I take it off the charger. This is easy to time estimate once you've charged it a couple of times, so I see it as safe as long as I keep an eye on it and unplug it once it's done. It has never given me any trouble because of this, in addition, the battery itself is UL certified so as long as you don't leave it plugged in for hours after it's done, it should give several year's of good service. Would I recommend it? Yes, I'd share the information I shared here and if you're on a budget or need a $400 education about e-bike's and also want a solid commuter and to get some exercise while getting outdoors, then it's not a bad choice.

1st Review: The bike itself functions fine.However the charger was bad upon arrival.Never did get a working charger with it.Fortunately I have another Ebike that uses this charger.However I still need one for THIS bike!The charger I paid for with the bike will suffice.If you don't have an extra charger, this bike will be worthless once you run the battery down.They answered my questions, yet never sent a new charger.They asked me to make a video of a charger that does Nothing. So the video will show, guess what? Nothing!Then Amazon says the video is too big so I text the video to myself to make it smaller.Now Amazon won't accept the video Format!The whole process seems designed to prevent you from getting a reasonable replacement.Am happy with the bike and am happy that nothing else is wrong, because it is extremely unlikely you will get it working with the very poor support.Will revise if they decide to take care of their customer.2nd review:5 stars. Vivi contacted me afterwards , & agreed to send me a new charger.They followed through as promised!Am happy with the bike & now the service. : )
