easy assembly and great quality. Bought it for my son when he leaves to college, so I test rode it and it was amazing! I weigh 240lbs and it was going 23mph with no pedaling!

At 79 years old, this is the perfect touring bike, especially the assisted pedaling feature and the cruise control your new ebike introduces to. Great buy. And...it works well pulling a cart.

It has worked well for me so far, but I do feel a little sketched out by the brakes sometimes. The mechanical brake calipers leave some to be desired, even when adjusted fully out there is a very small gap that the disc has to fit though, combined with the fact that the wheels aren't entirely spinning true causes the discs to rub a lot if you don't have the brakes adjusted all the way open. This results in mediocre and uneven braking performance. It is manageable, you just have to think ahead if you really want to go flying down the road on this thing. It wouldn't be much of an issue on a regular bike but at higher speeds it is less than ideal. Other than the above, the build quality is great for the price point, and the battery life is acceptable for what it is. Assembly was pretty easy. I like the built-in headlight. Didn't have an issue with the directions personally, you get a full color manual with pictures along with the instructions. Some poor english sometimes but you can figure it out with context clues. Where this bike excels is keeping the pedal assist set to "low" and just letting it help you accelerate from a stop or climb hills without having to shift down as often. On low, the assistance turns off at like 5mph or so allowing you to cruise under your own power and keep your battery going longer. There is somewhat of a delay before the assistance turns on and off when you stop/start pedaling, making it feel a little poorly controlled at low speeds on "high" setting. I recommend leaving it on a lower setting if you need to start and stop frequently where you ride. All considered, this is probably the best e-bike you are going to find in this price range and even with the sub-optimal brakes I still recommend this bike and feel safe using it.

The media could not be loaded. Can't beat the price for this bike. So far so good, some of the parts could be better quality especially the tires but overall pedals great with motor assist or has good power to get you around. Yes you can spend 3-15 for a top of the line e-bike but thats just ridiculous. Save the money on expert assembly, took about an hour or so to put together if you have any kind of mechanical skill. Manuel is horrible but there are some good vids on youtube for this bike. Its not that hard to figure out.

This seller is from China hiding behind a NJ shipping address, they are impossible to deal with! RUN burn your money it is more satisfying, read on Unfortunately for me or anyone that purchases this bike the description is completely inaccurate! This bike has a 17" frame and 27.5" tires, it is universally accepted that a bike with this size frame is designed for riders that are a minimum of 5'10 and taller. I went to a local bike shop and they explained these characteristics to me and that the description of a 17" frame is not acceptable for the height ranges they described. The description says men 5'4, Im 5'6 and I can not stand over the bike without being on my tip toes and I still am uncomfortably touching on the bar, their description saying that 5'4 can straddle this bike couldnt be further from accurate, this is clearly why they say the bikes can not be returned. Overall it is well made and worth the money, but DO NOT BUY THIS BIKE UNLESS YOU ARE A MINIMUM OF 5'10 OR TALLER REGARDLESS OF YOUR SEX BECAUSE YOU WILL NOT BE ABLE TO COMFORTABLY RIDE THIS BIKE AS THEY ARE DESIGNED TO COMFORTABLY FIT YOU, THIS IS A SAD REVALATION AS i AM DISABLED AND PURCHASED THIS BIKE TO REHAB MYSELF AND IT IS A USELESS WASTE OF MY MONEY. The description is completely inaccurate except for the part that it is non returnable

Easy to assemble and use. Works great, helps me do my shopping, and riding against the wind is much easier. I like that I am still providing power by pedaling

The media could not be loaded. The bike is nice, but you get what you pay for it’s made of a lot of plastic. It has plastic over the wheel wells which bends very easy. It looks nice it rides nice but like I said it has a lot of plastic parts so you get what you pay for like I said and for my husband who will probably never ride it it was OK.
