  • Amazing Ebike and superb Customer service.
Color: White Style: Standard
Hello everyone. I hope this help you guys First of all this it’s an amazing bike and its price it’s Amazing. You will not get anything with this build quality and certifications. I received my bike well packed and no visible damage. However the back light was broken and the battery had some issues. They customer service it’s superb and this it’s what I want to stress to you all. I purchase about 5 e-bikes/scooter. 2 from isinwheel. By far isinwheel has the best aftermarket support. All the other bikes you will be on your own trust me. They also went above and beyond to make sure I was satisfied. If your bike has any issues just wait and reach out, they will fix it for you. Shipping something this heavy has consequences, it’s not their fault , those that worked in logistics knows. As a community we should show appreciation for business that do things right. Share, review, comment. They deserve it. I am a client for life. And I can’t wait for my current Ebike to died so I can upgrade to the isinwheel u8 cargo Thanks Tammy and Lesley. You guys are very kind. Chris and Jenifer ... show more

I love my little U4 ebike. Took 2 hours to assemble. Works well. I have about 500 miles on it now.

  • Love the bike.
Color: White Style: With Rear Basket
We love our bikes. The baskets are definitely nice to have to carry stuff. Having foldable bikes make them so easy to use while out RV’ing. So much better than the standard bikes. Easy to ride, easy to fold, easy to transport. They fit perfectly in the back of our Jeep Wrangler. Gave 4 stars for a couple reasons. They are heavy to lift. The piece that holds the handle bars in place loosen up while riding. The piece that you release to fold the bike has stripped after folding it 3 times on one of the bikes. We would and have still recommend these bikes. ... show more

  • Impossible to safely and properly assemble
Color: White Style: Classic
Shame for not giving clear assembly instructions. There was nothing that addressed getting the front wheel to align and fit with the brake. The video is prob AI and conflicts with the assembly brochure. Really disappointed I bought this. I can’t even ride it!!

  • Love our e bikes
I love my bike! So easy to assemble. We did get a different seat for my husband’s bike. Very easy to switch out. They sent a fender asap after we noticed mine didn’t have one. Custer service was AWESOME! 5 stars
