Perfect Commuter Bike! I’ve had this electric bike for several weeks , and I absolutely love it. It’s the perfect size for my lifestyle—compact enough to fit in my studio apartment and easy to store in my office at work. I started using it to commute because Ubering twice a day was getting too expensive, and this bike has been a total game-changer. I love having the option to pedal when I want some exercise, but the motor is a lifesaver when I’m in a hurry or just too tired to pedal. It’s quick, sturdy, and reliable. If you’re looking for an affordable, space-friendly, and efficient way to get around the city, this is it!

This U4 is the perfect size for me. We bought a U5 for husband. Very sturdy EBikes and easy to handle. Been riding them around the neighborhood and local burger joints. Our grandson really liked them so we bought him a U5 Pro Isinwheel for Christmas. Long battery life and very easy to maneuver. All 3 EBikes were very easy to put together. I would highly recommend these Isinwheel e-bikes.

This is an awesome bike. Easy to assemble & operate. The price is unbelievable. And very convenient. Folds up just right & fits in the trunk of my car. I am contemplating buying another. Because you can actually fit 2 of them in thr trunk.

Front brake broke off on 2nd or 3rd ride on a hill. My daughter who was riding down a hill is only a little over a hundred pounds and crashed because of this faulty equipment. We had followed the directions as provided to a the letter to assemble the bike. When reaching out to their customer service, you have to go back and forth via email and it takes them 2-3 days to respond, only to ask for more video and picture proof of issue, instead of trying to solve the problem in one shot. BIG HASSLE!!! Bike should be fun but overall a hassle and unsure about its safety, or if it was just a fluke.

The Isinwheel U4 feels like a vacation on two wheels. It's a simple pleasure. It was simple to put together. It's simple to operate (I barely had to read the user's manual). I can say more but I will get on with my review. I purchased this for my wife. I wanted something that was sturdy and had some decent power, but not intimidating. It also had to look cool. This bike fits the bill perfectly. I put the bike together in less than 20 minutes. The battery had a decent amount of juice, so I didn't charge it fully before taking the test ride. I'm 6' 2" , 220 lbs. We live on a hilly street. I was able to zip up and down the streets fairly easily. I did have to use PAS but for the most part the ride was smooth and quiet.After the test drive, I took my wife and bike over to a local park for her test ride. How did the ride go? She was thrilled. She marveled at the bike's smoothness and quietness. She learned how to use the controls very quickly. The only problem that was noted was a front brake squeal. I adjusted the brake without any problems. The bike is very solid and heavier than expected. Nevertheless, I consider this a good purchase. Buy this bike. For it's price, it is a solid value!

Bikes work really well. They have plenty of power and the battery's last a long time. We don't even use power level 3, power level 2 is plenty fast for us , plus we like the "power assist" and doing some of the pedaling ourselves. Power level 3 would be faster than I could pedal. The assembly was easy, took my wife and I about 1/2 hr.. The only complaint I have is that the users manual is a little sketchy, and we had to figure out some of the functions thru trial and error. All up though it's a good bike for a really good deal 👍
