  • A Vacation On Two Wheels!!!
Color: Black Style: Standard
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! ... show more

  • Fun and great to get around.
Color: Black Style: Standard
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. ... show more

This is a well built e bike that has long range and easy to charge and store. it is not hard to assemble (two person 15 min). So far, we had it for 2 months, and used it many times, it has performed flawlessly. We really enjoyed the rides. Go get it!

  • Great for kids not ready for bigger powerful bike
Color: Black Style: Standard
Very sturdy and will put together bike. We added a bag for the rear rack and a bottle holder. My son has so much fun with this and gets great exercise. No problems going on 20 mile rides as far as battery. I wish there was more pedal assist speed levels. Acceleration is smooth and manageable for anybody. ... show more

  • GREAT E-BIKE
Color: Black Style: Standard
I love it ! Fast enough for cruising around town and the battery last a long time I’ve made several trips and just now had to recharge the battery. My husband and I saw a E bike at Costco that went 20 mph didn’t have the battery life as this one it and it was $999 so this is quite the bargain.. I had been looking for one and had browse through quite a few of them and I’m glad I picked this one. He won’t go wrong. ... show more
