Super Electric Bicycle!

This electric bicycle is one of the best purchases that I have made. I have miles of hiking and biking trails near my house and this Isinwheel D4 just eats them up. I typically ride about 5 to 6 miles each ride and the battery hardly moves off of 100% charge. It's sportier looking than most of the other bikes, goes up to 25 MPH if you dial up the speed settings and is really a hoot to ride! Isinwheel Direct shipped my bike very quickly and it was packaged extremely well. I would not hesitate to recommend this bike to others, and I would buy it again!

Long battery life

These E bikes are great. Long battery life. Comfortable to ride. Easy assembly. Would recommend.

750 W motor and foldable, This is a fantastic commuter bike.

My work is about 5 miles away, which is just right for a good morning workout commute to work. This bike is foldable so I can easily transported or throw it in my friends trunk on the way home. The batteries are movable also so if I want to go mountain biking, I can take it off and have a lighter ride. There’s dual suspension so it works in just about any environment and has Shimano seven speed gears. the fat tires, allow me to write it next to canals and not worry about a flat. This is very comfortable and supportive and one of the better E bikes I’ve seen out there.

Great Bike

Having a 500 Watt (750-peak) motor, it's able to handle some relatively steep hills. It exceeded my expectations. I love this bike!


One of the benefits of a foldable electric bike is jtz portability and easy to storage. With its compact size, this bike can be easily stored in a small space, making it a good option for those with limited storage space. In terms of performance, it listed on the web for 750w, but it may only go up to 500w but it is still powerful enough to prove a top speed of up to 20-25mph. And the 48v 15ah removable battery offers a range of up to 60 miles on a single charge. This makes it suitable for longer rides or commuting to work or school. Overall this bike for adult appears to be a solid choice for those looking for a foldable electric bike with fat tires and front and rear suspension.

Isinwheel D4

The Isinwheel D4 e-bike is a slick design folding bike. It offers everything you want from speed, looks, easy storage, comfortable ride and long distance riding. This bike offers a good package at an affordable price. I highly recommend it for your needs of riding. It is to add all the additional accessories you want or need to make your ride more enjoyable and safer when on trails or group rides.

Excellent purchase!!

I bought it for the hubby.. he loves it!! Takes it out on his off days!

Really great bike and price.

Really great bike and price. First venture into an e-bike so didn’t want to spend $2-3k. This was under $1k and worth that price. You can find them less but the fat tires are awesome. Not everyone would want a fat tire but at least get a 12.5 amp battery or higher. You’ll be glad you did. The battery lasts a long time especially if you ride manually and only use the pedal assist when needed.

Isinwheel D4 E-Bike

The bike arrived very well pack with tons of protective foam inside the box. Very easy to assemble. Only had to adjust the front brakes but not a big deal. After charging up the battery pack, it was off and riding. Then notice that I had to slightly adjust the gears. No problem again because the bike rides very good and fast. Isinwheel bike is faster than my wife/granddaughter bike’s. This Labor Day weekend will be the real ride. Going to go trail riding and test the distance out on the battery.highly recommend buying this bike. No regrets.

Very fast

This bike beat my idea of what i expected. Very nice bike that last a long time for miles and is fast! Has a loud horn for saftey and a bright led light! A must buy!
