    • Great E-Bike for a Person Over 60.

Review Image by Franklin Garza
I'd been wanting to get an electric bicycle that didn't cost a lot of money, didn't take up a lot of space, and was easy to ride. This DYU D3F exceeded my expectations. I have 2 recumbent trikes but this is my favorite vehicle to ride. It was easy to assemble. It's not heavy. It's simple. It goes as fast as I need(I'll be 65 soon.). I added a used bike rack that was on a trek bicycle and mounted it to the seat stem. This allows me to carry snacks, water, sunscreen and mosquito repellent. I weigh about 160 pounds and the DYU is rated for 265 so it has plenty of power to haul me and my gear...:) I like that I can ride it like a regular bicycle without electric power and give my legs a workout...:) If you want a simple, inexpensive, electric bicycle, I don't think there's many better choices than this one. I did a lot of research before I bought it and this is one of the best purchases I've made. It's a very handy vehicle to have...:) ... show more

    • An Adult Fun Bike
Color: Black
I can't believe how well-made this bicycle actually is. It's very robust and can carry a rider that weighs up to 264.5 pounds and 6 feed 2 inches in height. This bike is small, but it's heavy at 42 lbs. Compare that to a $10k+ road bike that weighs 14.9 pound, and you get an idea how heavy the DYU D3F really is. After I installed the fender, seatpost & saddle, tightened the handlebars, installed the pedals and the flashing brake light, I was impressed with the design. Everything works. It's in perfect condition and it was packaged to make sure nothing gets damaged during shipment. The power assist is different, as there's only one level, and it's perfect, because you will never have a hard time pedaling. I wish the power assist was the same in my 26" ev bike....no power assist level to fiddle around with! However hard you pedal, it will match you, so you don't have to strain. The cruise control is engaged by throttling on for 8 seconds and it will stay at the speed you had the throttle going at. If you brake or accelerate, the cruise control will turn off. If you don't want power assist, turn off the power. There is no key to lose, as the power is activated via the button on the left handgrip. One of the reasons why I bought this bike is so that I can carry it in the trunk of my car, instead of a bike rack or roof rack. I'm not a cycling fanatic, but I enjoy riding my bike and I don't need to prove anything to anyone. And I don't need to go fast. 15 miles per hour is enough for a bike this small. Lastly, this is way better, more comfortable and more stable than an electric scooter. This is basically an electric scooter with a seat and pedals and it works extremely well. ... show more

    • Really good entry point bike!
Color: Black
Who knew you can order an ebike on amazon and get something of good quality. After doing some research I found this ebike for my son and ordered it. It is just as advertised rtized and I'd order it again. It was easy to assemble and great value for the price. I recommended it.

    • Awesome little bike for commuters
Color: Black
This little bike is a beast. I mean I had my doubts as the wheels are tiny and frame is small. I am a road bike rider and this is the complete opposite of those. Carrying a road bike onto a train or car is not that practical. This thing is small and has a handle. So much easier. The power is decent though I most used it manual mode. I prefer to peddle but I must admit using the motor to assist on hills is nice. Not much to complain about, though because of the weight and shape, the front lifts up when trying to peddle hard on hills. It takes some getting used to. I also wish the battery lasted longer. But for the price this is prob the best you can get. ... show more
