D3F is really worth buying for the price that it is. If your looking for something exciting , small, comfortable, powerful motor, fast , and is easy to assemble in under 5mins. I say it can go about 20 - 25 mph. I weight about 165 and it’s no problem. I still feel the fast speed it puts out like 20 plus mph like nothing. I even hike my 4 yr old son who bout 45-50 lbs , and still goes fast. Very good motor. I use it for just cruising around my neighborhood everyday just to enjoy the outside . I really recommend this bike if you love speed and power . You’ll be Satisfied for what you’ve paid for .
