Color: Black 1500W 48V 18.9Ah Single Motor
The bike was very very easy to put together. You only have to put together the handle bars in the front wheel for our money. I feel like we got a very good quality bike my husband ride it back-and-forth to work. He rides it about 10 to 20 miles a day back-and-forth to work it gets in there. The battery is very good. It doesn’t die or start to lose battery. Very easy. This is just a perfect bike for a long commute and he said it’s very comfortable. ... show more

  • Awesome Electric Dirt Bike 🏍️
Color: Black 1500W 48V 18.9Ah Single Motor
The media could not be loaded. Holy Cow! What an amazing bike! 🏍️ FX20 1500W I purchased this bike because there were really good reviews on customer support from a this vendor and I agree 100%! Before the product ships the vendor will reach out to confirm you want to purchase and provide you with additional information. I’m a 5’5” woman, I would say I’m strong, but not super human. This bike has some real weight to it, so be prepared to use your legs if you will have to lift it for any reason. Quality materials, this is real steel not plastic so it definitely adds to the weight. The matte black finish on the paint gives it such a classic look! Easy to assemble and sooo much fun to ride! The screen display is very helpful and easy to navigate. I was able to get up to 35mph and I have not unlocked the bike. I’ll need to ride around the neighborhood and do more off roading before I consider that option. The battery life seems pretty good, but I haven’t rode it from full battery to low yet. Excellent value for the low rate, and I can see how it will be great for off roading. Good shock support. It can fit in the back of my 4 door Jeep Wrangler without issue. ... show more

  • Do NOT PURCHASE-plastic, garbage electric
Color: Black 1500W 48V 18.9Ah Single Motor
Have had this bike for a little over a month-maybe 2 months. Now there’s an electrical connection that’s just shot. The connection from the power switch to the motor by the rear wheel has 3 prongs and one has somehow been fully pushed into itself and another is partially pushed into itself, which means it’s not connecting to the female side. This is a covered connection so how does this occur?? Now there’s just an Ereor message. So basically the bike is useless. This hasn’t been ridden like crazy, just around the neighborhood. Also, the pedal broke after like 3 weeks. The plastic just broke off. We keep it out of the elements. The front bumper is flimsy and bends and rubs on the front wheel so now the bumper is ragged and worn down. Don’t buy it. Plastic garbage. No wonder they say no returns. ... show more
