    • Easy to use, fun e-bike.
My first time to buy an ebike. It is so easy to get on /off. I have been riding it around shoreline and around the city. It is so reliable and can go a long long way with 1 charge. Speed is pretty decent. The cost is good, the frame is of high quality. Love it. Highly recommended. Very sturdy and easy to assemble. ... show more

    • Good moped
Front brake a bit sticky which locks down the motor, have to make sure brakes are fully disengaged. Otherwise works fantastic. Daily commutes go well. Works well for a bigger dude with no cargo. Pedaling is a bit difficult due to leg length (5" 9 tall) but I didn't get it to manually pedal. Plenty of charge for 3 mile commute 6 days a week throttle only. Have had a flat since running over stickers, but there was only 1 actual hole after like 10 of them hit the wheel so I'd say par for the course for tire + tube thickness. Get some slime and prefill the tubes or buy pre slimed tubes to save that headache. ... show more

    • Powerful and fun ride – perfect for commuting and off-road
I’ve been using this 1500W electric bike for a few weeks now, and I’m honestly impressed with its performance and power. The motor is very strong and provides quick acceleration, especially when going uphill. It feels stable and smooth even at higher speeds.

    • Defective parts, seller does not handle after-sales service, not recommended.
Review Image by bt
There was a screw hole on the frame with no threads, so the screw couldn't be installed. The seller initially told the buyer to find a repair shop to fix it, then promised to send a replacement frame. Ultimately, there was no follow-up.

    • Great, comfortable ebike
Review Image by D. Campbell
I've had this bike a little over two weeks at this point. Overall, I enjoy the bike and highly recommend. A few minor pre-assembly errors out of the box that my husband was able to correct. The brake line was routed incorrectly and still needs to be fixed but doesn't effect the bikes performance. More of a visual annoyance. All that aside, I still give the bike 5 stars. I've made a couple of small modifications for my personal comfort and I Love it. ... show more

Poor made product. Had an issue with the screen out the box. Look for more reliable options. I wouldn’t recommend. And good luck trying to rerun it.

Looks nice. Seems to be running great. Instructions were not great, and it was rather hard to build.
