Day one review: 50 y/o disabled Vet. Assembly last night was straight-forward, simply follow the video and use included tools (or pull out a cordless driver and some sockets). Charged the battery over night and fired it up this morning. Immediately got Error Mssg #3, looked in the manual and found a wire that I hadn't connected. Bam, up and running. Directions, videos, and manual in American English. Started at level 1 to get the feel, very mild and comfortable, quickly worked up to #5 and ripped off down my roads. Hit 25 mph and had an absolute blast - Super Comfy. Pros: UL listed battery - Don't buy an ebike without this! Mild, not torquey, plenty fast for an old guy with multiple back injuries. Simple to use, Strong, heavy bike with soft suspension. 750 Watt motor is considered a "pedal bike" by law so can go anywhere a regular bike goes. Cons (for some of you, not me): not really a wheelie, stump jumper, burn out bike. Top speed mid-upper 20s. If that's what you need, you need to look at 1000-2000 Watt range.

Bike came with defective tire. Bike came from China. Amazon will not contact distributor to send us a tire. Says we have to call China or we can send it back. It came unassembled, it’s now assembled. Issue now resolved. Support team sent new tire within 7 days. Had local bike shop install same next day. China stayed on top of problem and are sending me a couple of phone mounts as consideration for $40.00 mounting of new tire. Support team from Windone has been great.

The media could not be loaded. I went on a trip recently and rode on a few different e bikes to get around the city as well as take tours. When I got back I had to have one. The standard looking bikes have seats that make your butt hurt after an hour or so of riding, so when I saw this bike with a motorcycle style seat I thought id give it a shot. My included video shows both riding the bike to see the display, as well as the exterior features such as the headlight and brake lights. The models I was riding in Europe did not have this functionality. Normally amazon asks to rate features, but that was not an option so I will rate them below. Comfort: 10/10 the seat is well padded and comfortable for rides around an hour long, there is also space for a second person if you had kids who wanted to ride the bike around. Speed: The bike has 5 levels, and the one I used previously had 9. I think 5 is a decent speed, but I wish it did have 1 or 2 more levels for when you wanted to get back up to speed quick if you have to stop for a railroad track or something on your path. Light: Breaklights are great and 10/10. The headlight I would say is a 7/10. I wish it had a high beam mode or something to get more light out of it. You can adjust the angle of it with the screw, but it could be a bit brighter to see cracks. Brakes: One thing that has been strange to comfortable with is the right side brake does the front instead of the rear, all other bikes I have been on were opposite, but the brakes are disk and work well to stop you. Suspension: This bike has both front and rear suspension. I think he rear could be a bit firmer for heavier people as it does get bouncy, but if you are under like 220lb it will be fine. The front shock is as good as other bikes I have ridden. The tires are also large so you don't have to worry in some grass about getting around. Their size also adds to the comfort. Battery: It shipped with a full battery. The battery also has a key to keep it locked on the bike. The range is about 40 miles using the pedal assistant and I have found its around half if you just use the motor and let it move you. Display: The bike has a display to show speed, power setting, light status (dims when headlight is on), and battery as well as a mileage readout. Note: The +/- controller has the power button on the bottom, the light on the left side. I did not pay attention to the manual and almost missed that. So far the bike has been excellent.

Had the bike for 4 days and already having issues with the battery, rode my bike to work went to leave and it didn’t turn on so I assumed maybe the battery died even though I charged it fully the night prior I came home put the charger on and the light was green indicating it’s fully charged but still won’t turn the bike on.

I bought this bike for my son back in December 2024. We had the bike for about 2 weeks when things started falling apart . . The assemble was easy and was working fine until 12/28/24 . The electric motor/pedal assist no longer kicked on when prompted. I contacted Amazon and started a claim , they advised me to contact the manufacturer as this bike has a 1 year warranty. The manufacturer responded within a few days and sent out a new controller. Then in March of 2025 one of the tires blew out , I contacted the manufacturer again and they sent out a replacement inner tube within 10 days . In April of 2025, the rear break line broke, I was like here we go again!! I emailed the manufacturer again, and they sent out a new break line within a 10 days . Then unfortunately in May the frame broke! I was so frustrated at this point , I paid a lot of money for this bike and it just kept breaking down time after time and we didn’t even have it for 6 months ! I emailed the manufacturer 1 last time and advised them what happens sent all the pictures. They were very prompt and sympathetic about the issues we had been having and got back to me within a week and advised me that they were sending a brand new bike directly from the manufacturer also stating they were not going to send a refurbished one which made me think.. hmmm maybe Amazon sent me a refurbished bike at the time of the initial purchase and that’s why it kept breaking down!! I only gave the bike 4 stars because the manufacturer was so responsive and really stood behind their warranty . We have the new bike now and fingers crossed ..
