    • Best thing I have bought this year!!!
Color: M8 Black
Very nice quality!!! The seat on this thing is awesome! Comfortable for long hauls. I have put 45 miles on it so far. I got it to ride from town to town in the rural area I live in. I can get to a place 15mi away round trip on country roads and lots of hills on a single charge. Now that is using just the 1 motor and avg about 30mph. Using dual motor mode (the turbo button I call it) does blow through the battery but it is fast and fun to do. I have had it at 39mph. So I am stoked!! I have gotten a lot of compliments on the looks and design. This thing is very very sturdy and well built. If you want durability, some good range and power to have fun...this is it!!! ... show more

If you’re looking for a good quality e-bike that’s built really well, this is the one! It comes partially assembled and it took me about 2 hours to get mine completed. It’s fairly straightforward and the instructions are fairly good but do lack a few of the fine points, but easily figured out. It’s a total blast to ride and it does get up to the 40mph speed on a flat paved surface. Like others have noted, it is a bit heavier than most bikes but the dual motors and the bigger battery is a good trade off. I love mine and I really would not hesitate to buy this one again! ... show more

CONS: Flat tire’s twice the first week (glass chip. & Brake rotor metal chip). Delivered in box scratched up on pedals and rim. Power wire harness was ripped open. PROS: Battery lasted long for a heavy guy. So decided to keep the bike and replace the tires and tubes with heavy duty ones. And a wider more comfortable seat. And extra lights in wheels and rear end. And a Asian basket in back. ... show more

This is the second ebike and this one is better built, and a lot more powerful than the other ebike I have. Customer service always answers my questions in one day. I recieved the bike earlier than expected and packed very well.

    • its well worth the price and the effort to assemble.
Color: M8 Black
WOW. first beware its not an easy assemble for 1 person, Its heavy, its a beast and im 6'4 200 lbs and mechanically inclined. Some of the hex screws arent great quality metal and strip easy, so take it slow when tightening. I also found installing the handlebar before the front tire was helpfull as it just gets in the way. If theres 2 of you probably no issue. The battery has to charge for 7 to 8 hours first time, dont give up on it. Bike is sturdy, and FAST. Controls are easy to use and figure out. If I forgot to mention...ITS FAST.... brakes are great, its comfortable, suspension is great, head lamp, all of it. ... show more

    • Great Quality
Color: M8 Black
My Greatwork M8 PRO just arrived today and it is more impressive in person than I could have imagined. The dual-wheel assist is quick and really adds a punch. No hassle on the order or delivery. Set-up was simple and quick. Highly recommend this e-bike to anyone in the market. Thanks for the recommendation Ophelia. Have recently had issue with the pedal assist about 85 miles into use. Needing help discovering why it no longer maintains assist as it did when I started. ... show more

    • Worth the price.
Review Image by Randy Abramovitz Randy Abramovitz
It was quite easy to build, even though the instructions were not perfect on details. It took about two hours to unpack, build, and adjust. The left and right turn signal wires are not identified so you have a 50/50 chance of reversing them. The bike is very rugged and has a comfortable seat. It rides smoothly and can easily hit 20mph. I drive it locally, so I probably won't see the top end speed, whiskers is 45MPH. Most of the time, I try to pedal for the exercise. It is worth the price. ... show more
