  • 1st impression is very nice unit
Shipping was slower than i would have liked. Box was damaged upon arrival but did not appear to affect bike. Assembly was very easy. Acceleration is instant compared to the other 3 e bikes we have. The best part is the seat itself feels much more comfortable compared to my Amyet bike. I will update review as i give it more use but so far so good. ... show more

  • Smart screen not working
Color: Black
Don't waste your money smart screen does not work comes locked from factory and cannot fix after 2 weeks working with the greatwork support they have no resolution they keep telling me the same things that I entered wrong code I turned on screen hit the +- together to go to modes and it went directly to a 5p screen and it's locked there you can't toggle up or down to enter 1313 password that they told me to enter you can't toggle to 6p screen it's locked on 5p I've been telling them this numerous times. Simple just send me a new screen instead of me going crazy for 2 weeks trying to fix with no results. Other wise ebike is very nice for price. But paying 1k with tax and $199 delivery you expect a working ebike. So far it's just been an expensive lawn ornament. ... show more

  • 💫💨💯
Color: Black
It pretty much lives up to all of the claims in the description. It's the best one I could find for That price range. Especially for the wattage. It's fun off road too. But you Have to keep the goose neck tighten down To the fork column There are. 3 Allen screws on the goose neck and 2 Allen screws on the forks at the top. That keep the bearing pressure in the column Tight. That part is Not the best design.But (if you keep it all tightened up) It's pretty strong. Also I Added a bag And mirrors it looks pretty cool. ... show more
