Thanks for the Help with the power issue...I got everything up and running. I also figured out how key pad works with bike.
Last but not least. The reason why I brought bike was because of the innovated design. And the ability to unlock bike to upgrade performance.
After watching 100s of vides. There is no corrected Unlock working video for the OUXI Q8 bike H6C LCD display.
But for the OUXI V8 bike H6C LCD display there are lots of videos.
I need the correct way to unlock speed for the OUXI Q8 H6C LCD display.
PLEASE HELP

This bike does not disappoint. The instructions are easy to fallow. And was very easy to put together.
I did find that the rear shock was way too stiff. Being 1000 lbs. so I replaced it with a 450 lbs shock. 4.9” but you can easily install a 5.9” or a 6.9”. Now I’m 6’ tall and 220 lbs. and the bike is rated for 330 lbs max. So I find that the 450 lbs shock is a perfect fit. It makes the bike way more comfortable to ride. I also added rearview mirrors and a thumb throttle attachment to the half twist throttle. Because I mostly use the pedal assist with the bike. And not use the throttle.
I’ve already done two 28 mile rides with the bike on pedal assist three and pedal assist two mostly I do use the thumb throttle to power up some of the steeper hills or switch it to pedal assist five but very seldom and I’m usually in third gear on the seven speed gear shift.
But I would not recommend this bike to anyone who is under 5’6” tall. And I sit in the middle of the seat when I ride. Mostly paved bike trails and city streets. And it will hit 30-31 mph on flat ground. Which is plenty fast enough for me. My Beach cruiser 26 inch fat tire electric bike maxes out at 25 miles an hour but is not as comfortable to ride since it has no rear shocks.
I would definitely recommend this bike, but I would also replace the rear shock. And it’s pretty easy to do. And like I said. The 4.9” 450 lbs works very well but I will be trying the 5.9” 450 lbs shock next.

Update. I’ve now have done a range test, hill climbing test with both bikes. I can climb some of the steepest hills with both bikes in third gear sitting down paddling and not having to pedal with that much effort to get up the hills and as far as the range with another 28 mile ride and still have half the battery left. And that’s in pedal assist level three. The new rear shock works great on these terrible California roads.
And customer service is very responsive. At least I have had no trouble getting a timely response from them.

So far the bike is nice. Rides good, came with easy assembly instructions and was easy to assemble. The parts that does not work well for me are, the keys are only for the battery. They don’t do anything besides that. I would’ve liked more security. The seat is super uncomfortable. My thighs hurt for 3 days after only riding for 20 minutes off and on. I now have to get a seat cushion because the stock cushion is painful.

I got on an accident with this bike because the screw where the headlamp and mudguard go was loose it kept getting lose as well it’s a good bike overall but please take off the mudguard and mount the lamp with better screws that will stay in it might save you from a large medical bill like mine

This bike is like no other, it is massive looks like it can go any where you want to take it. i cant stress how solid it is. i ride it at a minimum of six miles each day i go out it is almost like riding in a luxury car, there are no rattles or funny noises to be heard it is just a solid ride and it sits you high enough to where you can be seen by the other traffic. And don't let me forget the about the customer service from the manufacture i wrote to them but didn't really expect for a couple of day to be honest, but no it wasn't even a couple of hours. They answered all my questions, and they even wrote back to me to check if everything was working the way it should be. So to be honest a Five Star rating is not enough it should be at least 10 stars. Again, whoever purchases one of these bikes will not be disappointed.
