I'll start by saying this will probably answer (and/or confirm) a lot of questions you may have about this bicycle, so please do read.Shipping Review:Shipping to my location was through FEDEX, not really a problem with them, other than that I hate the company as they have messed up many orders of mine. This specific package never even got an "out for delivery" notification, however this package is supposed to be signed for upon delivery. They did show up in the window and day they said they would though. Overall, 3/5 stars for the company used. I'd prefer UPS (and additionally more options to express-ship this bicycle).Building (putting together) Review:Overall, it took an hour. If you have screw drivers (which I didn't use mine) that have the 3 different hex style bits this bicycle uses, you can do it faster. You should definitely install the front fender at the two bottom screws of the front forks first, then get the top of the fender screw last. Instructions were very poorly written for English, but I didn't expect anything different from companies like these. I never used the instructions for building (but I did read them afterwards). The build is pretty much self-explanatory. The headlight plug is --- VERY DELICATE ---. There are three pins, and if not seated correctly can bend/break. Mine unfortunately came with a missing/broken pin, or I had broken it on accident and not realized it. There really is no fix to this, other than stripping the wire and splicing the connections yourself, which I think I will be doing depending on if the company has a better solution (pending response...) Overall, 4.5/5 stars.Seller/Buyer Communication Review:Pending response... Will update review later.Overall Ride:The front shocks are relatively decent. I wouldn't take this out on the mountains and rocks, but as a road-bike or semi-off-road bicycle it would do just fine. I like that I can lock the shocks when I don't want to feel the bounce or compression of the front suspension. The front suspension is rather smooth for now, hitting a bump in the road/etc while not on lock-out is comfortable. Overall, 5/5 stars for suspension.The bicycle pedals really nicely, the shifting works well and comes all pre-adjusted. In comparison to my other customized ebike (read on to find out about this), this bicycle pedals smoother. I pedaled with practically the same gear-ratio, and for some reason this bicycle I felt less resistance than my custom one per pedal. This could just be due to difference in rear hubs and the resistance within them. Overall, 5/5 stars for pedaling/shifting performance.This bicycle controls are relatively self-explanatory. You do need to hold the middle M button on the handlebar for the display to turn on once you connect the battery. I couldn't figure out how to turn it on, thankfully my other ebike is the same way. There were no instructions to figure out how to turn it on. Overall, 4.5/5 due to not giving instructions on how to turn on the bicycle.The BRAKES! They are not as bad as these other reviewer's say they are. They come loose and can be adjusted to your discretion. All I did was use the adjustment at the handlebars. I didn't even have to adjust the cable distance on the disc brake itself. Overall, 5/5.The SPEED! For myself, this bicycle goes fine, but it is not as fast as my custom-built one. This one leisurely takes off if using only the throttle. To use the throttle, you must leave the system in a PAS mode of 1-5. On 0, the bicycle preforms as a regular bicycle, with no electric functions. There is a way to alter certain settings, but I don't know what settings it alters and still need to research that. There may be a way to turn on throttle with a PAS of 0. Additionally, I was able to obtain a speed (according to display) of 25-26 mph (240lbs male, flat road), but I couldn't get much higher than that (note this test was performed with a battery out-of-the-box.) Apart from only using the throttle to take off, if you pedal (even just minimal) I feel as though the motor gives you even more power. Max throttle at level 5 PAS feels slower than slightly pedaling the bicycle with no throttle at the same PAS level of 5. Overall, 4/5 for the speed. The speeds aren't as advertised but I also wasn't expecting much from a 1000-watt (or 750?? - advertisements are confusing about this) hub motor. I just had hopes that it would out-perform my custom built one.Hills - This bicycle pedals up hills with assist much easier than my custom-built bicycle. Again, this could be to do with resistance in the hubs themselves, however I tested both bicycles and this one isnt a leg-workout even with using the assist. On the same hill (steep incline), this bicycle reached 15mph (per the display) on PAS of 5 (and an out-of-the-box battery). My custom built one (on a very low battery) was able to climb the same hill at a rate of 20-24mph (per display) - and it did feel a bit faster than this bicycle. Overall, 5/5.OVERALL GENERAL INFORMATION TO SUPPORT THE ABOVE REVIEW:My custom built ebike is a 27.5 inch frame, with a 26 inch Volimart 1500-watt hub motor rear-wheel and a 26-inch regular front wheel. The battery is a 52V 15ah battery. This system was put into an old walmart bicycle frame, that barely fit the hub (I had to push apart the rear forks). Shes been a beater-ebike for quite some time, but I love her. She was getting very rusty, so I recently decided to re-paint the entire bike and re-position all the electrical components.The main reason for me buying THIS bicycle is because I noticed the torque specs of the hub motor were higher than my volimart hub motor, even with the difference in wattage ratings. I was expecting a difference on the hills with this bicycle. Additionally, I wanted another ebike to take my partner out on rides. Overall, I don't regret my purchase, and the bicycle is a pretty decent bicycle. I hope my review helps you decide if this bicycle is the one for you :).
