Let's first talk about what this product is, at least in my opinion: A Minimum Viable Product.Minimum Viable Products don't have fancy features or doodads. They do precisely what they are supposed to do, simply, and dependably. That's what this bike is, and in that light, my criticisms are pretty light. Value is exceedingly good on this bike. Note that I've added a rack to the back of mine.The Good: The electric drive-train has PLENTY of power. Seeing 500W bikes on the market, I was afraid I was getting something too weak, but that is definitely not the case. 20 MPH operation is pretty easy in the higher assist modes, and 17 mph is easy in the lower assist modes, in an upright riding position, for a low-fitness, overweight person. Packaging was great, everything arrived, and assembly was fairly straightforward (tools are included except for the recommended torque wrench). The tires have confident grip on the pavement, even on wet pavement, and the fenders keep water off the rider for the odd puddle. Five assist levels plus the hand throttle makes for lots of options. Finally, the manual is surprisingly good for advising on maintenance (if it is a little generic for assembly).The Bad: The big things are things I don't think this bike was ever designed for anyway. First, the battery is small-ish at only 36V 5 Ah. That means the bike has 43 minutes of no-pedal operation. It's hard to know exactly what your power usage is, so you might effectively double or triple that. Considering the price of batteries, versus the bike itself, I think this is just something to be aware of going in, not a deal breaker. For more range, you either need another bike or more batteries. Second, the bike is fairly heavy! I really notice versus my aluminum frame bike of about the same configuration. Considering this plus the additional speed of the bike when in e-Bike modes, the V-brakes are sufficient but not ample. Third, this bike is not really for short folk, despite claiming to fit people who are 5'4". Measure your inseam: less than 19" you will need a different seat tube. If you need a different seat tube, you might not be able to add a rear cargo rack that attaches to the tube. Fourth, the handles and seat feel a little cheap.Misc: I had to remove the thin washers for the front V-Brake to be properly spaced, otherwise it rubbed. The electronics say hold 3 seconds to start, but for me, it was more like 10 seconds for the first start. The charger is roughly the size of an old laptop charger (or gaming laptop charger) and outputs 84 W, so expect 2+ hours to charge from empty. You have to lock the battery for it to stay in the holder. The box claims max rider weight of 265 lbs. The cables at the front are a bit long, which I think is mainly to make it easier to ship with them pre-attached. My kickstand was too long to function at all until I inflated the tires.
