I've had this bike for about 2.5 months and put a bit over 300 miles on it. Loved it so far. Disclosure: I am not a biker and knew basically nothing about bikes before this purchase.My use case: I'm living in suburbs where a walk to work or the nearest shops would be 30-40 minutes. There's also a small city about 7-10 miles away that friends like to visit. I don't have a car here, so I wanted a means of transport faster than walking and more reliable/flexible than public transit. I now use it for my daily commute (~10mi there and back) and getting into town.Assembly: Following the linked video was pretty easy, and all pieces/tools needed were there. One of my pieces on the front bracket or something was slightly warped, but everything still fit. The tires come with very low pressure, so make sure to pump em up a smidge before test riding. Otherwise, all went great for me.Features: Lots of great things, a few minor cons- Operating modes are great. It's easy to flick between 0-3 levels of pedal assist (PAS) which starts up after you begin pedaling pretty quick, and the throttle is very responsive. Motor is pretty quiet too! All of the buttons are simple and very effective for me so far, and the display is clear and easy to read- Speed is exactly as advertised. On PAS 3 w/ full battery on a flat stretch ~20 mph (wear a helmet!). Anecdotally it seems like when you're at lower battery, your max speed drops a smidge (maybe down to like 17mph at 2/5 battery). PAS 1 is around 12 mph, PAS 2 around 16. This has been awesome, since you can basically choose how much effort vs. speed you want to put into the commute.- The battery life is pretty good I think, though I don't have much to compare to. I haven't tested the limits on flat grounds, but I did a 20 mile trip once with a fair amount of hills being very liberal with the battery usage (lots of PAS 3) and it died just as I hit my destination. Mind you I'm a big dude with a backpack full of stuff, probably totaling right around the 265lb recommended weight limit of the thing, so I'd say that it matches the advertised #s fairly. When it talks much longer distances, I'm imagining it means using PAS 1 on a lot on flat stretches for lighter people.- Battery charging speed is basically as described - it's no iPhone speed, but it's probably safer that it doesn't charge too quick! With the detachable battery, it's super easy to bike somewhere, bring the battery inside and charge it wherever. Charger also has a nice LED that shows when its done charging.- Brakes are strong. My front brake is squeaky, which is probably a fix-able thing, but it's not too much of a big deal for me.- The wheels and tires seem fine. I stick to roads and bike trails, and while the center line of the back tire seems to have been chewed down a bit quick, it still seems to work fine. I did go fast over some huge bumps once and blew out the back tire tube. Replacement was as simple as "Unplug the motor. Now replace it like a normal tire / tube", which was easy to follow over Youtube.- The front wheel suspension is awesome. Makes rides remarkably smooth.- Front light is bright. Back light is separate from the electronics of the bike/motor/front light but seems fairly bright, works well, and has pretty good battery life from what I've seen- The paint scratches pretty easily it seems. I'm not 100% sure what I've done aside from get scuffed by an occasional tree branch, but there's quite a few bits of exposed metal around now. Not ideal, but oh well.- The screw for the handlebars gets a bit loose once a month or so. Easy to fix, just a minor annoyance - definitely don't throw away the tools that come with the bike for assembly!Tips for use:- If you're going a fair distance, try to keep PAS low and maintain a fair speed (say >12 mph) instead of just blasting PAS 3 the whole time. Else you may risk the battery running out on you!- Having a helmet, a mirror for the left side, and a phone holder has been all I needed in terms of add-ons. If you're also new to bike-owning like I was, you also need a tire pump (+ pressure gauge), a bike lock, and probably want a simple repair kit. The few times I've biked through small puddles and things, some water has flicked up at me, so if you live in perpetual rain or are going through muck, mudguards or fenders are probably a fair investment.- While it's not recommended, I have used this in some pretty heavy rain once or twice, and everything went fine. I wouldn't recommend attaching the battery while the contacts are wet or anything, but seems kinda safe, and if you care to you could probably just cover the battery connection area with plastic or somethingOverall: This is exactly what I was hoping for when I got an e-bike! It's incredibly fun and fast, I can put as much effort in as I do/don't want to, and the flexibility of charging the battery wherever is great. Definitely recommend to anyone in the same boat as me who regularly have distances that are too long to walk but short enough that public transit (or driving) is silly. Wish I had one of these while I was in college!
