Jasion EB5 Electric Bike for Adults with Peak 750W Brushless Motor, 40Miles 20MPH Commuting Electric Mountain Bike with 360Wh Removable Battery, 7-Speed, 26" Tires and Front Fork Suspension

Unboxing and assembling took me about 15 minutes - came 75% charged.It comes with the rear wheel attached, just have to lock the front wheel on, replace a protective cover on the steering shaft with the handlebars - pop the seat on and you’re ready to ride. All the wiring is hooked up other than the front light which is a simple connector.My front brake disc seems just warped enough to rub a bit. I will try to correct this myself if it becomes problematic. I’m just thankful to not be flat on my face anytime I have to use the front brakes anyway.I am 175lbs and wear a backpack when I ride.My test ride was about 4 miles where it went from 75% to %14, and I was admittedly torture testing it a bit. Riding with just the throttle , or taking off from stopped with the throttle, uses a noticeable amount of battery.I kept it usually around level 3 out of 5 pedal assist modes for the trip. I live in a very hilly area so half the trip was uphill essentially. I am not sure exactly how the gear ratio affects the battery, but I kept it in the top few gears for the trip, and the whole ride barely felt like a light workout with PAS.The horn is nice, but I did not get a single person to move, one of their dogs heard me at least. But, everyone has air pods in these days. One of these instances they saw me coming , but didn’t move, so I had to drop off a curb, which knocked the tail light off. I’ll reattach it with zip ties, instead of stretchy rubber strap.The cable that comes with the rear light, is not even half as long as needed to reach the port on the battery. I have a long one lying around easily, but it was something I noticed. The included rear light seems to be from a separate manufacturer so I am not really upset.The main thing I wanted out of this bike was to make my commute easier, living in an area where if I can coast downhill for miles , I have to essentially walk a normal bike back home, from how steep uphill it is on the way back. However, this bike made the hills barely noticeable.Very happy with the purchase and I will update this review with further experience and insight on the battery life and range. If I used about 60% of the battery with leisure use in my conditions, and went 4 miles, I would guess a more realistic full trip in my conditions would yield 7 or 8 mile range tops. Again, I will have a better idea with more trips that start with a fully charged battery.Edit: I made 2 trips to a place 11 miles away starting with a %100 charge, and in similar conditions as my first ride, the battery got down to about 30%, but again, that same percentage might show 40-45 once the bike is stopped. I would say in my hilly conditions a full charge would get you 15-16 miles, maybe a bit more, especially if you ride in a way conscious of the battery life.I messaged the manufacturer to ask if they would sell a spare battery and they said they wouldn’t have spares for another few months. Very happy with my purchase, well worth the moneyEdit:I've had this thing nearly 2 months now and thought this review deserves an update.For the first review, my legs were weak. But, I have been taking the EB5 to commute to and from work every day - 22 -25 miles/day.So, with that exercise, my legs and stamina have gotten stronger. Now, my legs put so much power to the ground that PAS doesn't even kick in until set to level 3 or 4. After my 11 mile commute - and being conscious of when to tax the battery and when to just get a bit of pedaling in - I can get to work or back home with over 65% of my battery left, even with a rack and loaded basket.Given that, it could be assumed that in the same conditions, since 11 miles used about 33%, one could comfortably go 33-35 miles before the battery dies.Some tips:Don't keep your bike in gears 6 or 7 just because the motor is helping you.Keep the bike in whatever gear you would normally pedal in - turn PAS to 0 and find that gear -where your legs arent spinning freely but also not needing too much force -and then work your way from PAS 0 to whatever mode you feel it kick in.Then, once you are at a healthy cadence for whatever conditions you're in - imo 12-17 MPH - turn down again to PAS 0, and now the pedaling is super easy as keeping a cadence is much easier than pushing yourself from a stop to a high cadence. Maybe kick PAS back into 1 to allow yourself to manually use the throttle to get back into a cadence, and then down to PAS 0 when your legs can help again.This way, you are getting some cardio, you are engaged and aware, and maximizing the life of your battery and actually the motor as well - and when you are close enough to your destination, you'll have so much percentage left that you can comfortably give your legs a break and rely more on the throttle.I had been asking the company if they offer spare batteries - they said not until March - they offered to give me a discount on their new bike if I reviewed it - however not an actual discount, but instead, a partial refund, meaning I cannot afford the initial cost of the new EB7 - and through this conversation they maintain that they do not yet sell spares for the EB5, despite it being halfway through March.Some complaints:The screw for the handlebar adjustment comes loose once or twice per ride - it's a quick fix but very annoying, the handlebars become wobbly.The screw for the rear brake adjustment comes loose as well - again, a quick fix, but dangerous, and some people who don't know might go over-adjusting the brakes at the handlebar level, or deciding their brakes need replacement, without realizing that the screw actually just comes loose.You cannot remove the rear tire completely. There is a motor cable running into it, which has a point where it seems it should disconnect, but does not actually disconnect, Im sure if you brute forced it you could jerry rig it back together easily but it does not comfortably break away for maintenance on the rear tire. Changing tubes and tires is a bit of a hassle because of this.There are not enough holes for attaching accessories. There is an unused screw hole on either side of the rear forks, and again unused holes on either side of the seatpost hole - for attaching a rack. However, that is it. no other holes. No indicator as to what kind of screw or thread goes into these holes either.The connector for the battery is nearly proprietary. I found out it can be found online by searching for "REENTION OUTPUT CONNECTOR" - Reention being the company who makes the cases for the battery used by this bike. It's just a + and - prong but I would have loved, loved, loved to see instead an XT60 or XT90 connector capability. Now, to add my own spare battery, I have to rig up a connector and find a place to strap the default battery since its mount would block access to the battery port. I dont like when companies make DIY harder, that's all.The rainwater and road dirt in my face and eyes got old pretty quick, so I did add an aftermarket fender. You can't use a regular fender in the front as the headlight blocks where it would normally go, and again, there's no holes for accessories to have any other place to move it to.But you can use the flexible fenders which attach with zip ties, if you are crafty enough to avoid it rubbing on the tire.I don't know if this company is just a couple of dudes in an office in China with a couple workers putting together the bikes out of the different parts coming from all kinds of different companies ("Jasion" really just seems to be the frame) but given it does seem to be a quality product and sold as described, I am happy with their efforts and the bike.Otherwise, all in all, I'm happy with my purchase. I am getting exercise, I feel great, I haven't been ran over yet,

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!

This bike is my first e-bike, and I love it. I'm sure there are much better bikes, but for this crazy low price I can't imagine anything better. So first month experience: I topped off the battery and got about 30 miles, going up and down hills, riding an average of 15mph. It has 3 levels of e-power, plus you can just ride it with no assistance from the motor. I put 60 miles on it the first month. It has 7 speeds. Changing the gears is fine, but like all bikes the cables get a bit stretched so sometimes it doesn't change gears smoothly. Now that I know what a bit about e-bikes, I wish now that it had a front derailer so that I had 14 speeds instead of just the 7, as I ride with a guy on a normal bike and sometimes assistance level 1 is not enough but level 2 is too much. Has a very bright light, horn, and the display tells me all that I need to know. Really, for this price, this is a KILLER e-bike!
