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,

Great bike, looks to be nice quality. It was 80% assembled and final assembly was easy. The speed controller is not complicated and works great. The gear shifter works perfectly. I've had it 9 days and rode it with my dog couple 1/2 hour trips and the battery is still at full charge. The power level is ideal it runs up steep inclines with ease ( and I'm 6'2" 203 lbs.) Its worth the money.

This is a good e-bike for the money you'll pay. It's not a fancy model worth thousands of dollars (obviously) but it's sturdy and gets the job done. *Tip: be sure to check everything that comes in the box & immediately contact the company if you're missing anything. Mine was missing one tiny allen wrench & I didn't think it was a big deal until the control panel almost fell off the bike during my first long ride due to loosened screws holding it in place. To their credit, 'Jasion' did pay to have replacement screws and a wrench sent to me in the end, but it could have been a much bigger problem if the control panel was damaged.Final Verdict? It's a good bike produced by a good company. Just make sure you have everything you need to go over each and every screw on it & tighten down All of them before you even take it for a test ride.

I can't say enough good things about the quality of this bike. You can expand the pictures and get an idea. The bike arrived in reasonable time and there was absolutely nothing damaged. I was very impressed by the fit and finish. After assembling the bike however I had a problem. An error code condition on the display and the bike would not run. I contacted support and after I figured out they're on a 12 hour or so delay, because I believe they're in China, I felt Support became very responsive. The first thing they requested is that I check to make sure all connections on the bike were secure. Now the electrical system on this is very simple and so after my exhaustive checking of all possible electrical connections in the bike for shorts, loose connections or bent pins Support agreed to send me a new controller. We both agreed that should be the next step. After my initial problems with the weekend communication, Support has an email waiting for me every morning with the next step. Jasion customer service, Support and the forum have been very responsive now making sure I'm satisfied. And I will say all in all after I understood the time zone differences they have been very responsive and I am satisfied. Things happen, parts don't work and staying in touch with the customer to resolve their issue is very important. What I received from Jasion is a quality bike from top to bottom. The fit and finish on this bike was absolutely fabulous. The joint welding is superb, the paint job is fabulous, they do not skimp on the disc brakes, hand brakes, digital display, seat or any part on this bike that I can see. Their wiring of the bike is simple yet protective. I really can't say enough good things about the quality, I received a new controller within 5 days and it took me less than 20 minutes to install it and the bike is running. And running very well I might add. My first day I did 14 mi and hit 20 mph and battery life was excellent. It's been a few days now and everything is working just great. I can't say enough good things about the bike, the customer service and their Support.

Very good and sturdy e-bike, I was suspicious about it but I couldn't be more wrong, it rides very smooth and it has a good top speed. Very recommended.

I've only had the bike a couple of weeks, but so far everything seems to work exactly as expected.Initially, I had a problem with the chain skipping in 7th gear. I tried all the derailleur adjustments suggested on YouTube but wasn't having any luck. Jasion's customer service is very good. They had multiple suggestions, and when these didn't work out they suggested I take it to a bike shop and they'd pay for the repair. It turned out the bike shop recognized the problem right away and the repair was so easy they didn't want any money for it.I can't say anything about the bike's durability, but so far the it performs very well. Fun!

Solid bike, good quality for the money, rides nice, so far very happy.

Writing this review after 3 month of use. Took this bike for a trip in Banff , Alberta recently. Battery lasted exactly 42 kms in 4 hrs. Had power on they out the trip. Had 2-3 setting for half the trip and it was able to keep up really well. I recommend this bike for anyone buying for casual use.

Not a good product at all. First bike's rotors broke down within 3 weeks. The company offered a replacement bike. Which also died after 3 weeks. Now, they are not willing to take the return. Offering replacement part. There is no surety if that works too. Wasted money and now bike is sitting in garage.
