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 money Edit: 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 almost canceled my Jasion EB5 order after reading some scary reviews about missing/damaged parts and other issues requiring contacting Jasion customer support. To my surprise, it arrived fast, assembly was quick and painless (under an hour), and everything was perfect—no missing or damaged pieces! The ride is good and everything so far feels sturdy and reliable. Sure, I’ll watch for typical long-term wear like battery fade and tires, but so far? It’s been a smooth, enjoyable experience all around. If you’re on the fence—go for it!

Let me first just say I really love this bike and in three months have put 500 miles on it. Use it to go a few miles to the train station, to the gym, and to the grocery store. It is solidly built, has great acceleration, battery life is no problem for the way I use it, braking is excellent, it can go on grass, dirt trails, sand, rough terrain, most anything, the headlight is strong and very bright, the full electric or pedal assist are great. Having said all that, there are three issues that I have found. 1) The power cuts off every once in a while when I am using full electric or pedal assist. This happens at least once every 2 to 3 days. I cycle the Pedal Assist Level while I am riding and the power will come back. This is only slightly annoying and power has always come back. 2) Went to ride the bike the other day and the front tire was completely flat, not one molecule of air left in the tire. There were no huge nails sticking out of the tire, could not find anything wrong with the outside of the tire. Have contacted Jaison customer support as the bike has a one year warranty. 3) The part of the rear tire that is in contact with the road is completely bald. I have seen this in another review. Maybe because power is applied to the rear tire....but it just seems odd that it got bald after 500 miles. And it is a mountain bike tire with big nobs all over. Will contact Jaison customer support about this too. But overall I absolutely love this bike...I will take care of my tire issues and be on the road again soon!!!!!

Sofar best entry leve E-bike for price and parts. The throttle came falling off the handle bars but I was changing the grips anyway. So bought a finger triggered replacement throttle for $12. And replaced the front and back tires for more durable ones. Bike runs amazing. For a 350 watt was not expecting to have so much range. For the price this is a Grade A bike. Looking forward to doing commutes with this bike. I got the bells and whistles for it too, will post pictures and update review when I finish setting up the upgrades.(One week ownership) Edit: It’s been about 3 1/2 weeks of ownership. I still think it’s a good e-bike for the cost. It meets my power needs, look through the manual and turn it into a 5 level PAS instead of the 3Level it comes default factory settings.(this will help conserve power) I’ll do quick trips around the neighbor hood(groceries, gym, cruzing) roughly 7-10 mile trips there and back. Usually it’ll knock down half the battery(2-3 bars/5). Im mostly using the throttle, ill PAS up hills. I’ve stress tested the battery and done 26miles in a day, roughly 70% of my trip was throttle. Didn’t break a sweat and was fun to ride. The assist makes hills effortless. You need to learn how to ride it between shifting gears and the level of PAS you use. Easy learning curb. So out of the box, my throttle was falling off handles as mentioned before, then the adjustable stem connecting the handlebars kept coming loose so I bought a new one. Doing research I’ve found that the tires that come with it will usually puncture easily so you will need new tires. My rear break was squeaking so I bought new brake pads and replaced it. It’s a solid bike for the price but be prepared to give some TLC if you wanna make this your daily commuter. In total I’ve spent a mandatory $90 on the replacement parts(new wheels,new grips,new throttle,brake pads,new stem) Not sure if the stem was a problem for others as I am an aggressive rider and love to take it through dirt and rocks. Popping on and off curbs. You will probably just need new wheels $30 otherwise it’s a problem waiting to happen if you’re using their factory wheels and you’ll soon be walking home on one of your trips. I didn’t want to send it back but I’m sure the company would have replaced the other parts if I was willing to wait and reship the bike but I was planning to do these upgrades anyway. I also have a new bike seat, nothing wrong with the one they give you. It was comfortable, I just wanted more padding for longer trips. I have a rear rack and pannier bag, added the mirrors, phone holder, cup holder, alarm system, FENDERS(you will need) buy cheap ones $5, turning signals and night lights on the wheels. I must say that you should be carful when installing upgrades because the paint will scratch off if ur not cautious. Not good to leave exposed metal to the elements. This has been my experience with the bike sofar. It works for me but forsure there are some better options such as the ancheer 500w and maybe the tot guard if it’s a 500w can’t remember but those are also available on Amazon. I will be upgrading my battery and installing a second one soon to 3x the power ($250) so I’m not to worried, eventually I’ll also get a better motor but this is my first e-bike. If you don’t plan on upgrading your bike and just want something that needs no fixes out of the factory then I’d explore other options.

Bought this bike march 28th when we pulled it out of the packaging (which was top notch), and looked at it, it looks sharp; it cost $150 to ship and deliver (even with prime) bike was delivered the 4th, we put it together April 8th (my son's 17th bday, this was his gift), got the bike all put together. Instructions could have been more detailed. Attempted to turn on battery and bike, and absolutely nothing, like the battery was beyond dead, recent reviews on youtube (within 4 months) have said the battery comes between 30 and 70% charged, not the case for us. So we charged the battery for over 6 hours, tried it again and absolutely nothing. Reached out to jasion customer service and they said I had to reach out to Amazon so I did, it has been over 2 days and no response yet from the seller. The manufacturer, however reached out to me within 24 hours of this issue, however it did not resolve the issue as of yet, because the bike at the moment is just a regular bike, because the battery isn't working. I'll update if and when the seller on Amazon responds, so we will see. It is extremely disappointing, because this is literally the only thing my son asked for, and it doesn't work. I am really hoping the seller will make this right. At this point I have only had the bike for 6 days. Amazon please make this right. 04/19/2024 *update* I do NOT recommend this bike. Yes it looks nice, but looks can be deceiving. First and foremost, Amazon your customer service is top notch. I appreciate everything you did to fix this, thank you from the bottom of my heart for rectifying the situation. I will always recommend Amazon for mine and others purchasing needs. Jasion customer service was mediocre, I feel like they didn't listen to what the problem was, they kept asking the same thing after I explained in detail, I might add, what was happening; jasion said they couldnt help, i even asked if jasion could just send a replacement battery, and i was told by jasion that because i ordered it on amazon, that i had to go through amazon, they didnt even offer to send a new battery or rectify the situation at all, don't get me wrong they apologized for the stress of the situation, but that's it; So no I don't recommend jasion bikes, don't waste your money. Amazon thank you. Amazon issued me a refund, even though it wasnt their fault the battery/bike was defective. Truly exceptional service and thank you for listening, this is what customer service should be you guys rock! Jasion certainly needs to do better. Jasion manufactured this bike and battery but will not stand by their product? I understand that this is supposed to be a "affordable " ebike, but it is still alot of money; and the "affordabilty" is no excuse for using poor quality components in something as important in an ebike as the battery. I have never had issues with any other manufacturer on any other product that I have purchased, the manufacturers have always stood by their products, just not jasion i guess. I would recommend going through a different manufacturer of ebikes. There are several and I'm sure others will stand by their product even if it is defective. Sorry jaison, please do better. I was hoping I could give a better review, but I can't in good conscience do that. All I can say about it is if you decide to make your own decision and purchase a bike from jasion, just consider it a roll of the dice. Hopefully you have a better experience with jasion.

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.

I received my bike today, and after about an hour of riding, I think I understand this product pretty well. For $400, you're pretty much getting what you're paying for. If you're new to e-bikes, or even just bikes in general, you should know that they can run you quite a pretty penny. Anything below ~$1,000 for an e-bike, especially for a brand that isn't that well known, you're basically gonna get a bike with a giant battery and a motor slapped onto it. Now, not that's there's exactly anything bad about the bike. Like I said, it's good for the price. I bought this knowing that I was getting into the "budget" scene, and that's exactly what I got. Here's a few reasons why I'd consider this bike a "cheap, but reliable" option; Torque The torque on this bike is insane! Once you get on and pedal up to MAYBE 2mph, it kicks the motor in and will send you flying. If you're not expecting it, you'll probably end up panicking and crashing like I did. The easiest fix for this is just to set the PAS to 0 with the down arrow, which will completely disable the motor. Once you're up to a speed you like, turn the PAS up to 1, then 2, and then 3. It sort of operates like the gear for a motorcycle if you want a smooth acceleration. Battery Now, this isn't a dig on the battery itself. When I was first setting it up, it was extremely confusing. It'd light up the "charge" bar, then disappear. I just assumed this meant it wasn't charged, so I went and charged it for an hour. It isn't really obvious when it's done charging, it sort of just shows a red light and that's it. After that hour, I took it out, hooked it up, and nothing, again. I messed around with it for a couple more minutes before it finally seated itself properly, and everything worked. So, please make sure that when you're re-seating the battery that it's fully in. One way to tell is if you lock it and you can see the locking mechanism cylinder popping out of the bottom of the battery (which thoroughly confused me at first.) In conclusion, it works basically as well as you'd expect a $400 bike to perform. If you want something that wont send you flying at first, then I'd probably suggest investing in something a bit better, such as a Revv1 or any other American made brand. These more expensive bikes will tend to advertise a 'Torque Sensor' which will more accurately give your motor power based off of how hard your pedaling, versus what these cheaper bikes use called a 'Cadence Sensor', which in short will give power only if it senses that you are pedaling. This brand clearly isn't American if you couldn't tell and comes in straight from China, so the quality will be as such. Keep a close eye on the battery as I doubt it's made with any high-quality cells either, meaning increased chances of blowing up if kept in the wrong conditions. Charge it and make sure it's in-sight while doing so, probably in the living room, or your bedroom. If you want something that's going to last a really long time, or you're gonna use something to commute everyday and have some money to spare, I really do suggest getting an e-bike from a more reputable brand. They'll have all the gadgets that you'll need for a comfortable ride. But, if you're willing to make some compromises, this bike is also totally fine as well.

We love our bikes! We purchased two of them, and one of them had a pedal defect, but customer service send new pedal out and it works great. Great price, battery last longer than expected. I can go a week without charging.
