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!!!!!
