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.

I have owned this bike for the last 3 months. I can’t use it anymore, because the frame for the battery has broken off. The rear tire lost it’s tread in a matter of weeks, and the rear brakes do not work anymore. The disc brakes on both the rear and front make constant contact with the wheel. You will not get anywhere close to 20 miles travelled at anywhere above the minimum speed, before your battery dies. There is also degraded performance on the battery itself, it already doesn’t work as good as it used to. It takes nearly 8 hours to charge to get 1 hour of good riding in. The seat is incredibly uncomfortable, and the motor makes annoying sounds when travelling at high speed or on any kind of incline.

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!

I bought this bike in October to save money on Ubering to work. With over 400 miles on this bike, here’s my experience:
Assembly
Simple enough, read the instructions and follow them step by step.
Battery
I commute 5 miles each way, with a couple of big hills along my route. The battery will get me at least 2 round trips (20 miles) on a single charge (with charge to spare) and I barely break a sweat.
The charger gets surprisingly hot, place it accordingly.
It takes several hours to recharge, I usually do it overnight.
Removing the battery can be tricky, as it’s quite heavy and situated in a place that’s easy to get your fingers pinched.
There’s a sticker on the inside of the battery compartment that will indicate if the battery has gotten wet.
If the battery dies, yes the bike can still be rode normally (although it is heavier than a normal bike). No it doesn’t recharge as you pedal.
Speed
In the highest gear, the bike will easily get up to 20 mph on level ground. Even faster downhill.
The amount of torque can be dangerous if you’re using the throttle from a stand still in a high gear. Using the throttle on a low gear can help get through intersections/crosswalks quickly though.
Out of the box the bike has three pedal-assist gears, but I went into the settings to spread it out into 5 to better suit my route and needs. Read the manual for more details.
The mechanical gear shift is a 7-speed Shimano with a thumb shifter – very comfortable and easy to use but not used if you’re going over 20mph. Just sit and enjoy the ride.
Comfort
The seat is as comfortable as a bike seat can be. Easily adjustable even for me (6’1″).
The grips are ergonomic and comfortable, but you’ll have to cut a hole to add a bar mounted mirror (I highly recommend). I also added electrical tape to the brake handles for a more confident grip.
Display
The mounted screen is in the way if you turn the bike over (e.g to change a tire). The screen itself is protected but be prepared to see some scratches on the frame around it.
I wish the display had a clock or altimeter, however, the battery level, adjustable brightness, odometer, speedometer, and current gear displays are sufficient. The trip odometer is a nice feature, but you have to enable the ability to reset it each time you reinstall the battery after charging.
Miscellaneous
The tail light failed after about two weeks, so it’s a good thing I also bought a backup from another seller.
My manual didn’t come with the second half, (it was the first half printed twice) but it was easy enough to find the full manual for free online.
There is no place to mount a water bottle holder on the frame. I wear a Camelbak-style backpack for hydrating on the go.
The headlamp is easily adjustable for the proper angle, and the horn is loud enough with a unique pitch to get people’s attention when needed (even city road workers using loud equipment).
I removed the kickstand because I lean my bike against whatever I’m locking it to and I don’t need the extra weight.
—
As always, make sure you can see and be seen as much as possible for a safe ride. I leave the headlamp on at all times, added reflective pinstriping to the frame, and installed an adjustable bar-mounted side mirror on the passing (left) side. There’s mixed reviews about whether e-bikes can handle wet conditions but to be safe I avoid riding or leaving it in the rain (get a bike cover).
Overall this is a wonderful e-bike for an affordable price. It’s truly a pleasure to ride.

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,
