    • Great bike without the big hit to the wallet
Color: Light Green Style: Step-thru Ebike
Received the bikes earlier than expected and just put them together last week. Super easy. Everything fit together well. For the review on here that had a bent derailleur, there is now a bar that protects it, so no problem there. Took them on their maiden ride yesterday and everything worked great. Struggled a little with power on hills but peddle assist helped with that. Went on about a ten mile ride into town and battery didn’t even go down on the display. Ride, handled, and shifted well. Super comfortableFront shocks assisted on the bumps. Has plenty of speed for me. Came back at night and the headlight lit up the street in front of us. Altogether happy with the purchase. Only issue was a small tear on the bottom edge of the seat but barely notice it. ... show more

    • Great value!
Color: Blue+Green Style: Step-over Combo
We purchased 2 of these, and have about 20 miles on each of them. So far, they are just as advertised. They reach a top speed of around 27-28 on a slight decline. Uphill they do get to 15mph depending on the incline. Love the power assist, however, you have to be prepared when you pedal a little, it will just take off. The battery life has been impressive, in fact, we haven’t tapped any more than 1 bar after several miles so can’t comment on total battery life. Easy to put together, the video guides you right through. Only issue so far is the front light/fender screw. Be careful, one of ours stripped out with very little torque, it must be just plastic nut. Lights are ok, front is sufficient but rear tail/brake/turn light isn’t very bright. Great value for the money overall! ... show more

    • Perfect e-bike for older couple wanting to ride rails to trails
Color: White+holder+bag Style: Step-thru Ebike
We have owned the e-bikes for 3+ months now and taken them on 8 bike rides typically 10-30 miles (rail to trail paths). Overall we have been satisfied but only 4 stars due to the number of small issues we had to address to date. Battery life has been excellent. Pedal assist work well with first assist speed at 11 mph and 15 mph for second speed assist (typically on flat ground and up moderate hills). Top speed is around 25 mph but no idea why anyone would want to race along at that pace. Bike frame and 7 speed gearing is well constructed. Cable management is well done and lighting (brake and turn signals) robust. Assembly was easy. However, elements of construction are cheap (e.g., gear shifter) and both bikes required numerous adjustments to operate correctly with brakes being the main issue. On one bike there was brake drag on the front disc and on the other the back brake was too loose. Took a while but in both situations fine adjustments corrected the deficiencies. One handle bar gear shifter broke on our third trip. It is a well known bike brake manufacturer part but nearly all of the assembly is cheap plastic. Luckily, the OEM replacement part is only $15 and changing it is pretty straight forward. Tires have been our other issue. One tire blew on our first ride and since it was a rear tire and I did not want to deal with rear wheel disassembly to replace the tire, we used a professional shop. Looked like damage to the rim of the tire during assembly or original tire manufacturing. Had shop inspect both bikes and found similar issue with second tire. Again, appears to be a lack of quality control with the tires. So while we had a number of small issues, overall we are satisfied with the e-bikes given their price point and our plan to use them on typically paved or packed dirt roads and rails to trails. ... show more

    • Great choice!!!
Color: Green+Bag Style: Step-over Ebike
This ebike rides smooth and comfortable while riding. I had purchased 2 other ebikes before this one and by far this one is with out doubt the best out of the 3. I like the fact that it comes with turn signals wich is a plus for me. And the battery pops out if you wanted to charge it inside your house. If your looking for an ebike that is well built and fast this is the one for you!!! ... show more

Great value for the money! I ride this thing almost every day and no issues so far. It's plenty powerful and the green looks nice. Hits 28mph as advertised. Customer service was fast responsive and took care of me when I needed help. The derailleur guard came bent which didn't allow me to shift to the top 2 gears. Also the screen mount cracked during shipment. They sent me a replacement immediately so kudos to their customer service. I wouldn't mind getting another bike from them ... show more

Review Image by Faisal Aljaber Faisal Aljaber
I recently had a minor issue with the battery on my Jasion bike, and I was really impressed with how quickly and efficiently their customer service team handled it. Their response was prompt and professional. As someone who has owned 4 different e-bikes over the past 5 years, I can confidently say that Jasion Bikes exceeded my expectations. The biggest surprise was how easy it was to assemble - previous bikes required my partner's help, but I was able to put this one together by myself in my living room, thanks to the clear instructions. The quality is great, especially considering the price point. The bike performs well, and I'm enjoying every ride. If you're in the market for an e-bike, don't look further - Jasion Bikes delivers on their promises. Highly recommend! ... show more

    • research all aspects of E Bikes before buying
Color: White+holder+bag Style: Step-thru Ebike
Beautiful bikes, well made, easy to put together. Only complaint is the throttle button. It should start at "Zero", but starts at "1" which initiates as sharp jerk and off you go, ready or not. You eventually get used to it, but be warned , the first time is a surprise. Would but more if we needed them. ... show more
