    • We love this bike!
Color: Light Green Frame Type: Step-thru Ebike
Review Image by Ed Heffernan
We love this bike. It's our second purchase from Jasion and we love their customer support. We had no issues with the bike, but they contacted us to make sure that everything was good, and that we were happy with their product. The shipping was 4 days faster than expected, and the bike arrived in great condition. Assembly is easy and they provided all of the necessary tools. I bought this as a birthday present for my wife, and she wasn't sure that she wanted an e-bike. After her first ride, she was convinced and put her standard pedal bike up for sale! ... show more

    • Great bike without the big hit to the wallet
Color: Light Green Frame Type: 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

This is a great e-bike. I am 5'3 it is a bit tall to get on but I love ❤️ how tall it is plus if you want it taller you can raise the seat or front part of the handle bars. It was very easy to put together. When you are putting the back wheel together turn the bike upside down to make it easier. Other then that this is a great bike. I also got a Heybike it is a great bike as well that is the pink one I'm the background. I love ❤️ these two bikes. The battery for the Jasion bike last a very long time long as you do not ride on high speed. Great for going ti school or work ❤️. ... show more

    • Decent 7 Speed E-Bike For the Price
We bought this bike after the batteries failed on our old (different brand) bikes. Our old ones were 21-speed and I was a little worried about going down to 7 but I find it easier to manipulate and get it right going up steep hills. The three electric speed options are a little odd. I don't really like Level 1 as it doesn't seem to provide much assistance at all so I end up on Level 2 most of the time. This provides great assistance on hills and on level ground I can average about 15 MPH with comfortable effort. The battery life is good. I was able to go over 20 miles on level 2 on mostly flat terrain and the battery didn't show any drain. On very hilly terrain I get 20 miles and more. The display is okay and the batter level indicator seems to be fairly accurate. It comes with a light and buzzer you can control from the handlebars. We purchased 2 bikes and the buzzer was faulty on one of them but it wasn't a big enough concern to contact support or try to return. Assembly was straightforward and took maybe 30 minutes for the first one and 15 for the second. ... show more

    • I love it!
Color: Light Green Frame Type: Step-thru Ebike
Best thing I ever bought myself! The most confusing part of installation was where to attach the light. I ride every evening about 4 miles in my neighborhood and only use about 15 percent of the battery.

    • Best e-bike in the market
This is excellent e-bike and highly recommend it. Easy to assemble, my 16 year old son did it without any issues. The bike is sturdy and rides very smoothly. My son needed one for school and I was hesitant at first but after reading the reviews and the details of the bike I chose this one. I am clearly not disappointed. It was a great choice. Must recommend this to anyone thinking of purchasing an e-bike. ... show more
