At this point owning 3 Jasion well built, robust, economical EV’s and I’m very pleased with the products they construct. Now specifically the Thunder e-bike is a beast and incorporates so many features that don’t exist on e-bikes in its price range. This bike is a winner and the company is solidly behind their products and customer service as well. Won’t hesitate on this one, if it meets your requirements buy it now!

Best bike ever. Everyone ask where did I get it! I showed them. Its extra large, great for men or heavy set females. Battery last forever. I barely have to charge. You just get on it and go. No pedals really needed to start.

We've now had these bikes for about 3 months and I feel.I'm able to give an honest review on how we use them and how they've held up so far. They are great for riding into town for breakfast at our favorite local spot, going to get small amounts of groceries, and they were awesome at clearwater beach. We traveled the entire island and are planning to go to Daytona with them for on the beach riding.
I would let you know, however, that these bikes are not met for rough dirt roads.We have popped seven tubes and have had to replace one tire already. So if you live in a real community like myself, tireliners are an absolute must, they are not pre.Installed when you get the bikes.I wish they were as they were advertised for mountain biking and rough grounds, but that is not the case. Jasion has bee amazing at getting replacements quickly and even sent us 2 of the front baskets when one bike was damaged on arrival, broken brake handle. My husband is a very creative woodworker.And metal worker and took the 2 bus gets to create one large rear basket for when we go into town for grocery shopping or for going to the local thrift stores.
My speedometer seems to be a bit off compaired to my husband's bike. Although mine seems to be a bit.
Faster since I weigh less.His will still show.He is going faster than I am.We've even compared it with our S.U.V, the speedometer is right, just figuring that out that is an adjustment in settings. The battery life is amazing even though we charge it.After every ride, we'll use it.As previously mentioned in clearwater beach and took a ride from one end of the island to the other to explore and didn't even drop a cell in battery power. The motor itself does have quite good get-up-and-go as long as the battery is not having issues asked. We've had to replaced both of ours, one was damaged and cracked the other half a few burn spots on the batterycell again the company was amazing at getting us replacements very quickly.
As for appearance, we have gotten several compliments in our neighborhood and all of the people we've encountered have asked us if they could take pictures and where we purchase them at this point I feel like we should get paid for advertisements because it is a 10 minute conversation with each person just about on the different. Attributes and how much we can adjust and change it to our personalities and preferences.
With everything being said, I would say this is a fantastic bike overall.
However those few small things would make quite massive improvements if the bike break mounts were metal and tube protector pre-installed would be one suggestion, last suggestion for all those short people out there like myself. I am 4 foot 10 inches. The full swing through bike I can ride. However, in order to stop, I do have to slide off my seat and stand on my toes. It would be great if there would be an alternative when buying the combinations for someone like my short stature to get maybe a 16 inch tire or something smaller or even lowering the seat, a bit more to those of us who are smaller would be able to fully put our feet on the ground. As for my husband he is 6 foot 2 and the bike is very comfortable for hi've even added a bike seat on his so we can do rides together on one and we don't see any loss of power or drag on the battery when 2 are riding on it, our total weight between the 2 of us would be right at three hundred pounds.

Got the blue Thunder today (friday) and i ordered it monday afternoon. Amazing shipping time. Absolutely sexy bike. The ride is smooth, easy over bumps. Goes to 28 up hill 31 down hill. The size of this bike is nice, its a big bike with big fat tires that just eat up whatever you're on. Wife is 4"11 and fits on this bike nicely. It performs exceptionally well. Goes fast right away and its super easy to pedal. Definitely have to download the app to adjust a few things… but that's no issue at all. This Jasion thunder is a great value for your money. Priced very well for how much bike and power you get. There is a lot of positions the seat and seat post can go in, so its suitable for all size riders. So far the bike has gone 20 miles. Just over an hour of riding and only list one bar of power. The set up took a bit of time, but was super easy.

This is the 2nd Jasion bike we have purchase. We also have the YR20. Both bikes were well worth the purchase!

Very good bike overall. It was easy to assemble and everything came well packed. The shipping was also very fast, which I really appreciated. The bike rides great and feels powerful and smooth. The only issue I had was when I inflated the tire, the inner tube came out of the rim. Aside from that small problem, I’m very happy with the bike and would still recommend it.

My second Jasion for a reason. Solid and fun.

Error with bike immediately after assembling. I haven’t been able to use it yet. I have contacted them about the problem and will update my review if it is quickly resolved
