Wow this bike is beautiful, fast and excellent off road durability. I enjoy the 2000w power to get up to speed with the PAS and throttle. Along with its very easy to use control display, you can connect your phone via Bluetooth, activate cruise control and monitor your mileage and speed history. The full suspension is amazing to have off road. I have received many compliments about its appearance and what a great looking bike it is. Took about a hour to assemble with included tools!!! With the amazing features and quality of this E bike it is definitely worth every penny. I use it daily and the battery is strong to last for my commute to and from work.

It's good, but warning in the state of Wisconsin this is legally considered a motorcycle, found out after I bought it. (Check your state/countries laws around bikes outside of class 1-3 cause they'll either be considered a moped or a motorcycle it seems) Also it runs fast, I am limiting it's speed to 20mph but it can hit 25mph despite that and I'm talking about on straight roads not downhill. (I suspect that the bike is too powerful here and they didn't account for that when people are lowering the speed, it isn't properly calibrated to match the speeds 1-1) Regardless it's a fun bike and I hope to find somewhere to go full out on it, but until I get it registered and insured I'll be limiting it to class 2 speeds. Also it's probably the most comfortable bike seat I've rode on.

Received my Jasion Thunder last week and have ridden it 32 miles already. I am very impressed with the bike. I got it to replace another bike which felt too big for me and I find the Jasion much easier to adjust to my height. Love the seat - much more comfortable and the throttle is easy to operate without fear of over accelerating. Haven’t ridden in the mountains yet but seems like it will have plenty of power for the trails. Excellent price, easy assembly and great ride. I would definitely recommend this bike to friends and family.

This is my first e-bike. I'm 6' 250lbs so I got a larger e-bike to haul my arse around. I've put about 50 miles on it so far and I've enjoyed it quite a bit. My primary reason for getting one was the current price of crude and gas going over $6 a gallon in my area in California. Running small errands, getting fast food or just wanting to get out in some nice weather. The suspension does the job. I've had several spine surgeries and the rear suspension dampens the bumps very well. I've gotten it up to 38mph on flat road. More than fast enough for town traveling. One safety warning. I won't lower my star rating but want to still put it out there. I adjusted the handlebars to rotate them a little. Went on a ride and discovered I had no brakes. Was quite confused as it had brakes before the adjustment. Since I know how brakes work, I could tell it wasn't getting any pressure from the hand grip. I opened the fill screw on the handle bars that has the mineral oil for the brake pressure. Rotating the handlebar seemed to release some air bubbles and lost all pressure. I added a few drops to each reservoir. Brakes worked fantastic after. I would definitely check this. You'll need a T10 torx head driver.

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!

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.
