Establishment

Thunder was born from a bold vision: to create an all-terrain eBike that seamlessly blends the thrill of outdoor adventure with the practicality of everyday urban commuting. It effortlessly tackles rugged trails, snowy paths, and urban streets.
Our goal wasn’t just to build a capable machine, but to create an eBike that inspires freedom and exploration. Thunder empowers riders to go farther, explore more, and commute smarter—without compromise.

Fat Tires for All-Terrain Dominance

Design

From the start, fat tires were a non-negotiable. Thunder is equipped with 26x4” wide, puncture-resistant tires—perfect for conquering snow, sand, gravel, and rugged trails. The wide contact surface enhances grip, stability, and comfort across unpredictable terrains, while delivering a smooth ride on city roads. It's this versatility that makes Thunder a true all-terrain beast.

Built for Comfort and Control

Craftsmanship

Thunder is equipped with an adjustable front suspension fork and hydraulic brakes, delivering smooth rides and reliable stopping power on any terrain. Whether climbing rocky trails or cruising city streets, you’ll enjoy enhanced comfort, control, and safety every time you ride.

Your Best of Sweat All-Terrain eBike

Finished Product

Thunder is built for riders who demand power, comfort, and versatility. With a 750W (peak 1500W) motor, adjustable front suspension, fat 26x4” tires, and hydraulic brakes, it’s ready for any terrain—snow, sand, mountains, or city streets.

From daily rides to rugged adventures, Thunder is your ultimate all-terrain eBike.

Suggestion: Heavy bike for smaller or female riders - would recommend 20” for small builds.
More than expected

Was surprised at the order to delivery time - well done. Set up was smooth and complete in 1.5 hours - nice video on assembly. Only disappointment: wasn’t familiar with details regarding the ride experience- should do a quick video on user interface and technique on riding an e bike bs bike or moped - the pos settings took me a while to figure out.

Suggestion: Instead of a switch on the battery under a small rubber cap, maybe an added key position can be used to turn on the battery powe.

Excellent eBike!

This is my second e-Bike and I'm very happy I chose the Jasion Thunder. I consider this to be a luxurious e-Bike; 1,500 watts of power is luxurious and the well controlled gentle ride is luxurious. I chose the bike because of the power, the UL2849 certification, and the shorter wheelbase which makes it possible for me the transport the bike on my hitch mounted bike carrier. The bike is very complete with the awesome color display, lighting front and rear, turn signals, horn, and rear rack. The bike features an App to allow you to control settings of the bike and update software, a feature that I've not seen on any other e-Bike. The Thunder also has a cruise feature that holds your speed so you don't need to pedal or use throttle, just sit and enjoy the ride. The 4 inch tires feel much softer than the 2 inch tires I had on my old bike and do a good job absorbing bumps. I chose the Blue color but there's 3 colors to choose from.

The assembly took me about an hour and was not difficult. The bike came with a 2 year warranty but I assume that means parts if you need them. In my opinion, if you're capable of assembling a bike that you purchase online that you could also make adjustments or repairs as necessary. Or take it to a local bike shop. I've been working on my own bikes for years so this isn't a problem for me.

I had to address a few items after assembly but were not difficult:
1) The seat post wouldn't hold the tilt of the seat no matter how much I tightened it. I replaced the seat post with a Zoom spring seat post that I wanted anyway.
2) The gear derailleur needed to be adjusted. This took me 10 minutes.
3) And the front tire was not installed on the rim centered so it had some wobble-hop. I just repositioned the tire on the rim and inflated, not difficult.

I tried contacting Jasion support and they answer the phone within a couple minutes and they respond to email next day, good to know.

I'm enjoying the Thunder very much and I'm sure you will too, good choice!

Suggestion: Shimano calipers or kendra tires would be an solid addition. Over all very solid bike and love every aspect and the care put into it
Very effecient and powerful

Hands down one of the best ebikes ive owned " ive owned 5 now". This bike blows the competion away. Jasion really took on the challenge. Their first fat tire ebike is fantastic. From the solid frame and tires to the responsive brakes and electronics. Nothing about their " thunder model missed its mark. Furthermore jasion stands firmly beside there product. Had an small shipping issue " damaged component , minor cable damaged" Lucy was extremely knowledgeable and prompt. She quickly responded, trouble shooted the issue and explained the steps and options to me. Sadly being an brand new model my part would need to be manufactured and ship from the factory direct to me. But to compensate we discussed an free accessory for the wait and she and her supervisor had no issue meeting me halfway and overall very satified and look forward to buying more from them in the future.
