Cyrusher Aura Step-Through Fat Tire Electric Bike

Cyrusher Aura

Step Through. Power Up. Ride Free.

"Comfortable Power. Zero Compromise."

You want a step through electric bike that does not force you to choose between comfort and capability. The Cyrusher Aura delivers both. A 750W hub motor with torque sensing technology reads your pedal input and responds with smooth, proportional power. No lurching. No delay. Just natural acceleration that feels like your own legs got an upgrade.

Built on a low step aluminum frame with fat tire electric bike stability, the Aura handles pavement, gravel paths, and packed trails with the same confidence. The 52V 15Ah Samsung battery pushes your range to 60 miles per charge, and the 1.7 inch TFT display keeps your speed, battery, and assist level visible at a glance. This is the torque sensor ebike that makes every ride feel effortless.

"We designed the Aura around one idea: riding should feel good from the moment you step on. The torque sensor reads your effort and matches it. You pedal harder, it gives more. You ease up, it backs off. That natural feel is what separates a great electric bike from a motorized bicycle."

— Cyrusher Product Team

THIS RIDE IS FOR YOU IF...

Cyrusher Aura step through electric bike in white Cyrusher Aura fat tire ebike in black
  • You need an electric bike with a low step frame that you can mount and dismount without swinging your leg over a high top tube.
  • You ride mixed terrain and want fat tires that absorb bumps, cracks, and gravel without rattling your hands and wrists.
  • You want a torque sensor system that feels natural and intuitive instead of the on/off surge of a basic cadence sensor.
  • You commute, run errands, and explore on weekends and need one bike that handles all of it on a single charge.

COMFORT MEETS CAPABILITY

Engineered for Real Life Riding

The Aura is not a stripped down commuter pretending to handle trails. It is a genuine all terrain electric bike wrapped in a step through frame that anyone can ride. The upright geometry keeps your back relaxed and your eyes on the road, while 26 x 4.0 inch fat tires soak up imperfections that would rattle a standard tire.

IPX5 waterproof construction means you do not check the forecast before heading out. The integrated headlight and taillight keep you visible in low light, and the Shimano 7 speed drivetrain gives you mechanical gears to complement the electric assist. Three colors. One mission. Get you riding more.

TORQUE SENSOR INTELLIGENCE

Power That Reads Your Intent

Cheap e-bikes use cadence sensors that dump power the instant you start pedaling. The Aura uses a torque sensor electric bike system that measures how hard you are pushing and responds proportionally. Press lightly through a flat stretch and the motor whispers. Lean into a hill climb and the 750W motor surges to meet you with up to 1280W of peak power.

This is the difference between riding an electric bike and riding a great pedal assist electric bike. Combine the torque sensor with 7 levels of pedal assist and a thumb throttle for on demand power, and you have complete control over every ride. Cruise at 28 mph when you need speed. Conserve battery when you want range.

Frequently Asked Questions
Is the Cyrusher Aura a good step through electric bike for beginners?

Yes. The low step frame makes mounting easy, the torque sensor provides smooth and predictable power, and the fat tires add stability. The 7 levels of pedal assist let you start gentle and increase power as you build confidence.

How far can the Aura fat tire electric bike go on one charge?

Up to 60 miles with pedal assist. Throttle only range is approximately 35 miles. Actual range varies with terrain, rider weight, assist level, and wind conditions.

What is the difference between a torque sensor and a cadence sensor ebike?

A torque sensor measures how hard you pedal and provides proportional power. A cadence sensor simply detects that you are pedaling and provides a fixed amount of power. Torque sensors feel more natural and are more energy efficient, extending your range.

Can I ride the Cyrusher Aura in the rain?

Yes. The Aura is rated IPX5 waterproof, which means the motor, controller, and electrical connections are sealed against water jets from any direction. Avoid submerging the bike in deep water.

How fast does the Cyrusher Aura electric bike go?

The Aura reaches up to 28 mph using the thumb throttle. Pedal assist speed depends on your effort level and the assist setting you choose.

Is the battery removable for charging?

Yes. The 52V 15Ah Samsung battery removes from the frame for convenient indoor charging. A full charge takes approximately 5 to 7 hours with the included charger.

I originally bought the Ti, but decided to upgrade to the L5 special edition. It's a very, very good-looking e-bike with excellent design and quality. The texture and build feel top-notch. I think there is no competitor to Async under $2000. After assembling it and taking it for a test ride, I could only reach 20 mph. Thanks to the patience of customer service, I was able to debug it and get the speed back to the normal level. Overall, I am extremely satisfied with my purchase!

Edmond Pineo

I love my L5. It was an easy assembly and is a joy to ride. Great speed and also very comfortable!

I've been finding excuses to take this bike out all week. This was my first e-bike purchase, and it's a huge step up in power from a folding e-scooter, and a thrill to ride. Well worth the wait.

Just took my ASYNC L3 on a camping trip, and it was fantastic. The bike's performance on rough terrain is impressive! Hopefully my parts will arrive soon because it's really hard to ride outdoors without fenders...

J
Julia Johnson

I bought two L3‘s one for the wife and I so far we are loving them. With a large fat tires it feels like you’re driving a tank, but not in a bad way. The torque. It’s awesome when it kicks in. We are so far loving these bikes.

Donna Koch

I’ve had my Async for a few days, I was waiting to write my review. I couldn’t find any problems as of yet. I had a question about my charger and Async customer service was there to help. That alone counts for for my 5 star review. Great job Async! I will soon be investing on the L3 for my wife. After many weeks of research and One attempted failure with TOTGUARD!!! Horrible experience, I lost 400.00 on that transaction. I still have the bike with a faulty battery. I was hesitant to order from Async till I reached out to customer service. I knew then, Async was there to help. Thank you again…❤️ My L5…

I had been wanting an e-bike for a while and finally decided to dive into some research. I started exploring online and talking to fellow riders on trails and bike paths. Everything pointed me to one bike: the ASYNC L3. To put it simply, you won’t find a better bike with all these features for under $1500. The L3 includes many components found in higher-end e-bikes but at a fraction of the cost. The suspension of L3 is amazing I had a very comfortable mountain riding experience! I absolutely love it and would buy the same bike again without hesitation. Live to ride, ride to live.

R
Ron King

I hadn't heard of async before and was initially a bit worried. The price was comparable to an e-bike I was considering from aventon. However, after receiving the L3, I feel it was absolutely worth it. The bike looks cool, has great battery capacity, and I really like the async design. The hydraulic disc brakes are very comfortable as well. The only issue I have noticed is that there are some visible welds on the frame, but they don't affect the overall look or performance. I suppose it's a normal sign of welding. Overall, I'm very satisfied with my purchase

Donald Shum

I waited a long time to receive the L3... the bike is very beautiful, I tried to ride a few laps in the park next to my home, the motor is very stable and strong, customer service is also very perfect(patienly answer my questions) I hope that in the future, async can improve the logistics problem!

This is my 2nd ebike and I'm loving it! Amazing ride, responsive, fun leaning over around corners, technology is great, beautiful looking bike (SE version).

Maria Herbert

I've been interested in e-bikes for a long time, and I had never heard of the ASYNC brand before. I discovered the L3 through a YouTube video review. The look of the L3 caught my eye, and I decided to give this brand a try. I had to wait a while for the pre-order, but once it arrived, I was impressed by the thoughtful packaging and the beautiful design of the bike. For the price, it's an amazing deal. After assembling it, I took it for a ride and was blown away by the motor's strength. The pedals provide stable and abundant power. I still need more time to assess the battery life, but so far, this is an excellent e-bike!

J
Jacob Asay

This is my first e-bike, and after doing extensive research on e-bikes under $2k, I decided to treat myself to an ASYNC L5 for my birthday. It has been an absolute blast! I love the torque sensor and the different levels of pedal assist. The throttle is great for getting started from a stop or tackling hills. The step-through model makes it so much easier to get on and off the bike.

I assembled it myself and immediately went on a 10-mile ride, which only used about 20% of the battery even in a very hilly area. I was grinning the whole time. I did have to adjust the front brakes to prevent them from rubbing, but everything else worked perfectly out of the box. If you're undecided like I was, just go for it! It arrived with a 70% charge, so I was able to ride it right away.

J
Jayme Parks

This bike is a rock-solid tank! A true 'manly man' kind of e-bike! It’s my second e-bike and it doesn’t disappoint. It’s faster, more stable, and sturdier than my previous one. The torque sensor is a game-changer! As a disabled veteran, my legs don’t work as well as I’d like them to. I could go to level 3 for short bursts before the pedals were too fast. The torque sensor on the ASYNC L5 makes for such an enjoyable ride—it's night and day compared to my old bike! Job well done, ASYNC!

H
Henry Huynh

First wknd having my L3 e-bike and I’m loving it! This is our 2nd e-bike from Async, we love their more edgy design esthetic approach. Very comfortable to ride, and the peddle to power response is fantastic. Customer service is excellent! Looking forward to many riding adventures!
