Intelligent Power & Range Architecture
The dual 52V packs work in parallel, monitored by a smart battery management system that optimizes discharge and charging cycles. Riders can expect up to 60+ miles (96+ km) using pedal-assist level 2. The removable design means you can charge one pack while riding with the other — effectively doubling daily range.
⚡ Regenerative-ready controller
The sine-wave controller supports regenerative braking assistance, recouping energy on descents.
🔋 Independent charging
Each 52V pack charges in 4-5 hours. Charge both simultaneously with optional dual charger.
20" x 4.0" Fat Tire Confidence
The 4-inch-wide CST fat tires (20" diameter) run at low pressure (5–30 PSI) to absorb chatter and float over sand, snow, and loose gravel. Combined with dual suspension, they dramatically reduce rider fatigue on long hauls.
Hydraulic Stopping Power
Front and rear hydraulic disc brakes with 180mm rotors provide consistent bite. The sealed system requires minimal maintenance and offers precise lever feel — essential when navigating technical singletrack or sudden urban stops.
Ergonomic Cockpit & Digital Display
The adjustable stem and seat post accommodate riders from 5'3" to 6'4" (160 cm–193 cm). The backlit LCD shows speed, battery percentage, odometer, and assist level. Control buttons are positioned for thumb access without removing hands from the grips.
Frequently Asked Questions
What is the actual range on throttle only?
On flat terrain with a 180 lb (82 kg) rider, expect approximately 35–40 miles (56–64 km) using throttle-only mode with both batteries.
How does the dual-battery system switch?
The controller draws from both packs in parallel automatically. You can also remove one battery and operate on a single pack.
Is the bike waterproof?
IP65-rated motor and battery connectors. Avoid submersion, but rain and splashes are well tolerated.

A PLACE FOR YOUR HEADSET
Size: Small Storage Area, Size: Small Storage Area
This holder is fantastic, if you have the steel series headset and extra batteries it's perfect you'll love it, but would like to see a white version as well.

Not quite right
Size: Small Storage Area
this is "as advertised" but
a simple extra ridge of plastic would have made it perfect.
the issue people are having with the arctis pro, the thing that makes you want a stand for it, is the base station is a little too light, you can push it when you go to use the knob's integrated button.
Issue here is the fit of the base is loose enough, you can still push the base out of the back. So it looks nice, and gives you a place to put the headphones and some other desk clutter, but it doesn't REALLY solve the problem.

3D Printed (Not Mentioned) and Base is Way Too Loose
Size: Small Storage Area, Size: Small Storage Area
I bought this to clean up my desk setup for my SteelSeries Nova Pro Wireless, and while it looks decent from a distance, there are two major issues that weren't clear from the product page.
First, this is a 3D-printed product. Nowhere in the Amazon description or photos does it state that this is 3D printed. You can clearly see the layer lines and "stair-stepping" on the curves. While I don't mind 3D printing in general, for this price point, I expected a standard injection-molded plastic finish. The product page feels a bit misleading by omitting this detail.
Second, the fit is very poor. The "integrated dock" for the GameDAC station doesn't actually lock into place. There is no snap or friction fit; it sits so loosely that you can slide the DAC out of the front or back with the single push of a finger. This makes it feel unstable, especially when you are trying to use the volume dial or swap out batteries.
Bottom Line: It’s a nice idea and fits the aesthetic of the headset, but the execution feels like a prototype rather than a finished consumer product. If you're looking for a secure "lock-in" feel for your expensive base station, this isn't it.

High quality stand
Style: Swivel Base, Color: Silver, Style: Swivel Base, Color: Silver
The mStand 360 is an amazing stand. I love how it is built from a single piece of aluminum and looks amazing on my desk. It fits my Macbook Pro 15" extremely well and raises it up to the height of my monitor easily. Not only does it help me improve my posture, but it also neatens up my desk significantly. I can easily fit an external keyboard under my Macbook when I am not using it, clearing up space. The hole in the back is also useful for bunching cables together that go directly into my Macbook, keeping my cables off the floor when I take my Macbook to go somewhere.
The stand feels very stable, with no chance of my Macbook falling off. The aluminum C shape does have a slight bend on it if you put extra weight on it, but all in all, it feels very sturdy. The rubber padding on the stand also keeps the stand from scraping or damaging any part of my laptop and I feel very comfortable trusting the stand with my laptop. I would not recommend typing on a laptop keyboard while it is on the stand, but it works great with external keyboards.
The swivel feature met my expectations, allowing the laptop to be easily turned. Thankfully, it was not too easy to turn and my laptop does not turn itself when in the stand. It is a nice feature to have, especially because I paid only 5$ extra for it (the price for the swivel stand seems to have increased since then).
I am very happy with my purchase, even though it did seem a little expensive. I am wholly satisfied that I spent the extra 20$ to get a great laptop stand that will probably last for years.

This stand is just perfect!
Style: Swivel Base, Color: Space Gray
I first started looking at stands when I learned that staring at a laptop for hours can cause back injuries.
So, I got the idea to use a stand, at home. This stand allows me to have a keyboard and mouse and use my laptop as a glorified desktop with a smaller monitor.
I was astonished at the quality of this stand. It is better built than it needs to be, but I am not complaining at all about this. Let's face it, we spend a lot of money on our laptops, and you want to have a great platform to sit your laptop on.
I love the ability to swivel the stand. My desk is very close to a window that lets in a lot of the sun at certain times of days. This would result in a glare if not for the ability to spin my computer ever so slightly in either direction to combat this problem.
Also, it is a great cable manager with the hole on the back of the stand that makes everything look cleaner and more organized. The color matches my MacBook perfectly and looks like it is an Apple product.
Summary:
Great product. High quality. Looks great. Swizel is impressive and useful.
