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.

Great buy, good quality and really nice results!
Color: Dark, Color: Dark
I really like how silk and smooth this tanner feels! It’s not sticky tacky goop like some other brands can be and it’s really effective. Applying it went well as the product isn’t too thick or too thin, so making an even coat wasn’t an issue. It has a dark green tint which makes the product give its deep rich glow which is good for some medium toned to darker tone flesh colors. The effect is as though you’ve been in the sun deep in the tropics near the equator getting a daily golden caramel baked glow from some strong sun rays for a couple weeks. Works great and could be used for other than face in a pinch if needed...though you’ll probably want to buy a bigger bottle first because you’ll love it!!

Works great - don't let the dark color freak you out
Color: Dark
I am a reasonably fair skinned Caucasian person whose body can become moderately tan but my face does not, just burns and freckles. I don't tan my face at all and require a self tanner that makes my face color match my body. I have tried many expensive ones, and this is the best and most reasonably priced I have found. The stain works almost immediately and dries quickly so you have to work fast to smooth it evenly over your face. I skip the step of wearing a glove to apply and wash my hands immediately afterward but usually have to scrub with a wash cloth to get the color off. if you wait several minutes, you can add another layer to deepen the color (wash hands in between layers) but I use a generous amount with the first application so I usually don't have to. Most of the other facial self tanners I have tried have not been dark enough, even with multiple applications. This gives you a noticeable tan with just one application. Warning: it comes out of the bottle very alarmingly dark but it won't be dark like that after you apply it.

Great face self tanner
Color: Dark, Color: Dark
I only gave 4 stars because the Dark wasn’t that dark so the product isn’t very pigmented In a sense that’s good so you don’t go too over board but for someone who’s very fair and wants to get a dark tan it’s probably be difficult I love the smell, I was parried it would smell funny, the loving tan kind of smells like Dirt and this one smells like flowers and sweets. Not sticky and fast drying so I think it’s good for the face

Works fast and looks natural
Color: Dark
I have used a lot of facial tanners, and this one is a winner, by far the best I've tried. After only 3 applications, I see a definite difference in my skin tone. The color looks like a natural, sun-acquired tan. You only need a little, easily applied with the gloves that come with your order. I put it on at night before bed and let it dry. Protect your pillow though, as some of the tint rubs off. I really like this tanner.

Not as dark as a need for my pale complexion
I gave this product three stars because I don't think it is dark enough. You need to put it on daily and thick to keep color, if you have a pale complexion. However, the lotion does not make me break out, is a quality tanner, was affordable, and was shipped fast.
