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.

Super Soft and Cozy Hoodies
Size: X-Large, Color: Black Heather Pullover, Size: X-Large, Color: Black Heather Pullover
Product: Eversoft Fleece Hoodie Brand: Fruit of the Loom Positives: Super soft and cozy. Light weight and really warm. Easy to pull over. The material is quality and for the cost is an extremely great value. There is an assortment of colors to choose from. Hoodies to go with everything. I am super happy with my purchase and the deal that I got. Negatives: Not super thick, but also fluff up a little after the first wash. Overall Impression: The hoodies look great and are a super good value. I use them daily and recommend them to anyone looking for a good hoodie that doesn’t cost a fortune. There are plenty of colors to choose from, to wear with anything for any occasion, at anytime.

Will buy more
Size: X-Large, Color: Black Pullover
This sweatshirt is a great basic that works for everyone. The fit is comfortable and true to size, but also looks good a little oversized if you prefer a looser style. The material is soft on the inside and warm without being too heavy. It’s perfect for men, women, and teens — super easy to layer or wear on its own. The quality is better than expected for a generic sweatshirt, and it’s held up really well after multiple washes with no shrinking or fading. Simple, cozy, and a great everyday sweatshirt for all sizes and genders!

Comfortable Everyday Hoodie
Size: Large, Color: Black Pullover
This hoodie is a great basic to have on hand. The fleece material is soft and comfortable, and it provides just the right amount of warmth for cooler mornings and evenings. The fit was true to size, and it held up well after washing without losing its shape. My husband likes wearing it for everyday errands, walks, and casual outings. It's comfortable, lightweight enough to layer, and easy to throw on when you need an extra layer. A solid, affordable hoodie for everyday wear.

solid basic hoodie - but please don't sew the draw string in Fruit of the Loom!!
Size: XX-Large, Color: Black Pullover
I love these hoodies and actually have a few of them in my wardrobe - I would give them a 5-star as they're very comfortable, hold-up well to wear and tear, and they're pretty warm... They don't shrink or bleed dye in the wash, great stuff. HOWEVER! They recently started sewing the drawstring in, which is really annoying... I wear the XXL size and the hood is still a bit small for my dome, so I typically don't need the drawstring, but now I can't remove it without trying to remove the stitching and damaging the hood or cutting the ends off, leaving most of them inside the hood - meaning you can't replace the drawstring should you want to (which sometimes I do, like if I'm skiing or what not)... I also work with power tools, which make loose ends like drawstrings outright dangerous, so I really need to be able to remove them easily - I would give these hoodies a 5-star if they stopped sewing the drawstring in
