🛑 Hydraulic Disc Brakes

Brushless Powertrain & Intelligent Pedal Assist

The 48V 500W brushless rear hub motor delivers consistent torque across varied gradients. With a top speed of 30–50 km/h (approx. 18.6–31 mph), the motor control unit modulates output seamlessly, whether you rely on the throttle or the responsive pedal‑assist sensor. The integrated 12.5Ah lithium battery uses high‑density cells to balance weight and endurance.

Sustained Torque Output

500W nominal power with peak efficiency tuned for both stop‑and‑go traffic and steady cruising. The brushless design reduces maintenance and extends motor life.

12.5Ah Lithium Battery

Samsung/LG-grade cells in a compact downtube pack. Full charge in 5–6 hours, delivering 40–50 miles (64–80 km) depending on assist level and terrain.

Lightweight Alloy Frame & One‑Step Folding

The 20‑inch frame is crafted from 6061 aluminum alloy, achieving a optimal strength‑to‑weight ratio. The patented step‑through design (E‑FAT‑STEP) allows easy mounting, while the centralized hinge lets you fold the bike in under 10 seconds for storage in compact spaces — car trunks, closets, or RV compartments.

Shimano 7‑Speed Drivetrain & KENDA Fat Tires

Equipped with a Shimano Tourney 7‑speed rear derailleur and a responsive thumb shifter, the HKM‑305235 adapts instantly to changing inclines. The 20" x 4.0" KENDA/CHAOYANG sport tires provide exceptional floatation on sand, snow, and gravel, while maintaining low rolling resistance on pavement. Black alloy double‑wall rims add durability without excess weight.

Frequently Asked Questions

What is the real‑world range on throttle only?

On flat terrain with minimal wind, throttle‑only operation typically yields 25–32 miles (40–51 km). Using pedal assist extends range significantly, up to 50 miles.

How does the folding mechanism secure during transport?

The main hinge incorporates a stainless steel locking pin and a secondary safety clamp. Once folded, the bike remains compact and stable for lifting into vehicles.

Can the battery be charged on or off the bike?

Yes, the 12.5Ah pack is removable and can be charged indoors or while mounted on the frame. A full charge takes approximately 5–6 hours.

What maintenance do hydraulic brakes require?

Mineral oil systems rarely need bleeding. Inspect pads every 300 miles (480 km) and keep rotors clean for optimal performance.

Possible solution to seperation
Style: Restorative Protective Cream-1.3 Fl Oz
I love this product so much, but, like everyone else the water HEAVILY separated. A lot of water just shot out immediately and as i've used the cream it has felt more and more thick bc of that, shaking the tube or not. POSSIBLE SOLUTION: I actually think the company could salvage this problem by upgrading packaging to a Cosmetic JAR and then customers could take a toothpick and stir if separation has occurred by the time of purchase. I hope to try this with my next tube, just toothpaste squeezed everything out into a nice cosmetic jar and stir the water back into the product. This is such a simple solution that could really solve the product waste. This refreshes my skin, doesn't break me out, and is lovely. I break out so easily, and being middle aged my skin really requires a dense help with moisture. <3

Ordered in spring/summer and it arrived separated too BUT...
Style: Restorative Protective Cream-1.3 Fl Oz
Ok, So I heard great things about this cream and decided to order. I ordered on May 28th and I live on the Gulf Coast of Texas and it is in the low 90s right now. I was worried mine would arrived separated like many others claimed to have gotten theirs, and sadly it did. Warm weather or not, blue water shot out of the tube the minute I squeezed it. Luckily, I read Mia P's review and submerged my tube in warm water (hot water actually straight out of my instant hot water faucet). I left it for about 5 minutes then shook it vigoroously. It seemed to help but was still a bit wonky so I repeated the process again and success! My tube is totally fine now and comes out in a thick, rich, emollient cream as it is supposed to. I will update my review after I use it more but so far I love the way it feels on the skin. It is very thick but spreads nicely and completely absorbs into the skin and leaves no greasy residue which is a big deal because I have oily skin. I purchased this to help with my Retin A uglies (I actually am using Musely with .05% tretinoin) and am hoping it helps with the redness and peeling I am having. I will update my review once I've used it for a while but wanted to post this review as I saw so many people complaining about the separating and just thought I'd mention that you can fix this issue if you have it (and there is a good likely hood that you will). Update: I've been using this for a week now and I am absolutely in love with this cream! It is the most hydrating and healing cream I've ever used. Usually, thicker face creams like this would cause issues for me with acne or clogged pores as I do have oily skin that can break out if I use products with occlusive ingredients, but this one does not. In fact, my skin has never looked better! This is a must-have if you are using Retin-A/Tretinoin and going through the red/peely phase with your skin. The separation that occurred when I first received it has not been a problem and the cream is staying thick and free from any strange liquidy issues after I put it in hot water as mentioned in the first part of my review.

Saved My Skin and Healed My Eczema
Style: Restorative Protective Cream-1.3 Fl Oz, Style: Restorative Protective Cream-1.3 Fl Oz
I was having the worst skin winter of my life. I am hypersensitive and my skin started rejecting an expensive line I had used for many years (EL). My skin wasn’t healing even just using AQ balm on it and occasionally steroids when it was extra bad, and the pronounced eczema on my eyelids and neck for months was making me miserable and gross looking. I started researching brands I hadn’t tried for super sensitive skin and saw recommendations for Avene. We were leaving on a vacation and I was desperate to feel better so I ordered this and the matching serum. I started with only this cream and overnight I saw my skin start to heal. Within a few days it was like the last few months never happened. I carefully added the serum and had no issues. I used only these two products for the month I was gone and had glowing skin the whole time. This is thicker than a normal lotion since it is made to protect your skin but if you let it warm up a few seconds it smoothes easily. This will definitely remain a staple in my skin arsenal and I can’t thank you enough for making an actually gentle but effective product! This picture is two weeks after starting the product, smooth skin and confident to take selfies!

Don’t let the bad reviews deter you from saving your skin
Style: Restorative Protective Cream-3.3 Fl Oz, Style: Restorative Protective Cream-3.3 Fl Oz
I avoided purchasing this product for a while due to the bad reviews. However, it is still highly recommended by several dermatologist for skin barrier repair. Upon doing my own research, the product can separate if it is stored in cold temperatures (41 degrees or less). This can be fixed people!! It literally says it on the bottle/box and there’s even a video that Amazon posted saying this can happen. It does not affect the product. It’s just the thermal spring water and some oil separating but it can be reincorporated. So I took the risk and ordered this. I’m a first time purchaser. It was already at my door when I was leaving for the gym at 5:30am so I let the package sit in my car for about 1.5 hours (temp was about 70s). I put the tube in a glass of hot sink water for 10 minutes when I got home. I rolled the tube in my hands for a few minutes to mix everything together. Guess what. It came out like a CREAM. No liquid shot out at me. If you can read, do a little research, and can follow instructions, you can get a working product. I have sensitive skin. It’s been a struggle healing my skin barrier but it was getting better. I decided to do something dumb and try dermaplaning. My cheeks have been very red and irritated since. I did avoid active products for a few days after dermaplaning but it was still irritated. Just with the first time use of this product, it was nearly instant relief of some of the redness. It’s fragrance less which is great. It is currently on sale so I think the value is good for what it is right now. I only used two pea-sized amount for my whole face so I think it will last awhile. This can significantly help your skin barrier! Do your own research and read the instructions!

Samples great, purchased product not
Style: Restorative Protective Cream-1.3 Fl Oz
My dermatologist recommended this cream after a laser procedure, and gave me some samples to take home. I found the thick, smooth cream calming and protective for my irritated skin. The zinc oxide leaves a whitish cast at first, which does tend to fade after it sinks in, but it could be problem if you have darker skin. Not an issue for me since I’m pale. Because I liked the samples, I ordered two full-size tubes. Both arrived with the product inside completely separated. The texture was nothing like the samples. I opened the first tube and clear, watery liquid spilled everywhere. I quickly recapped it, shook and squeezed the tube as much as possible to try to re-emulsify the product, and it remained stubbornly separated, with chunky white paste suspended in thin liquid. I’ve thoroughly shaken the second tube and continue to hear the sloshing of thin liquid. So apparently once the cream has separated, it will not re-mix. I don’t know what caused the unacceptable condition of the product—manufacturing variation, storage conditions prior to shipping, or conditions during shipment. Whatever it was, I would not buy this product in this way again. The samples were a five star product. The full size product I received was zero stars.
