KOOLUX X12 Folding Electric Bike is built for the way you move today—fast, flexible, and perfectly tuned for urban living. This is the bike that packs power, portability, and practicality into one sleek ride, so you can switch from scooter to bike without a second thought and glide through the day with confidence.

Engineered for city life, the X12 folds down to a compact footprint that fits where space is precious—apartment closets, office corners, coffee shop corners, and even your car trunk. When you’re ready to roll, a smooth folding mechanism and secure latch ensure a stable ride every time, so you never feel like you’re compromising on balance or safety.

  • Portable folding design that reduces the bike to a storage-friendly size, making commuting, transit trips, and weekend getaways easier than ever.
  • Electric-assisted riding with intuitive pedal assist that adapts to your speed and terrain, giving you extra boost on hills and against headwinds while helping you conserve effort on flat, urban routes.
  • User-friendly cockpit with a clear built-in display that keeps track of speed, remaining range, and assist level, so you know exactly how far you can go on your next ride.
  • Responsive handling and a comfortable geometry designed for daily commuting, campus cruising, or spontaneous rides to the park.
  • Low-maintenance reliability from a durable frame and components chosen for urban use, so you spend less time tinkering and more time exploring.

Who is this for? The KOOLUX X12 is ideal for urban commuters who want a single ride that can seamlessly integrate with public transit, students who crave campus flexibility, and anyone who stores bikes in tight spaces but still desires a powerful electric assist for longer city trips. If you’ve ever felt restricted by bulky bikes or limited by transportation options, this folding e-bike opens up more routes and more possibilities—from quick errands to weekend adventures.

Why it matters – a folding electric bike like the X12 eliminates the need to choose between a car and a bike. It unlocks last-mile solutions, lets you bypass crowded racks, and reduces fatigue on daily commutes. The electric assist keeps your energy up for longer rides, while the folding feature ensures you can tuck your bike out of sight and bring it anywhere you go.

Practical tips to get the most from your KOOLUX X12:

  • Charge regularly and avoid letting the battery drain completely to extend overall life.
  • Keep tires properly inflated for a smoother ride and better efficiency.
  • Fold and store with care, ensuring the latch is secure before transit.
  • Choose a higher assist level for hilly routes, then switch to lower levels on flat segments to maximize range.
  • Regularly check brakes and drivetrain to maintain peak performance with minimal maintenance.

Make every journey smarter, cleaner, and more flexible with the KOOLUX X12 Folding Electric Bike. It’s more than a bike—it’s your portable urban mobility solution, ready to adapt as your plans do. Add it to your cart and redefine how you move through the city.

Great sock for everyday
Size: Large, Color: Black/Gray (6 Pairs)
So these are awesome but they are slightly thinner than older versions, shorter too. Just FYI if you a long time UA customer. If you have never had their socks, I love them personally and only like one other brand better. They aren’t overly thick and they allow your feet to breath. I never have sweaty feet in these even in my warm boots. I also like that they don’t cut into my feet or get holes in the toes over long terms. The only reason I’ve thrown these out has been fraying near the ankle or someone (kids) thieving them.

LOVE THEM!!
Size: Small, Color: (001) Black / Black / Castlerock
LOVE! These socks are so comfortable! I wear a 5 in women's and a 3 in big kid shoes. The small fit me perfectly. I see where some say they run small but I can't say that was an issue for me. They are "snug" but thats what you want with a no show sock. I feel they have support vs the ones i used to buy at Walmart. They are very soft! I am actually buying more today and throwing my other ones in the trash!

So will not write down your foot
Size: Medium, Color: (001) Black / Black / Castlerock
I love these socks. They have a little bit of gel on the top of the heel for support in your tennis shoes and so your socks don’t write down. Very good quality.

Comfy and Stay Put
Size: Medium, Color: (002) Black / Black / Halo Gray
These socks are honestly great. They’re super thin and light, so once you have them on, you kind of forget they’re even there. No bulky feeling in your shoes at all. The best part is they actually stay on. I hate no-show socks that slide down after five minutes, and these don’t do that. The little grip on the heel really works, so you’re not constantly adjusting them all day. They’re breathable too, which is nice if your feet run warm. They dry fast and don’t get that gross sweaty feeling. And there’s no annoying seam on the toe, so nothing rubs or feels uncomfortable. Basically, they’re just comfy, stay put, and don’t cause problems — which is all I want from socks.
