Top quality batteries are the heart and soul of your FLUX bike, they're one of the things that make it so special. Not all ebike batteries are created equal, and we refuse to cheapen your experience with a battery that is anything less than awesome. 
How do we do it?
Let's take a quick walk through the magic factory. 
 
Meet The Match Maker
Relationships are short lived if partners aren’t right for each other, the same goes for lithium battery packs. To get the best performance and life, lithium battery cells need to be paired with other cells of the same characteristics. When new cells arrive, a technician programs The Match Maker and loads batteries into the hopper...
The matchmaker automatically tests and sorts the cells into groups of batteries that will reach ideal performance when bundled together.
Otto
Otto is a machine. He doesn’t complain, cut corners or even sleep. He has one job- to solder the most beautiful joints between battery cells that you’ve ever seen, and he's great at it. There are a lot of cheap ebike battery packs out there with less than impressive guts- we urge you to take them apart. We’ve seen ones with cells taped together, mismatched brands and cells that were taken from old power tools. Scary.
The Line
When Otto's finished, human technicians bring the batteries to the line for visual inspection. If everything is good, they will install the battery circuits and assemble into the final case. 
The Proving Grounds
The assembled battery packs are lined up to go head to head with a cycle tester in a grueling 72 hour final exam. They're continuously charged  and discharged at varying rates to test the capacity for different levels of performance. If the battery pack fails any of the tests, it is eliminated from the line-up.
Packing
The proven batteries are packaged, palletized and shipped to the factory to await oncoming adventures.

Frequently Asked Questions

Have a question? We've got answers.

What's the best commuter ebike?

For daily commuting, the Babymaker II Pro is our most popular pick. It weighs just 35 lbs — light enough to carry up stairs or onto transit — and its Gates Carbon Belt Drive means virtually zero maintenance. A single charge gets you 20–70+ miles depending on assist level.

If you want cargo capacity and a more upright position, the Moonrider is a great alternative with dual racks and a Bafang mid-drive motor that handles hills with ease.

What's the best lightweight ebike?

The Babymaker II is our lightest model at just 33 lbs — significantly lighter than most ebikes on the market. Its minimalist frame and compact battery keep the weight down without sacrificing range or performance. Perfect if you need to carry it up stairs or store it under a desk.

Do I need a license to ride a Superhuman ebike?

In most US states, no license, registration, or insurance is required to ride an ebike — as long as it meets federal ebike classification standards. Most Superhuman models meet these requirements. Rules vary by state and municipality, so we recommend checking your local laws, especially for Class 3 bikes on trails or shared paths.

What's a fat tire ebike?

Fat tire ebikes feature oversized tires — typically 4 inches wide or more. Those wide tires give you more traction on loose surfaces like sand, gravel, and snow, better shock absorption, and increased stability at low speeds or in technical terrain. Great for riders who want to go off the beaten path or ride year-round regardless of conditions.

If you're looking for the best fat tire electric bike for all-terrain riding, the Superhuman Bikes Bomber is our top pick. The Bomber is a 750W scrambler-style fat tire ebike built to go anywhere — sand, trails, dirt roads, or city streets. It runs on a 48V 17Ah battery with 40+ miles of range, 20-inch fat tires for maximum grip, hydraulic brakes, dual suspension, a comfortable bench seat, and optional foot pegs for a moto-inspired feel. Available in multiple colors and two configurations, it's one of the most capable and versatile fat tire ebikes on the market.

What's the best ebike for beginners?

We recommend the Moonrider or the Photon for riders new to ebikes.

The Moonrider has a step-through frame (easy to mount and dismount), an intuitive mid-drive motor, and comes with front and rear racks so you can start using it for real errands right away. Its Shimano 10-speed lets you gradually learn how to blend pedal assist with gear selection.

The Photon is a great option if you want something lighter with a throttle option, so you can start by letting the bike do the work and increase your own pedaling input as you get comfortable. It ships 95% pre-assembled — front wheel, pedals, and handlebars and you're ready to ride. (And they glow in the dark!)

How long does shipping take?

All in-stock Superhuman bikes ship within 3–7 business days of order confirmation. You'll receive a tracking number via email once your order leaves our warehouse. For the most current availability on specific models, check the product page or contact our support team.

What's the longest range ebike in your lineup?

The Weapon leads the lineup with 70+ miles of range on its 840Wh battery — the highest-capacity battery we offer. The F5 Trail also carries an 840Wh battery and delivers 50+ miles per charge under typical conditions.

Real-world range depends on rider weight, terrain, wind, temperature, and how much you pedal vs. rely on the motor. Using lower assist levels and pedaling more actively will always extend your range.
