A fat-tire electric bike to take you through snow, sand, and the urban jungle.

The Defiant Bicycles Big Easy is a first of its kind: a hand-crafted, electric FAT bike that’s Made in the USA. The Defiant is the culmination of over two years of development and is the perfect choice for utility and recreation in virtually any setting.

Product Background

The inspiration for the Defiant came from company founder Kevin Spreng’s frustration at the lack of appropriate winter bikes. An attorney and committed bike commuter from the Twin Cities, Kevin wanted a bike that he could ride to work and for fun year round, through the harshest Minnesota winters. There simply wasn’t anything on the market capable of getting him through the snow and slush that made riding a challenge for as many as 6 months a year in Minnesota.

Electrifying a FAT Ride

“I thought I’d give a fat tire snow bike a try,” Spreng explains. “It worked great on snow and ice, but it wasn’t fast enough for me. So, I put an electric motor on my snow bike. It was brilliant. Now I could go 15 to 20 miles per hour on snow-covered trails and roads while still getting a terrific workout. That’s really how Defiant Bicycles and the Big Easy model were born.”

Building the Team

Looking to capitalize on the success of his prototype, Spreng teamed up with Jonathan Dombek and Greg Heinemann to develop Defiant, the company, and build its first model, the Defiant: an electric bike (e-bike) with the styling and craftsmanship one would expect to find in a top-dollar bike. Named, the Big Easy, Defiant’s first model has will fit and/or exceed the needs of several riding styles. As a FAT bike, it can go anywhere in as a commuter, snow, sand or rocky trail mountain-bike. It’s also perfect for the adventure-sportsman looking to get to a deer stand or previously unattainable location with a stealthily quiet mode of transportation.

The Big Easy Combines the Versatility of a FAT Bike with the Performance of an Electric Assist Motor

FAT bikes rule. Ask anyone who’s had a chance to ride one and you’ll see their eyes widen with glee. For the past five years, the FAT bike market has exploded in the United States and elsewhere. Enthusiasts have been blown away by FAT bikes’ ability to conquer terrain previously thought impassable by bike. Snow, rocky riverbeds, extreme off-camber sections, the steepest hills imaginable. A 4.7 in wide tire makes all of these scenarios rideable. FAT bikes were initially used on trails under many feet of snow. People were naturally curious, “I wonder how this bike would ride here, and here, and here?” Since their inception, FAT bikes have become the bike of choice for an immense cult of riders. Some people have gone as far as selling every other bike they own and opting to ride their FAT bike exclusively.

"You mean those tires won’t slow me down?"

While the FAT bike tires may appear slow and cumbersome, nothing could be further from reality. Though they are certainly wider, and larger, than traditional 26” tires, FAT bike tires float over most surfaces and keep the bike’s steering lively and assuring. Depending on rider weight, FAT Tires can be inflated to pressures as low as 7pounds per square inch. Lower PSI is how you unlock the performance advantage of FAT tires. This larger tire coupled with lower-than-normal PSI inflation also serves a dual purpose: natural suspension. Over bumps, rocks, You’ll feel like you’re riding a cushy full-suspension bike, only it’s faster and more responsive. FAT tires allow the rider to sling shot themselves through the nastiest bumps in terrain. They also ride fantastically on road. You’ll feel like you’re cornering on a motorcycle as you lean into turns on a descent at high-speed.

As a result, nowadays, FAT bikes are so much more than snow bikes. From winter riding, to desert sand dune sessions, to long-distance adventure touring, not to mention plain old-fashioned trail riding on your favorite patch of single-track, FAT bikes are showing up everywhere. FAT bikes are currently the fastest growing segment in the bicycling industry. Companies can’t make enough of them to keep in stock. That’s why we’re so excited about this opportunity. We wanted our first bike to make a splash, and what better way to do it than with the introduction of a Made in the USA electric FAT Bike?

Why Electric Assist?

Sometimes you need an extra boost. Sometimes you have to get from point a to point b faster than normal. Sometimes you have to blast through a snow bank. Maybe you’re hauling a lot of hunting gear in the wilderness. Whatever your reason, the Big Easy’s 500 watt motor will give you that extra boost to get you where you need to go, no matter the situation.

500 Watts of Unstoppable Power

As a means of making our Defiant more versatile than ever, we equipped it with a 500 watt electric motor. This allows you to carry more with you on a long commute, adventurous tour, or hunting expedition in all conditions. The electric assist also means that your bike has become more utilitarian than ever. Single-occupant trips by car become less necessary, which will save you money in the long run all the while allowing you to burn calories you wouldn’t if you made small trips by car.

Market Opportunity in the United States

With a range of 20+ miles, the Big Easy is positioned to put e-bikes on the map in the US where approximately 100,000 were sold in 2012. This figure lags behind sales in Europe where 1.1 million e-bikes were sold last year and in China, where approximately 27Million were sold in the same period! The Big Easy hits the fastest growing segments of the bicycle market – the electric category and fat tire category. With trends of electric car sales continuing to grow in the US as well as the use of bicycles for commuting in general, Defiant is positioned to take advantage of these macro trends with its introductory model – the Big Easy.

No License Required

Unlike motorcycles or scooters, the Big Easy doesn’t uses any fossil-fuels, is easily recharged at a standard electric outlet and is light enough to be rolled into the garage or shed or carried up stairs to an apartment or dorm room. Totally green. Completely efficient with a maximum speed of 20 miles per hour, it provides a comfortable commute, an edgy, all-conditions sporting experience and a daily workout for its user on a bike design totally unique to the category.

Where is the Big Easy Manufactured?

The Big Easy’s custom designed aluminum frame is manufactured right here in the United States.
