Not so much though from Defiant Bicycle, which recently launched its first electric FAT bike known as The Big Easy. For those unfamiliar with the biking jargon, FAT bikes are so called this because they sport over-sized tires and are designed for riding on unstable terrain. The designers behind Big Easy sought to make an electric version of the FAT design as they wanted to bring to market something which could zip through snow and slush at 15 to 20 miles per hour. The Big Easy sports a number of features designed to make it an interesting example of electrification of this biking segment. These include a custom designed 6061 aluminum frame, a 500 watt electric rear hub motor, a 36 volt/15 Ah battery mounted within the frame triangle for optimal weight balance and a 4.7? “Big Fat Larry Tire.” This latter item is said to be the widest available in any bicycle. This first Defiant offering took over two years to develop and is domestically made. Its electric assist motor and battery can help offer a range of 25 to 65 miles, depending upon wind, terrain, temperature conditions and level of assist needed. It can be recharged at a standard wall outlet, and offers a top speed of 20 miles per hour. Designed to let riders go deep into the outback, specific build accessories and components help drive what it will be used for. This currently translates into five different configurations (including, yes, a gun holster as per the image above), ranging in price from $3,950 to $4,750. All of these can be pre-ordered before September, and the company is currently conducting a crowdfunding campaign to help kick things off.

These two trends converge in Defiant Bicycles' Big Easy. Unlike other electric bikes that stop at the edge of the street, the Big Easy keeps rolling over some of the toughest, most sluggish terrain on Earth – everything from hot sand to cold, mushy snow. We've seen a few different electric fat bike designs in recent years, including 20-inch-tired clown bikes from Hanebrink and the Pedego Trail Tracker. We expect to see more of these bikes emerge because many US cities with big bike cultures – Portland, New York, Boulder and Minneapolis, to name a few – can have harsh, snowy winters. An electric bike designed to excel in snowy weather seems like a natural fit for commuters in these types of locations. In fact, the Big Easy was created by a dedicated Minnesota cyclist to fill just that type of niche. Defiant co-founder Kevin Spreng, a Twin City-area attorney, became frustrated by the lack of viable winter commuters so he set out to design his own. "I thought I’d give a fat tire snow bike a try," Spreng explains on Defiant's CrowdSupply campaign. "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." With its 4.7-inch tires, the Big Easy is among the "fattest" of the fat bikes on the market. Those fat tires can be deflated to pressures as low as 7 psi, increasing their surface area to better "float" through soft terrain. Big, cushy tires also add a sort of suspension system, smoothing out bumps and ruts. While its burly build and big tires are all about rough weather, its e-assisted drivetrain is aimed at sure-footed, reliable commuting. Electric bikes like the Pedego Trail Tracker make riders choose between motored propulsion and pedaling, but the Big Easy uses a pedal-assisted powertrain that provides an extra boost to get riders from point A to point B a little faster, with a little less effort. Motor assistance can also be useful for carrying heavy gear or helping the rider muscle through a particularly tough, sticky track of snow. The drivetrain combines a 500-watt rear hub motor and frame-mounted 36-volt lithium-ion battery, offering enough power for 20 miles (32 km) of range and 20 mph of speed. The pedal-assist motor output can be adjusted at the push of a button. The rider can also pedal the bike without any motor assistance and has nine speeds at his disposal. The 8.5-lb (3.9-kg) battery, which takes about four to five hours to charge to full, can be removed completely to create a lighter set-up. A fat e-bike may be most at home in the slush or sand, but Defiant's idea was to build a bike that could excel all year, in all types of conditions, not just in the winter or on the sand. It claims the bike is a year-round workhorse and recreational steed for mountain biking and commuting. It's also marketing the bike at hunters, adventure tourers and other cyclists that cover a lot of ground with an abundance of gear. Defiant is currently trying to raise funds on crowd-sourcing site CrowdSupply.com. A Big Easy with a 6061 aluminum frame (built in Portland, Oregon), Shimano XT components and disc brakes is being offered for US$4,495. That's well over the price of the Trail Tracker but competitive with a Surly Moonlander outfitted with a comparable electric motor system. Other Defiant models are available for preorder on the company's website.
