And a smart, interchangeable rack and rail system lets you pick and choose from dozens of possible configurations to suit the mission. Capability meets versatility to make the Boost E the choice of professional rescue teams, adventurists, bike couriers and everyday suburban explorers. Benno performed a simple test at home and placed his car keys next to his bike lock. Anytime he left his house he had to choose between the two and if he picked up the car keys he had to justify why he was choosing to drive rather than ride his bike. This is how he discovered a list of objections that lead people to choose driving over cycling. The Boost is the bike Benno designed to overcome common objections to using our bikes more often. Take a ride on this Bosch equipped electric bike and you’ll understand why “too hilly”, “too far”, “I don’t want to get sweaty” and “I can’t carry enough” are no longer good reasons to leave your bike at home. The Boost will have you looking for excuses to go on additional errands. This compact and extremely sturdy e-utility bike makes transportation fun and easy. It’s designed to carry heavy loads and has an interchangeable rack system that you can pick and choose from to fit your needs. The strong frame and big tires are the perfect pairing for the powerful Bosch motor. People describe the feeling of riding with Bosch’s leading e-bike mid-drive system like suddenly having super-powers. Benno likes to call it the Boost. - Supernova V6s Light System (not shown)

If you can characterize your life as on-the-go, busy, or not having enough time, we made a bike for you—the Turbo Vado 3.0. It's made to accommodate busy lives that are always in movement, which is why we took our award-winning pedal-assist technology and accelerated it well into the future. Beginning with the integrated Specialized 1.2 E motor, the Turbo Vado proves itself as the ultimate city bike. The 1.2 E uses the same hardware as our 1.2 motor, but it features a tune that prioritizes efficiency. This means less peak torque and maximum output. Of course, it still features a near-silent operating design with our Custom Rx Street Tune that takes the output and makes it the most usable for an urban environment. Think of it this way: The more power you put out, the more power the motor puts out, and this makes accelerations from a standstill at, say, a traffic light both quick and efficient. The belt driven motor is also smooth, silent, and free of annoying vibrations. For the Vado 3.0, we developed a custom Specialized U1-460 battery that seamlessly integrates into the frame, is lockable, and easily removable for simplified charging. In other words, there's plenty of juice to take you to and from work, a trip to the grocery store, or even to that new cafe on the other side of the city. If you wish to see exactly how far you can go on a charge, have a look at our Turbo Range Calculator for more exact estimates. The new wired Turbo Connect Display (TCD-w) is the best way to view data on your Turbo. It not only displays important ride metrics (speed, cadence, rider power, distance, battery level, time, etc.), it also allows you to connect the latest version of the Mission Control App for an enhanced Turbo experience. With our free app for iOS and Android phones, you easily customize motor parameters, control your range, record/upload rides, and perform basic system diagnosis. To top off all of the innovative features, we chose a worry-free spec that features Shimano 9-speed components, hydraulic disc brakes, front/rear lights, and fender & rack mounts. - The Turbo Vado features a lightweight alloy frame that’s been designed with our Fitness/Transportation Geometry. - The Turbo Vado’s Specialized 1.2 E motor emphasizes efficiency and range. We also fully integrated it with the frame, and it's been custom-tuned for city riding. It intuitively reacts to the force of your pedaling, so the harder you pedal, the more power it delivers. And with an internal belt drive design, it does this without added vibration for the smoothest and most silent ride possible. - We made the custom 460 Wh battery to be fully integrated with the frame, removable for easy charging, and lockable for added security. It communicates with the display and has multiple modes to maximize the overall efficiency and range. For range estimates based upon a variety of variables, please refer to our Turbo Range Calculator.

It's cool to go fast, but it's only fun if you're comfortable. Sadly, speed and comfort rarely come together, but the Turbo Como 3.0 650b is out to change that.

Over the years, Surly has been finding new and better ways to haul stuff on the front of their bikes — from fork braze-ons to racks to bags. The Pack Rat is the culmination of all those years and is specifically designed around porteur-style racks and front-loading optimization. Why would someone want to strap a bunch of crap to the front of their bike? Glad you asked. Having your stuff in front of you means it’s close at hand and easily accessible. It also allows for better weight distribution. We’ve all ridden with a pannier full of groceries. Some of us have wiped out around a sketchy corner and watched as our precious eggs and bananas go flying every which way in an act of Mario Kart-level carnage. A front load keeps the bike nimble and allows you to more efficiently use your body English to steer from the rear and avoid such a super market massacre. The drawback with front-loading on a lot of bikes, however, lies in how it affects the bike’s handling. The weight pulls you through turns in an awkward sort of way as if the load is doing the steering and you don’t even have control over your own life anymore. It makes for an overall less enjoyable ride. The Pack Rat’s front cargo-specific design eliminates that steering issues but also rides great without cargo. There’s no need to load it down with cans of beans every time you want to go for a ride. Unless that’s your thing. We’re not here to tell you how to live. In an effort to jumpstart your front cargo carrying dreams, Surly includes a 24-pack rack on the complete bike version. The Pack Rat rolls on 26” wheels in the smaller sizes and 650b wheels in the larger ones. Smaller diameter wheels keep the weight of the load lower than a 700c wheel would, thereby improving handling and ride feel. Pack Rat’s fork also includes some handy internal routing for generator hubs so you can safely ride off into the night. Dedicated commuters, credit card tourers, those who enjoy the occasional sub-24 campout, and sweaty back people looking to leave their backpack behind need look no further than the Pack Rat.

Big Dummy is a long-tail cargo bike, which means that not only can you haul a serious amount of cargo, different accessories can be added to your Big Dummy frame and deck depending on what you want to carry. Being a dedicated single-piece frame, instead of an add-on to an existing bike, it's stiffer and resistant to torsional flex, which provides a better ride and longer lasting frame than long-tail add-ons. Like all Surly's frames, it's made of their size specific, 4130 CroMoly steel – a tube set engineered for cargo that sports lots of little touches that you've come to love in a Surly, like clearance for big tires and the use of common component sizes. Figure on being able to carry about 200 pounds (90kg) of cargo. The load weight, and how it's loaded, will affect the handling somewhat. Also, plan on using gears, especially as cargo weight increases. This may seem obvious, but as you get comfy with it, you will use your full range of gears as never before. The parts kit is good quality, and suitable to loaded as well as unloaded riding. It's got a 3x10 drivetrain, Avid BB7 disc brakes, quality Shimano Deore hubs, and 26x2.3" Kenda Kiniption tires. They've outfitted it with Surly-designed bags, deck, rails and Dummy Rail Collars; everything you need for the majority of stuff you might carry, like groceries, shovels, bags of charcoal or mulch, guitars, lamps, mannequins, whatever. Bags, deck, rails, and rail collars are all designed to improve on previous offerings and work together to make sure your stuff is transported with safety and stability. It's an unbending interface, which when you're carrying lots of cargo, is a good thing to have. Get creative, and get hauling. If you intend to carry a passenger on your Big Dummy, Surly requires use of their Dummy Rail Collars. These provide a secondary retention system for the rack, as well as stiffen the rack system. These are included with current Big Dummy bikes and frames, as well as available for older Big Dummy bikes and frames (compatible with all generations of Big Dummy bikes/frames). In addition, a stoker handlebar set up, found on tandem bicycles, is recommended as well. Make sure to check with seat post manufacturer for stoker handlebar compatibility. If you are planning to carry a child on your Big Dummy, Surly recommends the use of a child seat. They've tested the Maxxi Yepp seat. Yepp makes an adaptor that allows their seat to mount onto Surly's deck. It works well with the Big Dummy. At this time other child seats are not recommended and will void your warranty. Surly is testing other options. For the most up to date compatibility/options, check http://www.surlybikes.com/safety Note: keep in mind Big Dummy weight limits when carrying a passenger.

The Big Fat Dummy is a long tail cargo bike that took a few too many doses of growth hormones. At first glance, you might say that Surly just put bigger tires on a Big Dummy. But if you said that, you'd actually be very wrong so just… don't. Think of Big Fat Dummy as more of a second or third cousin to Big Dummy rather than a brother. They share some of the same DNA and look sort of similar, but they're two very different bikes and really only interact when they both reach for the potato salad spoon at that family reunion that no one really wants to be at anyway. Now that that's out of the way, let's get down to the nitty gritty of what makes this hulking beast of a bike tick. Surly's goal with designing a cargo bike around fat tires was to create the most stable, stiff, and traction-laden ride possible while hauling a ton of stuff. Big Fat Dummy has a longer toptube and slacker headtube than its more svelt cousin giving it a nice, predictable, and stable ride. They also used thinner, lighter tubing to construct its cargo area so while it's an overall burlier bike, there's not much difference in weight. Big Fat Dummy accepts either 10mm or 12mm axles in the rear with a spacing of 190/197mm. That big ol' spacing equates to one thing: tire clearance for days. Big Fat Dummy maxes out at a massive 26 x 5.25" tire.* While that large of a tire provides the most traction and stability a bike can possibly offer, it's also a lot of rubber to push and might not be for everybody. Luckily, Big Fat Dummy is also a blast to ride with 3" tires too. It uses the same 100mm suspension-corrected fork as the Wednesday, meaning if you want to add a little squishy squishy to your ride, you can throw a Bluto on and let ‘er rip. If you intend to carry a passenger on your Big Fat Dummy, Surly requires use of their Dummy Rail Collars. These provide a secondary retention system for the rack, as well as stiffen the rack system. In addition, a stoker handlebar set up, found on tandem bicycles, is recommended as well. Make sure to check with seat post manufacturer for stoker handlebar compatibility. All Big Fat Dummy framesets and bikes ship with a Dummy deck, rails, bags, and the aforementioned Dummy Rail Collars so you can immediately start hauling cargo — human or otherwise. Big Fat Dummy is ready and willing to carry all sorts of crap — literally. It's already in use on an organic farm in Ecuador so it's likely that it's hauled some form of manure by now. *Using a 26 x 5.25" tire will cause some drivetrain limitations.
