Honey BiFröst Converter Titanium Bike


Honey BiFröst Converter Titanium Bike

The Honey Bifröst, pronounced /ˈbīfrôst/ or ‘byefrost,’ is a handmade titanium dual wheel offering designed specifically for the harshest environments of snow, sand, primitive trails, rocky and rooty terrain, and unknown territory. The BiFrost is ready for anything you’re up for, and then some.

The term, “Converter,” means that Honey designed this bike specifically for two very different types of wheels. This sounds simple but it’s actually rather challenging to optimize a bike design for two very wheel sizes and ride styles. The BiFrost comes with “fat” 26” x 4.8” wheels and “plus” 27.5” x 2.8” tires.

Why dual wheels? One of the unique aspects of the Honey BiFrost is how it handles both systems wheels perfectly. We can provide you a versatile bike that’s fast when plus and adventuresome when fat. Over the past decade Honey has figured out how to push frame design in new ways, so they can offer two bikes in one - and without limitation in either direction. This is a true four season bike with no compromise in any season!

Choosing the Titanium or Steel BiFröst

Honey offers the BiFrost in titanium only. All of their harsh weather bikes — those designed for snow, sleet, and other elements that rust steel — are exclusively available in titanium. While the up front investment is slightly higher, the total cost of ownership is significantly lower over a 5-year time-span.

Why is the Honey BiFröst Titanium the ideal fat tire AND plus tire bike?


While the BiFrost is somewhat unique in that it provides a balanced and fast right both fat and plus wheel sizes, we’d put BiFrost up against any pure fat or plus bike on the market. You really get two bikes in one. First is a super fun fat bike that can go anywhere at any time. Second is a fast and nimble plus bike that’s ready for any mountain bike trails and is nearly as fast as the best 29er race bike. How is this possible? We’ve been designing dual wheel bikes for nearly a decade and we’ve been riding fat and plus since the first tires were available. Some of Honey’s most popular bikes are the plus and fat.

When you’re riding the fat wheel setup you’ll never want to take them off. This setup can handle the toughest ride you throw at it. The titanium frame can match the harshest of conditions. Put studded tires on this machine and you’ll not come home until well after dark.

When you’re riding the plus wheel configuration you’ll be fast because the ride is so smooth and the tire contact patch is so large. It’s counter-intuitive that a bigger tire could feel as fast as a light 29er but Honey’s handpicked wheel systems are as light as they come and are still as durable as any wheel-system on the market. The plus setup is about as good of an all-rounder as you could ask for.

The BiFrost Converter Titanium is priced to provide you more value than any other titanium bike on the market. And titanium is the best material for this kind of riding. It's the lightest bike in its class compared to any bike with a matching parts kit. So, it is kind of the best of the best. times two.

Bike Fit & Geometry

  • 8 sizes to fit just about anyone. We make women's and men's bike setups, too.

  • 0.5” top tube length increments enable you to choose between a few frame sizes, to fine-tune your fit and comfort.

  • High and Tight: When compared to a typical mountain bike, the BiFrost geometry puts the rider slightly more upright, slightly shorter reach, and a slightly more forward center of gravity. All of these modifications provide:

    • A more comfortable position for adventure riding. We’re not winning races on this bike we’re winning the exploration and fun competitions.

    • A slightly more forward rider position give you more control of the front end. However, because of the large tires contact patch you still have fantastic tire traction at the rear of the bike. This creates an excellent gravity balance between the wheels.

    • The bigger and softer tires require better control of the bike. sitting slightly more forward improves front end control and reduces rider fatigue.

    • This progressive rider position also helps make the bike more nimble. The bike feels a lot easier to handle than a typcial fat bike. Some of this is due to rider position.

  • Winter Riding: While the BiFrost is a versatile bike that’s equally at home in the sand, loam, or craggy rocks of summer, we’ve ridden through many winters and have some strong opinions about what makes an ideal winter riding position. In short, you want a position that’s a bit shorter, more upright, and more open than at other times of the year. There are three primary reasons for this:

    • Winter clothing is much more restrictive than summer season riding gear. You’re layering. You’re wearing restrictive tights. You’re wearing big gloves and big boots. The entire sport becomes very different. This more restrictive clothing benefits from a more open rider position. By being less restricted you’ll have much more control of the bike and actually feel faster and safer.

    • Cold weather keeps you cold. Maybe it seems obvious. However, in the summer your body warms up and becomes much more flexible and limber. In cold winters your body takes a lot longer to settle in, or if it’s really cold won’t really settle in at all. The BiFrost fit works well in these conditions.

    • When you’re cold you can’t truly relax. Therefore you’re never 100% settled on the bike. A slightly more compact ride is easier and more comfortable to handle. You’ll be faster and more confident on descents and tight technical singletrack.

  • Optimized for varied terrain: The BiFrost is designed for rides on much more varied terrain than a typical fat bike or plus bike, so the rider position provides a slightly shorter reach and a slightly higher bar than a pure single purpose bike. This position also helps prevent lower back pain and protects your body better during long rides on the trail.

Handling & Performance

Bike geometry: With its stable front end, optimized trail, high bottom bracket, and long wheel base the BiFrost makes for a great adventure all-season ride.

  • Predictable and sure-footed handling through thoughtful frame geometry, tubeset selection, and component curation. Some of this is obvious and some of this runs very counter to popular current frame design fads.

    • Predictable because when you're not sure what's around the next corner on that snowy hidden trail, you want to know that the bike will do what you want it to do. Sometimes people confuse quick handling with predictable handling; in general, quick is not actually very helpful; predictable handling -- at all speeds and in all conditions -- is extremely helpful. And helps you ride faster.

    • Sure-footed because when you're in the fifth hour of a long adventure ride you don't want an overly quick or squirrely bike; that's exhausting to manage -- and a bit dangerous. This bike behavior will help you settle in and relax on the bike -- an important feature of an adventure bike.

  • Excellent tracking and traction: The Honey proprietary seatstay design and tubing provide improved traction and predictability on any decent and on any trail surface. The titanium BiFrost will help keep your tires connected to the trail. You'll be able to ride faster and more sure-footedly.

  • Excellent climbing ability: The BiFrost’s titanium frame tubing employs stiff chainstays for efficient power transfer to get you up the hills faster and with less effort. There is no stiffer titanium drivetrain available on a fat or plus bike.

  • Frame size-specific tubing: This ensures the best possible handling at the lowest possible frame weight. We selected each tube, with specificity, for each BiFrost frame size.
