Why the BowTi might be the fatbike you’ve been looking for

How it rides

A fatbike naturally has a comfortable ride due to the large volume tyres, plus the supple feel of titanium. The geometry delivers on all fronts, tight flowy singletrack, or miles of open trails, the BowTi copes with it all.

One bike, more places

We are talk about a bike that does it all, where as most fall short in some respect but the BowTi is capable on any terrain, whether it be tarmac, gravel, rocks, snow, sand, roots, the BowTi takes everything in its stride.

Created from years of riding

After over 40 years of offroad riding I’ve developed a feel for what I think fits in the middle ground, a do it all bike, that goes where traditional bikes will come unstuck.

I first through a leg over a Fatbike in 2013 and what a revelation it was. Could this be the bike that does it all. So the journey began with my first bike, the aluminium Henderson. As time went on I wanted to offer custom options plus a frame that will last a lifetime so titanium ticked all the boxes.

Why titanium?

Titanium is the dream material.

No corrosion. No paint to worry about. Just a clean, raw finish that lasts.

It’s naturally compliant, taking the edge off rough ground while still being strong and lightweight.

This isn’t a bike for a season.
It’s a bike for life — one you build memories on.

Who it’s for?

Anyone who loves riding offroad and isn’t necessarily looking to take on the most extreme end of riding, it’s a mountain bike with extra’s. A true ATB, (All Terrain Bike). A proper adventure bike.

Why choose Smokestone?

Because you’re dealing directly with me.

Every frame is personal. I care about what I build, and I care about the person it’s for.

From the first message to the day you collect your frame — or your bike — it’s just you and me.

Most customers end up feeling more like friends.
And that’s exactly how I like it.

“The bike was excellent, very comfortable and i was extremely pleased with it. Same with the wheels, i had my doubts about carbon fibre rims, but i think they made quite a difference on the climbs paired with the relatively light Jumbo jim tyres.”

BowTi Journeys

Andy Deacon took his BowTi to the toughest BikePacking event in the UK, GBDURO, which is a self-supported 2000k ride from Lands End to John O’Groat offroad, coming home in 4th.

And just to prove the BowTi’s versatility Andy took on a road time-trial.

Kim Foster has been taking on as many challenges as he can since collecting his BowTi.

So far he has completed the Altravesur bikepacking route in Spain.

A grand tour of the Scottish Highlands.

FatViking in Norway and the Cold Ride in Canada.

And more recently a 200 mile loop around the English Welsh Border.

  • Built for Adventure

    The BowTi is designed to handle anything from daily errands to off-grid adventures. With rear rack mounts fitted as standard, you can easily carry your shopping or load up for a trip to the hills with your camping gear—and, of course, a few beers.

    Plenty of Storage

    For those long rides, the frame includes two bottle cage mounts plus a 3 bolt cargo cage mount under the downtube, giving you extra capacity to wherever the trail takes you.

    Cable Routing

    The BowTi features guided internal cable routing, making maintenance quick and easy. This system also includes dropper post routing, so you can upgrade your ride without the headache. Should you prefer external routing, no problem, we can do this also.

    Future-Ready Drivetrain

    Equipped with a UDH (Universal Derailleur Hanger), the BowTi gives you the flexibility to run a traditional drivetrain or go completely cable-free if you prefer a wireless setup.

    More Clearance, More Confidence

    The BowTi retains its signature curved top tube, providing increased standover clearance—perfect for those moments when "Emergency Clearance" is absolutely necessary!

    Wherever your next ride takes you, the BowTi is ready. text goes here
