Waheela S was designed from the ground up to be the most versatile gravel bike available. The first suspension-corrected gravel bike on the market, the
Waheela S can run a suspension or rigid fork. If you're riding terrain that requires suspension, you'll also need a frame with giant tire clearance. The Waheela S can fit up to 29" x 2.1" or 700c/650b x 53mm tires.

PEAK GEOMETRY™
Our Peak Geometry™ is the future of gravel. It centers the rider over the wheels for the perfect balance of speed and stability.
Comfort
The rider is perfectly balanced over the frame to boost performance and reduce fatigue, letting you ride faster and longer.
Confidence
The optimized body position produces a stable wheelbase that improves handling, across all surfaces and in any conditions.
Consistency
The same angles and proportions are maintained across frame sizes, giving every rider the same great experience.
SUSPENSION CORRECT
Waheela has a suspension corrected 420mm axle-to-crown fork and handles optimally with both rigid and gravel suspension forks.
REYNOLDS STEEL
Waheela S uses Reynolds 520 steel to produce a strong, light bike with a supple yet lively ride quality. The tubes also feature an electro-deposited (ED) coating inside and out for rust protection.
TUNING CHIP™
The patent pending Tuning Chip™ system provides 20mm of chainstay length and 4mm of bottom bracket height adjustment, allowing you to fine tune your ride.
AND SO MUCH MORE ...
TOP PERFORMER
Unparalleled ride quality results from the combination Reynolds 520 steel and carefully thought out frame geometry.
FORWARD THINKING
The increased reach of our RideForward design requires minimal changes to the head tube angle between sizes. This makes the geometry and handling more consistent between sizes while reducing to overlap on smaller frames.
RACE INSPIRED
Waheela features lower stacks for an improved fit and a slack seat tube angle for a race-friendly seat position with zero offset.
CLEARANCE FOR TAKE-OFF
Like the Warakin, Waheela has massive tire clearance and can be built up with tires ranging from all-road 700Cx28 through road-plus 650Cx53 to trail-ready 700Cx53 (29x2.1) for rough terrain.
HAVE RACKS? WILL TRAVEL
Numerous braze-ons allow Waheela to accommodate cable routing clamps, 3 water bottles, fenders, racks, frame bags, and more.
SHIFTY, BUT IN A GOOD WAY
Full-length cable housing provides flawless shifting in even the worst conditions.
HIP TO THE DROP
The Waheela frame is compatible with internal routing dropper seat posts.
QUALITY ASSURED
Designed by the Otso engineering team, Waheela frames are manufactured by one of the top steel frame fabricators in Taiwan and come with a five-year limited warranty. All bikes are inspected and assembled at our headquarters in Minneapolis, MN USA.
