    WAHOO! ... ER, WAHEELA!

    PUTTING THE GRR! IN GRAVEL

    Waheela was designed from the ground up to be the most versatile gravel bike available. The first suspension-corrected gravel bike on the market, Waheela takes its name from a wolf-like creature similar to the Warakin but more specialized for its environment.

    RIDEFORWARD™ GEOMETRY

    Our RideForward™ geometry is the future of gravel. It redefines the shape of a gravel bike by giving it a longer reach, which increases the wheelbase and provides more stable handling.

    SUSPENSION CORRECT

    Waheela has a suspension corrected 420mm axle-to-crown fork and handles optimally with both rigid and gravel suspension forks.

    "Wow! Is this a mountain bike with drop bars, a gravel rig, an adventure bike, a versatile touring rig, or all of the above? It seems almost overwhelming when you think about all the possibilities this platform presents."

    Riding Gravel

    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.

    "Otso Cycles has really made the bike versatile and has sent the first shot over the bow of other gravel bike makers out there. Expect many bikes to follow in its wake similar to this Waheela S. In that sense, the Waheela S is a pioneering effort and a good one at that."

    Riding Gravel

    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.
