Puerto de la Bahía de Bayur cycling climb profile

Puerto de la Bahía de Bayur is a short, controlled category 4 climb in Indonesia: 3.4 km at an average gradient of 4.48%, starting at 7 m and topping out at 158 m. The headline is not the steepness. It is the consistency.

With a maximum gradient of 4.98%, the climb gives very little evidence of a major sting in the tail or a sharply selective ramp. The average and maximum sit close together, which points to a climb that rewards rhythm more than repeated accelerations. This is the type of ascent where riders lose time less through one bad section and more through riding the whole climb slightly above what they can sustain.

How the gradient unfolds

From bottom to summit, the profile is best read as a steady drag rather than a stepped climb. The route gains 151 m from its 7 m start to its 158 m summit, while the listed total ascent is 131 m, so the practical takeaway is simple: the climb trends upward almost the entire way without needing to be treated like a mountain pass.

At 4.48%, it sits in that awkward range where it can feel easy if ridden patiently, but costly if approached like a sprint leadout. Because the maximum is only 4.98%, there is no obvious reason to save everything for a brutal final wall. The more logical approach is to settle early, keep pressure on the pedals, and avoid surges that create unnecessary lactate for very little speed gain.

Pacing and gearing notes

For pacing, think smooth and progressive. If riding by power, this is a climb to anchor around a sustainable effort rather than repeatedly punching over target. Use your /glossary/ftp as the ceiling, not the starting point, unless the climb is being used as a hard test.

Gearing should be chosen for cadence control rather than survival. The gradient never gets far beyond the average, so you do not need to plan around extreme ramps. The mistake is riding too large a gear early because the slope feels manageable, then finding that the constant resistance has slowly drained your legs by the upper section.

A compact or mid-range climbing gear is enough for most riders, but the priority is staying seated and fluid. If cadence starts to fall, shift before the effort spikes. On a climb this steady, the fastest ride is usually the least dramatic one: hold position, keep torque under control, and let the gradient do less damage than it can to riders who overreact to the opening slopes.
