Bikepacking autonomy score: the pre-departure diagnostic

On a bike, every autonomy solution is paid for in weight, and every kilo is paid for again on every climb. That is what makes the bikepacking diagnostic different: it is not about carrying enough, but about carrying the minimum that holds. A 4-axis framework to decide before departure, not on the pass.

Why the bike score is not a lightened trek score

Both practices share the carrying constraint, but not the trade-off. On a trek, weight limits the quantity carried. On a bike, it first limits daily distance: one bag too many is imperceptible at a standstill, and unmistakable after 1,200 metres of climbing.

Second difference, this one in your favour: a bike produces energy while rolling. A hub dynamo turns the route itself into a charging source — something no hiker can do. So the bike score has to arbitrate a pairing the trek ignores: mass carried against production underway.

The 4 axes of the Nomad bikepacking score

• Onboard energy — powerbank and hub dynamo vs real draw (GPS, lighting, phone, communicator). The dynamo only pays off, in weight as in price, beyond a certain trip length: that is exactly what this axis quantifies.
• Water — carried capacity vs the real spacing of water points along the track, personal filtration, and a fallback if a source has dried up.
• Safety & communication — network coverage along the track, satellite SOS in dead zones, a repair kit consistent with the parts actually serviceable on this bike, night visibility.
• Load-route fit — total mass (bike + bags + water + food) set against the intended daily elevation gain, the surface, and the number of days between resupplies.

Reading the score: 3 decision bands

0–40 — Lighten or shorten

The load or the daily distance exceeds what the real autonomy can sustain. Revise the route or the packing list before leaving.

40–70 — Targeted adjustments

Departure feasible with an action list: filtration, an extra powerbank or a dynamo, stages recut around water points.

70–95 — Ready to ride

Autonomy consistent with the track. Re-score if the route stretches or the season changes.

Key takeaways

On a bike, weight limits daily distance first — not just the quantity carried, as on a trek.
Four axes: onboard energy, water, safety & communication, load-route fit.
A hub dynamo turns the route into a charging source: it produces as long as the wheel turns, including in rain.
Three decision bands: 0–40 lighten or shorten, 40–70 targeted adjustments, 70–95 ready to ride.
A formal score is warranted from two days of full autonomy onwards.

FAQ

Hub dynamo or powerbank?

The powerbank wins on short trips: nothing to install, and the weight stays low as long as the number of recharges stays limited. The dynamo wins as soon as the trip runs into weeks or crosses areas without reliable sockets — it produces as long as the wheel turns, including in rain, where solar collapses. The tipping point depends on real consumption, not on a general rule.

Does this score apply to an e-bike?

The 4 axes still hold, but the energy axis changes nature: the propulsion battery becomes the dominant item and makes the route dependent on charging points. Socket availability then structures the track, not water or food.

When is a formal score warranted?

As soon as the route goes beyond a there-and-back day: two days of full autonomy are enough for the gaps to show. Below that, a classic checklist stays proportionate.
