Risks And Constraints

Route safety — the biggest constraint

The route survey reversed the launch region. The
Riesling Trail, Clare Valley is #1: car-free
rail corridor, flat, 12–15 cellar doors within 1 km. The Barossa Trail is #2
and not what it looks like — best short-let supply, but only ~3 cellar doors on
the path. The Yarra Valley is ruled out — 40 km of traffic-free trail with
zero cellar doors on it, every winery on 80–100 km/h highway. Mornington,
Hunter and Swan Valley likewise. See the Route Survey chapter.

Pick a route built for cycling and the van is optional; pick a road cycling
colonised and the van is compulsory. Clare's trail does for free what a Barossa
van must be paid to do.

Alcohol and liability

Victoria has no specific offence and police cannot breath-test cyclists. South
Australia is different: under Road Traffic Act 1961 (SA) s.47 a rider can be
convicted regardless of BAC, facing a fine up to $500.

CORRECTED 2026-08-13. This section previously reported "up to six demerit
points against a driver's licence with possible suspension", making the van a
licence-protection device. That rested on one commercial law-firm page. The
primary source — the SA Law Handbook —
has now been read: it confirms s.47 applies to cyclists and specifies the $500
fine, and says nothing about demerit points, disqualification or suspension.

Survives: drink-riding in SA is a real offence, unlike Victoria — so modest
pours, purchases collected not carried, frictionless ride-or-van choice at every
stop. Withdrawn: "you could lose your licence." A $500 fine risk is a reason
to design carefully, not a reason a customer buys a van. Keep it out of customer
and investor material. Next source: SAPOL PD320A.

Guided operators sell alcohol-plus-cycling here at $195pp, so it is insurable in
principle. But no Australian broker or underwriter publishes a premium for
self-guided e-bike hire with alcohol en route. Marsh's $505 tour product
excludes both "cycling tours" and "pub crawls"; the guided competitor carries
$20m at Lloyd's. The realistic failure mode is declinature, not price.

Wine de Roads (Oregon) says insurance restrictions stop it offering e-bikes at
all, and two others refuse them on alcohol grounds — against ~20 who do rent
them. A risk flag rather than a kill signal, but it goes at the premise.

Unpriced compliance, ahead of the insurance quote: SA Passenger Transport Act
accreditation (a licence-or-not question, not a price one) and a Riesling Trail
commercial permit (NSW comparator: $3.00/user/day).

Other constraints

• Seasonality — 30–35 weekends was optimistic by up to 20%. There are only
  60.6 weekend days in an Oct–Apr season; BOM rain and ≥35°C data for Clare
  give 52/60/66 operating days across the ramp.
• Bike capex — Takaro Trails benchmarks e-bikes at NZ$4,500, above the
  $3,500 assumption. The model's answer: don't buy bikes in Year 1. Partner
  below $42/bike/day at maturity; saves ~$63k cash.
• Cancellation is constrained by distribution. GetYourGuide delists above a
  1.0% cancellation rate, so "we run if we get six" is incompatible with OTAs.
  Per-vehicle pricing (Buller: "$250 per trip, up to 5 passengers") resolves it.

Kill signals

• No loop with ≥8 cellar doors and acceptable separation from traffic.
• Fewer than 7 riders/day — the model puts break-even at 14.3 riders/day,
  79% of one van's capacity. The original threshold was far too generous.
• Insurance above ~$45k/yr — beyond that the business fails at any price or
  volume one van can serve.
• A 60 km e-bike loop yields ~9 riders/day against 14.3 needed. Range is a
  reason to keep the loop short, not extend it.
