An aquabike fleet is one of the few pieces of equipment in a leisure or aquatic centre whose payback can be modelled from four inputs, and on realistic assumptions a 25 bike installation recovers its cost in well under a year. The reason is structural: revenue is earned per class place, not per bike, so the same asset is resold ten to fifteen times a week. This article sets out the four step model we use with centre directors and finance officers, with catalogue prices, a corrected revenue calculation and the sensitivities that decide whether the business case survives contact with reality.
Step one: the full initial investment
Most failed business cases fail here, by counting only the bikes. A working aquabike programme needs sound, lighting, signage, coach training and a launch campaign, and every one of those is a condition of the revenue assumption rather than an optional extra.
| Item | Basis | Cost for a 25 bike fleet, excluding VAT |
|---|---|---|
| Aquabikes | Inobike 6 Air aluminium at 1,080 EUR each | 27,000 EUR |
| Humidity resistant sound and amplification | Essential for group classes | 2,000 to 4,000 EUR |
| IP65 LED ambient lighting | Strong perceived differentiation | 1,500 to 3,000 EUR |
| Zone marking and signage | Safety and user orientation | 500 to 1,500 EUR |
| Coach training, 2 to 4 days | Key driver of long term retention | 800 to 2,000 EUR |
| Launch communication, 3 months | Varies by catchment | 1,500 to 3,000 EUR |
| Total | 33,300 to 40,500 EUR |
Bike choice moves this figure substantially. The WR Max aqua bike is 745 EUR excluding VAT, which brings a 25 bike fleet to 18,625 EUR, while the Waterflex Fit’s Pool at 5,990 EUR excluding VAT is a different class of product intended for a different specification. Published figures of 1,400 to 2,000 EUR per unit for this category do not match our catalogue, and any quotation we issue uses the catalogue price.
Step two: model the revenue per class, not per bike
The formula is straightforward. Annual revenue equals classes per week, multiplied by places sold per class, multiplied by unit price, multiplied by 46 weeks. The 46 weeks reflect 52 less six weeks of cumulative closure for summer, holidays and public holidays. Prices below are shown including VAT at the French standard rate of 20 per cent, with the net figure calculated from it; substitute your own rate if you operate elsewhere.
| Assumption | Low | Medium | High |
|---|---|---|---|
| Classes per week | 8 | 12 | 18 |
| Average fill rate | 60 per cent | 75 per cent | 90 per cent |
| Places sold per class, out of 25 | 15 | 19 | 22 |
| Average price per class, including VAT | 12 EUR | 15 EUR | 18 EUR |
| Annual revenue including VAT | 66,240 EUR | 157,320 EUR | 327,888 EUR |
| Annual revenue excluding VAT | 55,200 EUR | 131,100 EUR | 273,240 EUR |
A correction is needed here, because the figures that circulate for this model are internally inconsistent. Applying the stated formula to the medium assumption gives 131,100 EUR excluding VAT, not the 118,750 EUR often published, and the high assumption gives 273,240 EUR rather than 207,900 EUR. The low case is the only one that reconciles exactly. Use the recalculated column, and treat the high case as an upper bound that requires 18 classes a week at 90 per cent occupancy, which very few centres sustain outside a launch period.
Step three: the annual operating costs
| Cost line | Basis | Annual cost for 25 bikes |
|---|---|---|
| Instructors | 12 classes per week, 46 weeks, at 30 to 40 EUR per class | 17,000 to 22,000 EUR |
| Preventive maintenance | 2 per cent of fleet value per year | 800 to 1,200 EUR |
| Spare parts and corrective service | Depends on original build quality | 1,500 to 3,000 EUR |
| Ongoing communication | Social media, print, newsletter | 1,000 to 2,000 EUR |
| Energy for lighting and sound | Marginal against the rest of the centre | 300 to 600 EUR |
| Consumables | Matting, hygiene products | 200 to 500 EUR |
| Total | 20,800 to 29,300 EUR |
Step four: payback and three year return
Take the medium case: 131,100 EUR of net revenue against 25,000 EUR of operating costs gives about 106,000 EUR of annual contribution on an investment of roughly 37,000 EUR. That is a payback of four to five months and a cumulative three year return of several hundred per cent. Even at the low case, 55,200 EUR of revenue less about 21,000 EUR of costs leaves 34,000 EUR a year, which still clears the investment inside 13 months.
The honest caveat is that this arithmetic is driven almost entirely by the fill rate and the class frequency, not by the equipment price. Halve the fill rate and the payback triples. The break even point sits at roughly three to five classes a week at 70 per cent occupancy, which is the number to defend in front of a finance committee, rather than the headline return.
What determines whether the fill rate holds
Three operational factors decide it. Timetable placement comes first: aquabike competes with lane swimming for water, and a programme squeezed into unattractive slots will never reach 75 per cent. Instructor quality comes second, which is why the training line in the investment table is not optional. Equipment condition comes third: corroded frames, seized adjusters and worn pedals are visible to every participant and they end retention. Specify bikes designed for permanent immersion with corrosion resistant construction and drained components, and confirm the warranty explicitly covers partial immersion.
Frequently asked questions
How many bikes should a first installation have?
Between 12 and 25, sized to the pool area you can dedicate without disrupting other programming. A fleet of 12 lowers the entry cost and proves demand; going to 25 later is straightforward if you have specified storage and handling from the start.
Where do the bikes go between classes?
Out of the water or to the pool edge, which means handling and storage have to be designed in. Aluminium frames are chosen partly for this reason. Plan the storage footprint and the route from pool to store before ordering, because a fleet that is awkward to move gets left in the water and ages faster.
Can the same model be applied to indoor cycling on dry land?
The structure transfers, but the numbers do not. Studio bikes cost more per unit, classes are usually larger and the competitive environment is denser. Rebuild the revenue table with your own class capacity and pricing rather than reusing these figures.
What maintenance does an aquabike fleet need?
Rinsing after each session, weekly inspection of adjusters and fixings, and a documented quarterly service. Budget roughly 2 per cent of fleet value per year for preventive maintenance and keep pedals, adjustment knobs and saddles as stocked spares.
Is the investment eligible for public funding?
Public aquatic centres frequently fund equipment through capital programmes rather than operating budgets, and the payback figures above are usually strong enough to support an internal business case on their own. Documentation requirements differ by country and by funding stream, so confirm the evidence needed before the specification is written.
