Salt destroys a brake cable in a season regardless of how far the machine has gone. What that means for a hire fleet.
In most places a hire scooter is serviced every so many kilometres. Here that would be the wrong rule and following it would put somebody in the clinic.
Salt air corrodes a chain, a brake cable and an electrical connector on a timetable of its own. A machine that has sat outside a guesthouse for three weeks doing forty kilometres is in worse condition than one that has done four hundred and been ridden every day and rinsed.
So every machine here goes on the bench every six weeks, whatever the odometer says. Brakes, chain tension and wear, tyres including the inside of the wall where the cracking starts, lights, the fuel line and every earth connection.
The dates are written on a card on the wall beside each machine number and you are welcome to read them before you take one. Nobody ever has, but the cards are there because a shop that is willing to show you them is a shop that keeps them up to date.
Helmets are on the same idea: replaced every two years whether they look worn or not, and any helmet that has been dropped hard goes in the bin rather than back on the shelf. A helmet's shell does its job once.
The practical consequence for you is that we sometimes say no when the shop looks full. A machine that failed its check is off the board until it is fixed, and we would rather lose the hire than argue about a brake later.
