Never ever going to happen for a few business model/financial reasons
First, you need a bank to finance the capex. Bike shops run at something like a 5% cash flow margin, so even a small shift in purchase to lease would be impossible for them to bear. I doubt manufacturers would shoulder the working capital deficit either.
Second, you need either a bank or an administrator (usually both) to manage the lease terms wrt floating variables like cash up front, depreciation/residual rate, lease term, etc. managing this kind of thing is a nightmare and its impacted by macroeconomic factors too.
Third, insurance…you will either want or likely be required to insure a high priced leased asset. When you taco your 808 NSWs or crack your leased p6, you’ll probably want to manage the massive spread between the liability and the appraised value of the used asset (‘gap’ insurance) To date, the best option for consumers to insure bikes is veloinsurance, which is offensively priced. Why? No bank capital, byzantine business model of the bike space, no reinsurance, no retail distribution network, other reasons I’m sure.
Few things are more pro than leasing items you can’t afford outright, insuring them, and wrecking them at high speeds, but unfortunately it’s going to be hard to find a backer in the bike space for such moral hazards
