There are three ways to approach this. The best may be to approach the strata committee with a plan that they can adopt. Provide them with a cost estimate and a compelling argument as to why they should install the racks at Owners Corp expense.
If that doesn’t fly, do the same at your next AGM and get the owners behind the project.
And if they just don’t want to pay, ask if you can do it at your own expense, offering to take responsibility via a by-law. But start with the first idea and gather as much information as you can about how many bikes there are in the building.
The arguments against are likely to include that the OC doesn’t want to be liable for stolen bikes. The response is that they put up a sign or pass a by-law saying bikes are left at the owners’ responsibility and should be insured against theft or damage.
The other one will come from fearmongering about electric battery fires. Again, just have a notice saying eBikes must not be charged on common property.
