The cheapest way to do this would be a mass produced and therefore low cost standard bike, but with instant plug in controllers available.
Then the customer could buy a controller for economy, or one for performance, or a middle of the road compromise. They could have two, one for workaday use and one for weekend use for either long runs or performance enjoyment
Since controllers are small and could be miniaturised much further, they would also make handy immobilisers for use in addition to a lock.
