@ReadyShreddy Forget what you have already paid, that option is common to all three options and in any case, you are not getting that money back. It's gone, forget it!
Option 1: Even if you really like the bike, I agree that you are unlikely to still want it after another 4 years (assuming it still works).

Option 2: If you buy it now, you are getting a good bike for £1000, that is if you like the bike. Even if you don't like it, you could pay the £1000 and sell it for more! And if you can't expect to get at least £1000 for it, then why are you paying £1000 for it now?

Option 3: If you return the bike, I assume that you will have nothing to show for it,
except that you are free to buy anything you like.
The choice will depend upon your financial circumstances (see the thread on how you pay for your bike), and how much you like your current bike.
On balance, I favour option 3. Walk away with what you have learned about e-bike ownership and invest in a new bike of your choice. Put your £1000 into that new bike, unrestricted by the terms of your current cycle to work scheme.
