I've read this thread from start to finish, lots of good points raised on both sides. A couple of things though that I'm surprised no-one has mentioned, first of all, if you want to save some money, like the car scrappage scheme, you can encourage your employer to start a Cycle To Work scheme. That's how I'm buying the Fast4ward Peak I've just got, and with the tax benefit saving it works out at about £670, and you get to pay weekly for it.
People mentioned the health benefits, reduction in pollution etc, and benefits to the Gov't (healthier people, lower NHS costs etc), however no-one has mentioned that using your bike means using your car less - loss if tax from the fuel you are no longer buying.
I'm a classic example, liked bikes all my life, but couldn't face the ride to work, boring, repetitive route, especially the return trip after a hard days work. Our company started a Cycle to Work Scheme, and I considered whether or not to get a bike for work. I'd often looked at eBikes over the years, but never took the plunge due to the price, but they fulfil my love of gadgets, and bikes.
The scheme offered a big saving, the more you spend, the more you save, so ideal chance to get one. The electric assistance would be a great boon for the return trip home too. So I ordered one.
In the three weeks I've had it I've only used my car twice, once the first week when I got up to go to work to see I had a puncture, and once because it was raining. I reckoned if I could save £10 a week on fuel it more than covers the cost of the bike, up to now it has.
So I'm getting some exercise I wouldn't have been getting, enjoying the ride now, and saving money on fuel. The exchequer however has lost money in the lost fuel duty and vat I would have paid on the fuel I haven't bought.
There are savings for the company too, as they claim back 13% on the national insurance they've have paid on your behalf, and can also claim back the vat on the bike if they're vat registered. So there are other ways of getting a cheaper bike than just the vat reduction.
PS: Just got soaked coming home from work tonight. ;(
