That's what you want. Sounds like a fine piece of kit, especially the Bosch motor, though really it's up to you if you want to spend that much on it. If it's to help you ride and get fit then it'll be perfectly suited for your needs.
One word of advice I can give is, the boost you get from pedalling, even in it's eco mode, can be quite startling the first time you use it, at least that's been the case from the ones i've tested! It's immediate and chances are it might only ever be the only mode you need to use. You'll still get exercise regardless of the boost, it's mostly there just to take the strain off your legs and tendons when setting off. Once you're moving you'll still get the cardio training you're seeking, there's no worries there, just without the strain and wear and tear on your legs.
