I'm no expert, but I'd go for the first one with a Bosch motor/battery combo. . The range (reichweite) on that one is 110km, supposedly. The range on the 2nd is only 60-80km, supposedly - and there is no mention of the brand of motor. Keep in mind that they overestimate the specs and that there will really be less range - i.e. they base the specs on a very light weight guy riding downhill with a tailwind and minimal electro-assist...
Also, the battery charge is weakened over time and may only achieve an 80% charge after a few years, or less. And cold weather also adversely affects the charge.
When the battery goes dead and there is no electric support, you're left with a very heavy bike to pedal, with a lot of internal friction and drag.
My wife has this bike in last year's model, with the 45km/hr motor and 500w battery. I think it's about as powerful as ebikes come these days.: http://cresta-swiss-bike.ch/portfolio/egiro-plus/
She rides 32 km each way to work and back daily, and it has just enough charge to get her there using full electro-assist. She needs to charge it during the day and again at night.
You also may want to look into a 45 km/hr model - i'm not sure if the 25km/hr models have a governor that limits top speed, but 25 km/hr seems like a joke. However the 45km/hr ones require a little license plate and maybe other red tape...
If you want to go on longer rides than 30 km (approx 1 hr rides), you may just want to get a normal non-electric bike, or I guess you could carry along an extra battery pack. But a 5 hour ride in the country - forget it, unless you only use the electric assist very sparingly. But then you're pedaling a super heavy bike, and you'd be better off with a normal bike and would save a load of cash.
just my opinion and 2 cents..
