To get a 150 mile electric only range you are going to need $6,000 or more in lead acid batteries and that is if you can keep the watt hours per mile down to 200 watt hours per mile, for that you will need a very light, sleek, small vehicle, but for that kind of range you will be pulling around 3,300 or more in lead acid batteries.
I think that when you get in your hybrid vehicle being able to tell the vehicle how long your trip is going to be is important, if it's a short trip it runs on 100% longer trip and the engine kicks in once you are over a set speed or after the battery pack is depleted a set amount, really long trip and the battery pack is only used for low speed driving and giving the gasoline engine a boost for hills and passing.
I don't like the idea of building a car from scratch, I've built vehicles for the super mileage competitions when I was younger and stuff like steering and suspension is hard to get right and make it last, doors are also really hard to build and have work right.
I'd also skip the motorcycle engine, because they are tuned for high RPMs and high power output without much thought to gas mileage, if there is room I'd opt for a Geo Metro XFI engine or a small diesel engine.
