I'm looking to move from a hybrid driving/riding commute to riding the whole way.

Unfortunately, I am not in good enough shape to ride 60 miles a day. In fact, as a heavy guy at 40, I'm not sure I'll ever again want to ride 60 miles a day purely on my own power when I have a time deadline.

I'm hoping to find the ebike setup that can get me to and from work, travelling at least 20 mph, and either have reasonably priced batteries so I can buy tow of them, and charge one at work while using the fully charged unit to get home at night.

A little about the commute.

31 miles each way, most of it interstate or highways.
mostly flat, with some long very gentle hills.
When I've ridden the commute, it takes 2.5 hours, and I just cant put 5 hours a day into commuting.
The daily wind conditions mean that I have a headwind both ways, another reason I'm seeking some assistance on the ride.

A little about me.

I'm an uber clyde. 300lbs, I ride a lot, but cant do a 30 mile ride in a reasonable time frame.
I can ride 30 miles, but not at 20 mph, that and I'd be pretty wiped at the end.
I'm fairly technically inclined and good with tools, and ok with welding, so a reputable kit is not out of the question at all.


a little about the bike I'd like.
If possible, I'd love it to be a tadpole style trike. In a perfect world, it would be a tadpole that I could put a frontal fairing on to reduce how hard (for a given speed) the motor and I have to work.
I'd need enough range to at least make the trip 1 way, preferably both.
It doesn't HAVE to be an ebike, I'll consider gas powered, but battery is my preference if it can do the job.
it needs to not be so heavy that I cannot ride it home if the power assist fails.
obviously it needs to be built well enough to handle a heavy rider, riding it 15000 miles a year.
Oh, and of course, I'd prefer it be within the cost of a few years of commuting via my fairly efficient diesel bug. That said, I'm not out to buy or build cheap if there are options that will be good quality for the money, I'd love to look back in ten years and still be using the same bike (although of course the battery will have been changed several times by then).

Thanks, all constructive input is welcome.
