So I have been planning to build an ebike and using it as a commuter for a couple of years now. It seems that everytime I get ready to do it, something happens to prevent it.
Anyway, I am ready now and planning to start as soon as this weekend or next weekend.
What I am trying to do is put something together that meets the following:
1: Will reliably carry me (and I weigh around 245 pounds).
2: Will hit 20 MPH with no pedaling (or faster).
3: Will make it up a decent hill with no pedaling.
4: Will be as light as possible.
5: Will easily fit on a folding bike with 20" wheels.
6: Will not have any drag if I pedal without motor power.
7: Will be as quiet as possible.
8: Will have a range of at least 10-15 miles with no pedaling (the more the better but I need at least 10-15 miles).
9: Can be kind of hidden so it looks like a normal bike.
10: Can withstand a ride in the rain.
Basically, the idea is to have a small folding bike I can ride to the train station, fold it up and carry it on the train, and after getting off the train riding the bike the rest of the way to work. I would then fold the bike up and keep it in the office. And of course, do it all again to get home.
Now I am pretty sure I will have to compromise on some of those. But I'm hoping you guys can help me find the best combination that meets the most of those requirements. It looks like there are new technologies/vendors/etc than there was when I researched this a couple years ago, so I am somewhat out of the loop.
Any ideas or suggestions would be very much appreciated.
