What they fail to tell you is how heavy the bike becomes with the lead-acid battery pack and the electric hub motor.

I built something similar for my wife using a kit and a Specialized Hard Rock aluminum MTB bike. Altogether the bike probably weighs about 60lbs. Add the rider and a steep hill and you will find yourself dead in the water less than half way up the climb. It just can't pull that much weight.

I'm guessing the 15 mile range is optimistic.

When the batteries are new and the rider weighs less than 100lbs.

Built by "Lee Liacocca's" company. Got to love it.

I find every bike I own can make it up ANY hill, no matter how steep. Its just the rider that can't make it. So that's where I need the improvement. Apparently, there is nothing wrong with my bike(s). But that old guy mounted on it, he has problems.

Don't scoff. Electric bicycles are becoming seriously useful. They're not for me, and they're not for everyone, but they're catching on, after many false starts.

I can agree to that. I'm sure they will improve in leaps and bounds over the next decade. I have no interest in them now at age 28... but who knows what the future holds.

I opened this thread expecting to see some thoughtful discussion of gearing, bike weight, wheel/tire diameter and maybe even crank length.

That's a 38T and I have a 26T Biopace granny I *could* put on it but that would be ridiculous 26/38? Hahaha!

I know...but actually as it worked out it's 10 very nice, equally spaced ratios in the five 13-28 cogs and 50/45. And 45/28 is a fairly low gear too. Throw in the 28/28 and 28/38, haha. While I did initially do it to prove it, I plan on leaving it, why not? One of these days I'll find a paved 45 degree incline somewhere to try to go up

Incidentally, I can shift the 50/38 too...that was a requirement as I didn't want to have any chance of a bad combo.

Here's the gearing as it sits:



And what the heck, with the 26T granny thrown in and a slight update for tire size:



Hahaha!

18.5"(!) That's like Big Wheel gearing.

Colonel, sorry to disappoint! I have to say, more than anyone else on this forum, sometimes you just crack me up with your humor! Always highly entertaining!

I have no interest in them, either, and I'm 50.

now that I have a 34/32, I don't think there are too many hills I'll be tempted to walk up. The rider of lower quality e-bikes like in the OP may not even be able to push them up some of the hills I can ride up.

My mistake - I fully intended to say 26T.

Maybe you can swap for an MTB crankset and gear it even lower - though you'll probably start stripping cog teeth by then.
