20 inch E-bike ?(pic added..)
 
ok so, I have an old Trek 1.0g collecting dust in our shed.. and I somehow ended up watching too many e-bike movies on noob-tube...

I now have "the itch"...

So,.. my question(s):
would a 20" e-bike be worth-while?
are there any good 20" hub motors?(golden motor?)
would cheap 12v 18ah batteries in series "cut it" for a 36v motor?
how much would I be looking at total for an "el-cheapo" setup?
and.. what kind of top speeds could I expect ?

Ty in advance.

You could always just get a chain drive kit. They mount a small motor on the underside of the frame where the kickstand goes.
I'm still very new to ebikes in general but I did see these when I was doing my research before I bought my bike & they are somewhat less expensive compared to going with a hub motor.

hmm, I'm not even sure a hub motor would fit?..

was also thinking about a 1000w Currie motor mounted inside the frame with a freewheel crank.. not sure that would fit either...

That bike looks like it has a nice solid fork so perhaps a front hub would be your best bet.

I just found this for you

There is a pulldown for wheel size & 20" is listed.

meh, think I'll just say screw it till I get a mountain bike. (though 20"ers do seem rare.. o well)

ebikes.ca have hub motors on 20" wheels.

I'm probably gonna end up trying a gas powered kit actually... wayyy cheaper. (even if they sound like chainsaws...)

thanks though.
