Say Hello to Storm

That is most impressive. I have to... wait. Projects for are on hold till the snow melts, and then I can sell my old bike to fund my new one and make money in other ways. After my predator 79cc bike is done, I'll move on. I'll probably sell it for an electric. Do you feel that 36V is better than 48 for hills and commuting?

48v is better. Generally speaking higher voltage is always better, with consideration to how big a space you have for the physical size of the battery. 48 volts seems like a good compromise between power output, and the battery's physical size.

I'll show you what some of us have done with our bikes. Storm's come stock with a little 36v 8.8 amp hour bottle battery. That's a common size, and type of battery for a low end eBike. One of the biggest problems with a home built eBike is where to put the battery without ruining the bikes looks.



This is my 48v 30 ah battery, and my bike still looks stock.

Power=Voltage*Current.
The more Voltage you have, the less Current (Amp Hours) you need to draw.

For guys like me and Tim the Tool Man Taylor however, it's always about More Power (grunt, grunt) ;-}

Are you just using the stock motor hub with the 48v battery? I guess that would hold up fine. I can see there's a lot of extra space in the compartment.

Yes at first all I did was up the voltage on the stock motor. That worked fine with the only complication being my controller had to also be upgraded to handle higher current. I ran that setup for over a year with no problems.

Recently though, in the pursuit of mo powa, I swapped out the guts of the 350w motor with a 750w motor. A very easy change that takes about 2 minutes.

Nice. I'll be doing 1000watt because I like the "motorcycle" appeal vs the "Boost your bicycle" trend.

Ya, I think that way too...

That recumbent trike was an electric shifting rocket sled worthy of Buck Rogers ;-}
 
I dare say you've posted a picture of that bike 20 times in the past few months. Lol!
How about a ride video?

And that trike looks awesome. However I've never ridden one.
 
YA MAN! WE WANNA RIDE VIDEO! Love love love your Storm. Plotting and scheming a fatty electric build once I've finished Reverend Iggy.

I've never really gone to any effort but here's what I've got. These are pretty short.

You know one thing I like about electric fat tire bikes? They can go on snow. And there's a lot of snow in Hood River and two mountains within 1-2 hours of driving.

A Sondors at 350 watts, single speed, 36 volts, 8 Ah battery and heavy is no snow bike or sand bike.

You need much more for snow and sand.
