Thanks for the input everyone. Just pulled the trigger on my order. I'll update with the build process and finished product soon!

Bump for Monday crowd.

That motor is rated at 270, which seems a good medium. I'll be riding paved roads with a decent amount of incline. By my calculations that would give me a top speed of 20.9 mph. Seems fast enough for my liking I was planning to get the tools I'll need on amazon, but I'll check out your...

I was around last year briefly with similar plans before an injury derailed my project. I've got a Specialized Hardrock mountain bike to start with. I've got my cart together with BMS battery and would appreciate any feedback. Mainly looking to confirm that I have all the smaller items I’ll...

Slight amendment...I had the wrong idea of % slope. My neighborhood hills are ~10 degrees, so ~17% slope

I'd trust your experience over my thoughts, thats what I'm here for. I guess I'll go for 270. What material battery would you recommend?

My main design requirement is climbing a couple steep hills in my neighborhood. I'd guess the biggest one is about 200m at 8-10% grade. That is why I was thinking the lower rpm for higher torque. I can live with lower speeds

Ok, I'm getting close. Bafang CST motor - seems to be out of stock at bmsbattery. http://www.elifebike.com/peng/iview.asp?KeyID=dtpic-2013-9T-F37E.74VMQ Options: 36V 500W, with controller, PAS, throttle, brake lever I think its 205 RPM. I'm getting a 26" wheel. Should I scrap the extras and...

saving for later. I think I will be using the same setup

So I like the suggestions of the smaller motors. Let me make sure I am applying these concepts correctly. Comparing a 36V 500W motor to a 48V 500W motor - the 48V will translate to a higher top speed. But since they have the same wattage, the trade-off is less Amps - which translates to...

Thanks for the input guys. I will keep doing some research and hope to get started in the coming weeks!

I am researching my way towards becoming an ebiker. I have a very basic understanding of ebikes after doing some reading this weekend. I wanted to discuss my ideas here - I'm sure this type of topic comes up all the time, so if mine is not unique, just point me where I can read up. Background...
