I have a Bafang middirve + 52v battery mountain bike build that I'm enjoying tremendously. Now, for my next project, I want to build a 20"-wheel folding rear-hub-motor e-bike for inner-city commuting. For my base bike I will probably use a Dahon Speed D7.
My question is what kind of hub motor and controller to get. I see there's a popular thread with the most powerful hub motors of 2016. But, I don't want anything too powerful -- this will be for 20~30mph stop-and-go city biking and I want to keep it light. The limitation is I want this to work with the battery I already have (52v) so I can just switch the batteries between the bikes. (I will likely keep the battery in my backpack while riding.) My (limited) understanding is that with higher voltage comes higher power and to keep up with higher power without melting you need a bigger motor (and also an appropriate controller). Hence my hesitation and my seeking help in your greater wisdom.
So what motor and controller combination would you recommend? I would ideally like to get a pre-laced 20" rear wheel kit so I don't have to lace it myself. But I live in NYC so I presume I could find a store that would lace a wheel for me if I have to get a bare motor. I am looking to be economical so Chinese resellers are ok by me.
Thank you.
