Newbie looking for your help/advice

Good day electronic pro’s, I am very new to the scene of electric bicycles and have been very impressed with your website and your ability to help each other and share knowledge. So much so that I am now interested in building one for myself. But being new also comes with admitting that I know very little about this field regarding how to set up and configure the parts and pieces I will be needing, so with that I am looking to you for your advice/help.

450 watt front motor from wilderness energy problem

:?
A member asked m:

I have a 450 wat front motor from wilderness energy. I has about 20 hours on it. It has started this new and scary thing. It will suddenly vibrate like the motor is going into reverse and forward twenty times a second. What is it?

how to test the motor?

Hello,
i have a pedelec and have problems with it. now the motor is not functionning. of course there may be many reasons. but now i would like to test the motor directly, without controller and throttle and sensor to initiate it. how can i do this?
my idea: take my battery (36V = 3x 12V led battery) and apply the voltage to the motor and see if it works.

Charging 2 Dewalt batteries in Series..

This doesn't seem like it would work, but I've been surprised enough times by these batteries to pose the question anyway:
Can I wire 2 36v Dewalts in series for 72V and still charge both of them with 1 stock charger while they're wired like that? In other words, will the stock Dewalt charger handle a big 72V battery when it's used to 1 36v battery?
