Hey, I wanted to inquire as to recommendations for how to go about installing a second motor to my ES2 or ES4 Ninebot. I have a second ES2, so basically double of everything, except another extended battery.

My plan is to put the front wheel of the ES2 on my rear wheel of the ES4. Can I connect a second motor in parallel with the front wheel, or basically wire it in just like the front to both the control board, throttle and battery? Assuming yes, will the control board support the amp draw from 2 motors?

Plan B would be to install a 2nd control board to the ES4 (from the ES2). If this is what I need to do... can I have 2 boards connected to the same power supply on the ES4, and can I use the same throttle? Or will I need to have a throttle for each of them?

I'd like to do this using parts from the ES2, vs ordering additional aftermarket items.

Seems pretty straight forward more or less, but any advice would be greatly appreciated.


Thanks!

Daly

It won’t work with 1 control board, if you connect it like this both motors will have low power and will likely run uneven. You can use single battery, but you will have very short range and battery will loose its capacity pretty fast. So basically the only single thing for both you can have with good results is a throttle. Look for a thread on how to connect it.

So you are saying that even with the ES4's external battery the demands of a second motor would not be mitigated much by the extra watt hours provided by it? Would the range be halved, or are we talking more along the lines of 25% of the estimated range of an Ninebot ES4?

Hey thank you for the link. I was kinda hoping I would be able to keep the look of the ES4 the same. Not sure the dual drive option would be worth all the added bulk, not that it doesn't look fun.
no other way going to work its going add 5-10pounds to the scooter you dont even have to add 2 externals only 1 and charge the second battery reg
