Mixing hub motors dual control?

[GreenThumb]

I have a rear magic pie 5 and a crystalite hub front motor.

How can I put them on the same bike and controll them?

Any technical help from the experts is most appreciated.

No expert here; but I just finished a dual motor build. What worked good for me was a magic pie on the front (with regen braking enabled) and a geared hub on the rear (Bafang in my case) that can freewheel. The direct-drive in the front offers really good braking without the pads touching the rotors. Rear brakes are rarely used at all.

Each motor has it's own controller and a cycle analyst is used for each one for their throttle output functions. Once you have control over each motors throttle, you are in control of an AWD bike.

Thinking about something like this for brompton although I hear you need a custom back even for the crystallite saw20 etc

What is a "custom back"?

Here's an expensive one with crappy ZEHUS 250w internal battery hub motor https://www.humancycle.cc/product/get-your-wireless-brompton-electric-kit/

Or stuff like this

Fat Rohloff Brompton

This Brompton has 16 x 3.0″ fat tyres, Rohloff gearing and Magura disc brakes, with SON dynamo lighting and custom mudguards.

Probably able to get something similar made in China for less than would accommodate something better,the former offers Ti rear too
