OK, since there seemed to be a need for such a thing and there does not appear to be any commercially available units, I designed a throttle interface for RC controllers. This allows you to use a regular bike throttle with a controller made for radio control.
This will work with both a standard hall effect or 5k resistor throttle.
It has an adjustable current limiter based on the Allegro ACS754 bidirectional hall current sensor. The current limit will adjust from near zero to whatever the maximum current of the Allegro sensor is. They have 100 and 150 amp versions in stock at Digikey. If you don't want to use the current limiting feature, it can be left out, but I think it is essential for proper operation on a bike.
There is a tie-in for a battery LVC and brake switches to override the throttle and kill output.
There is a built-in BEC circuit with 100v maximum input voltage.
There is a provision for additional main capacitors to supplement the controller's stock units.
The pulse generator is based on a ICM7556 dual cmos timer that is configured for voltage control. An op amp comparator monitors the current and decreases the throttle when the current limit is reached.
This design has NOT been fully tested yet. Some tweaking of the loop response may be needed depending on the model of controller used with it.

Can you choose either Battery Side limiting or Armature Side limiting?
outstanding work,that makes things so much easier for me, pm me your address and i'll send out a hv110 for testing, try not to pop it now :lol: do we know the rough dimensions of the board?
My latest design uses:
