Thanks very much for the info regarding Curry Electro drive.
This build is for some kids I know who will soon be able to ride a bike with 18" wheels.
I am documenting the restoration and hop up as a benefit to others that might encounter
the Mongoose CX24V200.
As you already know, but as a benefit to others, the Mongoose CX24V200
is the baby sister of the Mongoose CX24V450.
Here is a comparison of the CX24V200 and CX24V450
Component CX24V200 CX24V450
--------- -------- --------
Suspension None Front and Rear
Tires 18" Front 20" Front and Rear
Speed 10mph 15mph
Volts 24VDC 24VDC
Watts 200 450
Batteries 7Ah 12Ah
There are a couple of postings about hopping up the CX24V450 on Endless Sphere, e.g.
Mongoose CX 24v450 low speed and high speed options? (your recommendation)

The plan for this bike is to:
- Increase the battery size from 7Ah to 12Ah while using the use the stock battery box (by removing the Styrofoam fillers)
Use LiFePO4 replacement SLA batteriers with built-in BMS, for example

Increase speed to 14-15mph while remaining at 24VDC.
Increasing the speed while remaining at 24VDC is were I will doing more research (thanks again for the info) and probably asking questions from other readers. For example the stock motor is rated at 300 watts but I assume is detuned to 200 watts. It would be nice to run the motor at 300 watts and increase the front (motor) sprocket from 9T to 13T or perhaps 14T. My next posting will cover removing the motor followed by disassembly and cleaning of the rest of the bike. The posting after that will be an analysis of the motor and speed controller and speed hop up options (your 1KW motor included)
Thanks very much again for your reply, help and interest in this project
