Sourcing Quality Components for the EV Conversion.

A quick search on the internet will bring up a lot of motors, controllers, and battery options, but if you are like me and new to the EV scene, then you may need some guidance.

I searched Motorcycle EV Conversion Kits Australia and at the top of the list was ELMOFO, a company in NSW that goes much further than just selling motors and batteries. They live and breathe EV Conversion and have developed complete kits for Dirt Bikes. After talking to them, I found out they had some other projects of their own on the go.

My first contact was via their website contacts, and Brett, the Managing Director, responded quickly to my questions. I told him what my project was and the expected RPM of the motor that I had calculated from the diameter of the wheel and the sprocket ratios on some dodgy website calculator. At 100 km/h, the motor RPM was calculated to be 469.

Brett thankfully corrected my error, and with the current setup, it would be 3,263 RPM @ 100 km/h. This new information removed the geared motor from the equation as the motor would be at the upper end of its rev range.

The recommendation was to go for the direct drive motor with the 14-tooth 428-pitch sprocket.

I have chosen to purchase the entire kit, as ELMOFO will program the controller to help me get the components to work together correctly. The kit includes:

To power the bike, Brett has recommended a 21S battery pack with a JK BMS, and these are the batteries I have selected.

I have also been talking to Russell, who is involved with the bike conversions and works with the team to put the conversion kits together.

I cannot recommend these guys enough; they have been very helpful and an excellent source of knowledge.

Now that we know what we are putting into the bike, we can design the new structure to fit the motor, batteries, and control systems.
