The Kit

Our kit is the missing link DYI electric motorcycle builder wishes they had, it’s not only the brackets that hold the motor to the frame, but it also connects the motor to the rear drive wheel and it does it without wasting any space.

Our bracket kit bolts on to the frame using the same 3 bolts as the lower half of the engine, while the adapter shaft lines up perfectly with the swing arm’s drive shaft, 4 more bolts hold the motor securely in place.

It’s the best way to quickly start your project, and save money by eliminating the need to buy custom made sprockets or hiring a machine shop to make costly one off parts for you.



Our goal is simple, to  help you build an awesome electric motorcycle, we don’t want to convince you that you need to buy batteries from us just so we can be a middle man.
As the electric car market grows the options of quality used EV batteries grows too, so Nissan Leaf, Chevy Volt and even a few Tesla S batteries are becoming more common on the used market, so if you are up for a good scavenger hunt you might luck out and find some used EV batteries that would work great on your motorcycle, if not then what we recommend is to seek out large format lithium batteries, such as those sold in the hobbyist market by GBS, Calb, or Winston Thunder Sky.

How many batteries can you pack on your bike? with most builds the CX500 frame can  handle about 150 pounds of battery weight on top of the weight of the motor, speed controller, battery box and peripherals while still being near the stock wet curb weight of the gasoline motorcycle.
Going above the stock curb weight is not advised, as the brakes and suspension would be pushed to their limits.

Options for batteries could even include spill proof sealed lead acid batteries, if you are simply looking for a low up front cost and can live with a range of 10 to 15 miles that lead acid might give, then lead acid batteries might be a worth while consideration.

Safety first! be sure you have a good understanding of the safety required before working with any battery pack of any voltage, batteries store a lot of energy and has the potential to do a great deal of damage or even kill if not handled carefully.


Our kit is designed to work with 19 spline golf cart and NEV (Neighborhood Electric Vehicle) Motors, so you have a wide range of used stock motors to choose from if you are on a budget, as well as a large selection of high performance motors that are available.
All of these motors are designed to be as compact as possible, freeing up valuable space on your motorcycle, while also bolting on with a common bolt pattern so you have used options from your local golf cart shop or NEV dealer, or dozens to choose from if you choose to shop around for something with even more power!

The two most common types of golf cart motor out there are Series Wound motors and SepEx motors.
With 3 Phase Brushless AC motors slowly gaining popularity, but are still somewhat rare.

Series Wound motors are one of the most powerful motors for their size and weight, they also tend to be low cost because they don’t use any rare earth magnets, the draw back is they do not support easy, cost effective regenerative braking.

SepEx or Shunt Wound motors are slightly less powerful then series wound motors, they tend to be low cost as well, their advantages include easy regenerative braking, simplified reversing by sending a signal to the speed controller and under light loads SepEx motors can be more efficient, leading to all around greater range with the same size battery pack.
The main draw back is that they are slightly less powerful with less peek torque from a dead stop.

AC 3 Phase motors are pretty new on vehicles even tho the motors have been around in factories for decades, the main reason is that AC motors that you want to vary the speed of require a speed controller that is also an alternating current inverter with a 3 phase output.
3 Phase motors tend to be some of the most efficient, many of the 3 phase speed controllers also offer regenerative braking, so if you want to get the most miles per charge they are a great choice, the biggest disadvantage is the motor and speed controller combination also tend to be the most expensive of any option.
