Pirez electric bikes are one of the biggest importers of E-bike conversion kits and Bafang motors into Australia.

We have been working with Bafang motors for many years. If you are considering installing your motor or electric bike conversion kit yourself please check out our helpful installation guide in the Resources tab.

Covert to electric bike from a traditional bike using our E-bike conversion kit

Benefits of converting your existing bike to an electric bike with our conversion kit include lower carbon footprint, easier parking, savings on fuel, less fatigued compared to a traditional bike, efficiency in climbing hills, affordability, DIY aspect, and more.

What do I need to install an electric bike conversion kit?

The bare minimum would be:

A mid-drive conversion kit (includes most necessary components)
A compatible battery.

To assist with the Ebike conversion kit installation we also offer:

Pirez Installation Tool Kit (Basic or Premium)

This provides most of the tools needed to complete an installation. You may already have some of these tools, but again we suggest as a minimum to buy the mid-drive installation tool, which can be purchased separately.

To ensure that a motor sits perfectly on your bike and correctly aligned with your chain line, we provide a Pirez Fit Kit, which includes washers, spacers, and longer screws that will help position the motor perfectly.

What recommendations do you give for electric bike conversion kit installations?

Recommendations for electric bike conversion kit installers include:
- Installing a gear sensor that cuts off the motor when changing gears.
- Upgrading the chainring to a premium Lekkie Bling Ring. These have a narrow-wide tooth pattern which vastly minimizes chain derailment and has increased durability by thickening the teeth.

How can I know if my bike can be converted to an electric bike using a conversion kit?

There are two (2) main things you need to take into consideration when determining whether your bike can be converted to an electric bike using our E-bike conversion kits.

1. Electric Bike Bottom Bracket Size

The predominant bottom bracket size is 68mm-73mm.
If your bike has a bottom bracket between these sizes then any of our mid-drive motors will fit onto your bike.
If your bottom bracket is larger, our 1000w motors also come in two (2) other sizes to suit 100mm and 120mm.
These are generally suited to dual suspension bikes and Fat bikes.

2. Electric Bike Battery Styles

Your bike will need somewhere to position the battery.
We have a wide variety of compatible batteries suited to the differing bike styles, including:

Measure your Bike to know If it can fit an Ebike Conversion Kit

To determine whether a battery will fit onto your bike, you will need to measure your bike and simply compare it to the measurements provided in the Specifications tab on the product page listing on our website for your preferred battery style.
