Connectors

Connectors are everywhere on an e-bike and are super important to being able to maintain and expand your e-bike.

A brief list of common recommended connectors is as follows:

• XT90-S: 2 pin, 90A rated. Soldered. Very good connector with anti-spark functionality that reduces/eliminates sparking and erosion of the contacts upon repeated connections.

• XT60: 2 pin, 60A rated, Soldered. Very good connector but no anti-spark functionality and hence best only for occasional disconnections.

• MT60: 3 pin, 60A rated, Soldered. Good connector for phase wires.

• Anderson Powerpole: 40A rated, Crimped. Very good connector that has a sacrificial tip designed to take the wear of sparking without eroding the main contact area.

• JST-SM: Low current rated, Crimped. Good for signal lines like throttle and very low power like LED turn signals and such. Good connector for hall sensor wires.

• Higo: An over-molded type of connector that can't be easily used in DIY as you have to splice to a pigtail to use one. Water proof and very good, comes in many formats and current ratings including combined hall/phase wires for motors. Highly recommended to get if you can find a controller and accessories already using them.

Connectors we don't recommend:

• Bullet connectors: These are generally only good for around 15A, often have poor tolerances and can come loose with vibration and melt even when used at rated current levels.

• Spade connectors and terminal blocks: Often found on the phase wires of cheaper motor kits, these connectors often are of poor quality and melt under the currents.
