ELF Parts


Cat got your ELF?

We offer a range of products and services geared towards the Organic Transit ELF, from replacement batteries, to new drive systems, to solar panels, bike components and more. We support the ELF by using an open wiring standard originally developed for e-bikes by Grin Technologies. This ensures that in the future, the things we help you accomplish on your ELF are serviceable and easily understood.

There are several minor upgrades we recommend doing immediately in order to get the most performance and reliability out of your ELF, such as rewiring the key, Cycle Analyst, & solar panel; then there are more involved upgrades available, such as torque sensing pedal assist, regenerative braking, reverse, speed pedelec mode (28mph), cruise control, trailers, USB ports, extra solar, cup holders, and more. Please follow us on instagram for the latest ELF rebuilds, and don't hesitate to drop us a line for more info about all our ELF products and services.


Are you looking to replace the battery in your Organic Transit ELF? Though not the one originally provided, our 48v 16.5ah downtube style battery from Grin Tech. is the ideal replacement. It comes with a 1 year warranty, and is capable of being solar charged while driving (also known as simultaneous charge & discharge) at up to 8 amps. Along with the battery, most ELF owners purchase:

1. Either the SB-50 or SBS-50 power adapter, which allows you to plug this battery right into a standard ELF with no modifications.  

2. 5' battery power extension wire, for mounting the battery farther away from the original connector (such as on the dashboard or around the floor).

3. XLR to Anderson power adapter, which allows for charging the new battery with your standard ELF charger when it's been taken off of the lockable mounting base. This is only necessary if you plan to mount the battery using the included locking mounting plate.
