Getting a Kit - Resources

Start Here

This is a landing page for people who are relatively fresh to DIY ebikes and are thinking about doing a conversion. It outlines what the conversion process entails, and provides multiple links to different parts of our website that you really should read and understand before contacting Grin with further questions.

Kit Types

We have a few different types of conversion kit available for any given hub motor. Barebones systems for a basic throttle-only setup, Superharness systems for the addition of pedal sensors and modern ebike displays, and Cycle Analyst systems for the most customizable feature set.

Hub Motor Options

Compare ebike hub motors, geared versus direct drive: the light Bafang and Shengyi kits, the powerful eZee and GMAC, and the Grin All-Axle. Front versus rear, power, weight, and regen braking, plus the Max45 fatbike and FH212/RH212, with where each fits best.

Battery Options

Similarly, there are quite a few battery choices available, in different voltages, form factors, and capacities. This page goes over the process of selecting the right battery model in our catalog for the needs of your particular project.

PAS Options

Ebike pedal-assist (PAS) and torque sensor options for Grin kits: cadence magnet rings, chainring sensors, and bottom-bracket torque sensors, for CA3 and Main9 systems. How each works and which to choose.

Kit Installation

Grin primarily focuses on supplying parts to DIY builders and ebike enthusiasts who will install the parts themselves, and we have extensive documentation and videos showing that process. But for local customers in Vancouver we also offer retrofit services where you can drop off your bike and have our staff do a professional retrofit with Grin hardware.
