## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=POLOLU-601:1` (comma-separated SKU:qty pairs) and share the link. Opening it shows a confirmation page with live pricing and stock before anything is added to the cart.
- **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/POLOLU-601:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.)
- **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there.
- **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works)

## Description

This hard plastic wheel is specially designed for the Solarbotics [GM2](https://core-electronics.com.au/solarbotics-gm2-224-1-gear-motor-offset-output.html), [GM3](https://core-electronics.com.au/solarbotics-gm3-224-1-gear-motor-90-deg-output.html), [GM8](https://core-electronics.com.au/solarbotics-gm8-143-1-gear-motor-offset-output.html), and [GM9](https://core-electronics.com.au/solarbotics-gm9-143-1-gear-motor-90-deg-output.html) gear motor output shafts. It also fits on the largest [Pololu plastic gearmotors](https://core-electronics.com.au/category/56/pololu-plastic-gearmotors) (although the included screw might be too short for these motors). While the GMW wheel can function as a wheel all by itself, the four convenient mounting holes also let you use this as a wheel adapter to attach a larger wheel, or to attach legs and other mechanisms to your gearmotor.

This plastic robot wheel is 1-3/16" (30 mm) in diameter, 0.28" (7 mm) wide, and the double-flat slot fits snuggly onto the shafts of the [Solarbotics gearmotors](https://core-electronics.com.au/category/40/solarbotics-gearboxes) and [Pololu plastic gearmotors](https://core-electronics.com.au/category/56/pololu-plastic-gearmotors) listed under the related products on this web page.

#### Included Parts

- One gear motor mount
- One screw (might be too short to work with the [Pololu plastic gearmotors](https://core-electronics.com.au/category/56/pololu-plastic-gearmotors))
- One washer
