Sure! However, the process is a bit tricky, so it is important to understand each step and find a qualified technician to perform the labor.
Because installing push rims requires specialized tools (like a drill press), extreme precision, and parts that aren't always easy to find, GRIT recommends you coordinate with a professional bicycle technician on every step of the process. It is imperative that you use the correct parts and that a trained professional handles all assembly.
An overview of the process: Acquire the appropriate wheels from one supplier, acquire the appropriate push rims from another supplier, acquire the torque couplings from GRIT, and then find a bike shop with the necessary tools and knowhow to drill into the wheels and install the push rims. Here's a detailed explanation of how to start from scratch and attach wheels with push rims to your Freedom Chair:
Step 1: Acquire the appropriate wheels. You will need 36-spoke, 15mm thru axle rims with an ISO 6-bolt disc brake pattern (i.e., mount for the couplings). Because most push rims have 6 tabs, it is far easier to install push rims on 36-spoke wheels than 32-spoke wheels.
NOTE: You can install push rims on 32-spoke rims, but GRIT recommends against it. The tabs should be evenly distributed between the spokes. Since most push rims have 6 tabs, wheels with spoke counts divisible by 6 are preferred!
Standard Freedom Chair Wheels are 559mm in diameter, max 26" x 2.25" with 36 spokes. Our hubs have a 15mm thru axle with 100 over-locknut-distance (OLD) and use an ISO 6-bolt disc mount for the couplings.
Step 2: Acquire the appropriate push rims. The push rims you'll need are 25" (559 mm), 6-tab push rims. Here is one third-party source, though others are available: https://enableyourlife.com/anodized-aluminum-6-tab-wheelchair-pushrim.asp
Step 3: Acquire the torque couplings. This is what connects wheels to the Freedom Chair and must be purchased through GRIT. To purchase the torque couplings, email support@gogrit.us with that request and we will send an invoice your way.
