FingerTech Hubs and Foam Wheels

(1 customer review)


We now stock Repeat Eco Hubs compatible with these foam wheels – two grub screws for extra strength! Foam wheels are a great choice for beetles because they absorb impacts and save your drive motors from stripping teeth. Metric sizes below. We’re stocking so you won’t have to order from Canada and pay international shipping and import taxes! For extra grip, try coating the tyres (optional: in a few layers of rubber cement and then) a few layers of liquid latex.

With Twist Hubs you can easily and securely mount these foam tires to your robot by twisting, no dealing with circlips! They’re made from anodized 6061 aluminium for high strength and low weight and have a 4mm bore to fit our 22mm motors or standard 25mm beetle motors! We now stock 6mm bore for Mega Sparks & Repeat Max. The hub is secured to the motor shaft by a strong setscrew (included) – this requires a 2mm hex key. More info on the FingerTech website.

Twist Key: Use our laser cut nylon twist hubs key, 3D Print your own or use needle nosed pliers or similar to twist on. Note – there will be some burn marks on our twist key from the lasering process.

    These are brilliant – I’d read that some people drill the set screw out to a larger diameter, but as standard on a 4mm D shaft they held perfectly even without Loctite. They’re also really tough as took a direct hit on the hub and although it broke, the motor was fine. I would recommend to buy the twist hub key as it makes taking wheels on and off a lot easier.
