Unlock your Fatboy V3 rear rack for child seats and more.
The Fatboy Rear Rack Adapter V3 is a custom-designed adapter made specifically for the Fatboy V3 rear cargo rack. It turns the rack into a mounting platform for a range of accessories, most notably the Thule Yepp 2 Maxi child seat, so your Fatboy can go from solo cruiser to school-run and weekend family ride.
Built by Fatboy for Fatboy, it bolts straight onto the V3 rack with no modification and installs quickly and easily. If you already run the V3 rear rack on your Scrambler, Bagus, DNA or Harlem, this is the piece that makes it far more versatile.
About Fatboy Bikes

Known for its fat tyre e-bikes and signature two-seater design, Fatboy builds bikes and accessories for Australian riders and conditions. Fatboy is our best-selling e-bike brand at Twelve Board Store, and we stock Fatboy spares and accessories in-house in Melbourne.

FAQs
Will this fit my Fatboy?
It fits the Fatboy V3 rear cargo rack, which suits the Scrambler, Bagus, DNA and Harlem V3 models. If your bike doesn't have the V3 rack fitted, you'll need that first. Not sure which rack you've got? Send us a photo and we'll confirm.
Does it fit the older V2 rack?
No. This adapter is made for the V3 rack. Fatboy makes a separate Rear Rack Adapter for V2 racks, so check your rack version before ordering.
Can I fit a child seat with this?
Yes. It's designed to mount the Thule Yepp 2 Maxi child seat to your Fatboy. Always follow Thule's child weight and age limits and stay within the rack's 30 kg maximum load.
Is it hard to install?
No. It's a quick bolt-on job with basic tools. If you'd rather not do it yourself, drop into our Richmond store and our team can fit it for you.

Burton AK Acamar 3L Goretex jacket
I managed to steal this in-season 3L Gore jacket for half its retail and it took no time for delivery. Now I just have to wait till January to test it in some J-pow conditions. Awesome service from the team at 12 :-)

Pint-S thoughts
I've had my new Pint-S now for a week and put about 11 klms on it so far due to a fair bit of rain. The battery is now at 62% and top speed of 16kph as I find 12-15 very comfortable and have no intention of hurting myself any sooner than I have to.
The treaded tire gives more confidence for sure off of the pavement which I do about 50%.
I like the curved foot pads as I like a wide stance and my feet feel more planted than on the Pint. The Fender is also almost a must for me now that I see the difference of gravel and dirt not covering the footpads anymore.
Twelveboard store was very helpful and friendly with the purchase as well.

Why Buy from Twelve Board Store
Twelve Board Store has been riders selling to riders since 2013. We are not a generic retail chain — we are a specialist board sports retailer built around genuine product knowledge, real rider experience and the kind of after-sales support that only comes from a team that actually uses the gear they sell.
Every brand we stock, we ride. Every recommendation we make comes from real experience — on the mountain, in the park, on the street, and on the road. When you call us, you talk to someone who has been on a snowboard at Hotham last weekend or a skateboard in the carpark this morning. That is the difference between buying from Twelve and buying from a warehouse with a website.
We offer services that no online-only retailer can match. Our in-store workshop handles snowboard waxing and tuning, boot heat moulding, electric skateboard and e-bike repairs and assembly, and warranty support handled in-house rather than shipped offshore to a call centre. If something goes wrong with your gear, we fix it. If your boots don't fit, we sort it. If you ordered the wrong size, we swap it — no questions asked.
Our showroom at 435A Bridge Road Richmond stocks the full range across snowboards, bindings, boots, skateboards, longboards, electric skateboards, e-bikes, outerwear and accessories. We offer free shipping Australia-wide on orders over $89, AfterPay and Zip for flexible payment, and fast dispatch so your gear arrives when you need it.
Over a decade in business. More than 1,000 reviews. The most trusted specialist board store in Melbourne. If you need advice before you buy, call us on 03 9421 2293, visit us in-store, or contact us online — we'll get you sorted.
