Amp'd Bros ACE-X Adventure S5 Off-Road Electric Bike
The ACE that started Australia's fat-bike wave, Series 5, in its factory off-road build. Same plush two-up seat, Maxxis all-terrain rubber and big 960Wh Samsung-cell battery as the road model, but with the power unleashed and no throttle restriction. Built for farms, private tracks, beach houses and big properties where you want to roll without pedalling and without a speed cut-out.
Off-Road and Private Property Use Only
This is Amp'd Bros' factory off-road model. It does not meet the EN15194 e-bike standard, it is not a road-legal electric bicycle, and it can't be ridden on roads, footpaths, bike paths, shared paths, car parks or anywhere the public has access. Ride it on land you own or land where you have the owner's permission. Amp'd Bros asks every off-road owner to complete its off-road acceptance (you must be 18 or over), and the bike can't be converted into a road-legal model later. If you want to ride on the street, choose the ACE-X Adventure S5 Road Legal version instead.
Why You'll Love It
- Unrestricted: factory off-road output (above the 250W road rating) with no throttle limit, so you can cruise without pedalling.
- Goes the distance: 48V 20Ah battery on premium Samsung 21700 cells, removable for indoor charging.
- Pulls hard: Bafang rear hub motor with 80 Nm of torque for sand, grass and steep driveways.
- Stops when it counts: 2-piston hydraulic discs on oversized 203 mm rotors.
- Grips everywhere: Maxxis all-terrain 20 x 4" fat tyres float over loose ground.
- Connected: Ampd Bros GO App with live 4G GPS tracking, digital key, remote lock and alerts, ride stats and parental controls to tame the power for younger family members.
- Built for two: ribbed two-up comfort seat, adjustable front suspension and a 180 kg max load.

Frequently Asked Questions
Can I ride the off-road ACE-X Adventure on the street?
No. The off-road model isn't an EN15194 e-bike, so riding it anywhere the public has access can mean fines, seizure of the bike and no insurance cover. It's for private property only. For road and bike path riding, choose the Road Legal version.
Can it be made road legal later?
No. Amp'd Bros builds the road and off-road models differently at the factory, and limiting the speed or power afterwards doesn't make an off-road bike compliant. Choose the right version up front.
How far will it go on a charge?
Amp'd Bros rates the Adventure at up to 80 km in its road configuration. Using the unrestricted throttle and higher power off-road will use more battery, so expect less range the harder you ride it.
Can I limit the power for kids or new riders?
Yes. The GO App includes parental controls to adjust power and speed restrictions. Amp'd Bros recommends anyone under 16 is supervised by an adult on high-powered off-road bikes.
What warranty does it come with?
Amp'd Bros covers its adult e-bikes with a 2-year Australian warranty that includes the battery. Twelve Board Store is an authorised Amp'd Bros dealer.

Let customers speak for us
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.
