Tino Fa'asuamaleaui'sNRL PlayerTaking my bike to training is definitely way more convenient, getting to training quicker, it’s a bit more fun and a bit more freedom in the mornings. I guess, seeing the sunrise, having my music in, and just relaxing before a big training sesh, definitely helps, and gets my day started well. I’m loving it.

Beaver FlemingPro SkateboarderAs a skater, I’m always trying to find new spots. But sometimes it’s hard skating around town all day long. Thankfully I got the Ampd Bros bike so I can get from spot to spot and have energy to get some lines.

Logan MartinPro BMXMy favourite thing about this bike is the space. You know, I can fit my wife and my kid on it. We can go cruising along the beach, along the pathway. A few things that set my bike apart from other bikes I’ve tried in the past. For one is the power and speed it gets to, the comfortability and the range it gets as well. It’s unlike any other.

Lee BesserCinematographerI’m not exaggerating when I say it’s completely changed the way I go about my day. Now I live in the city, I’ve got a car, but between the tolls, the cost of parking, traffic, I’m finding myself leaning on the bike more and more. I often find it’s cheaper, quicker and more importantly more fun to use the bike.

Arisa TrewPro SkateboarderMy favourite accessory for the bike is the surf rack because it makes going to the beach or skatepark so much easier because I can put my surfboard or skateboard on it.

Size Guide

Do your bikes come assembled?
Bikes ordered online arrive in a box with about 20% of assembly required upon unpacking. We have detailed assembly videos on our YouTube channel and Tutorials page. In-store purchases can be assembled for a fee.
Are e-bikes legal?
Yes — e-bikes are legal in Australia. To be road-legal they must be pedal-assist only, not exceed 25km/h assisted, and have a max continuous output of 250W (some state exceptions apply). Throttle-only and higher-powered devices are restricted to private property. Always check your local road authority.
How long is your warranty?
Our adult range is backed by a 2 Year nationwide warranty, and kids' bikes by 1 Year. See our warranty page for full terms.
How much is delivery?
FREE for orders over $100 in Australia, or a flat $8.95 under $100. Express and shipping insurance are available at checkout. A $199 fee applies to oversized motorbikes to WA, TAS and NT.
How long will it take to receive my order?
Standard shipping is normally 3-5 days. Bulky freight like e-bikes averages 5-10 days to major cities, and 14+ days to rural areas, NT, WA or TAS.
Can I add a throttle to my bike?
For off-road/private property use, yes — throttles are available as optional accessories. They are not legal on public roads, which is why they aren't included with our bikes.
