Bicycles & Electric Bikes Australia | NG Mobility

NG Mobility stocks two of Australia's most distinctive bicycle brands — DiroDi fat tyre electric bikes and YERKA anti-theft urban bikes. Whether you're commuting through Brisbane, riding beach trails, or looking for a bike that's genuinely difficult to steal, you'll find it here. All models are available online with fast Australian delivery, or test ride in our West End Brisbane showroom.

DiroDi Rover — Fat Tyre Electric Bikes

The DiroDi Rover Gen 6 is Australia's most versatile fat tyre e-bike. Road-legal 250W models are EN 15194 certified — no registration required in any Australian state. Off-road 1000W models are available for trails, farms, and rural properties. All models are dual-person rated with a 150 kg payload and up to 120 km range on a 48V 20Ah battery.

YERKA — Anti-Theft Urban Bikes

YERKA bikes feature a patented frame that splits to form its own lock — no external lock required. Designed for urban commuters who want a lightweight, theft-resistant ride without the bulk of a chain or D-lock.

All bikes are stocked and serviced at our West End Brisbane showroom. ReadyRide delivery ships DiroDi e-bikes fully assembled across QLD, NSW, ACT, and VIC.

Frequently Asked Questions

Find answers to common questions below

What conventional bicycles do you sell? ⌄

We stock YERKA bikes, which are built around an integrated anti-theft system. Rather than needing a separate lock, you secure the frame itself against a fixed object. It's a practical pick for commuters who lock up at the same spots regularly.

How does the YERKA anti-theft lock work? ⌄

The YERKA frame opens in a specific way so you can wrap it around a fixed object and close it, effectively using the bike as its own lock. It's designed to be fast to lock and unlock, so it doesn't slow down your commute.

Which YERKA model should I choose? ⌄

The V3 is the starting point if budget is a priority. The V4 Rigid steps up for everyday city commuting, and the V4 Suspension adds front suspension for a smoother ride on rougher streets. Compare the three on the product pages.

Do YERKA bikes ship Australia-wide? ⌄

Delivery for YERKA depends on your location. Check the options on the product page at checkout. Free standard shipping applies on orders over $150, and our 30-day return policy covers bikes that are unused and in original packaging.

What's the warranty on YERKA bikes? ⌄

Warranty is typically one to two years depending on the specific model. All NG Mobility purchases are also backed by Australian Consumer Law protections. Check the product listing for exact terms or message us to confirm before you order.
