Aceoffix D10 18inch 355 10 speed Carbon Fork Folding Bike

The Aceoffix D10 is an ultralight 18" triple-folding bike built for riders who want a Brompton-style fold with disc brakes and a wider gear range. A 6069 aluminium frame paired with a T800 carbon fork brings the weight down to around 8.5kg, while a 10-speed external derailleur and full hydraulic disc brakes give it more range and stopping power than most compact folding bikes at this weight.

The Problem It Solves

Classic triple-folding bikes with rim brakes lose stopping power fast in Hong Kong's frequent rain, and their single-speed or narrow-range gearing struggles on the ramps up to footbridges and MTR exits. The D10 keeps the compact triple-fold format but adds a wide-range 10-speed drivetrain for hills and full hydraulic disc brakes that stay consistent when wet - without the weight penalty you'd expect, thanks to the carbon fork and aluminium frame.

Who It's For

Best for riders upgrading from an entry-level folding bike who want disc brakes and more gears without stepping up to a full-suspension bike. If your priority is the lightest possible weight for a short, flat commute and you don't need 10 gears, the simpler 5-speed Aceoffix C5 16inch 349 5 speed Carbon Fork Folding Bike is lighter - see the comparison below.

Carbon fork and aluminium frame keep it light

A T800 carbon fibre fork paired with a 6069 aluminium frame brings total weight to around 8.5kg - light enough to carry up a flight of stairs without strain.

10-speed drivetrain for a wider gear range

A 50T crankset with a close-ratio cassette gives more usable gears than a typical single-speed or 3-speed folding bike, which helps on footbridge ramps and MTR exit slopes.

Full hydraulic disc brakes

Hydraulic disc brakes need less hand force and keep more consistent stopping power in wet weather than the rim brakes found on cheaper folding bikes - relevant given Hong Kong's humidity and frequent rain.

18" (355) wheels for a smaller folded package

The 355 wheel size keeps the folded bike compact for storage in a small flat or office, while still rolling better than the smallest 16" wheel formats.

Jollymap's Advice

Aceoffix bikes use a Brompton-style frame layout, and some Aceoffix and third-party accessories (racks, easy wheels, hinge clamps) are designed to be compatible across models - but exact fit can vary by production batch. Not sure an accessory fits your D10? Contact us before you buy. Send us your bike's colour/batch and a photo through the "Talk to us" button on our online store or our Jollymap Facebook page, and we'll check fit for you. Jollymap also stocks the matching Aceoffix D10 rear rack with easy wheels (18 inch) for adding a rear carrier.

FAQ

Where is Aceoffix made?

China. Aceoffix is a mainland China-based brand, and the manufacturer's product listing states Zhejiang, China as the place of origin.

What's the difference between the Aceoffix D10 and C5?

The D10 has larger 18" wheels, 10-speed gearing and full hydraulic disc brakes, aimed at riders who want more gears and stronger wet-weather braking. The C5 has smaller 16" wheels, simpler 5-speed gearing and front and rear rim brakes (caliper), and is lighter. See the comparison table above.

Can the Aceoffix D10 be modified or upgraded with aftermarket parts?

Yes - being a Brompton-style folding frame, many riders fit third-party racks, easy wheels, mudguards and hinge clamps. Jollymap stocks the matching Aceoffix D10 rear rack with easy wheels (18 inch) and other Aceoffix accessories; contact us with a photo of your bike before ordering to confirm fit, since exact mounting points can vary by production batch.

How much does the Aceoffix D10 weigh?

Approx. 8.5kg, based on the manufacturer and distributor listings we cross-checked. Actual weight can vary slightly depending on colour and exact configuration. Jollymap weighed it at about 8.7kg with pedals - see Jollymap's Aceoffix D10 review (in Chinese).

Does the Aceoffix D10 have a mudguard or rear rack fitted as standard?

No rear rack as standard. The base spec covers the frame, drivetrain and brakes; a matching rear rack with easy wheels is sold separately - see the Aceoffix D10 rear rack with easy wheels (18 inch).

What size wheels does the Aceoffix D10 use, and how does that affect the fold?

18" (355) wheels - slightly larger than the C5's 16" (349) wheels, which gives a slightly larger folded package but a smoother ride over uneven pavement.

Is the Aceoffix D10 suitable for hilly commutes?

Suitable for short inclines. The 10-speed drivetrain with a close-ratio cassette gives a wider gear range than single-speed or 3-speed folding bikes, which helps on footbridge ramps and short slopes, though it is not designed for sustained steep climbing like a full-size road or mountain bike.

Are Aceoffix D10 parts compatible with Brompton?

Partly. Aceoffix's frame layout is closely modelled on Brompton's, so some accessories overlap. Exact compatibility can vary by part and production batch - send us a photo before buying an accessory and we'll confirm.

Specifications and components follow the manufacturer's latest release and may change without notice. If in doubt, please contact us to confirm before ordering.
