Dahon MU LX 20inch Folding Bike PKA015

The Dahon MU LX (PKA015) is the 20-inch, 11-speed aluminium folding bike in Dahon's MU range. Dahon lists it at about 9.55 kg, with Dahon V-brakes, a custom 54T one-piece chainring, Schwalbe tyres and Ergon grips with bar ends. It puts 20" wheels and 11 gears on a folding bike under 10 kg, for riders who want bigger wheels and a wide gear range without the extra weight.

What Problem Does It Solve?

20" folding bikes have bigger wheels, but if the bike is heavy it is harder to carry upstairs or lift into a car boot. On Dahon's official figures, the 20" MU P10 in the same range weighs 11.9 kg with pedals, while the MU LX is about 9.55 kg — lighter even than the 16" MU SL D9 (9.88 kg). Jollymap's 2026 Dahon buying guide lists the MU LX as the "premium spec version" of the MU series.

Who Is It For?

• 20" riders who care about weight: about 9.55 kg (Dahon official).
• Riders who want a wide gear range: 11 speeds with a Dahon custom 54T one-piece chainring.
• Riders who care about hand and seating comfort: Ergon grips with bar ends and a Dahon custom ergonomic saddle.
• Maybe not for: riders who want disc brakes — see the Dahon MU P10 20 inch 10 Speeds Folding Bike - PAA003 (hydraulic disc brakes, 10-speed); riders who want a smaller fold — see the 16" Dahon MU SL D9 (PAA693) 9 speed folding Bike (75 × 35 × 62 cm).

11 speeds and 54T one-piece chainring

Dahon Hong Kong lists 11 speeds with a Dahon custom 54T one-piece chainring. Sources disagree on the drivetrain brand: Dahon Hong Kong's Chinese description says SRAM 11-speed, while its English description and Jollymap article 314 say Shimano 105. Components may vary by batch, so please contact us to confirm before ordering.

Dahon V-brakes

Dahon lists Dahon-specific V-brakes with Shimano Tiagra brake levers.

Schwalbe tyres, star-pattern wheels and Ergon grips

Dahon lists Schwalbe tyres, a Dahon star-pattern wheelset, Ergon grips with bar ends, a Dahon custom lightweight seatpost and an ergonomic saddle. The bar ends let you change hand position.

Folded size and public transport

The official folded size is about 81 × 38 × 65 cm, around 184 cm in total. MTR rules limit luggage to a combined length, width and height of 170 cm, so on official figures it is over the limit. On franchised buses, the Public Bus Services Regulations (Cap. 230A, section 14) only allow free carriage of items up to 5 kg and 0.1 cubic metres, which a folding bike generally exceeds; minibuses are not guaranteed either.

Jollymap Recommendation

If you want a 20" folding bike and often carry it upstairs or into a car boot, the MU LX's official weight of about 9.55 kg is its biggest strength. If braking in the rain and on descents matters more, consider the MU P10 with hydraulic disc brakes. Because drivetrain brand information is inconsistent, chat with us before ordering to confirm the current specification, or message our Facebook page.
