What problem does it solve?
Want a folding bike that looks good and rides comfortably without giving up easy storage? The Boardwalk D7 uses a Cr-Mo steel frame. Jollymap's Dahon buying guide describes the Boardwalk series as having slim steel tubes with good shock absorption and a classic British retro look; Cr-Mo is slightly heavier than aluminium but tough, with a comfortable ride. Seven speeds handle cycle tracks and city roads, and it folds away to save space at home.
Who is it for?
The Boardwalk D7 suits riders who enjoy weekend cycle-track rides and city trips and care about looks and ride feel. If you want more gears or a lighter bike, compare the other models below; if you take the bike on the MTR every day, a 16-inch folder is more convenient. Dahon Hong Kong does not publish a maximum load, rider height or folded size for the Boardwalk D7, so if you have specific needs on height, weight or storage space, please contact us before ordering.
CR-MOLY steel frame
Dahon Hong Kong lists the frame as CR-MOLY (chromoly) steel. Jollymap's buying guide notes that Cr-Mo is slightly heavier than aluminium but tough and shock-absorbing, with a comfortable ride. The Boardwalk D7 weighs 11.9 kg per Dahon.
Classic retro looks
The official photos show a brown saddle and tan-wall tyres, with a silver handlepost, seatpost and chainring guard and "Boardwalk" lettering on the frame. Red, yellow, dark green and grass green all share the same retro details.
7 speeds with V-brakes
The official spec is 7 speeds, enough for flat roads and gentle slopes on cycle tracks and in the city. The official photos show V-brakes front and rear. Fittings may vary between production batches; please contact us before ordering if you need to confirm.

Jollymap's advice
If you like a retro look and a steel-frame ride and mainly use cycle tracks and city roads, the Boardwalk D7 is a great fit; if you mostly ride to the MTR or carry the bike often, a 16-inch folder is more convenient.

FAQ
How much does the Dahon Boardwalk D7 weigh?
This HAC072 weighs 11.9 kg per Dahon. Dahon Hong Kong also lists another Boardwalk D7 (in sky blue, olive green, pink and others) at about 12.5 kg with pedals – a different batch from the red, yellow, dark green and grass green bikes on this page.
Is the Boardwalk D7 frame aluminium or steel?
Steel. Dahon Hong Kong lists the frame as CR-MOLY (chromoly) steel, not aluminium. Cr-Mo is slightly heavier than aluminium but tough, with a comfortable ride.
What is the difference between dark green and grass green?
They are two official Dahon colours. Dark green is a deep forest green, which Jollymap's buying guide also calls "post-office green"; grass green is a lighter, greyish olive. Specs are the same, so choose by taste – contact us before ordering if you would like to see real photos.
Boardwalk vs Speed series: what is the difference?
Both use Cr-Mo steel frames. Jollymap's buying guide notes that the Speed series has sportier, speed-focused geometry, while the Boardwalk is about retro looks. Model for model, the Boardwalk D7 is 7-speed at 11.9 kg; the Speed P8 is 8-speed at 12.7 kg with a 105 kg maximum load.
Boardwalk D7 vs D10 and D18: what is the difference?
Mainly gearing and spec. According to Jollymap's buying guide, the Boardwalk D10 (HAC003) is 10-speed at about 11 kg; the Boardwalk D18 (HAC083) has Shimano Sora 18 speeds, a 4130 Cr-Mo frame with an aluminium fork, at about 11.7 kg. The D7 is 7-speed at 11.9 kg, the simplest set-up.
How big is the Boardwalk D7 folded? Can I take it on the MTR or a bus?
Dahon Hong Kong does not publish the Boardwalk D7's folded size. The MTR limits luggage to a total length, width and height of 170 cm; franchised buses generally only allow items within 5 kg and 0.1 cubic metres (Public Bus Services Regulations, Cap. 230A, section 14), and minibuses are not guaranteed. If you plan to take it on public transport, contact us before ordering for the actual folded size, and check the latest rules with the operator before you travel.
What is the Boardwalk D7's weight limit and rider height?
Dahon Hong Kong does not publish them. If you are near the usual limits of a folding bike, please contact us before ordering.
Where can I buy the Dahon Boardwalk D7 in Hong Kong?
It is available at the Jollymap online shop and store. To confirm colours or batch fittings before ordering, chat with us online or message our Facebook page.
