FAQ
How much does the Dahon Launch D8 Jaws Hinge version weigh?
12.1 kg, according to Dahon Hong Kong; Dahon's global site lists the 2024 model at 12.12 kg. Actual weight can vary slightly between batches and measuring tools.
What is the difference between the Jaws hinge and the standard hinge?
The difference is the folding hinge in the middle of the frame. Dahon's global site describes the Jaws hinge as the next evolution of Dahon's LockJaw technology, with sturdy teeth locking the hydroformed frame in place, and the comparison image on this page shows the Jaws hinge's quick-release lever under the frame rather than on its side. Dahon Hong Kong lists the same gears and weight for both versions, and Dahon's global page lists the Jaws hinge version at 82 x 39 x 62 cm folded, within 1-2 cm of the 82 x 38 x 64 cm used here; for the standard hinge see the Dahon Launch D8 (KBA083) 8 speed disc folding Bike.
Can I take the Dahon Launch D8 on the MTR?
Not when simply folded. MTR luggage must not exceed 170 cm in total length, width and height, with no side over 130 cm, and the Launch D8's official folded size adds up to about 184 cm. According to the Transport Department, a folding bike that does not comply may be taken in with the front wheel removed.
What rider height is the Dahon Launch D8 for?
Dahon's global page for the Launch D8 (Jaws hinge) currently lists a rider height of 150-190 cm and a 105 kg maximum rider weight (its archived 2024 page said 145-185 cm); Dahon Hong Kong does not publish these figures. If you are near either limit, please contact us before ordering.
