What problem does it solve?
Many riders worry that a folding bike's hinges make the frame feel less solid. Jollymap's Vigor D9 review video points to its dolphin frame design as the reason for its high stiffness. Add 9 speeds and disc brakes for flat roads and climbs, plus a pump inside the seatpost, so you do not need to carry a separate pump when a tyre runs low.
Who is it for?
The Vigor D9 suits riders who mainly use cycle tracks and city roads, with some hills, and want a stable-feeling frame. If you take the bike on the MTR every day or often carry it up and down stairs, a 20-inch folder may not be ideal; consider a 16-inch bike such as the 9-speed Dahon MU SL D9 (PAA693) 9 speed folding Bike. Dahon Hong Kong does not publish a maximum load or rider height for the Vigor D9, so if you are near the usual limits of a folding bike, please contact us before ordering.
Dolphin-shaped aluminium frame
The Vigor D9's top tube curves in a dolphin shape and carries the "Vigor d9" name. Jollymap's review video focuses on this "dolphin frame design", noting the high frame stiffness it brings for riders who want stability.
9 speeds with disc brakes
The official specs list 9 speeds, and the product name marks it as the disc brake version. The official photos show a Dahon trigger shifter printed "9-SPEED" and a rear disc brake. Shift to an easier gear on climbs, with enough range for everyday riding.
Pump inside the seatpost
The official photos show "SeatPump" and "PUMP INSIDE" printed on the seatpost, with the pump stored inside; Jollymap's video also tests this built-in pump. The photos also show a kickstand. Fittings may vary between production batches; please contact us before ordering if you need to confirm.

Jollymap's advice
If you value a stable frame and like having a pump on board, the Vigor D9's dolphin frame and seatpost pump are genuinely useful; if you mostly ride to the MTR or carry the bike often, a 16-inch folder is more convenient. Not sure which suits your height, storage space or daily route? Chat with us or message our Facebook page before ordering, with your height, weight and where you will store the bike.
