Q
Which accessories are here, and how to choose for a rental?
This page covers power, inflation, locks and hooks, along with crossbars, ball fittings, bungee straps, bottle holders and crash-bar covers. Check the attachment point first. Choose by the job, not by fitting everything. For a rental, compare the sockets, exposed tubes and mirror fixings with what you plan to buy.
Q
Can I power a USB charger from the socket on my rental?
Check the socket first. Rental bikes in Vietnam rarely have a DIN (Hella) socket, so ask BigBike about power options before buying a plug-in charger. Kewig rates B8 at up to 22.5W USB-A and 30W Type-C, and B9 at Type-C PD 45W and USB-A QC 18W. Choose B9 for its cigarette-lighter socket. Avoid powering several heavy devices together.
Q
Does the tire inflator need a cigarette-lighter outlet?
Find the battery first. MP-1 takes power from the battery terminals, not a cigarette-lighter socket, so check access on the bike you ride. Kewig sets a 10-minute continuous-running limit, with a rest before further use. The lead has a fuse box, and automatic shutoff follows the pressure setting.
Q
Can I leave my helmet on the bike at a café stop?
For café stops, prefer supervised parking. CBK-4 is a helmet cable lock that secures the strap to the handlebar with a steel cable, slowing thieves rather than replacing supervision. Kewig sets the default code to 000. Change it on receipt. For bags, the CBK-2 handlebar hook clamps on, whereas CBK-3S wraps a webbing loop around a tube.
Q
How do I add mounting space on a scooter with covered bars?
On a plastic-covered rental scooter, HB6 adds an accessory crossbar at the mirror fixing without drilling, while HB4-L clamps an exposed handlebar. Measure exposed tube length. Kewig specifies a 1-inch ball system linking clamp base, arm and threaded adapter. A mirror riser bolt fits between mirror mount and mirror stem. Aluminum is softer than steel, so tighten gently. Check each mirror's thread size and direction.
Q
Straps, bottle holders, bar covers and warranty?
The BHT-1 crash bar guard takes scratches instead of the bar. It is not fall protection. The BD-1S bungee strap secures small bags to the seat or rack, loose ends kept away from the rear wheel. SHJ-6 holds a bottle on a tube, with no promise of a firm grip on rough roads. All Kewig items carry a 12-month defect warranty, excluding wear.
BigBike has operated since 2014 at 79/30/52 Au Co, Hoa Binh Ward, Ho Chi Minh City. Bring the bike for a DIN socket check, handlebar and mirror measurements, and a trial crossbar fitting. Listed dimensions do not confirm mounting space.
