Impac by Schwalbe 16 x 1.75-2.25 SV (Schrader Valve 35mm)

Impac by Schwalbe Tube — 16 × 1.75–2.25, Schrader SV 35 mm

Reliable, no-fuss butyl tube sized for 16″ kids’ bikes, BMX and compact folders. The 35 mm Schrader valve is the standard car-type valve — easy top-ups at any servo and a perfect match for rims with the larger valve hole.

Fit Notes

Lightly inflate before installation, confirm rim tape covers all spoke holes, and check both beads for pinches. Not suitable for 16 × 1-3/8″ (ETRTO 349) wheels such as Brompton — choose a 349-specific tube for those. If your rim is drilled for Presta (~6 mm), pick the Presta version rather than enlarging the hole.
