Biky vs woom: kids bikes compared by size

This page puts each Biky Air model next to the woom model for the same wheel size: regular price, published weight, brakes, gears, chain cover and rider height, as published on woom.com on November 1, 2026. The notes at the end say where every number comes from. Prices and specifications change; the product pages are the live source.

Both brands build aluminum bikes for children with child-sized levers and low weight. The differences that matter to a parent sit in three places: price, the coaster brake on the 14 inch woom in the U.S., and the chain cover on the single-speed Biky models. Biky keeps its prices down by selling direct, with no stores and no dealer network, while building every Air on a 6061-T6 aluminum frame with Tektro brakes.
