Bike Lock Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Master Lock is the best-performing bike lock brand in July 2026, moving 21,000 units across 4 ASINs for 43.8% of Top 10 volume. Sportneer follows with 13,000 units (27.1%), ahead of Weogine on 4,000 units (8.3%).

With 6 brands splitting the Top 10 and 79.2% of volume sitting with three of them, this is a concentrated shelf — the leaders hold multiple listings or one very high-velocity ASIN, so a new entrant competes against established review moats rather than an open field. Average selling prices among the leaders run from $9.99 to $19.99, which frames the price band a competing listing has to justify.

Based on July 2026 data, this shortlist surfaces the two kinds of ASIN worth keeping an eye on — the ones that just broke into the Top 10, and the ones growing fastest month over month. Specifically, one ASIN forced its way in: B0000D1E3S booked 7K units at $12.92, with ▲ 250.0% MoM change. On the growth side, B076TZ8D7G leads positive momentum with ▲ 100.0% MoM growth on 2K units, with B0G484HKCY close behind at ▲ 100.0% MoM on 400 units.

The two signals carry different weight. A fresh entrant means share has already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date. A steep growth rate works as the earlier warning: it marks demand that is still compounding, usually a month or two before the ranking catches up to it.
