Strider Balance Bike Parts & Conversion Kits

Strider builds pedal-free balance bikes, none of them powered from the factory. We stock two real electric upgrade paths plus the batteries, motors and wear parts that keep either one running. Shop below by product, or use the buying notes underneath to figure out which kit fits your kid’s Strider.
Which Strider Kit Fits Your Bike
Two genuine kits exist, and they’re not interchangeable. The 12″ kit is built specifically for the Strider 12 Sport and Pro models, it’s not stated to fit the Classic or the 2026 Comp, so check your exact trim before ordering. The 14″ kit is sized differently: it’s built for 125mm rear-fork push bikes, which covers Strider’s 14x-class frame and other push bikes sharing that fork spacing, not just Strider.Both run a 250W hub motor. Battery voltage differs by kit: the 12″ kit pairs with a 21V system (2.6Ah stock-equivalent, 4Ah upgrade available), while the 14″ kit’s battery voltage is listed inconsistently in our own supplier data (24V on the label, 2Ah in one spec line and 4Ah in another) — we’re treating that as unconfirmed until we get a straight answer rather than picking one.Browse Electric Conversion Kits for full kit details, Batteries & Chargers for spares, or Motors, Throttles & Controllers for individual replacement parts.
