Fitment checked, not guessed
Every listing states the exact bike model it fits — and when it won’t.
Bench-tested before listing
Controllers and conversion kits are tested for heat and power draw before they go up for sale.
Install notes with every kit
Wiring diagrams, torque specs and a parts checklist — not just a bag of parts.
Support that actually helps

Most “universal fit” listings aren’t.
Most of what’s sold as balance-bike parts online is dropshipped from the same handful of factories with a new label slapped on. Dropout spacing, controller voltage and connector types change between a Strider 12 Sport and a Strider 12 Pro, let alone between brands — a part that bolts onto one won’t always bolt onto the other.
Every listing on this site states the exact bike model, wheel size and dropout spacing it’s built for, and flags it plainly when our own supplier data is inconsistent or unconfirmed rather than picking a number and hoping. Controllers and conversion kits get bench-tested for heat and power draw before they’re listed for sale.
