Worth Keeping a Spare
A Small Part That’s Easy to Lose Track Of
A charger is one of the easiest parts to misplace between riding seasons. A spare means a dead cord or a lost charger doesn’t take the bike out of commission for a shipping cycle.

Description
A replacement or spare charger built specifically for the Strider 12in electric conversion kit’s 21V battery system. The supplier is explicit that this charger is not compatible with other voltages or bike systems, so it’s not a universal option for other kits in this catalog.
Charging rate is stated at 2A. Exact time to a full charge depends on which 21V battery you’re running, the stock-equivalent 2.6Ah pack or the 4Ah upgrade pack, neither of which has a stated charge time from the supplier.
This is sold as a standalone charger, separate from the full 12in kit. A parent replacing a lost or damaged charger, or keeping a spare on hand, would order this on its own.
FAQ
- Can I use this on the 14in kit’s 24V battery?
- No. The supplier states this charger is for 21V systems only and isn’t compatible with other voltages.
- How long does a full charge take?
- Not stated by the supplier beyond the 2A charging rate. Exact time depends on which 21V battery pack (2.6Ah or 4Ah) you’re charging.
- Does it include a voltage adapter?
- Not stated. Treat this as the standard plug only, matched to the 12in kit’s factory connector.
- Is this the charger that ships with the full kit, or a separate purchase?
- This is sold separately as a replacement or spare charger.
