More Ride Time, Same Frame
Why Parents Buy a Spare
Most parents replace this battery for runtime, not failure. The stock-equivalent pack suits short, supervised sessions, and families outgrow that within a season, a spare or upgrade pack means more laps without a mid-session recharge wait.

Description
This battery is built specifically for Stacyc bikes already running the XRT Moto conversion kit’s 350W motor system. It is not sold as, and shouldn’t be assumed to be, a direct replacement for a completely stock Stacyc’s original battery.
The supplier states this compatibility plainly: compatible only with Stacyc bikes using the XRT Moto conversion kit. If your bike is unmodified and stock, this isn’t the right part, check with us before ordering.
If the original battery won’t hold a charge at all rather than just draining faster than before, that usually points to cell health rather than a fit problem, this replacement resolves either case the same way a fresh OEM-equivalent pack would.

FAQ
- Will this work on a stock, unmodified Stacyc?
- No. The supplier states this battery is compatible only with Stacyc bikes running the XRT Moto conversion kit.
- What’s the battery capacity?
- 24V, 5.2Ah.
- How do I know if I need a new battery vs. a new controller?
- If the bike won’t power on at all even after a full charge, check the controller first. If it powers on but runtime has dropped noticeably, that points to the battery.
