Product Description
The ultimate versatile solution for DIY e-bikes! Our 36V 14Ah "Frog" Battery mounts securely to your seat post, making it compatible with almost any bicycle geometry—even those without bottle cage mounts.
🏆 Universal Seat Post Mount
This battery comes with a clamp-on mounting base that attaches directly to your seat post (27.2mm - 31.6mm).
It's the perfect choice for:
- DIY Conversions: Turning a standard mountain bike or folding bike into an e-bike.
- Full Suspension Bikes: Where there is no space on the downtube.
- Vintage Replacements: Fits older models from FreeGo (Hawk/Eagle), Cyclamatic, and Viking (Check dimensions).
⚡ Panasonic Power Upgrade
Old Frog batteries were heavy and weak (often Lead-Acid or cheap Lithium). We rebuilt this classic shape using modern Panasonic INR18650-3500mAh cells.
Result: 14Ah (504Wh) capacity in a lightweight pack (approx 3.5kg). That's enough for 35-50 miles of riding!
📏 Dimensions & Fitment
Size: 247mm x 147mm x 150mm
Includes the battery, the mounting controller box (base), and keys. The base clamps onto the seat tube under your saddle.
