Product Description
Double the range of a standard battery! This 36V 25Ah Polly Battery packs a massive 900Wh of energy into a sleek downtube case. Perfect for long-distance touring and delivery riders.
🏆 The "Polly" Upgrade (21700 Tech)

- Bafang BBS01 (250W-700W): Ride 100km+ on a single charge.
- Tongsheng TSDZ2: The perfect companion for torque-sensing mid-drives.
- Hub Motors: Any 36V rear or front hub motor kit.
