A compact 36V 10.4Ah (374Wh) bottle/Polly-style battery that bolts directly to the standard bottle-cage mounts on the down tube, giving a tidy factory-look conversion without a bulky rack or frame case. Built with 18650 cells and a 15A BMS, with a power button, charge LEDs and a keyed slide-lock base for quick removal. Its light weight and slim shape make it ideal for road and city conversions where range demands are modest. Supplied with the mounting base, a 42V 2A charger and two keys. As a bare battery it has no throttle rating — paired with a 250W pedal-assist conversion the complete bike is road-legal in the UK (EAPC). Note this lower-current pack is not suitable for high-power off-road builds.

No. EAPC (Electrically Assisted Pedal Cycle) e-bikes are legal on UK roads without a licence, insurance, or registration, provided the motor assists only while pedalling and is limited to 250 W / 15.5 mph.
Range depends on the battery size, rider weight, terrain, and assist level. Check the specific product specification for its stated range; typical figures are 40–120 miles per charge.
Most batteries charge in 3–6 hours from flat using the supplied charger. Fast-charge options (where available) can halve this time.
Yes. Our bikes carry an IP rating (see spec tab) and are designed for UK weather. Avoid submerging the battery or motor. Dry and lightly oil the drivetrain after wet rides.
