Battery and Charging Details
A 432Wh pack for the long loop.
The 36V 9Ah pack stores 432 watt-hours in a rear-carrier casing and fills on the included charger. The management system guards against over-current and over-discharge, and cold weather trims capacity until the pack warms. Real-world range runs 37 to 50 miles depending on rider weight, terrain, and assist level. Charge soon after a ride rather than parking it warm and empty, and store it at room temperature when the bike will sit.
Daily Use & Care
Ten minutes a month keeps the 37-50 mile range where it belongs.
Wipe the frame, saddle, and wheels with a damp cloth after wet rides - no pressure washer, ever.
Check the folding latch is fully locked before every ride. A loose latch clicks under load - lock it and the noise disappears.
The tubeless tires hold pressure, so just glance at the tread for cuts and embedded debris.
Check the disc brake pads monthly; pads wear silently until they are gone.
Charge indoors at room temperature and unplug when the light turns green.
Keep the charge port covered between charges so moisture stays out.
Confirm the battery gauge shows the charge you expect before heading out.
Spin both wheels weekly and check that nothing rubs. A rubbing brake eats into the range.
