Key Features

A 250W brushless motor (600W for the US) delivers smooth, steady acceleration for errands and daily rides.
48V 21Ah Battery
The 48V 21Ah pack stores 1,008 watt-hours, so a charge covers the errand loop and then some.
25-37 Mile Range
A full charge carries you 25 to 37 miles. Rider weight, terrain, and assist level all move that number.
14-inch Pneumatic Tires
Fourteen-inch pneumatic tires roll smooth and cushion the ride, filtering the small vibrations of city streets.
Double Disc Brakes
Double disc brakes keep stops short and predictable, with lever effort that stays light.
Dual Suspension
Dual suspension soaks up cracks and cobblestones, keeping the saddle and the hands comfortable.
Ride Seated
A seat lets you sit back for the errand run, so grocery runs stay comfortable.
Basket Included
A basket is included, so you can carry groceries and daily items without a backpack.
Foldable Frame
The aluminum-alloy frame folds down in one step for the trunk, the train, or a closet corner.

Battery and Charging Details
A 1,008Wh pack for the errand loop.
The 48V 21Ah pack stores 1,008 watt-hours and fills in about 5 to 8 hours on the included charger. The management system balances the cells and guards against over-current and over-discharge, and cold weather trims capacity until the pack warms. Real-world range runs 25 to 37 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 25-37 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.
Check the pneumatic tires weekly and keep them in the recommended pressure range. A soft tire drags and trims range.
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.
