What does the rear differential do?

It lets the two rear wheels spin at different speeds in a turn, so the trike corners more smoothly than a fixed rear axle. That matters most on tight turns and uneven pavement.

Can I charge the battery indoors?

Yes. The battery is removable, so you can take it off the trike and charge it from a wall outlet inside. That helps if you park outside or in a shared garage.

How does it compare with a two-wheel e-bike?

It trades agility for stability. You get three wheels, an upright seated position and no balancing, but it is heavier, wider and slower to turn than an e-bike.

Does it fit through a standard doorway or gate?

A three-wheeler is wider than a bicycle, so check the width of gates, paths and storage openings before you buy. Tight spaces are harder to navigate than on two wheels.

Adults who want pedal-assist riding without balancing, including riders with balance or mobility concerns. It also suits errands and relaxed neighborhood trips.
