How far can the M2601 go on a charge?

The 48V 7.8Ah battery is small for an e-bike, so expect modest range. Pedal-assist at low levels stretches it furthest; heavy throttle use drains it quickly.

Can I ride it without pedaling?

Yes. The four riding modes include throttle-only, so you can ride without pedaling, along with pedal-assist and plain manual cycling.

Is it legal on US bike paths?

Its 20 MPH top speed matches the Class 2 limit most US states use for throttle e-bikes. Check your local rules, since some paths restrict throttle bikes.

Does the battery come off for charging?

Yes, the 48V battery is removable, so you can carry it inside to charge if you park outside or live in an apartment.

What kind of terrain is it built for?

The 26 x 1.95 inch urban tires and rigid frame suit paved roads and paths. The 7-speed Shimano gearing helps on mild hills, but it is not a trail bike.
