How fast does the Spark Max go?

Spark claims a top speed of up to 38 MPH with the dual-motor setup. That is far above the 20-28 MPH limits most places set for e-bikes, so check local rules before riding at full speed.

How far can it go on a charge?

It uses a 52V 20Ah battery, a large pack for this class. Range depends heavily on speed, rider weight and terrain; running near the 38 MPH top speed will drain it much faster than cruising at lower assist levels.

Is it good for hills?

Spark claims 45%+ hill-climbing performance from the dual motors. That is well beyond typical single-motor fat-tire bikes, though steep climbs will still draw the battery down quickly.

Can I ride it on trails and sand?

The 20x4.0 all-terrain tires and full suspension are built for city streets, trails, sand and snow. Fat tires float better on soft ground, but deep sand and mud still demand low assist and steady throttle.

Do I need a license to ride it?

At up to 38 MPH it exceeds e-bike legal limits in most US states and many countries, so it may count as a moped or motorcycle there. Check your local rules on speed, licensing and where it can be ridden.
