What you can do with an e-cargo bike

An e-cargo bike is a regular bike with two changes: a longer or wider frame for carrying things, and a pedal-assist motor that helps with hills and loads. People who try one find it covers most of the trips they'd assumed required a car — daycare drop-off, the weekly grocery run, hardware store hauls, beach day, the occasional Costco trip.

The main types

• Long-tail (Tern GSD, Yuba Spicy Curry, RadWagon): A standard frame stretched to fit two kids on the back rack, plus panniers below. Most popular for family use.
• Front-bucket (Urban Arrow, Bullitt, Riese & Müller Load): A box in front of the rider; kids face you. Excellent for cargo and very young children.
• Midtail (Tern HSD, Specialized Globe Haul): Smaller and easier to park than a long-tail. One kid plus groceries.

What they handle

• 100+ pound loads (kids and groceries) without strain
• Hills that would be punishing on a regular bike
• 30-50 mile range on a charge
• Most short-to-medium errands more pleasantly than driving them, since you skip parking

How to try one without buying

• Community Pedal Power (Cambridge) runs a free e-bike library — borrow one for a weekend.
• CargoB rents e-cargo bikes by the minute around Greater Boston.
• Most local bike shops do test rides; some run demo days.

A few practical realities

• Parking: Long-tails and front-bucket bikes don't fit in standard bike racks. Plan for street parking with a heavy lock, or look for bike corrals.
• Range: A typical day uses 10-30% of the battery. Most people charge once or twice a week.
• Price: New e-cargo bikes run $3,000-$8,000. The used market is solid; bike libraries and rentals are how most people figure out which type fits before buying.
