Important things you should know about these cargo bikes.

• Most can be outfitted with an electric assist motor and be street legal and not require a motorcycle license (check local laws first, though). Some manufacturers, or their authorized retailers, will sell you and install the electric assist motor.

• They are heavy - you can most likely not bring these up many stairs without assistance.
• They are bulky - you will need a good space for these near ground level. If you have a gangway, ensure you can walk beside the bike as you move through it.

• Most, if not all, of these cargo bikes CANNOT be brought onto light rail, rapid transit, or commuter trains (e.g. Caltrain-California, Metra-Chicago), mainly because of their abnormal length. Amtrak, or other long-distance trains where passengers typically have to reserve a space for their bicycle (i.e. buy an extra ticket) may still accept them alongside normal cargo.
• Richard Masoner of Cyclelicious explains that the Caltrain length limit is 80 inches and reports seeing tandem and child trailers aboard.
