Not only are they designed to carry heavy cargo loads, but they’re also built in the US by Montana-based Coaster Cycles. The electric mail bikes are built on the Freighter AW platform, which can be modified for various types of commercial e-cargo bike applications.
Technically it’s an electric cargo tricycle, but it almost looks more like a cargo van than a bike.
The giant rear cargo box provides 72 cubic feet (over 2,000 liters) of space for mail, and the bike can hold up to 400 lb. (181 kg) of cargo. Hydraulic disc brakes help bring all of that weight to a stop quickly and safely.
Powering the bike is Bosch’s Cargo Line e-bike drive system, which supplies the rear wheels with 85 Nm of torque. The drive system is paired with a 500 Wh battery to power the mid-drive motor, though multiple batteries can likely be swapped in to extend the range.
