Jun 2020

Price: $1499.00 | Model Year: 2020 | An affordable but refined electric cargo bike with custom 22

Observations
  • An affordable but refined electric cargo bike with custom 22" x 3.0" tires that improve stability and comfort while still keeping the cargo holds low and easy to load. Approachable but stiff mid-step frame comes in three beautiful colors. Reflective tires and quality integrated lights help keep you visible and safe

  • Powerful fat-bike rated 80nm geared hub motor provides excellent power for starting, hauling gear or passengers, and climbing. Steel torque arm spreads motor forces into frame instead of chewing up the dropouts. Respectable 11-34 tooth cassette is nickel coated for durability, upgraded Shimano Acera derailleur should be reliable, and is protected by a steel derailleur guard.

  • Extra-strong steel double-leg kickstand keeps the bike stable for loading and unloading, wide plastic fenders keep you dry, aluminum chain guide protects the chainring and your pant legs or dress ends, neoprene slap guard protects the paint and reduces noise from chain bounce. Lots of adjustability for fit including telescoping seat post, tool-free adjustable stem, and swept-back handlebars.

  • No suspension fork, but the high-volume tires and ergonomic grips improve comfort while reducing weight, cost, and frame flex. Mostly sold direct-online, but Rad has three physical locations in US, Canada, and Europe, as well as mobile delivery vans for setup and service. Basic shifter and grayscale LCD that's not removable, but it does have a USB charging port built-in
