Pros

  • The torque sensor transforms the ride versus the old cadence-sensor RadExpand 5 - power arrives smoothly in proportion to your effort instead of surging on a delay.
  • The 720Wh Safe Shield battery is UL 2271 certified and resin-potted for fire safety, and its 60-mile max range is excellent for a folder.
  • The 50mm hydraulic suspension fork plus 4-inch fat tires make it far more comfortable on gravel, boardwalks, and rough pavement than rigid folding rivals.
  • Hydraulic disc brakes with 180mm rotors are a genuine upgrade over the mechanical brakes on cheaper folding fat bikes.
  • The low-slung step-thru frame and adjustable stem fit a huge range of riders, making it a great shared bike for couples or RV guests.
  • It ships with everything included - fenders, 59-lb rack, lights with brake light, and folding pedals - so there is nothing to add for daily use.
  • The 315-lb payload and stout frame handle bigger riders plus loaded panniers without feeling flexy.
  • Rad's two-year warranty and established parts and service network beat the support you get from most folding-bike-only brands.

Cons

  • At 72.5 lbs it is punishingly heavy for a folding bike - it folds fine, but lifting it into a trunk or RV compartment usually takes two people.
  • It is Class 2 only with a 20 mph cap and no official way to unlock higher speeds, which frustrates riders used to 28 mph commuters.
  • The 64Nm of torque is modest for a 750W fat bike - steep climbs with a heavy load require dropping to low gears and patience.
  • The 225-lb max rider weight within the payload rating rules out some of the heavier riders the fat-tire category usually attracts.
  • The ~50-lumen headlight is weak for anything beyond being seen - riders who commute in the dark will want a brighter aftermarket light.
  • The folded package is still bulky at 29 x 25 x 41 inches - it fits an SUV or RV bay but overwhelms small car trunks.
  • Fat tires plus a 7-speed drivetrain make unassisted pedaling above 15 mph feel like a workout if the battery dies.
  • At $1,899 it costs several hundred dollars more than Lectric's comparable folding fat bikes, and you are paying partly for the brand and service network.
