Our verdict

This tricycle trades two-wheel agility for stability and cargo space, a sound trade for adults who want a steady ride on rough terrain rather than a comfort bike.

Overview

This Masiunoz model is a 20 inch fat tire adult tricycle, not a two-wheel comfort bike despite where it is filed. It runs a 7-speed drivetrain, dual disc brakes and a high carbon steel frame rated to 450 pounds, built for three-wheel stability on snow, gravel or uneven ground.

Three wheels and wide fat tires trade the speed and lean-in cornering of a two-wheel bike for stability at low speed and on loose surfaces, which is the appeal for riders who want a steadier platform. Masiunoz backs that up with a rear cargo basket and a waterproof canvas bag, positioning it as much for hauling groceries as for recreational riding. The seat and handlebars adjust for height, but a trike's turning radius and storage footprint are larger than a standard bike.

  • 20 inch fat tires for snow and gravel
  • Adjustable shock-absorbing seat and handlebars
  • High carbon steel frame, dark blue finish
  • Rear basket sized 12 x 20 x 9 inches

Who it's for

Adult riders wanting extra low-speed stability on snow, gravel or mixed terrain, plus built-in cargo capacity for errands, are the target buyer. Anyone hoping for a lightweight, agile two-wheel comfort bike is better served elsewhere, since this is a tricycle.

Pros and cons

Pros
  • 7-speed drivetrain for varied terrain
  • Dual disc brakes for load control
  • 450 lb frame weight capacity
  • Cargo basket plus waterproof canvas bag included
Cons
  • Three wheels mean a wider turning radius than a bike
  • Fat tire tricycles are heavier and harder to store
  • Listed under Comfort Bikes despite being a tricycle

Performance notes

Power comes from pedaling through a 7-speed rear chain, letting riders shift for grade changes rather than relying on a single gear. The dual disc brake system with aluminum brake levers is meant to hold speed and direction under load, including when the rear basket is loaded, and the high carbon steel frame is rated to support up to 450 pounds. Wide 20 inch fat tires are built for traction on snow and gravel rather than pavement speed.
