Built for where pavement ends

The BroPath 73D is the all-terrain flagship of the lineup, rolling on 20x4.0-inch fat tires that float over soft sand, packed snow, and loose trail. Where a city bike would sink, the 73D keeps moving forward.

Fat tires, real grip

Those 4.0-inch tires spread your weight over a wide contact patch, giving stability on sketchy surfaces and confidence on climbs. Lower tire pressure lets the rubber conform to bumps, smoothing out rough ground that would rattle a standard e-bike.

Flagship value at $598

At $598 with a compare-at price of $1119, the 73D delivers fat-tire capability without a premium-bike bill. It is the right pick if your rides mix town and terrain, or if the roads near you turn snowy in winter.

A few fat-tire riding tips

Start with lower pressure than you would on a road bike; softer tires grip loose ground better and absorb vibration. On sand, keep a steady throttle and avoid sharp turns, and on snow, give yourself extra braking distance. The wide tires forgive a lot, but momentum is your friend on soft surfaces.

Who the 73D is for

If your weekends mean beaches, packed trails, or unplowed streets, the 73D earns its place. It is heavier than a folding city bike, so it is less ideal for train commutes, but for riders who want one bike that refuses to be stopped by terrain, it is the clear pick.

Part of a complete lineup

For pure city commuting, the BroPath Q5 offers a 500W motor and minimalist style. If folding and storage matter most, the BroPath A6 adds a basket and a tidy fold at $249.

Ship and ride

Orders ship from a US warehouse in about 5 business days. The 73D is the go-anywhere fat-tire e-bike for riders who refuse to stay on the pavement.
